[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0026] Taking funds as an example, the full market fund sales system is a system for conducting fund transactions for a large number of Internet users. Tens of thousands of public funds support real-time online purchases. As the preferred tool for most users to purchase funds, the full fund list provides a wealth of fund sales information and convenient sorting, filtering and paging functions. In the fund industry, users conduct personalized queries among a large number of funds. In related technologies, they directly initiate query access to the application service and sink the logic to the database for corresponding conditional screening to complete fund data acquisition.

[0027] Faced with the real-time data query services for tens of thousands of funds by massive Internet customers, the existing technical services in fund sales scenarios have two main problems: First, the underlying data of the real-time query service is stored in multiple large tables, and personalized queries need to be associated with these tables, resulting in slow interface response rate and extended response time. Secondly, although cache-based data storage in related technologies can solve some of the response rate problems, once a large number of users access it at the same time, the bandwidth consumption caused by cache reading may affect system performance, ultimately resulting in low efficiency of fund queries and reduced user experience.

[0028] Based on this, the embodiment of the present application provides a fund information query method. The business object can be each public fund that provides instant online trading services, and the detailed information of the business object includes the basic information data of these funds, which may include but is not limited to the code, name, net value, risk level, establishment year and fund size of each fund. The identification information of the business object can be regarded as the fund code of each fund, and the business object database can be regarded as the fund database of the entire market.

[0029] Furthermore, multiple local cache spaces are preset, including a first local cache and a second local cache. The first local cache can be regarded as a local cache of basic fund information, and the second local cache can be regarded as a sorting local cache. The local cache of basic fund information is different from the sorting local cache. Specifically, the local cache of basic fund information is used to store basic information data of each public fund that provides instant online trading services obtained from the full market fund database. Optionally, the data stored in the local cache of basic fund information is in the form of Map<String,Object> Format organized.

[0030] Sorting the identification information of the business objects to obtain the sorted identification information can be regarded as sorting the fund codes of the funds to obtain the sorted fund codes. The sorted local cache is a local cache space for storing these sorted fund codes. Optionally, the fund codes stored in the sorted local cache can be in the form of List<T> <string>The fund codes are organized in the format of [fund code 1, fund code 2, ...] after sorting and stored in the sorted local cache in reverse order.

[0031] Traversing the sorted identification information to obtain the target identification information can be regarded as traversing the sorted fund code stored in the sorted local cache to obtain the target fund code. Specifically, after the system receives the query instruction, it traverses the sorted fund code in order from the sorted local cache to obtain the target fund code. Further, in a paging manner, only part of the sorted fund code in the sorted local cache is traversed, and part of the sorted fund code is used as the target fund code. Optionally, if the user also wants to filter according to fund type, risk level, establishment year, fund size, etc., the sorted fund code can be filtered before traversing the sorted fund code to obtain the target fund code. Specifically, the corresponding sorted local cache is traversed one by one in ascending or descending order. If there is a filtering condition, the traversed fund code is queried in the local cache of fund basic information to obtain the basic information data of the fund, and the basic information data of the fund is matched and filtered according to the filtering condition. Only when the filtering condition is met, the corresponding fund code is retained and used as the target fund code.

[0032] The target details information corresponding to the target identification information is obtained from the first local cache, and the target details information is returned according to the target message structure. It can be regarded as using the target fund code traversed in the sorted local cache to obtain the basic information data of the fund corresponding to the target fund code in the local cache of the fund basic information, and return the basic information data of the fund according to the target message structure. Among them, the target message structure can refer to the order in which the backend service returns the fields based on the fund list agreed with the product-side system. The backend service directly returns the fields in the order of the agreed array [value1, value2...], where the key arrays corresponding to all value arrays are only returned once each time the message is called. The product side can match the corresponding values ​​according to the key array order corresponding to the value array and use the data.

[0033] According to an embodiment of the present application, an embodiment of a business object information query method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] In this embodiment, a method for querying business object information is provided. Figure 1 : is a flowchart of a business object information query method according to an embodiment of the present application, comprising the following steps:

[0035] S110: Store detailed information of the business object in a first local cache.

