Description

Technical Field

[0001] This application relates to the field of Internet technologies, and in particular, to a method, apparatus, electronic device, storage medium, and product for obtaining address information. Background Art

[0002] Currently, in many scenarios, it is necessary to obtain the address information of users. For example, when users sign up for an exam or get vaccinated online, in these scenarios, it is necessary to obtain address information such as the province, city, district, county, town, and street where the user is located. And this address information is generally stored in a database. Therefore, when obtaining the address information of a user, the database needs to be queried.

[0003] In related technologies, when obtaining the target province information, the server sends a fetch request to the database, and the database returns the province information of multiple provinces to the server. Then the server determines the target province information from the multiple province information. When obtaining the target city information, the server sends a fetch request to the database again, and the database returns the city information of multiple cities under the target province information to the server. Then the server determines the target city information from the multiple city information. And so on, to obtain the address information such as the province, city, district, county, town, and street where the user is located level by level.

[0004] However, in the process of obtaining address information by the method in related technologies, the server needs to interact with the database multiple times, and each interaction requires a certain amount of time.

In the embodiment of this application, no specific limitation is made on the first address information.

[0127] In a possible implementation manner, the terminal displays a query interface, and a query box is displayed on the query interface. The number of the query boxes can be one or more. When the number of the query boxes is multiple, the multiple query boxes are used to query the address information of different levels one by one. For example, the number of the multiple query boxes is 5. The first query box is used to query the address information of the provinces, autonomous regions or municipalities directly under the Central Government included in the country. The second query box is used to query the address information included in the province, autonomous region or municipality directly under the Central Government in the first query box. The third query box is used to query the address information of the prefecture-level cities or autonomous prefectures corresponding to the first two query boxes. The fourth query box is used to query the address information of the districts, county-level cities or counties corresponding to the first three query boxes. The fifth query box is used to query the address information of the townships, towns and streets corresponding to the first four query boxes.

[0128] When the first query box is triggered, the terminal sends a fourth acquisition request to the server. The server obtains a third query condition from the fourth acquisition request, and this third query condition is used to query the address information of provinces, autonomous regions or municipalities directly under the Central Government included in the country. The server sends a fifth acquisition request to the database based on the third query condition. The database obtains all the address information of provinces, autonomous regions or municipalities directly under the Central Government based on this fifth acquisition request, returns all the address information of provinces, autonomous regions or municipalities directly under the Central Government to the server, and the server then returns all the address information of provinces, autonomous regions or municipalities directly under the Central Government to the terminal. The terminal displays all the address information of provinces, autonomous regions or municipalities directly under the Central Government on the interface. The user can select a target province, a target autonomous region or a target municipality directly under the Central Government from this address information of provinces, autonomous regions or municipalities directly under the Central Government. When the second query box is triggered, the terminal sends a third acquisition request to the server. The server receives the third acquisition request and executes step 302.

[0129] Among them, after the server obtains the address information of provinces, autonomous regions or municipalities directly under the Central Government, it can cache this address information locally. When obtaining it again later, there is no need to query the database again, which takes less time and has higher efficiency in obtaining address information.

[0130] In this implementation manner, the number of multiple query boxes can be 4. These 4 query boxes are respectively used to query the address information of provinces, autonomous regions or municipalities directly under the Central Government included in the country, the address information included in provinces, autonomous regions or municipalities directly under the Central Government, the address information included in prefecture-level cities or autonomous prefectures, and the address information included in districts, county-level cities or counties. Or, the number of multiple query boxes can be 3. These 3 query boxes are respectively used to query the address information of provinces, autonomous regions or municipalities directly under the Central Government included in the country, the address information included in provinces, autonomous regions or municipalities directly under the Central Government, and the address information included in prefecture-level cities or autonomous prefectures.

[0131] In the embodiments of the present application, the number of query boxes can be set and changed according to needs. For example, when a user signs up for an exam online and selects an exam location, and the exam location is set in different districts, county-level cities and counties of a prefecture-level city, in this case, the number of query boxes can be set to 3. Another example is that when a user gets vaccinated and detailed address information of the user is required, in this case, the number of query boxes can be set to 5.

