Description

Response timeout processing method, server and client response timeout processing system

Technical field

The invention relates to the technical field of computer applications, and in particular to a response timeout processing method, a server and a client response timeout processing system.

Background technique

In a client-server system, the client depends on the server to provide the required services. When the system interacts normally, as shown in Figure 2, the client sends request A to the server. The server responds immediately after receiving request A and processes it. The result is returned to the client, but in the actual application scenario, when the system is affected by factors such as network delays or network interruptions, the server may delay receiving or not receiving request A, and the corresponding server will delay correspondingly or not respond. At the time, because the client did not receive the server's receipt of the processing result within the preset time, the client will start the fuse mechanism itself, prompting the user to time out abnormally, and at the same time perform a rollback operation for request A in time, so that the user can Request A to initiate a retry and complete the operation.

In the prior art, when a time-out abnormal event occurs, the server generally adopts a manual elimination or automatic rollback mechanism to deal with the abnormality. Because manual elimination takes a long time and has poor accuracy, which affects the user's experience, it is not suitable for large-scale promotion For the automatic rollback mechanism, although it has the characteristics of high efficiency and timeliness, the server cannot monitor and identify the processing result, that is, it cannot determine whether the processing result is being processed or completed. Because the processing result being processed cannot be rolled back, if the server Rolling it back will cause the system to report an error.

Summary of the invention

The object of the present invention is to provide a response timeout processing method, a server and a client response timeout processing system, which can promptly, efficiently and accurately start a rollback mechanism to handle exceptions and improve user experience.

In order to achieve the above object, one aspect of the present invention provides a response timeout processing method, including:

Step S1, the server receives the service request sent by the client, and at the same time sets a progress identification character in the process of processing the service request;

Step S2, the server feeds back the request receipt to the client, and when the request receipt is a response timeout, it determines whether the current service request is completed by querying the progress identifier character;

Step S3, if the current service request processing is completed, perform a rollback operation on the service request, and if the current service request processing is not completed, change the progress identification character;

Step S4, after the execution of the processing process of the business request is completed, check whether the progress identification character has changed, when the check result is yes, perform a rollback operation on the business request, and delete the progress identification character at the same time, when the check result Otherwise, directly delete the progress identification character;

Step S5, return to step S1, and send the service request to the server again through the client until the request receipt response in step S2 does not time out.

Preferably, in step S1, the method for setting the progress identification character in the process of processing the service request is:

In the process of business request processing, the progress identification character is set by the setnx method in the redis cache.

Preferably, in step S2, the server feeds back the request receipt to the client, and when the request receipt is the response timeout, the method for determining whether the current service request is completed by querying the progress identification character includes:

Based on the identification number of the current business request, the server queries the progress identification characters in the current business request processing process;

If the current processing process is not ended and the query result exists, the output of the current business request processing is not completed, otherwise the output of the current business request processing is completed.

Optionally, the progress identification character is a status value.

Optionally, the business request is a non-idempotent service request.

Exemplarily, the identification number of the business request is a business serial number or a business order number.

Compared with the prior art, the response timeout processing method provided by the present invention has the following beneficial effects:

In the response timeout processing method provided by the present invention, after receiving the service request sent by the client, the server first sets a progress identification character in the process of processing the business request, so as to determine the current business request by identifying the progress identification character in subsequent procedures Whether the processing is completed, the specific process is as follows, when the client does not receive the request receipt returned by the server within the preset time, it is considered that the request receipt response times out, at this time, the client will report an error to the user and automatically send the calling instruction to the server, Enables the server to query the progress identification characters previously set in the business request according to the calling instruction, and determine whether the current business request is completed based on the progress identification characters. If the judgment result is that the current business request processing is completed, you can directly complete the completed business Request to perform a rollback operation. If the current business request processing is not completed, the business request will not be rolled back temporarily, and only the above progress identification character will be changed until the completion of the above business request processing process, by checking the progress identification character whether Changed, when the result is yes, it means that the business request has not been rolled back before, at this time, only the business request needs to be rolled back, and the progress identification character is deleted, when the result is no, then It means that the business request has previously performed a rollback operation. In this case, you only need to delete the progress identifier character without repeating the rollback operation on the business request. Finally, the user sends the business request to the server again through the client to perform the above operation Until the user's request receipt response has not timed out.

It can be seen that the present invention sets the progress identification character in the processing process of the business request, and judges the processing progress of the current business request based on the progress identification character, so as to realize that the server can automatically perform the rollback operation when the current business request processing is completed. When the business request is not processed, in order to avoid the system reporting an error, the current business request will not be rolled back, and only measures to change the progress identification character will be taken to make it selective according to the change of the progress identification character after the processing process is executed. The rollback operation is performed on business requests that have not performed a rollback operation, thereby effectively avoiding the system error caused by the rollback operation performed before the end of the processing process, and ensuring the accurate timing of the rollback operation. And the stability of the system; in addition, compared with the processing mechanism for manually solving the response timeout in the prior art, adopting the timeout processing method provided by the invention also has the characteristics of being fast and efficient.

The server execution unit is configured to perform a rollback operation on the business request if the current business request processing is completed according to the judgment result, and change the progress identification character if the current business request processing is not completed;

The server checking unit is used to check whether the progress identification character has changed after the execution of the processing process of the business request is completed, and when the check result is yes, perform a rollback operation on the business request and delete the progress identification character, When the check result is otherwise, directly delete the progress identification character;

The server retry unit is used to re-send a service request to the server through the client.