[0036] The detailed information includes the identification information of the business object. The identification information represents specific information that can uniquely identify each business object. Exemplarily, the business object can be each public fund that provides instant online trading services, and the detailed information includes the basic information data of these funds, which may include but is not limited to the code, name, net value, risk level, establishment year and fund size of each fund. Furthermore, the fund code of each fund can be used as its identification information. It is understandable that the business object can also be each document that can be publicly queried in the literature database, and the detailed information can be the basic information data of these documents, which may include but is not limited to the article title, index number, author, publication date, etc. of each document.

[0037] The first local cache refers to a cache stored in the memory of the application server, which is used to store business object details. For example, the local cache of fund basic information can be regarded as the first local cache. Specifically, the detailed information of business objects can be stored in the first local cache from the business object database using a memory data structure. For example, a hash table (HashMap) is used to store data in the first local cache in the form of key-value pairs from the full market fund database that stores all fund information. At this time, the data is in the form of Map<String,Object> The format is organized as follows, where the String type key represents the fund code and the Object represents the detailed information associated with the fund code.

[0038] S120. Sort the identification information of the business objects to obtain sorted identification information.

[0039] Specifically, a kind of attribute value data of a preset business object is used as the basis for sorting, and such attribute value data of all business objects are extracted from the first local cache, and a sorting algorithm is applied to sort such attribute value data of all extracted business objects, and based on such attribute value data of the business objects, the identification information of the business objects is arranged in a certain order to obtain sorted identification information. Exemplarily, the fund net value is used as the attribute value data of the preset business object. Based on the fund net value, the actual fund net value of each fund is extracted from the local cache of the fund basic information, and further, according to the values ​​of the actual fund net values ​​of these funds, the fund codes are sorted from high to low, and finally the sorted fund codes of all funds arranged in order from large to small according to the fund net value are obtained.

[0040] S130: Store the sorted identification information in a second local cache.

[0041] The first local cache is different from the second local cache. The second local cache may refer to a lightweight memory cache, which is also stored in the memory of the application server and is used to store sorted identification information of the business object. Specifically, after sorting the multiple attribute value data of the business object, multiple sorted local caches may be constructed, in which the sorted identification information of each attribute value data category of the business object is stored. The sorted local cache may be regarded as the second local cache. Exemplarily, the sorted local cache may be a List<T> <string>After obtaining the sorted fund codes of all funds arranged in descending order according to a certain attribute value data of the fund, the sorted fund codes are stored in the corresponding sorted local cache in reverse order according to the format of [fund code 1, fund code 2, ...].

[0042] S140, traverse the sorted identification information to obtain target identification information.

[0043] The target identification information is a specified part of the sorted identification information. Specifically, after receiving the query instruction, the sorted identification information stored in the second local cache is sequentially traversed and searched based on the query instruction to obtain the target identification information.

[0044] Exemplarily, after receiving the query instruction, the system sequentially traverses the sorted fund codes from the sorted local cache to obtain the target fund code. Optionally, a paging method can be used to traverse only part of the sorted fund codes in the sorted local cache and use the part of the sorted fund codes as the target fund code.

[0045] S150: Obtain target detail information corresponding to the target identification information from the first local cache.

[0046] The target details information refers to the details information of the business object stored in the first local cache. Specifically, the target details information is the details information of the business object obtained in the first local cache by a corresponding search method based on the target identification information obtained by traversing from the second local cache. For example, the first local cache, that is, the local cache of the basic information of the fund, is based on Map<String,Object> format, use the target fund code as the key, and perform a corresponding query to get a value, which contains the basic information data of the target fund.

[0047] S160. Return target detailed information according to the target message structure.

[0048] Among them, the target message structure includes a value list and a key list, the value list includes the value of the key of the business object in the target detail information, and the key list includes the key of the business object in the target detail information. The target message structure is an optimized data return format. Specifically, the backend service will return a value list in a predetermined order according to the agreement of the predefined field order. Since the keys of all business objects usually do not change in a process, it is only necessary to return the value list of the key of the target business object, that is, the key list, once each time the interface is called, and then the product side can parse and use the data according to the predefined field order based on this key list. Understandably, after obtaining the target detail information corresponding to the target identification information in the first local cache, the target detail information of the business object can be returned to the product side using the target message structure and displayed on the user terminal interface.

