SERVER AND CLIENT TO PROCESS RESPONSE TIMEOUT
BACKGROUND OF THE INVENTION
Technical Field [0001] The present invention relates to the technical field of computer applications, and more particularly to a method for processing response timeout, and a system for a server and a client to process response timeout.
Description of Related Art
[0002] In a client-server system, a server provides clients with services they need. During normal interaction, as shown in FIG. 2, a client sends a request A to the server.
After receiving the request A, the server immediately responds and sends the processing result back to the client. However, in practical application scenarios, due to network delay or network interruption, the server may receive the request A at a later time or even not receive it eventually. In this case, the corresponding server will respond at a later time or even not respond at all. If the client has not received the processing result from the server in a predetermined time frame, the client will automatically trigger a fuse mechanism and inform the user of the timeout anomaly. The client also performs a rollback operation on the request A timely, so as to prompt the user to initiate a retry for the request A through the client, thereby finishing the process.

However, in practical application scenarios, due to network delay or network interruption, the server may receive the request A at a later time or even not receive it eventually. In this case, the corresponding server will respond at a later time or even not respond at all.

The client also performs a rollback operation on the request A timely, so as to prompt the user to initiate a retry for the request A through the client, thereby finishing the process.
[0003] In the prior art, a server typically processes a timeout anomaly happens by means of manual removal or an automatic rollback mechanism. However, manual removal of anomalies is relatively time-consuming and inaccurate, making it unfavorable to good user experience and thus limited in deployment. As to the automatic rollback mechanism, while it features high efficiency and timeliness, the server is unable to monitor the processing result. In other words, it will be a problem to determine whether the request is Date Recue/Date Received 2022-04-21 under processing or has been processed. Since the rollback operation should not be performed on a request under processing, an improperly conducted rollback operation can lead to system errors.
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[0004] The objective of the present invention is to provide a method for processing response timeout, and a system for a server and a client to process response timeout, which activate a rollback mechanism timely, efficiently, and accurately to deal with anomalies, thereby providing improved user experience.
[0005] To achieve the foregoing objective, in a first aspect, the present invention provides a method for processing response timeout, comprising the following steps:
[0006] 51: having a server receive a service request from a client, and set a progress-indicating character during a process of processing the service request;
[0007] S2: having the server feed a request acknowledgement back to the client, and when a response timeout occurs with respect to the request acknowledgement, determine whether the current service request has been processed by means of retrieving the progress-indicating character;
[0008] S3: if the process of processing the current service request has been done, performing a rollback operation on the service request, or if the process of processing the current service request has not been done, changing the progress-indicating character;
[0009] S4: after the process of processing the service request has been done, checking whether the progress-indicating character has changed, and if yes, performing a rollback operation on the service request, and also deleting the progress-indicating character, or if not, just deleting the progress-indicating character; and
[0010] S5: returning to 51, and having the client resend the service request to the server, until a response timeout no longer occurs with respect to the request acknowledgement of S2.
[0011] Preferably, at 51, the step of setting a progress-indicating character during a process of processing the service request comprises:
Date Recue/Date Received 2022-04-21
Date Recue/Date Received 2022-04-21
[0012] during the process of processing the service request, setting progress-indicating character using a setnx method stored in a redis cache.
[0013] Preferably, at S2, the step of having the server feed a request acknowledgement back to the client, and when a response timeout occurs with respect to the request acknowledgement, determine whether the current service request has been processed by means of retrieving the progress-indicating character comprises:
[0014] having the server, based on an identification number of the current service request, retrieve the progress-indicating character in the process of processing the current service request; and
[0015] if the current process has not ended and the progress-indicating character is retrieved, giving an output indicating that the process of processing the current service request has not been done, or, otherwise, giving an output indicating the process of processing the current service request is done.
[0016] Optionally, the progress-indicating character is a state value.
[0017] Optionally, the service request is a request for a non-idempotent service.
[0018] Exemplarily, the identification number of the service request is a service serial number or a service order number.
[0019] As compared to the prior art, the method for processing response timeout of the present invention provides the following beneficial effects:
[0020] In the method for processing response timeout of the present invention, after receiving a request from the client, the server first sets a progress-indicating character in the process of processing the service request. The progress-indicating character is used to determine whether the process of processing the current service request is done.
Specifically, if the client does not receive acknowledgement about the request within a predetermined timeframe, it is determined that the response of the server to the request is timeout. At this time, the client reports an error to the user and automatically sends a call instruction to the server, so that the server can retrieve the progress-indicating character set in the service request previously according to the call instruction, and then determine whether the process of processing the current service request is done based on the progress-Date Recue/Date Received 2022-04-21 indicating character. If the result is that the process of processing the current service request is done, a rollback operation is directly executed for the processed service request.
If the process of processing the current service request has not been done, instead of performing a rollback operation for the service request, the server only changes the progress-indicating character until the process of processing the service request has been done. In checking whether the progress-indicating character has been changed, if the result is yes, it indicates that the service request has never received a rollback operation.
Thus, the method is proceeded with performing a rollback operation on the service request and deleting the progress-indicating character. When the result is no, it indicates that the service request has received a rollback operation. The method now is proceeded with only deleting the progress-indicating character without performing a rollback operation on the service request. At last, the user resends the service request to the server through the client to perform the foregoing operation until the request acknowledgement is sent to the user before response timeout.
Specifically, if the client does not receive acknowledgement about the request within a predetermined timeframe, it is determined that the response of the server to the request is timeout. At this time, the client reports an error to the user and automatically sends a call instruction to the server, so that the server can retrieve the progress-indicating character set in the service request previously according to the call instruction, and then determine whether the process of processing the current service request is done based on the progress-Date Recue/Date Received 2022-04-21 indicating character. If the result is that the process of processing the current service request is done, a rollback operation is directly executed for the processed service request.
If the process of processing the current service request has not been done, instead of performing a rollback operation for the service request, the server only changes the progress-indicating character until the process of processing the service request has been done. In checking whether the progress-indicating character has been changed, if the result is yes, it indicates that the service request has never received a rollback operation.
Thus, the method is proceeded with performing a rollback operation on the service request and deleting the progress-indicating character. When the result is no, it indicates that the service request has received a rollback operation. The method now is proceeded with only deleting the progress-indicating character without performing a rollback operation on the service request. At last, the user resends the service request to the server through the client to perform the foregoing operation until the request acknowledgement is sent to the user before response timeout.
[0021] It is thus clear that the present invention uses a progress-indicating character set in the process of processing a service request as a basis for determining the processing progress of the current service request, so that when the process of processing the current service request is done, the server can automatically perform a rollback operation, and when if the process of processing the current service request has not been done, for avoiding system errors, the rollback operation is held, and only the progress-indicating character is changed at this moment, so that after the processing process is done, a rollback operation can be selectively performed on the service request that has not received a rollback operation according to the checking result of whether the progress-indicating character has been changed. This can effectively avoid the defect of system errors caused by improperly executing a rollback operation before the process of processing the service request has been done, thereby ensuring of good timing of activation of a rollback operation and stability of the system. In addition, as compared to the prior-art approach that deals with response timeout manually, the timeout processing method of the present invention is faster and more efficient.