[0132] In another possible implementation, a hierarchical address information is displayed on the terminal, and multiple query boxes are also displayed. The multiple query boxes are used to query the address information of different levels under this level one by one. For example, if the address information of the level displayed on the terminal is the address information of a province, the number of multiple query boxes can be 4. These 4 query boxes are respectively used to query the address information included in the prefecture-level cities or autonomous prefectures under this province, the address information included in a prefecture-level city or autonomous prefecture, the address information included in a district, county-level city or county, and the address information included in a township, town and street. When the first query box is triggered, the terminal sends a third acquisition request to the server, and the server receives the third acquisition request and executes step 302.

[0133] For another example, if the address information of the level displayed on the terminal is the address information of a prefecture-level city in a province, the number of multiple query boxes can be 3. These 3 query boxes are respectively used to query the address information included in this prefecture-level city, the address information included in a district, county-level city or county, and the address information included in a township, town and street. When the first query box is triggered, the terminal sends a third acquisition request to the server, and the server receives the third acquisition request and executes step 302.

[0134] For another example, if the address information of the level displayed on the terminal is the address information included in a district in a prefecture-level city of a province, the number of multiple query boxes can be 2. These 2 query boxes are respectively used to query the address information included in this district and the address information included in a township, town and street. When the first query box is triggered, the terminal sends a third acquisition request to the server, and the server receives the third acquisition request and executes step 302.

[0135] Step 302: The server responds to the third acquisition request and acquires a first query condition.

[0136] The third acquisition request carries third address information. The server determines the first query condition based on the third address information in the third acquisition request. The first query condition is used to query the first address information. For example, if the user wants to query which prefecture-level cities are included in Hebei Province through the terminal, the terminal sends a third acquisition request. The third acquisition request carries the address identifier of "Hebei Province", then the server determines the first query condition based on the address identifier of "Hebei Province" to query the address information included in Hebei Province.

[0137] Step 303: The server determines the first level of the first address information.

[0138] If the first address information queried by the first query condition is the address information included in a province, autonomous region, or municipality directly under the Central Government, determine that the first level of the first address information is the prefecture-level administrative level, which includes prefecture-level cities and autonomous prefectures. If the first address information queried by the first query condition is the address information included in a prefecture-level city or autonomous prefecture, determine that the first level of the first address information is the county-level administrative level, which includes districts, county-level cities, and counties. If the first address information queried by the first query condition is the address information included in a district, county-level city, or county, determine that the first level of the first address information is the township-level administrative level, which includes townships, towns, and sub-districts. If the first address information queried by the first query condition is the address information included in a township, town, or sub-district, determine that the first level of the first address information is the village-level administrative level, which includes communities and villages.

[0139] Thus, the server determines the address information with the lowest level from the first query condition, and uses the level one lower than this address information level as the first level. That is, if the first address information queried by the first query condition is the address information included in the provincial administrative level, and the level one lower than this provincial administrative level is the prefecture-level administrative level, then the first level of the first address information is the prefecture-level administrative level; if the first address information queried by the first query condition is the address information included in the prefecture-level administrative level, then the first level of the first address information is the county-level administrative level; if the first address information queried by the first query condition is the address information included in the county-level administrative level, then the first level of the first address information is the township-level administrative level. If the first address information queried by the first query condition is the address information included in the township-level administrative level, then the first level of the first address information is the village-level administrative level.

[0140] For example, if the first address information queried by the first query condition is the address information included in Hebei Province, and the only address information in this first query condition is "Hebei Province", and "Hebei Province" belongs to the provincial administrative level, and the level one lower than this provincial administrative level is the prefecture-level administrative level, then the server determines that the first level of the first address information is the prefecture-level administrative level. Another example, if the first address information queried by the first query condition is the address information included in Shijiazhuang City, Hebei Province, since the address information with the lowest level in the first query condition is "Shijiazhuang City", and "Shijiazhuang City" belongs to the prefecture-level administrative level, then the first level of the first address information is the county-level administrative level.