[0049] Exemplarily, after obtaining the basic information data of the target fund corresponding to the target fund code in the first local cache, that is, the local cache of the basic information of the fund, the back-end service returns the fields directly in the order of the agreed array [value1, value2...] based on the order of the fund list return fields agreed with the product-side system, where the key arrays corresponding to all value arrays are returned only once in each call message. The product side can match the corresponding values ​​according to the key array order corresponding to the value array and use the data.

[0050] In the above implementation, the target identification information is first determined by traversing the sorted identification information in the second local cache, and the target detailed information corresponding to the target identification information is obtained from the first local cache, and finally the target detailed information is returned according to the target message structure. Thus, by optimizing the data storage and query process, a method for improving the efficiency of business object information query is realized.

[0051] In some implementations, storing detailed information of the business object in the first local cache includes: updating the detailed information of the business object from a business object database to the first local cache through a scheduled task.

[0052] Specifically, an automatically programmed timer task can be used to update the business object details from the business object database to the first local cache at a predetermined time interval. Exemplarily, this timer task includes querying the business object database for new data or changed data every minute, performing an update operation, reading the latest updated business object details in the business object database, and comparing it with the business object details stored in the first local cache, identifying the data items that need to be updated, and further writing the identified new data or changed data into the first local cache to replace the old data items, thereby completing the update.

[0053] In the above implementation, the new data or changed data in the business object database is written into the first local cache by a scheduled task and the old data items are replaced at the same time, so that the data in the first local cache is always kept up to date. Furthermore, by performing operations such as sorting and querying based on the updated first local cache, the system can ensure that users can always obtain the latest data when accessing detailed information of business objects, while reducing the direct query pressure on the business object database and improving the response speed and performance of the system.

[0054] In some implementations, sorting the identification information of the business objects to obtain sorted identification information includes:

[0055] Sort the identification information of the business object to obtain sorted identification information sorted according to a preset sorting method; wherein, there are multiple preset sorting methods, the business object has multiple attribute parameters, and the preset sorting methods correspond to the attribute parameters of the business object one by one. For example, if the business object is a fund, the attribute parameters of the business object may be more than ten attribute parameters such as the unit net value of the fund, daily rise and fall, the past week, the past year, this year, and since its establishment. Similarly, by sorting the business objects according to different attribute parameters, different groups of sorted identification information of the business objects under the preset sorting methods corresponding to different attribute parameters can be obtained. Specifically, if Figure 2 As shown, the business object database 202 stores all detailed information of all business objects, the first local cache 204 stores detailed information of business objects, and the sorted identification information of business objects under different preset sorting methods corresponding to different attribute parameters is stored in different second local caches. Exemplarily, the second local cache can be an establishment time sorting cache 206, which stores sorted fund codes arranged in chronological order since the establishment of the fund; it can be a unit net value sorting cache 208, which stores sorted fund codes arranged in descending order according to the unit net value of the fund; it can be a weekly time sorting cache 210, which stores sorted fund codes arranged in chronological order according to the fund in the past week; it can be a rise and fall sorting cache 212, which stores sorted fund codes arranged in chronological order according to the size of the daily rise and fall of the fund.

[0056] In the above implementation, multiple preset sorting methods are constructed based on multiple attribute parameters of the business object to obtain multiple second local caches, so that the system can flexibly sort business objects according to user needs while ensuring fast access and processing of data to improve user experience.

[0057] In some embodiments, please refer to the attached Figure 3 , obtaining target detail information corresponding to the target identification information from the first local cache, including:

[0058] S310: Obtain initial detail information corresponding to the identification information from the first local cache.

[0059] Among them, the initial detail information may refer to the detail information of all business objects obtained in the first local cache through a corresponding search method according to the target identification information obtained by traversing from the second local cache. Specifically, after receiving the query instruction, the sorted identification information stored in the second local cache is sequentially traversed and searched based on the query instruction to obtain the target identification information. Exemplarily, after the system receives the query instruction, the sorted fund codes are traversed in order from the sorted local cache to obtain the target fund codes corresponding to all funds. Furthermore, using these fund codes as keys, a corresponding query is performed in the first local cache, that is, the fund basic information local cache, to obtain the corresponding fund basic information data, that is, the initial detail information.

