Description

Technical Field

[0001] This application relates to the field of Internet technologies, and in particular, to a data query method, apparatus, storage medium, and computer program product. Background Art

[0002] With the rapid development of human society, there are more and more exchange requirements between different types of digital resources. In order to ensure the accuracy and sensitivity of exchange rate prices, exchange rate quotation agencies for digital resource pairs (including two different types of digital resources) usually receive exchange rate updates from institutions such as banks at a frequency of hundreds of milliseconds, and then through technical components such as message systems and Remote Dictionary Server (Redis), process the exchange rate prices of banks within milliseconds to become the agency's own quotations to customers, that is, provide customers with exchange rate data query services. However, in order to pursue low latency of exchange rate prices, in the overall data link, once there is any service failure (such as Redis failure, network failure, etc.), the agency will not be able to provide quotation services to customers normally, resulting in the interruption of customers' data query services and poor continuity. Therefore, how to improve the continuity of data query services is an urgent problem to be solved. Summary of the Invention

It provides a network payment mode of a transaction payment platform that interfaces with the bank payment and settlement system by signing contracts with major banks. In the third-party payment mode, after the buyer selects the goods, the buyer uses the account provided by the third-party platform to pay the purchase price (pay to the third party), and the third party notifies the seller that the payment has arrived and requests the seller to ship the goods; after the buyer receives the goods, inspects the goods, and confirms, the buyer then notifies the third party to make the payment; the third party then transfers the funds to the seller's account.

[0045] The following introduces a data query system provided by an embodiment of the present application.

[0046] Please refer to Figure 1A , Figure 1A which is a schematic structural diagram of a data query system provided by an embodiment of the present application. As Figure 1AAs shown in the figure, the data query system includes a query server 101, a data processing server 102, a front-end server 103, a terminal device 104, a first database 105, and a second database 106. Among them, the query server 101 can communicate with the data processing server 102, the front-end server 103, the terminal device 104, the first database 105, and the second database 106 through the network for data communication. The data processing server 102 can communicate with the first database 105 and the second database 106 through the network for data communication. The query server 101, the data processing server 102, and the front-end server 103 may include cloud servers that provide basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The terminal device 104 may include a smart phone (such as an Android phone, an iOS phone, a Windows Phone), a desktop computer, a tablet computer, a handheld computer, a laptop computer, a mobile Internet device (MID), or a wearable device, etc. The first database 105 may include Redis, and the second database 106 may include Redis, MySQL, MongoDB, etc. The above communication methods, servers, terminal devices, and databases are only examples, not exhaustive, and include but are not limited to the above communication methods, servers, terminal devices, and databases.

[0047] In a feasible embodiment, the query server 101 receives a data query request sent by the terminal device 104. The query server 101 queries the first conversion parameter of the target digital resource pair from the first database 105 according to the identification information of the target digital resource pair in the data query request. When the acquisition of the first conversion parameter fails or the first conversion parameter is unavailable, the query server 101 queries the second conversion parameter of the target digital resource pair from the second database 106 and sends the second conversion parameter to the terminal device 104. Among them, the first conversion parameter of the target digital resource pair is written into the first database 105 in real time by the pre-server 103 through the data processing server 102; the second conversion parameter of the target digital resource pair is written into the second database 106 by the pre-server 103 at a first time interval. The first time interval for writing the target digital resource pair can be determined according to the update frequency of the target digital resource pair (the faster the update, the shorter the first time interval; conversely, the slower the update, the longer the first time interval), or it can be a fixed time interval (such as 10 seconds). In this embodiment, when the acquisition of the first conversion parameter fails or the first conversion parameter is unavailable, the query server 101 can query the second conversion parameter of the target digital resource pair from the second database 106 and send the second conversion parameter to the terminal device 104, effectively improving the continuity of the query service and the customer experience.