[0141] It should be noted that the provincial administrative level also includes special administrative regions. Here, only the provincial administrative level including provinces, autonomous regions, and municipalities directly under the Central Government is taken as an example for illustration. The prefecture-level administrative level also includes regions and leagues. Here, only the prefecture-level administrative level including prefecture-level cities and autonomous prefectures is taken as an example for illustration. The county-level administrative level also includes autonomous counties, autonomous banners, banners, and special zones. Here, only the county-level administrative level including districts, county-level cities, and counties is taken as an example for illustration. The township-level administrative level also includes ethnic townships, ethnic sumus, sumus, and town-level cities. Here, only the township-level administrative level including townships, towns, and sub-districts is taken as an example for illustration. The village-level administrative level also includes gachas. Here, only the village-level administrative level including communities and villages is taken as an example for illustration.

[0142] It should be noted that if the first level is the village-level administrative level, since the village-level administrative level is the lowest administrative level, the server can directly obtain the corresponding first address information from the database based on the first query condition. In this case, there is no need to determine the second level anymore.

[0143] Step 304: The server determines at least one second level lower than the first level based on the first level.

[0144] In the embodiments of the present application, the levels of the provincial administrative level, prefecture-level administrative level, county-level administrative level, township-level administrative level, and village-level administrative level are gradually from high to low.

[0145] The server can determine the level one level lower than the first level to obtain at least one second level, or can determine the levels one level and two levels lower than the first level to obtain at least one second level, or can determine all the levels lower than the first level to obtain at least one second level. Correspondingly, the third acquisition request also carries the scene information of the current scene. The server determines which level of address information is the address information that finally needs to be obtained based on the scene information of the current scene, then determines the difference between the first level and this level to obtain the level difference, and then takes the levels lower than the first level and with a level difference not greater than the corresponding level difference as at least one second level.

[0146] For example, if the first level is the prefecture-level administrative level and the level number is 1, then the second level is the county-level administrative level one level lower than the prefecture-level administrative level. Another example, if the first level is the prefecture-level administrative level and the level number is 2, then the second level is the county-level administrative level one level lower than the prefecture-level administrative level and the township-level administrative level two levels lower than the prefecture-level administrative level. Another example, if the first level is the prefecture-level administrative level and the level number is 3, then the second level is the county-level administrative level one level lower than the prefecture-level administrative level, the township-level administrative level two levels lower than the prefecture-level administrative level, and the village-level administrative level three levels lower than the prefecture-level administrative level. Another example, if the first level is the county-level administrative level and the level number is 1, then the second level is the township-level administrative level one level lower than the county-level administrative level.

[0147] Alternatively, the interface information of the current interface is also carried in the third acquisition request. Based on the interface information of the current interface, the server determines which level of address information is the final address information to be acquired, then determines the difference between the first level and this level to obtain the level difference, and then uses the level lower than the first level and with a level difference from the first level not greater than this level difference as at least one second level.

[0148] Alternatively, the server determines the number of query boxes to be queried in the current interface based on the interface information of the current interface, and determines the level difference based on the number of query boxes to be queried. Among them, the query boxes to be queried include the query box for querying the first address information. If the number of query boxes to be queried is 4, the level difference is determined to be 3. If the number of query boxes to be queried is 3, the level difference is determined to be 2. That is, the level difference is 1 less than the number of query boxes to be queried.

[0149] Step 305: The server determines at least one second query condition based on at least one second level.

[0150] The server uses at least one second level as at least one second query condition, and each second query condition is used to query the address information of one level.

[0151] Since the query of address information generally transitions from a high level to a low level gradually, in the embodiments of the present application, when acquiring the first address information, the second address information corresponding to the second level lower than the first level of the first address information is also acquired. In this way, when acquiring the address information of the second level later, there is no need to interact with the database again, shortening the response time, and thus improving the acquisition efficiency of the address information. Moreover, when acquiring the second address information based on the second level, there is no need to traverse the database to find out which address information corresponds to the first address information, which can further shorten the response time, and thus improve the acquisition efficiency of the address information.

