Description

Idempotent problem processing method, idempotent problem processing device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of data processing technologies, and in particular, to an idempotent problem processing method, apparatus, electronic device, and storage medium.

Background

When a user calls an interface of a platform, if a request is overtime, a problem of repeatedly executing a service request for many times may occur, and in the prior art, the processing mode for the request overtime mainly includes the following three types: firstly, when a calling party accesses a public service platform interface and times out, clear and definite reminding is returned to a user to inform that an execution result is unknown, and the user judges whether to retry or not, if the user sees the overtime reminding, the user initiates operations again, such as transfer, recharging and the like, and because the two operations are initiated by the user actively, the server cannot judge whether the transfer and recharging for the second time are new operations or are based on the last overtime retry behavior, the occurrence of repeated payment is caused; secondly, the calling party calls other interfaces to inquire the result of the overtime operation, determines whether the execution of the business corresponding to the overtime operation is successful or failed, and then processes the business based on the determined result, and the processing method has a problem that the operation result is convenient to inquire for not all business operations; thirdly, after the calling party encounters the interface overtime, the calling party directly initiates retry operation, so that the interface is required to support idempotent, and the code is independently written for each service logic which needs idempotent, so that the requirements on the development capability of programmers are high on one hand, and the development cost is high on the other hand.

In order to solve the above problems, the prior art adopts an optimistic lock mechanism, and uses a database redundancy version number field. The optimistic lock solves the problem of modifying scenes of calculation assignment type, and enables the calculation assignment type service to have idempotent property after the version number is added, but before the operation of the service, the optimistic lock needs to inquire the current vers ion version each time. Concurrent processing places tremendous pressure on the database.

Therefore, there is a need for a method for automatically rolling back when a server executes a service request abnormally by processing an idempotent problem, so as to prevent the problems of service downtime and idempotent failure.

Figure 3 illustrates a flow diagram of an idempotent problem processing method 200 according to one embodiment of the invention. As shown in fig. 2, in the method 200, a client carries idempotent information, a server handles an abnormal event in a process of executing a service request of the client according to the idempotent information of the client, the method 200 starts in step S210, and the server obtains the idempotent information carried by the client, where the idempotent information includes idempotent signs.

Specifically, the idempotent information carried by the client is acquired by the client from an idempotent tool, one idempotent tool generally comprises an idempotent generation management unit, a test unit, an idempotent protocol header unit, an idempotent operation interface unit, a high availability unit and a data consistency management unit, the idempotent tool has the functions of generating and managing the idempotent information, the client acquires the idempotent information from the idempotent tool, and the idempotent information comprises the idempotent.

Specifically, in an embodiment of the present application, the step of obtaining time information of a last login of a user to a server includes:

the server acquiring idempotent information carried by the client comprises the following steps:

a client acquires the idempotent request header information from an idempotent framework tool class; specifically, the client sends a request for obtaining the idempotent information to the idempotent framework tool class to obtain the idempotent request header information, the idempotent request header information is also the idempotent information, the idempotent request header information includes idempotent signs, and the idempotent signs are used for distinguishing different pieces of idempotent information obtained by different clients.

Acquiring idempotent request header information from an idempotent tool class according to the client, and sending an idempotent information request carried by the client to a server; specifically, when the client sends a service request to the server, in order to prevent abnormal problems from occurring and to deal with the abnormal problems in time and avoid the problem of service logic execution, the client simultaneously sends the acquired idempotent information to the server, and the server judges whether the service request of the client is processed according to whether the client carries the idempotent information.

The server judges whether the idempotent number of the idempotent information request exists or not;

if yes, the server processes the idempotent information request; specifically, if the idempotent sign exists, it indicates that the service request server sent by the client has not processed yet, and at this time, the server needs to process the idempotent information for the service request sent by the client first.

And if not, the server executes the service request of the client. Specifically, if the idempotent sign does not exist, it indicates that the server has completed executing the idempotent information carried by the client, and at this time, the service requested by the client may be processed.

Through step S220, according to the idempotent information carried by the client acquired by the server, the server acquires the idempotent information condition stored in the idempotent frame.

Specifically, for the idempotent information carried by the client, in the execution process of the server, the server needs to transmit the idempotent number to the corresponding interface implementation party according to the service request of the client, and the interface implementation party executes the service request of the corresponding client, for example, a panning user purchases a commodity from a panning store through a panning platform, at this time, the panning user simultaneously transmits the service request for purchasing the commodity and the information of the idempotent number to the panning server, and the panning server transmits the purchasing request for the panning user and the information of the idempotent number to the interface implementation party of the panning store according to the panning store selected by the user.

Specifically, in an embodiment of the present application, the step of, according to the idempotent information carried by the client acquired by the server, acquiring, by the server, the idempotent information condition stored in the idempotent frame includes:

according to the idempotent information carried by the client side, which is acquired by the server, the server transmits the idempotent information carried by the client side to an interface realizing side; specifically, the interface implementing party obtains the idempotent information carried by the client and also obtains the service request information of the client forwarded by the server to the interface implementing party.

According to the idempotent information carried by the client side and transmitted by the server, the interface realizing party analyzes the idempotent signs of the idempotent information;

according to the idempotent signs of the idempotent information analyzed by the interface realizing party, the interface realizing party transmits the idempotent signs to an idempotent frame;

and according to the idempotent information received by the idempotent frame, the server acquires the idempotent frame storage idempotent condition.