[0060] S320: Match the initial detailed information according to the screening conditions to obtain target detailed information that meets the screening conditions.

[0061] The target details are displayed on the current page. There may be more than one selection of filtering conditions. For example, if the business object is a fund, the filtering conditions may be fund type, risk level, years of establishment, fund size, etc. Specifically, the filtering process is to match and filter the initial details of the business object stored in the first local cache based on all selected filtering conditions, obtain the target details that meet the filtering conditions, and display them on the current page.

[0062] In the above implementation, through the screening function, the system can provide a more personalized and efficient user experience, allowing users to quickly find the business object information of interest.

[0063] In some embodiments, please refer to the attached Figure 4 , the target details information is used to be displayed in the current page. Before traversing the sorted identification information to obtain the target identification information, the method further includes:

[0064] S410: Determine the number of pages and the current start mark.

[0065] Among them, the number of pages is the maximum number of business objects allowed to be displayed in the current page, and the current starting identifier is used to indicate the sorting position of the first identification information used for the current query operation in the sorted identification information. Specifically, the value of the number of pages can be a value set by default after the system balances the page loading time and user experience. The current starting identifier is determined by the number of pages, the order of traversing the sorted identification information, and the current number of pages. Exemplarily, the number of pages and the current starting identifier are first initialized, where the current starting identifier in ascending order can start from 0, and the current starting identifier in descending order is the number of sorted identification information stored in the second local cache.

[0066] S420, traverse the sorted identification information to obtain target identification information, including:

[0067] When the current start identifier does not exceed the range of the number of business objects, the sorted identifier information is traversed according to the number of pages and the current start identifier to obtain the target identifier information.

[0068] Specifically, in the second local cache, the sorted identification information is traversed according to the number of pages and the current starting identifier, and the identification information of the business objects is retrieved one by one to obtain the target identification information. Optionally, if there is a filtering condition, for each identification information of the retrieved business object, the first local cache will be queried to obtain the detailed information of the business object, and the detailed information will be matched with the filtering condition. Only the business objects that meet all the filtering conditions will be retained, and the sorted identification information of the business objects that do not meet the filtering conditions will be eliminated to obtain the target identification information. Furthermore, if the number of sorted identification information after filtering is less than the number of pages, then after completing the traversal of the current page, the current starting identifier is updated to the starting identifier of the next page, that is, the starting identifier value of the current page plus the number of pages, and the next page traversal operation is performed again until the target identification information obtained is greater than or equal to the number of pages.

[0069] In the above implementation, by determining the number of pages and the current starting identifier and traversing the sorted identifier information, the target identifier information is finally obtained, so that the system can achieve efficient paging and screening of a large number of business objects, ensuring that users can easily browse and retrieve required information according to their needs.

[0070] In some implementations, if the sorted identification information is in ascending order, and the current starting identification does not exceed the range of the number of business objects, the sorted identification information is traversed according to the number of pages and the current starting identification to obtain the target identification information, including:

[0071] When the current start identifier is less than or equal to the number of business objects, the sorted identifier information is traversed according to the number of pages and the current start identifier to obtain the target identifier information.

[0072] Specifically, after determining the number of pages and the current starting identifier, when the user issues an instruction to request a specific page number, the system will receive the number of pages and the current starting identifier passed by the calling service. At this time, the system will check whether the current starting identifier is greater than the number of all business objects stored in the first local cache. If so, it means that the requested page number exceeds the number of pages that can actually be displayed. At this time, the system returns an empty array, indicating that there is no more data to display; if not, it means that the requested page number can be displayed normally, then the sorted identifier information is traversed in ascending order to filter out all business objects that meet the conditions. It can be understood that during the traversal process, the system will update the starting identifier, and the starting identifier when exiting the traversal loop will be used as the current starting subscript for the next request. It is the minimum value between the subscript value at the end of the current traversal and the number of all business objects stored in the first local cache. Finally, the system returns the target identifier information obtained by the current traversal and the updated current starting subscript.