[0152] Step 306: The server acquires the corresponding first address information and each second address information from the database based on the first query condition and each second query condition.

[0153] In this step, the server acquires the address information corresponding to the first level and the second address information corresponding to each second level from the database based on the first query condition and each second query condition, and then acquires the first address information from the address information corresponding to the first level.

[0154] That is, if the first level is the prefecture-level administrative level and the second level is the county-level administrative level, the server acquires the address information corresponding to the prefecture-level administrative level and the address information corresponding to the county-level administrative level from the database, and then acquires the first address information from the address information corresponding to the prefecture-level administrative level.

[0155] If the first level is the prefecture-level administrative level and the second level is the county-level administrative level and the township-level administrative level, the server obtains the address information corresponding to the prefecture-level administrative level, the second address information corresponding to the county-level administrative level, and the second address information corresponding to the township-level administrative level from the database, and then obtains the first address information from the address information corresponding to the prefecture-level administrative level.

[0156] If the first level is the prefecture-level administrative level and the second level is the county-level administrative level, the township-level administrative level, and the village-level administrative level, the server obtains the address information corresponding to the prefecture-level administrative level, the second address information corresponding to the county-level administrative level, the second address information corresponding to the township-level administrative level, and the second address information corresponding to the village-level administrative level from the database, and then obtains the first address information from the address information corresponding to the prefecture-level administrative level.

[0157] If the first level is the county-level administrative level and the second level is the township-level administrative level, the server obtains the address information corresponding to the county-level administrative level and the second address information corresponding to the township-level administrative level from the database, and then obtains the first address information from the address information corresponding to the county-level administrative level.

[0158] If the first level is the county-level administrative level and the second level is the township-level administrative level and the village-level administrative level, the server obtains the address information corresponding to the county-level administrative level, the second address information corresponding to the township-level administrative level, and the second address information corresponding to the village-level administrative level from the database, and then obtains the first address information from the address information corresponding to the county-level administrative level.

[0159] If the first level is the township-level administrative level and the second level is the village-level administrative level, the server obtains the address information corresponding to the township-level administrative level and the second address information corresponding to the village-level administrative level from the database, and then obtains the first address information from the address information corresponding to the township-level administrative level.

[0160] In a possible implementation, when the server obtains the address information from the database, it sends a second acquisition request to the database. The second acquisition request carries a first query condition and each second query condition. The database receives the second acquisition request and, based on the first query condition and each second query condition, obtains the address information corresponding to the first level and the second address information corresponding to each second level, and then the database sends the address information corresponding to the first level and the second address information corresponding to each second level to the server.

[0161] In this implementation, the server can obtain the corresponding address information by interacting with the database only once, shortening the response time and thus improving the acquisition efficiency of the address information.

[0162] In the embodiments of the present application, different provinces, autonomous regions, and municipalities directly under the Central Government have different address identifiers. Different prefecture-level cities and autonomous prefectures under the same province, autonomous region, or municipality directly under the Central Government have different address identifiers. Different districts, county-level cities, and counties under the same prefecture-level city or autonomous prefecture also have different address identifiers. Different townships, towns, and sub-districts under the same district, county-level city, or county also have different address identifiers. Different villages and communities under the same township, town, or sub-district also have different address identifiers. Based on this, the server can obtain the address information corresponding to the address identifier from the address information corresponding to the first level based on the address identifier in the first address information, and obtain the first address information.

[0163] For example, the first address information queried by the first query condition is the address information included in Hebei Province. The first level is the prefecture-level administrative level, and the second level is the county-level administrative level and the township-level administrative level. The server obtains the address information corresponding to the prefecture-level administrative level, the second address information corresponding to the county-level administrative level, and the second address information corresponding to the township-level administrative level from the database. Since the address information corresponding to the prefecture-level administrative level includes not only the address information under Hebei Province but also the address information under other provinces, in this case, the server obtains the address information under Hebei Province from the address information under Hebei Province and the address information under other provinces based on the address identifier of Hebei Province, that is, obtains the prefecture-level cities and autonomous prefectures included in Hebei Province.