[0048] In a feasible embodiment, as Figure 1B shown, in Figure 1ABased on the data query system shown, the data query system further includes a data source server 107 and a message component 108. The query server 101 further includes a downgraded query switch 1011. Among them, the message component 108 may include a message queue for enqueuing the latest conversion parameters of the target digital resource pair, so that the data processing server 102 can obtain the latest conversion parameters of the target digital resource pair from it; after receiving the conversion parameters of the target digital resource pair sent by the query server 101, the terminal device 104 can output the conversion parameters of the target digital resource pair, so that the user can timely know the conversion parameters of the target digital resource pair. The output method can be displayed on the terminal device 104 with sound or vibration prompts, or it can be in the form of voice broadcast; the data source server 107 may include a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms; the downgraded query switch 1011 is controlled by the query server 101, and the data source server 107 uses the FIX protocol (streaming exchange rate) to communicate with the front-end server 103 through the network. The data source server 107 may be a server of a financial institution such as a bank, and is used to push the latest conversion parameters of each digital resource pair to the front-end server 103. The above servers and communication methods are only examples, not exhaustive, and include but are not limited to the above servers and communication methods.

[0049] Among them, when the first conversion parameter acquisition fails or the first conversion parameter is unavailable, the query server 101 turns on the downgraded query switch 1011; when the downgraded query switch 1011 is turned on, the query server 101 can query the first conversion parameter from the first database 105 at a second time interval, obtain a query result, and determine the query success rate according to the query result. When the query success rate is greater than or equal to the preset success rate threshold, the downgraded query switch is turned off.

[0050] In a feasible embodiment, when the query server 101 receives a data query request from the terminal device 104 and determines that the downgraded query switch 1011 is turned on, it can query the second conversion parameter of the target digital resource pair in the data query request from the second database 106, obtain the adjustment amount of the conversion parameter of the target digital resource pair, determine the third conversion parameter according to the second conversion parameter and the adjustment amount of the conversion parameter, and send the third conversion parameter to the terminal device 104 so that the user knows the conversion parameter of the current target digital resource pair. Among them, the adjustment amount of the conversion parameter can be determined according to the historical conversion parameter or can be preset by relevant staff. In this embodiment, the query server 101 determines the third conversion parameter according to the second conversion parameter and the adjustment amount of the conversion parameter, which can effectively reduce the losses of the conversion parameter supplier.

[0051] The following introduces a data query method provided by an embodiment of the present application.

[0052] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a data query method provided by an embodiment of the present application. The data query method provided by an embodiment of the present application can be applied to the data query system shown above Figure 1A For example, the data query method is described below by taking the query server in the data query system as an example.

[0053] As Figure 2 shown, the data query method includes:

[0054] S201. The query server receives a data query request sent by the terminal device, and the data query request includes identification information of a target digital resource pair.

[0055] In an embodiment of the present application, the terminal device may send a data query request including identification information of a target digital resource pair to the query server. After receiving the data query request, the query server can query the conversion parameter of the target digital resource pair according to the identification information of the target digital resource pair.

[0056] In a feasible embodiment, the conversion parameter may be an exchange ratio (also referred to as an exchange rate) between two digital resources in the target digital resource pair.

[0057] S202. The query server queries the first conversion parameter of the target digital resource pair from the first database according to the identification information of the target digital resource pair, and the first conversion parameter of the target digital resource pair is written into the first database in real time by the preposed server through the data processing server.

[0058] In the embodiment of the present application, the query server may query the first conversion parameter of the target digital resource pair from the first database according to the identification information of the target digital resource pair. The first conversion parameter of the target digital resource pair is written into the first database in real time by the front-end server through the data processing server.

[0059] In a feasible embodiment, the first conversion parameter may be a more time-sensitive transaction exchange rate between the two digital resources in the target digital resource pair.

[0060] S203. When the acquisition of the first conversion parameter fails or the first conversion parameter is unavailable, the query server queries the second conversion parameter of the target digital resource pair from the second database according to the identification information of the target digital resource pair. The second conversion parameter of the target digital resource pair is written into the second database by the front-end server at a first time interval.