[0073] In the above implementation, for the ascending arrangement, when the current starting identifier is less than or equal to the number of business objects, the sorted identifier information is traversed according to the number of pages and the current starting identifier to obtain the target identifier information. The system can efficiently process the paging request to facilitate users to browse the entire business object detail information list step by step.

[0074] In some implementations, if the sorted identification information is in descending order, and the current starting identification does not exceed the range of the number of business objects, the sorted identification information is traversed according to the number of pages and the current starting identification to obtain the target identification information, including:

[0075] When the current start identifier is greater than zero, the sorted identifier information is traversed according to the number of pages and the current start identifier to obtain the target identifier information.

[0076] Specifically, after determining the number of pages and the current starting identifier, when the user issues an instruction to request a specific page number, the system will receive the number of pages and the current starting identifier passed by the calling service. At this time, the system will check whether the current starting identifier is less than zero. If so, it means that the requested page number exceeds the number of pages that can actually be displayed. At this time, the system returns an empty array, indicating that there is no more data to display; if not, it means that the requested page number can be displayed normally, then the sorted identifier information is traversed in descending order to filter out all business objects that meet the conditions. It can be understood that during the traversal process, the system will update the starting identifier, and the starting identifier when exiting the traversal loop will be used as the current starting index for the next request. It is obtained by subtracting the index value at the end of the current traversal from the number of all business objects stored in the first local cache, and ensure that this value is not less than 0. Finally, the system returns the target identifier information obtained by the current traversal and the updated current starting index.

[0077] In the above implementation, for the ascending order, when the current starting identifier is greater than zero, the sorted identifier information is traversed according to the number of pages and the current starting identifier to obtain the target identifier information. The system can efficiently process paging requests, and even when the current business object information is huge, it can facilitate users to browse part of the business object information in the reverse order of the second local cache, providing a variety of user experiences.

[0078] This specification also provides a method for querying business object information. Figure 5 , the method comprises the following steps:

[0079] S502: Update business object details from a business object database to a first local cache through a scheduled task.

[0080] The detailed information includes identification information of the business object. The identification information represents specific information that can uniquely identify each business object. The first local cache refers to a cache stored in the memory of the application server, which is used to store the business object detailed information. Specifically, the business object detailed information can be updated from the business object database to the first local cache at a predetermined time interval through an automatically programmed timer task.

[0081] S504: Sort the identification information of the business objects to obtain sorted identification information sorted according to a preset sorting method.

[0082] Among them, there are multiple preset sorting methods, and the business object has multiple attribute parameters. The preset sorting methods correspond to the attribute parameters of the business object one by one. For example, if the business object is a fund, the attribute parameters of the business object can be more than ten attribute parameters such as the unit net value of the fund, daily rise and fall, the past week, the past year, this year, and since its establishment. Similarly, by sorting the different attribute parameters of the business object, the identification information of different groups of business objects under the preset sorting methods corresponding to different attribute parameters can be obtained.

[0083] S506: Store the sorted identification information in the second local cache.

[0084] The first local cache is different from the second local cache. The second local cache may refer to a lightweight memory cache, which is also stored in the memory of the application server and is used to store sorted identification information of the business object. Specifically, after sorting the multiple attribute value data of the business object, multiple sorted local caches may be constructed, in which the sorted identification information of each attribute value data category of the business object is stored, and the sorted local cache may be regarded as the second local cache.

[0085] S508: Determine the number of pages and the current start mark.

[0086] The number of pages is the maximum number of business objects allowed to be displayed in the current page, and the current start identifier is used to indicate the sorting position of the first identifier used in the current query operation in the sorted identifier information. Specifically, the value of the number of pages can be a default value set by the system after balancing page loading time and user experience, and the current start identifier is determined by the number of pages, the order of traversing the sorted identifier information, and the current page number.

[0087] S510: If the sorted identification information is in ascending order, and the current starting identification is less than or equal to the number of business objects, the sorted identification information is traversed according to the number of pages and the current starting identification to obtain target identification information.