[0164] In the embodiments of the present application, when querying the first address information, determine the first level of the first address information, obtain the address information based on the first level of the first address information, and then obtain the first address information from the address information corresponding to the first level. Since the address information at different levels in the database is regular, it is possible to parse whether the address information is a province or a city from the composition rule, and logically optimize the query SQL (Structured Query Language). By optimizing the SQL to query all address information such as provinces, cities, districts, and sub-districts, the fewer the conditions, the faster the SQL statement queries. In this way, there is no need to traverse the database to query the first address information, shortening the response time, and thus improving the query efficiency of the SQL statement.

[0165] Step 307: The server caches each second address information locally on the server.

[0166] After the server obtains each second address information, it can cache each second address information locally on the server, and can also cache the address information corresponding to the first level locally on the server.

[0167] In an embodiment of the present application, after the server obtains the address information from the database, it caches the address information locally on the server. In this way, when the address information is subsequently obtained, it can be directly obtained from the local server without the need to interact with the database, thereby shortening the response time and improving the efficiency of obtaining the address information.

[0168] One thing that needs to be explained is that after the server obtains the address information from the database, it can cache the address information locally on the server in the form of a hierarchical matching tree. The process can be:

[0169] The server determines that the address information obtained from the database belongs to the same province, autonomous region or municipality, and obtains address information with an associated relationship; determines that the address information obtained from the database belongs to the same prefecture-level city or autonomous prefecture, and obtains address information with an associated relationship; determines that the address information obtained from the database belongs to the same district, county-level city and county, and obtains address information with an associated relationship; determines that the address information obtained from the database belongs to the same township, town or street, and obtains address information with an associated relationship; determines that the address information obtained from the database belongs to the same community or village, and obtains address information with an associated relationship. The server connects two nodes based on the address information with an associated relationship and the hierarchy of each address information to obtain a hierarchical matching tree. In the hierarchical matching tree, the hierarchy of the address information represented by the parent node is higher than the hierarchy of the address information represented by the child node.

[0170] For example, Shijiazhuang City and Xingtai City are both address information under Hebei Province, Zhengzhou City and Kaifeng City are both address information under Henan Province, then Shijiazhuang City and Xingtai City are address information with associated relationship, and Zhengzhou City and Kaifeng City are address information with associated relationship. For another example, Zanhuang County and Xingtang County are both address information under Shijiazhuang City, Lankao County and Qi County are both address information under Kaifeng City, then Zanhuang County and Xingtang County are address information with associated relationship, and Lankao County and Qi County are address information with associated relationship.

[0171] The server determines through the above method that the address information with an associated relationship is address information belonging to the same level, but the address information locally cached by the server includes address information of different levels. In this case, the server uses the address information of two adjacent levels with an associated relationship as nodes, connects the two nodes, and obtains a hierarchical matching tree.

[0172] For example, Zanhuang County and Xingtang County are address information with an associated relationship. Both belong to the address information under Shijiazhuang City. Then, connect the nodes represented by Shijiazhuang City to the nodes represented by Zanhuang County and Xingtang County respectively. The level corresponding to Shijiazhuang City belongs to the prefecture-level administrative level, and the levels corresponding to Zanhuang County and Xingtang County belong to the county-level administrative level. Since the prefecture-level administrative level is higher than the county-level administrative level, the node represented by Shijiazhuang City serves as the parent node, and the nodes represented by Zanhuang County and Xingtang County serve as child nodes.

[0173] It should be noted that among the provincial administrative level, prefecture-level administrative level, county-level administrative level, township-level administrative level, and village-level administrative level, the provincial administrative level is the highest. Therefore, the server uses the address information corresponding to the provincial administrative level as the top node, and this top node can be used to identify the level matching tree. For example, both Shijiazhuang City and Xingtai City belong to the address information under Hebei Province, and Hebei Province belongs to the provincial administrative level. Then, the server uses the node represented by Hebei Province as the top node of the level matching tree.