Specifically, after the interface implementation party analyzes the idempotent signs of the idempotent information, the interface implementation party judges whether the cache of the interface implementation party has the idempotent signs or not according to the analyzed idempotent signs, if the cache has the idempotent signs, the interface implementation party executes the interface implementation according to a scheme that the idempotent signs are stored in the cache, and if the cache does not have the idempotent signs, the interface implementation party stores the idempotent signs into a relational database and executes the interface implementation party according to the scheme that the idempotent signs are stored.

Specifically, in an embodiment of the present application, the obtaining, by the server, the case that the idempotent frame stores the idempotent includes:

according to the idempotent sign information received by the idempotent frame, the idempotent frame searches whether the idempotent sign already exists or not from a cache;

if the idempotent exists, sending the information that the idempotent exists to a server; specifically, the idempotent already exists in the cache, which indicates that the interface implementation party has already performed the execution of the service request of the client, or has completed the execution of the corresponding service request, and the idempotent is monitoring whether the service request executed by the interface implementation party is abnormal at this time, if so, the idempotent rolls back according to the corresponding scheme, and if so, the idempotent is processed according to the executed scheme.

If not, the power equivalent sign is stored in a relational database of the power framework. If the power-equal number does not exist in the cache, the service request sent by the client is not executed at the interface implementation party, and the interface implementation party needs to analyze the power-equal number, store the power-equal number in a relational database of the power-equal frame and execute the corresponding service request.

Specifically, in an embodiment of the present application, the step of storing the idempotent signs in the relational database of the idempotent frame includes:

acquiring a storage field of the power equal sign in the relational database;

setting a unique key for the storage field of the power-equal number in the relational database according to the storage field of the power-equal number in the relational database; specifically, if the server fails to execute the service request of the client, synchronization of the power-equal number in the cache may fail, and the server may not be rolled back after executing the exception, so as to achieve a correct execution result.

Storing the unique key and the power-idempotent into a relational database of the power-idempotent framework.

Through step S230, the abnormal event occurring during the execution of the server is handled according to the information of the idempotent sign stored in the idempotent frame.

Specifically, because the idempotent numbers in the idempotent frame have two forms, one is already in the cache, and the other is not in the cache, the idempotent numbers are stored in the relational database and synchronized into the cache after the business execution, for the idempotent numbers already in the cache, the business request of the client is executed by the server through an interface implementation party at the moment, the repeated execution of the business request is realized by calling through storing the idempotent numbers again, the idempotent numbers not in the cache need to be stored in the relational database firstly, and in order to prevent the cache synchronization failure, a field of the idempotent numbers stored in the relational database needs to be provided with a unique key, so that the client can roll back directly when the business request is executed abnormally.

Specifically, in an embodiment of the present application, the step of handling an abnormal event occurring in the execution process of the server according to the idempotent information stored in the idempotent framework includes:

if the power-equal number already exists in the cache, the server is executing the service request of the client;

if the power-equal number exists in the relational database, the server executes the service request of the client through the power-equal number in the relational database;

if the server executes the business request of the client through the power-equal number in the relational database, the server acquires the unique key of the power-equal number;

and rolling back the executed service request of the client by the server according to the unique key of the power equal number.

After the server executes the service request of the client through the idempotent in the relational database, the idempotent frame synchronizes the idempotent to a cache;

and setting a log clearing parameter of the idempotent frame, and deleting the idempotent log record in the relational database.

Specifically, in the process of service processing, the server can prevent a service system from being down and the power equal numbers from failing, in the application, records of the power equal numbers and execution of a service request of the client are put into one transaction, if the service request is successfully executed, the power equal numbers are inevitably recorded by a power equal frame, and if the service request is unsuccessfully executed, the power equal number records are automatically rolled back, so that the server executes the service request of the client again. In a relational database storing business data, a table is created to record power-equal numbers. The idempotent numbers are stored in a service database and then synchronized to the database of the idempotent framework.

In the embodiment of the application, when the idempotent framework is abnormal, normal recovery can be guaranteed, new business logic which cannot be executed can not be executed, because the idempotent function is temporarily failed and is repeatedly executed, errors can be caused to be executed on business requests, for example, the transfer is executed for multiple times, money is rotated for multiple times, and abnormal logic is executed on the idempotent framework

In order to make the idempotent framework as flexible as possible, make the business logic low-invasive, whether the abnormal occurrence allows the business logic to be retried and executed again, and the idempotent framework does not participate in the determination, the framework only needs to provide an interface for deleting the idempotent, and a business engineer determines whether to call the deleting interface and delete the recorded idempotent when the abnormal occurrence is encountered.

According to the power-idempotent problem processing scheme, power-idempotent information carried by a client is obtained through a server, and the power-idempotent information comprises power-idempotent signs; according to the idempotent information carried by the client side acquired by the server, the server acquires the idempotent information condition stored by the idempotent frame; and handling abnormal events which occur in the execution process of the server according to the situation of the idempotent information stored by the idempotent framework. The method and the device can prevent the server from being down when the server processes the service request of the client, can keep validity such as power, and can timely perform rollback processing when the server executes the service request of the client to be abnormal.

It should be understood that, although the steps in the flowchart of fig. 3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.

In one embodiment, as shown in fig. 4, there is provided an idempotent issue processing apparatus 300, where the apparatus 300 carries idempotent information by a client, and a server handles an abnormal event in a process of executing a service request of the client according to the idempotent information of the client, and the apparatus 300 includes: the device comprises an acquisition module, an idempotent analysis module and a treatment module.