[0051] In the method for processing response timeout of the present invention, after receiving a request from the client, the server first sets a progress-indicating character in the process of processing the service request. The progress-indicating character is used to determine whether the process of processing the current service request is done.
Specifically, if the client does not receive acknowledgement about the request within a predetermined timeframe, it is determined that the response of the server to the request is timeout. At this time, the client reports an error to the user and automatically sends a call instruction to the server, so that the server can retrieve the progress-indicating character set in the service request previously according to the call instruction, and then determine whether the process of processing the current service request is done based on the progress-indicating character. If the result is that the process of processing the current service request is done, a rollback operation is directly executed for the processed service request.
If the process of processing the current service request has not been done, instead of performing a rollback operation for the service request, the server only changes the progress-indicating character until the process of processing the service request has been done. In checking whether the progress-indicating character has been changed, if the result is yes, it indicates that the service request has never received a rollback operation.
Thus, the method is proceeded with performing a rollback operation on the service request and deleting the progress-indicating character. When the result is no, it indicates that the service request has received a rollback operation. The method now is proceeded with only deleting the progress-indicating character without performing a rollback operation on the service request. At last, the user resends the service request to the server through the client to perform the foregoing operation until the request acknowledgement is sent to the user before response timeout.
Specifically, if the client does not receive acknowledgement about the request within a predetermined timeframe, it is determined that the response of the server to the request is timeout. At this time, the client reports an error to the user and automatically sends a call instruction to the server, so that the server can retrieve the progress-indicating character set in the service request previously according to the call instruction, and then determine whether the process of processing the current service request is done based on the progress-indicating character.