[0174] In addition, since the address information cached locally by the server includes address information at each level under different provinces, autonomous regions, and municipalities directly under the Central Government, and there is no associated relationship between the address information at each level under different provinces, autonomous regions, and municipalities directly under the Central Government, multiple level matching trees can be obtained through the above method. For example, the address information at each level under Hebei Province forms a level matching tree, and the address information at each level under Henan Province forms another level matching tree.

[0175] In the embodiment of the present application, the server caches the address information locally in the form of a level matching tree based on the JavaScript flat-to-tree algorithm. Translated into Java code, it can reduce the algorithm complexity and is beneficial for subsequent querying of address information.

[0176] Step 308: The server returns the first address information to the terminal.

[0177] After the server obtains the first address information, it can return the first address information to the terminal, and the terminal displays the first address information on the query interface. For example, if the first address information is used to query the address information included in Hebei Province, the terminal displays the prefecture-level cities and autonomous prefectures included in Hebei Province on the query interface.

[0178] Step 309: The terminal sends a first acquisition request for obtaining the second address information to the server.

[0179] The user can select target address information from the query box that displays the first address information on the terminal, and then determine the address information included in the next query box based on the selected target address information. When the terminal detects that the next query box is triggered, it sends a first acquisition request to the server. For example, the first address information is used to query the address information included in Hebei Province. The terminal displays the prefecture-level cities included in Hebei Province, and the user selects the corresponding prefecture-level city from these prefecture-level cities. For example, the user selects Shijiazhuang City as the target address information, and then triggers the next query box, that is, to query the address information included in Shijiazhuang City. In this case, the terminal sends a first acquisition request to the server. Among them, the first acquisition request sent by the terminal to the server is used to acquire address information with the address information currently displayed on the terminal as a prerequisite.

[0180] Step 310: In response to the first acquisition request, the server acquires the second address information corresponding to the first acquisition request from the server local.

[0181] This step can be implemented through the following steps (1) to (2), including:

[0182] (1) In response to the first acquisition request, the server determines a first logical query statement for acquiring the second address information.

[0183] Based on the first acquisition request, the server determines a first logical query statement, and the first logical query statement includes address information at different levels. For example, if the address information currently displayed on the terminal is Hebei Province and Shijiazhuang City, then the address information carried in the first acquisition request is "Hebei Province" and "Shijiazhuang", and the first logical query statement is used to query the address information included in Shijiazhuang City, Hebei Province. Among them, "Hebei Province" and "Shijiazhuang City" belong to address information at different levels.

[0184] (2) The server determines the second address information from multiple hierarchical matching trees in the server local based on the first logical query statement.

[0185] Step (2) can be implemented through the following steps (2-1) to (2-3), including:

[0186] (2-1) The server determines the address information with the highest level and the address information with the lowest level in the first logical query statement based on the first logical query statement.

[0187] As can be seen from step (1), the first logical query statement includes address information at different levels. The server can determine the highest-level address information and the lowest-level address information based on the positions of the address information at different levels in the first logical query statement. The earlier the address information is in the first logical query statement, the higher its corresponding level. Therefore, the server takes the address information in the first position of the first logical query statement as the highest-level address information and the address information in the last position as the lowest-level address information.

[0188] For example, if the first logical query statement is used to query the address information included in Shijiazhuang City, Hebei Province, "Hebei Province" is in the most forward position, so "Hebei Province" is taken as the highest-level address information, and "Shijiazhuang City" is in the most backward position, so "Shijiazhuang City" is taken as the lowest-level address information. Another example, if the first logical query statement is used to query the address information included in Zanhuang County, Shijiazhuang City, Hebei Province, "Hebei Province" is in the most forward position, so "Hebei Province" is taken as the highest-level address information, and "Zanhuang County" is in the most backward position, so "Zanhuang County" is taken as the lowest-level address information.

[0189] (2-2) Based on the highest-level address information, the server determines, from multiple level matching trees in the server local, the level matching tree with the top node being the highest-level address information as the target level matching tree.

[0190] From the process of determining the level matching tree in step 307, it can be seen that the top node can be used to identify the level matching tree, and the node represented by the highest-level address information is the top node. Therefore, the server can search in multiple level matching trees for the level matching tree with the top node being the highest-level address information and take this level matching tree as the target level matching tree.