Preferably, the server judgment unit includes:

The server query module is used to query the progress identification characters in the current business request processing process through the server based on the identification number of the current business request;

The server judgment module is used to output that the current business request processing is not completed if the current processing process is not completed and the query result exists, otherwise it is output that the current business request processing is completed.

Example one

FIG. 1 is a method for processing a response timeout in Embodiment 1 of the present invention. Referring to FIG. 1, this embodiment provides a response timeout processing method, including:

Step S1, the server receives the business request sent by the client, and at the same time sets the progress identification character in the process of processing the business request; step S2, the server feeds back the request receipt to the client, and queries the progress identification character when the request receipt is the response timeout Determine whether the current business request is completed; Step S3, if the current business request processing is completed, perform a rollback operation on the business request, if the current business request processing is not completed, then change the progress identifier; Step S4, in the business request processing process After the execution is completed, check whether the progress indicator character has changed. When the check result is yes, perform a rollback operation on the business request and delete the progress indicator character. When the check result is otherwise, delete the progress indicator character directly; Step S5, return to step S1 The client sends the service request to the server again until the request receipt response in step S2 does not time out.

In the response timeout processing method provided by this embodiment, after receiving the service request sent by the client, the server first sets a progress identification character in the process of processing the business request, so as to determine the current service by identifying the progress identification character in subsequent procedures Whether the request is processed, the specific process is as follows. When the client does not receive the request receipt returned by the server within a preset time, it is considered that the request receipt response timed out. At this time, the client will report an error to the user and automatically send a call instruction to the server , So that the server can query the progress identification character previously set in the business request according to the calling instruction, and judge whether the current business request is completed based on the progress identification character. If the judgment result is that the current business request processing is completed, you can directly check the completed Perform a rollback operation on the business request. If the current business request processing is not completed, the business request will not be rolled back temporarily, and only the above progress identification character will be changed until the completion of the above business request processing process is completed. Character is No change, when the result is yes, it means that the business request has not previously performed a rollback operation. At this time, it is only necessary to perform a rollback operation on the business request, and delete the progress identification character. When the result is no, It means that the business request has previously performed a rollback operation. At this time, it is only necessary to delete the progress identification character without repeatedly performing the rollback operation on the business request. Finally, the user sends the business request to the server through the client again Operate until the user's request receipt response has not timed out.

It can be seen that in this embodiment, by setting a progress identification character in the processing process of the business request and judging the processing progress of the current business request based on the progress identification character, the server can automatically perform a rollback operation when the current business request processing is completed, and When the current business request has not been processed, in order to avoid the system reporting an error, the current business request will not be rolled back first, and only the measure of changing the progress identification character will be taken, so that it will be selected according to the change verification result of the progress identification character after the processing process is completed. Perform a rollback operation on business requests that have not performed a rollback operation, thus effectively avoiding the system error caused by the rollback operation performed before the end of the processing process, and ensuring the start time of the rollback operation Accuracy and stability of the system; in addition, compared with the processing mechanism for manually solving the response timeout in the prior art, the response timeout processing method provided by this embodiment also has the characteristics of being fast and efficient.

It can be understood that the business request in the foregoing embodiment refers to a non-idempotent service request. In order to enable those skilled in the art to better understand the response timeout processing method, this embodiment uses the order lock coupon as an example to describe the following:

When the user selects a good product in the shopping cart, he can simultaneously select the appropriate coupon to submit the order. At this time, after receiving the business request submitted by the order, the server will immediately process the business request and feedback the request receipt to the client. , The business request processing includes calling the merchandise inventory resources and promotional preferential resources to lock the selected merchandise and the selected coupon, respectively, but when the client receives a response to the request receipt, the user is not clear whether the server has already selected the merchandise and If the selected coupon is locked, if you insist on performing a rollback operation if the above locking operation is not completed, it will lead to instability of the server, and in order to ensure the user's shopping experience, you cannot unilaterally ensure The above lock operation is completed and the server is left with too much execution time. This method of responding to timeout processing by sacrificing user waiting time will reduce the user's shopping experience, which is obviously unreasonable. Therefore, how to perform the rollback operation as soon as possible after the lock operation is completed has become the key problem to be solved in this embodiment. In this embodiment, the progress identification character is set in the lock operation process, and the processing progress of the current lock operation is judged based on the progress identification character. To realize that the server can automatically perform the rollback operation when the current lock operation processing is completed, and when the current lock operation is not completed, in order to avoid the system reporting an error, the rollback operation is not performed on the current lock operation, and only measures to change the progress identification character are taken After the execution of the lock operation is completed, it selectively rolls back the lock operation that has not performed the rollback operation according to the change verification result of the progress identification character, thereby effectively avoiding the lock operation from being executed before the end of the processing process. The system error caused by the roll operation.

Exemplarily, in step S1 of the foregoing embodiment, the method for setting the progress identification character in the service request processing process is: in the service request processing process, the progress identification character is set by the setnx method in the redis cache. Optionally, the above progress identification character is a status value.

Further, in step S2 of the foregoing embodiment, the server feeds back the request receipt to the client, and when the request receipt is the response timeout, the method for determining whether the current service request is completed by querying the progress identification character includes:

Based on the identification number of the current business request, the server queries the progress identification characters in the current business request processing process; if the current processing process is not ended and the query result exists, it outputs the current business request processing is not completed, otherwise it outputs the current business request processing is completed. Exemplarily, the identification number of the business request is a business serial number or a business order number.