[0061] In the embodiment of the present application, when the acquisition of the first conversion parameter fails or the first conversion parameter is unavailable, the query server may query the second conversion parameter of the target digital resource pair from the second database according to the identification information of the target digital resource pair. The failure to obtain the first conversion parameter may mean that the first conversion parameter cannot be obtained from the first database (there is no first conversion parameter in the first database), or the first database has no response (for example, it cannot be obtained due to network reasons or the first database fails); the unavailability of the first conversion parameter may include that the first conversion parameter in the first database has not been updated for a long time, which may be caused by a failure of the front-end server or the data processing server; the second conversion parameter is written into the second database by the front-end server at a first time interval.

[0062] In a feasible embodiment, the second conversion parameter may be a reference exchange rate between the two digital resources in the target digital resource pair.

[0063] In a feasible embodiment, the query server obtains the target time corresponding to the first conversion parameter of the target digital resource pair. The target time includes the generation time of the first conversion parameter or the time when the first conversion parameter is written into the first database; if the time interval between the target time and the current time is greater than or equal to the first duration, the query server determines that the first conversion parameter is unavailable.

[0064] Specifically, after the query server obtains the first conversion parameter of the target digital resource pair, it can determine the time interval between the target time corresponding to the first conversion parameter and the current time according to the target time corresponding to the first conversion parameter. If the time interval is greater than or equal to the first duration, it is determined that the first conversion parameter is unavailable. The target time corresponding to the first conversion parameter can be the generation time of the first conversion parameter (the time sent by the data source server to the query server or the time when the data source server generates the first conversion parameter), or the time when the first conversion parameter is written into the first database; the first duration for each digital resource pair can be determined according to the update frequency of each digital resource pair; it can also be a fixed time (such as 10 seconds).

[0065] In a feasible embodiment, the target digital resource pair may include a first digital resource and a second digital resource, the first digital resource pair may include a first digital resource and a third digital resource, and the second digital resource pair may include a third digital resource and a second digital resource; the first conversion parameter of the target digital resource pair may be the exchange rate between the first digital resource and the second digital resource, the conversion parameter of the first digital resource pair may be the exchange rate between the first digital resource and the third digital resource, and the conversion parameter of the second digital resource pair may be the exchange rate between the third digital resource and the second digital resource; when the query server determines that the acquisition of the first conversion parameter fails or the first conversion parameter is unavailable, it can query the conversion parameter of the first digital resource and the conversion parameter of the second digital resource in the first database, and use the conversion parameter of the first digital resource and the conversion parameter of the second digital resource to determine the first conversion parameter of the target digital resource pair. In this embodiment, when the conversion parameter of the target digital resource pair is unavailable and the conversion parameters of the first digital resource pair and the second digital resource pair are available, the conversion parameter of the target digital resource pair can be directly determined by using the conversion parameters of the first digital resource pair and the second digital resource pair and provided to the user.

[0066] In a feasible embodiment, when the query server determines that the acquisition of the first conversion parameter fails or the first conversion parameter is unavailable, it can send a query instruction for the current conversion parameter of the target digital resource pair to the front-end server. After receiving the query instruction for the current conversion parameter of the target digital resource pair, the front-end server sends a query request for the current conversion parameter of the target digital resource pair to the data source server. The data source server sends the current conversion parameter of the target digital resource pair to the front-end server, and the front-end server sends the current conversion parameter of the target digital resource pair to the query server, so that the latest conversion parameter can be directly obtained in a timely manner through the front-end server and provided to the user.

[0067] S204. The query server sends the second conversion parameter to the terminal device.

[0068] In the embodiments of the present application, after the query server queries the second conversion parameter, it may send the second conversion parameter to the terminal device. When the first conversion parameter in the first database is unavailable, the user can also receive the second conversion parameter of the second database, effectively improving the continuity of the query service and the user experience.

[0069] In a feasible embodiment, the query server sending the second conversion parameter to the terminal device includes: the query server obtaining the conversion parameter adjustment amount of the target digital resource pair; the query server determining a third conversion parameter of the target digital resource pair according to the conversion parameter adjustment amount and the second conversion parameter; and the query server sending the third conversion parameter to the terminal device.