[0191] (2-3) Based on the lowest-level address information, the server determines, from the target level matching tree, the address information corresponding to the node with the lowest-level address information as the parent node as the second address information.

[0192] After the server determines the target level matching tree, it takes the node represented by the lowest-level address information as the parent node and determines the address information corresponding to the child nodes included in this parent node as the second address information.

[0193] Continuing with the example where the first logical query statement is used to query the address information included in Shijiazhuang City, Hebei Province, the server determines the target level matching tree corresponding to "Hebei Province" from multiple level matching trees corresponding to "Hebei Province", "Henan Province", "Shanxi Province", etc., and then determines, from the target level matching tree corresponding to "Hebei Province", the address information corresponding to multiple child nodes with "Shijiazhuang City" as the parent node, such as "Zanhuang County", "Xingtang County", etc., and takes the address information corresponding to these child nodes as the second address information.

[0194] In the embodiments of the present application, by performing a query based on a hierarchical matching tree and a logical query statement, the corresponding second address information can be quickly found locally, further shortening the response time and thus further improving the acquisition efficiency of the address information.

[0195] In the embodiments of the present application, the address information may change. Based on this, the server can update the address information cached locally every preset time period. The process is as follows: Determine the storage duration of the address information cached locally. When the storage duration reaches the preset time period, re-obtain the address information from the database, and based on the re-obtained address information, update the address information cached locally.

[0196] In this implementation manner, when the server determines that the storage duration reaches the preset time period, it can re-obtain the address information corresponding to the first level and the second address information corresponding to each second level from the database, then delete all the address information cached locally, and cache the re-obtained address information locally.

[0197] Alternatively, when the server determines that the storage duration reaches the preset time period, it re-obtains the address information corresponding to the first level and the second address information corresponding to each second level from the database, then determines the changed address information from the re-obtained address information, replaces the original address information with the changed address information, and then updates the address information cached locally.

[0198] Alternatively, when the server determines that the storage duration reaches the preset time period, it deletes the address information cached locally, and then when receiving a acquisition request sent by the terminal, based on the acquisition request, re-obtains the address information from the database and caches the re-obtained address information locally.

[0199] Among them, the preset time period can be set and changed as needed. For example, the preset time period is 5 minutes or 10 minutes. By setting a shorter preset time period, the real-time performance of address information update can be improved, ensuring that the address information obtained by the user is the latest address information.

[0200] In another possible implementation manner, the server updates the address information cached locally only when the address information in the database changes. The process is as follows: When the address information in the database changes, a notification message is sent to the server. In response to receiving the notification message sent by the database, the server obtains the address information that has changed in the database from the notification message; based on the address information that has changed in the database, the server updates the address information cached locally.

[0201] In this implementation mode, the address information in the local cache is updated only when the address information in the database changes. This can not only avoid repeatedly obtaining address information from the database and wasting resources, but also ensure that the address information obtained by the user is the latest address information.

[0202] In the embodiment of the present application, the server can also update the address information in the local cache in other ways, and no specific limitation is made thereto.

[0203] Step 311: The server returns the second address information to the terminal.

[0204] The server sends the second address information to the terminal, and the terminal displays the second address information on the query interface.

[0205] The server can obtain the second address information level by level based on the above method until the second address information at the lowest level is obtained, that is, the second address information corresponding to the village-level administrative level. Although the village-level administrative level is the lowest level, the address information at the village-level administrative level also includes more detailed address information. For example, the address information of the communities includes the address information of the residential areas. The address information in the database only covers the address information corresponding to the village-level administrative level. Based on this, the terminal can provide an input box on the query interface, and the input box is used to input detailed address information such as the address information of the residential area or the office building, so as to accurately obtain the address information of the user.

[0206] The embodiment of the present application provides an address information acquisition method. When acquiring the first address information, the method also acquires the second address information of the second level different from the first level according to the first level of the first address information, and caches the second address information locally. In this way, when acquiring the second address information, it can be directly obtained from the local, without interacting with the database again, saving time, and thus improving the acquisition efficiency of the address information.

