[0002] There are many ways to exchange data between systems, and calling interfaces is the most common method on the internet today. This method allows for fast and efficient data exchange. However, communication between clients and servers via interfaces is often synchronous.

[0003] Currently, feedback from the server is usually used to determine whether the data between the client and the server is synchronized, and a retry mechanism with a set number or time is used to resolve interaction failures to achieve data consistency. However, these mechanisms are not constrained by the client's business logic and are therefore difficult to meet the client's needs. Summary of the Invention

[0043] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0044] Example 1

[0045] This embodiment provides a data synchronization method, which is applied to a client. Figure 1 As shown, the data synchronization method includes:

[0046] S1. When initiating a service request to a server, first start a delay message and then send the service request to the server; wherein the delay message is used to start a message queue containing information about the service request after a specific delay; S2. After the message queue is started, query the service status of the service request according to the message queue;

[0047] S3. Determine whether the data with the server is synchronized based on the business status;

[0048] S4. If it is determined that the data with the server is not synchronized, a corresponding synchronization operation is performed; wherein the synchronization operation is used to achieve data synchronization.

[0049] In practice, service requests can include deductions, refunds, advances, completions, merchant number changes, and more. When a client initiates a service request to a server, it must first initiate a delay message before sending the specific service request to the server. Specifically, the delay message is a message queue containing the specific service request information, which is then processed by the client after a specific delay.

[0050] In this embodiment, taking a deduction request as an example, when the client initiates a deduction request to the server, it first starts a delay message and then sends the deduction request to the server; after a specific delay, the client starts processing the message queue including the deduction request, and queries the business status of the deduction request on the client according to the message queue; determines whether the deduction data with the server is synchronized according to the business status; if the client determines that the deduction data with the server is not synchronized, it performs the corresponding synchronization operation.

[0051] In one feasible solution, Figure 2 As shown, step S3 specifically includes:

[0052] (1) If the service state is the initialization state, it is determined that the data is not synchronized with the server;

[0053] (2) If the service state is the waiting state, it is determined that the data is not synchronized with the server.

[0054] In the embodiment, taking the deduction service as an example, the interaction between the client and the server includes:

[0055] (1) The client initiates a deduction request: first, a delay message is started, and then a deduction request is sent to the payment center of the server;

[0056] (2) The server returns the refund result to the client through asynchronous callback. If the service state of the refund service is the initialization state, the client fails to send the refund request to the server, that is, the data is not synchronized;

[0057] If the service state of the refund service is the waiting state, the client successfully sends the refund request to the payment center of the server, and does not receive the refund result of the server, that is, the data is not synchronized.

[0058] In the specific implementation, after the client starts the message queue, the service state of the deduction service is queried according to the specific information of the deduction service contained in the message queue.

[0059] Specifically, the client can view the interface state of data transmission with the server according to the business name of the deduction service, so as to obtain the service state of the deduction service.

[0060] Specifically, the client can also query the data state of the deduction service in the database. If the flag data is the initialization state, the service state is the initialization state; if the flag data is the waiting state, the service state is the waiting state.

[0061] In the specific implementation, the service request includes a service execution request and a service query request;

[0062] In an implementable scheme, as shown in FIG. 4, step S4 specifically includes: Figure 2

[0063] (1) If the service state is the initialization state, a service execution request is sent to the server;

[0064] (2) If the service state is the waiting state, a service query request is sent to the server; wherein the service query request is used to query the process of the service execution request in the server.

[0065] In an implementable scheme, the data synchronization method further includes:

[0066] ​S5. Receive a response signal from the server; wherein the response signal includes a signal from the server responding to the service request;

[0067] S6. Determine, based on the response signal, whether to send the message queue again according to a preset rule corresponding to the service request; wherein the preset rule includes a preset interval time for sending the message queue.

[0068] In specific implementations, different business requests correspond to different preset rules to meet the needs of different business requests.

[0069] In a specific implementation, the message queue includes setting a tag.

[0070] In this embodiment, the client adds a set tag to the message queue. The set tag is a unique key for the client to access the server, which can be used as an idempotent checker and also as the main query condition of the polling mechanism.

[0071] In one feasible solution, step S6 includes:

[0072] (1) If the response signal includes a set tag, synchronizing the data of the service request according to the response signal and terminating the sending message queue;

[0073] (2) If the response signal does not include the set tag, the message queue is sent again according to the preset rules.

[0074] In this embodiment, the client sends a message queue with a set tag to the server. When a response signal with the set tag is received, it indicates that the last interaction between the client and the server was successful. The client synchronizes the data of the business request according to the information in the response signal and stops sending the message queue to the server. When the response signal does not carry a set tag, it indicates that the data synchronization between the client and the server still fails, and the message queue is sent again according to the preset rules.

[0075] In this embodiment, if the preset rule of the deduction request is every 2 n-1 The system requests once every minute (n is the number of data retries), and first receives the response signal from the server. If the response signal does not carry the set tag, the data has not been recovered, so the first data retry is performed, and the message queue is sent and the response signal is received every 1 minute. If the response signal still does not carry the set tag, the second data retry is performed, and the message queue is sent every 2 minutes... Continue to retry data according to the preset rules until a response signal with a set tag is received. The data is recovered, the business status is updated according to the information of the response signal with the set tag, and the data retry is terminated.

[0076] In one feasible solution, the data synchronization method further includes:

[0077] S7, when the total number of times of sending the message queue reaches a number threshold or the total time reaches a time threshold, terminating sending the message queue; wherein the number threshold or the time threshold is a preset threshold of the client.

[0078] In an implementable solution, step S7 is followed by further comprising:

[0079] S8, sending the message queue to a database for subsequent processing.

[0080] In a specific implementation, when the total number of times of sending the message queue exceeds a maximum number threshold preset by the client or the total time exceeds a maximum time threshold preset by the client, it is considered that the data retry fails, and the message queue is persisted to the database for manual or Job processing.

[0081] The application initiates a business request to the server, first starts a delay message, and then sends the business request to the server. When the delay time is reached, the client can actively query and determine whether the data of the server is synchronized according to the message queue, and perform corresponding synchronization operations according to the business state. It can not only handle the data asynchronization caused by long time interval communication exception without human intervention, but also can perform different synchronization operations according to different business states to achieve data consistency, so as to more effectively meet the needs of the client and improve the stability and practicability of data transmission between systems.