The method now is proceeded with only deleting the progress-indicating character without performing a rollback operation on the service request. At last, the user resends the service request to the server through the client to perform the foregoing operation until the request acknowledgement is sent to the user before response timeout.
[0052] It is thus clear that the present invention uses a progress-indicating character set in the process of processing a service request as a basis for determining the processing progress of the current service request, so that when the process of processing the current service request is done, the server can automatically perform a rollback operation, and when if the process of processing the current service request has not been done, for avoiding Date Recue/Date Received 2022-04-21 system errors, the rollback operation is held, and only the progress-indicating character is changed at this moment, so that after the processing process is done, a rollback operation can be selectively performed on the service request that has not received a rollback operation according to the checking result of whether the progress-indicating character has been changed. This can effectively avoid the defect of system errors caused by improperly executing a rollback operation before the process of processing the service request has been done, thereby ensuring of good timing of activation of a rollback operation and stability of the system. In addition, as compared to the prior-art approach that deals with response timeout manually, the timeout processing method of the present invention is faster and more efficient.
[0053] It is understandable that in the present embodiment, the service request is a request for non-idempotent services. For helping people skilled in the art better understand the method for processing response timeout, the present invention will be further explained with the example of coupon locking.
[0054] When an on-line shopping user puts merchandise items in his shopping chat, he may submit his order with an applicable coupon. After the server receives the service request related to the order, the server immediately processes the service request and sends a request acknowledgement associated with the request to the client. Therein, the service request processing contains calls to the merchandise stock resources and promotion resources that lock the selected merchandise items and the selected coupon, respectively.
However, when a response timeout occurs during transmission of the request acknowledgement, the user has no idea whether the server has locked the selected merchandise items and the selected coupon. If a rollback operation is performed before the locking is done, the server can become unstable. However, it is unpractical to leave too much time to the serve for finishing the locking because this approach that sacrifices waiting time at the user side for processing response timeout can degrade shopping experience of users and is obviously unreasonable. Therefore, how to perform a rollback operation as soon as possible after the locking is done is the crucial problem to be solved in the present embodiment. The present invention uses a progress-indicating character set Date Recue/Date Received 2022-04-21 in the process of processing a locking operation as a basis for determining the processing progress of the current locking operation, so that when the process of processing the current locking operation is done, the server can automatically perform a rollback operation, and when if the process of processing the current locking operation has not been done, for avoiding system errors, the rollback operation is held, and only the progress-indicating character is changed at this moment, so that after the processing process is done, a rollback operation can be selectively performed on the locking operation that has not received a rollback operation according to the checking result of whether the progress-indicating character has been changed. This can effectively avoid the defect of system errors caused by improperly executing a rollback operation before the process of processing the locking operation has been done.

This can effectively avoid the defect of system errors caused by improperly executing a rollback operation before the process of processing the locking operation has been done.
[0055] Exemplarily, in Si of the embodiment described previously, the operation of setting the progress-indicating character in the process of processing the service request is achieved by: during the process of processing the service request, setting progress-indicating character using a setnx method stored in a redis cache. Optionally, the progress-indicating character is a state value.
[0056] Further, in S2 of the embodiment described previously, the operation of having the server feed a request acknowledgement back to the client, and when a response timeout occurs with respect to the request acknowledgement, determine whether the current service request has been processed by means of retrieving the progress-indicating character is achieved by:
[0057] having the server, based on an identification number of the current service request, retrieve the progress-indicating character in the process of processing the current service request; and if the current process has not ended and the progress-indicating character is retrieved, giving an output indicating that the process of processing the current service request has not been done, or, otherwise, giving an output indicating the process of processing the current service request is done. Exemplarily, the identification number of the service request is service serial number or service order number.