[0207] Moreover, in the embodiment of the present application, the address information corresponding to the level is acquired from the database based on the level of the address information, rather than directly acquiring all the address information included in a province or all the address information included in a city from the database. For example, when directly acquiring the address information of the prefecture-level cities, districts, county-level cities, and counties, and the address information of townships, towns, and streets included in Hebei Province from the database, it needs to be implemented based on nested loops. This method needs to traverse the address information in the database and establish a cubic-level link with the database to achieve. Therefore, the time for this method to acquire address information is relatively long, and the algorithm complexity is relatively high.

[0208] The method provided by the embodiments of the present application is implemented based on the hierarchy of address information. When obtaining address information, it is not necessary to traverse the database. Only one logical query needs to be established to cache the address information locally, and then the construction of the hierarchical matching tree is completed, optimizing the original response time of 30 to 40 seconds to several hundred milliseconds, greatly improving the efficiency of obtaining address information.

[0209] Figure 4 It is a flowchart of a method for obtaining address information provided by the embodiments of the present application, which is executed by a terminal and a server. This embodiment is described by taking the terminal caching the address information to the local of the terminal as an example. As Figure 4 shown, the method includes:

[0210] Step 401: The terminal sends a third acquisition request for acquiring the first address information to the server.

[0211] Step 402: The server responds to the third acquisition request and acquires the first query condition.

[0212] Step 403: The server determines the first hierarchy of the first address information.

[0213] Step 404: The server determines the hierarchies lower than the first hierarchy based on the first hierarchy to obtain at least one second hierarchy.

[0214] Step 405: The server determines at least one second query condition based on at least one second hierarchy.

[0215] Steps 401 to 405 are the same as steps 301 to 305 respectively, and will not be elaborated here.

[0216] Step 406: The server acquires the address information corresponding to the first hierarchy and the second address information corresponding to each second hierarchy from the database based on the first query condition and each second query condition.

[0217] This step is the same as the step in which the server acquires the address information corresponding to the first hierarchy and the second address information corresponding to each second hierarchy in step 306, and will not be elaborated here.

[0218] Step 407: The server sends the address information corresponding to the first hierarchy and the second address information corresponding to each second hierarchy to the terminal.

[0219] Step 408: The terminal receives the address information corresponding to the first hierarchy and the second address information corresponding to each second hierarchy, acquires the first address information from the address information corresponding to the first hierarchy, and caches the second address information corresponding to each second hierarchy to the local of the terminal.

[0220] The process by which the terminal obtains the first address information from the address information corresponding to the first level is similar to the process by which the server obtains the first address information from the address information corresponding to the first level, which will not be elaborated here.

[0221] The process by which the terminal caches the second address information corresponding to each second level to the local of the terminal is similar to the process by which the server caches the second address information corresponding to each second level to the local of the server, which will not be elaborated here.

[0222] Among them, when the terminal caches the second address information corresponding to each second level to the local of the terminal, it also caches the address information corresponding to the first level to the local of the terminal.

[0223] Step 409: In response to the operation of obtaining the second address information, the terminal obtains the corresponding second address information from the local of the terminal.

[0224] After the terminal obtains the first address information from the address information corresponding to the first level, it can display the first address information. The user can select the target address information from the query box for displaying the first address information on the terminal, and then determine the address information included in the next query box based on the selected target address information. When the terminal detects that the next query box is triggered, it determines that the operation of obtaining the second address information is detected. In response to this obtaining operation, the terminal obtains the corresponding second address information from the local of the terminal.

[0225] Among them, the process by which the terminal obtains the second address information from the local of the terminal is similar to the process by which the server obtains the second address information from the local of the server in step 310, which will not be elaborated here.

[0226] In the embodiment of the present application, the terminal caches the address information corresponding to the first level and each second address information to the local of the terminal. In this way, the terminal can directly obtain the address information from the local of the terminal subsequently, without interacting with the server and the database anymore, shortening the response time, and thus improving the efficiency of obtaining the address information.