[0070] Specifically, after the query server queries the second conversion parameter from the second database, it can obtain the conversion parameter adjustment amount corresponding to the second conversion parameter (i.e., the conversion parameter adjustment amount of the target digital resource pair), then calculate the third conversion parameter according to the second conversion parameter and the conversion parameter adjustment amount corresponding to the second conversion parameter, and send the third conversion parameter to the terminal device. Among them, the target digital resource pair may include a first digital resource and a second digital resource, and the second conversion parameter may be the exchange rate of the first digital resource and the second digital resource with poor timeliness. Taking the query server as a third-party payment as an example, assuming that the second conversion parameter is 7.2 and the conversion parameter adjustment amount is 0.3, the calculation process of the third conversion parameter formula is 7.2*(1 + 0.03)=7.416, and the third conversion parameter can be obtained as 7.416. The conversion parameter of the target digital resource pair of 7.416 can be sent to the terminal device. In this embodiment, the third conversion parameter can be determined by using the second conversion parameter and its corresponding conversion parameter adjustment amount, and sending the larger third conversion parameter to the terminal device can effectively reduce the risk of third-party payment.

[0071] In a feasible embodiment, the query server obtains the fluctuation data of the conversion parameter of the target digital resource pair within a preset time period; the query server determines the fluctuation level of the conversion parameter of the target digital resource pair according to the fluctuation data; and the query server determines the conversion parameter adjustment amount of the target digital resource pair according to the fluctuation level.

[0072] Specifically, the query server can obtain the fluctuation data of the conversion parameters of the target digital resource pair within a preset time period, determine the fluctuation level of the conversion parameters of the target digital resource pair according to the fluctuation data, and determine the adjustment amount of the conversion parameters of the target digital resource pair according to the fluctuation level. Among them, the fluctuation level of the conversion parameters of the target digital resource pair can be determined according to the fluctuation degree of the conversion parameters of the target digital resource pair, and the greater the fluctuation degree, the higher the fluctuation level; when the fluctuation level of the conversion parameters of the target digital resource pair is relatively high, the adjustment amount of the conversion parameters of the target digital resource pair can be set relatively high. For example, the fluctuation levels are level 1, level 2, and level 3 respectively. When the fluctuation level is level 1, the adjustment amount of the conversion parameters is determined to be 0.1; when the fluctuation level is level 2, the adjustment amount of the conversion parameters is determined to be 0.2; when the fluctuation level is level 3, the adjustment amount of the conversion parameters is determined to be 0.3. In this embodiment, determining the adjustment amount of the conversion parameters of the target digital resource pair according to the fluctuation data of the conversion parameters of the target digital resource pair can effectively improve the accuracy of the third conversion parameter adjusted by the adjustment amount of the conversion parameters.

[0073] In a feasible embodiment, the query server obtains the switch state of the downgraded query switch; if the switch state indicates that the downgraded query switch is closed, the query server executes the step of querying the first conversion parameter of the target digital resource pair from the first database according to the identification information of the target digital resource pair; if the switch state indicates that the downgraded query switch is open, the query server queries the second conversion parameter of the target digital resource pair from the second database according to the identification information of the target digital resource pair.

[0074] Specifically, after receiving the data query request for querying the target digital resource pair, the query server can obtain the switch state of the downgraded query switch of the target digital resource pair. When the downgraded query switch is closed, the query server queries the first conversion parameter of the target digital resource pair from the first database according to the identification information of the target digital resource pair; when the downgraded query switch is open, the query server queries the second conversion parameter of the target digital resource pair from the second database according to the identification information of the target digital resource pair. Among them, one downgraded query switch can correspond to one or more digital resource pairs. In this embodiment, the query server can determine whether to query the conversion parameter of the target digital resource pair from the first database or the second database according to the switch state of the downgraded query switch of the target digital resource pair, effectively improving the acquisition efficiency of the conversion parameter of the target digital resource pair.