[0088] Specifically, after determining the number of pages and the current starting identifier, when the user issues an instruction to request a specific page number, the system will receive the number of pages and the current starting identifier passed by the calling service. At this time, the system will check whether the current starting identifier is greater than the number of all business objects stored in the first local cache. If so, it means that the requested page number exceeds the actual number of pages that can be displayed. At this time, the system returns an empty array, indicating that there is no more data to display; if not, it means that the requested page number can be displayed normally, then the sorted identifier information is traversed in ascending order to filter out all business objects that meet the conditions.

[0089] S512: If the sorted identification information is in descending order, and the current start identification is greater than zero, the sorted identification information is traversed according to the number of pages and the current start identification to obtain target identification information.

[0090] Specifically, after determining the number of pages and the current start identifier, when the user issues an instruction to request a specific page number, the system will receive the number of pages and the current start identifier passed by the calling service. At this time, the system will check whether the current start identifier is less than zero. If so, it means that the requested page number exceeds the actual number of pages that can be displayed. At this time, the system returns an empty array, indicating that there is no more data to display; if not, it means that the requested page number can be displayed normally, then the sorted identifier information is traversed in descending order to filter out all business objects that meet the conditions.

[0091] S514 traverses the sorted identification information according to the number of pages and the current starting identification to obtain target identification information.

[0092] Specifically, in the second local cache, the sorted identification information is traversed according to the number of pages and the current start identification, and the identification information of the business objects is retrieved one by one to obtain the target identification information.

[0093] S516: Obtain initial detail information corresponding to the target identification information from the first local cache.

[0094] The target details information refers to the details information of the business object stored in the first local cache. Specifically, the target details information is the details information of the business object obtained in the first local cache by a corresponding search method based on the target identification information obtained by traversing from the second local cache.

[0095] S518: Match the initial detailed information according to the screening conditions to obtain target detailed information that meets the screening conditions.

[0096] The target details are displayed on the current page. There may be more than one selection of filtering conditions. For example, if the business object is a fund, the filtering conditions may be fund type, risk level, years of establishment, fund size, etc. Specifically, the filtering process is to match and filter the initial details of the business object stored in the first local cache based on all selected filtering conditions, obtain the target details that meet the filtering conditions, and display them on the current page.

[0097] S520. Return target detailed information according to the target message structure.

[0098] The target message structure includes a value list and a key list. The value list includes the value of the key of the business object in the target detail information, and the key list includes the key of the business object in the target detail information. Specifically, the backend service will return a value list in a predetermined order according to the predefined field order convention. Since the keys of all business objects usually do not change in a process, it is only necessary to return the value list of the key of the target business object, that is, the key list, once each time the interface is called. After that, the product end can parse and use the data according to the predefined field order based on this key list.

[0099] It should be understood that, although the various steps in the above flowchart are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear description in this article, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a part of the steps in the above flowchart may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0109] In some embodiments, the target detail information is used to be displayed in the current page. Before traversing the sorted identification information to obtain the target identification information, the identification information traversal module 640 is also used to determine the number of pages and the current starting identification. The number of pages is the maximum number of business objects allowed to be displayed in the current page, and the current starting identification is used to indicate the sorting position of the first identification information used for the current query operation in the sorted identification information. Traversing the sorted identification information to obtain the target identification information includes: when the current starting identification does not exceed the range of the number of business objects, traversing the sorted identification information according to the number of pages and the current starting identification to obtain the target identification information.

[0110] In some embodiments, if the sorted identification information is arranged in ascending order, and the current starting identification does not exceed the range of the number of business objects, the sorted identification information is traversed according to the number of pages and the current starting identification to obtain the target identification information. The identification information traversal module 640 is also used to traverse the sorted identification information according to the number of pages and the current starting identification to obtain the target identification information when the current starting identification is less than or equal to the number of business objects.

[0111] In some embodiments, if the sorted identification information is arranged in descending order, and the current starting identification does not exceed the range of the number of business objects, the sorted identification information is traversed according to the number of pages and the current starting identification to obtain the target identification information. The identification information traversal module 640 is also used to traverse the sorted identification information according to the number of pages and the current starting identification to obtain the target identification information when the current starting identification is greater than zero.
