Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0043] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0044] With the development of Internet technology, various applications have gradually enriched our lives. The successful launch of an application requires a series of testing links. In order to reduce the time of generating test data and improve test efficiency, traffic replay is often used. Traffic replay: Test data is no longer artificially generated, but directly copied from online traffic data. The copied part of the traffic is sent to the tested cluster, which is equivalent to a replay of the online traffic in the test environment, thereby achieving the effect of automatic replay. Then this part of the traffic is precipitated to form a use case so that it can be used next time.

[0045] The specific application scenarios of traffic playback include: for example, a user wants to query the credit status of Zhang San through the credit service through the client. The client records the message corresponding to the query operation performed by the user. When querying again, the recorded message can be directly sent to realize the process of re-querying. There is no need to go to the interactive interface to perform the query operation again, which simplifies the workflow and improves work efficiency. On the other hand, when performing software testing, it is necessary to manually generate test data and record the process of manually generating test data. When generating test data again, the recorded process of generating the test data can be replayed.

[0046] The existing traffic playback method, after recording the traffic data, plays back the recorded original traffic data. This traffic playback method is only applicable to the case where the business scenario is a single interface. When the business scenario is a workflow, this traffic playback method will not be implemented.

[0047] Based on this, the embodiments of the present application provide a method, device, electronic device and storage medium for traffic playback, which are described below through embodiments.

[0048] Figure 1 A flow chart of a method for traffic playback provided in an embodiment of the present application is shown, wherein the method includes steps S101-S103; specifically:

[0049] S101, responding to a business operation for a target business, recording target flow data corresponding to the business operation; the target flow data contains message data of each interface in the business process;

[0050] S102, analyzing the message data of each interface, determining the association relationship and associated data between the message data of each interface, and parameterizing the associated data to obtain parameter data corresponding to the associated data;

[0051] S103 . In response to the first playback operation for the target service, the message data of each interface is sent again according to the association relationship and the initial value corresponding to the parameter data to complete the first traffic playback.

[0052] The present application analyzes the message data in the interface and parameterizes the associated data in the message data, thereby realizing multiple traffic playbacks and improving work efficiency.

[0053] Some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0054] S101. Respond to a service operation for a target service and record target flow data corresponding to the service operation; the target flow data contains message data of each interface in the service process.

[0055] Traffic playback is the process of recording the interface messages sent by the client to the server and then using these messages to send requests to the server again. The role of the client device is to perform related business operations for the user. For example, the client device can be a device with data transmission function close to the user side, such as a mobile terminal, TV, computer, PDA, etc. When performing business operations, the user operates the client to send messages to the server.

[0056] Existing businesses generally correspond to a business flow, that is, multiple interface requests are required to complete a business process. For example, customer A wants to apply for a loan from a bank. This business process requires the account manager to create a credit application task (task number: e001). Then this application task needs to be approved by the branch, the sub-branch and the head office in turn, and finally the credit application for customer A can be confirmed. In this approval process, the approval process can only be completed by going through the approval nodes of the account manager, branch, sub-branch and head office. In this approval process, the client needs to send different interface messages to the server to complete the approval process. If only part of the process is recorded during recording (for example, only e001 is recorded), when replaying, the system will prompt that the part of the process has been completed (that is, number e001 has been approved), and it cannot be approved again. The reason for this situation is that when the traffic is replayed, number e001 is a fixed value, and the fixed value is used every time it is replayed, resulting in the existence of e001. In fact, there are many parameters before and after a business process, far more than the quota application number e001.

[0057] For the above business flow, this application records the target flow data corresponding to the business operation when the user performs business operations on the client. The recording tool here can be a Fiddler tool, or a built-in tool library, etc. The target flow data in this application contains the message data of each interface in the business process.

[0058] When recording traffic, there may be duplication in the traffic. In order to avoid redundant processing and improve processing efficiency, this application obtains the target traffic data in the following way. Figure 2 As shown. Including S201 and S202:

[0059] S201, responding to a service operation for a target service, recording initial traffic data corresponding to the service operation;

[0060] S202: Filter out target flow data from the initial flow data according to the similarity between the initial flows and a preset similarity threshold.

[0061] That is to say, when recording the business process, the present application first records the initial traffic data, and then screens the initial traffic data according to the similarity between the initial traffic data, removes the initial traffic data with higher similarity, and then obtains the target traffic data.

[0062] S102: Analyze the message data of each interface, determine the association relationship and associated data between the message data of each interface, and perform parameterization processing on the associated data to obtain parameter data corresponding to the associated data.

[0063] After obtaining the message data of each interface, the present application needs to analyze the message data to determine whether there is an association relationship and associated data between the message data of each interface. The message data in the present application includes request headers, request body, response body and request address (url).

[0064] Analyze the message data of each interface to determine the association relationship and associated data between the message data of each interface, including:

[0065] The request headers of two adjacent interfaces are compared. If the request headers of the two interfaces are inconsistent and the request headers of the two interfaces contain the same value, the two interfaces have an association relationship, and the same value is used as association data.

[0066] The request bodies or the request bodies and response bodies of two adjacent interfaces are compared. If the request body of one interface contains the same value as the request body or response body of another interface, the two interfaces have an association relationship, and the same value is used as association data.

[0067] If the request bodies of the two interfaces do not contain the same value, the two interfaces are not associated;

[0068] The comparison is continued using the target interface which is located earlier of the two interfaces and the previous interface of the target interface.

[0069] The request addresses and response bodies of two adjacent interfaces are compared. If the request address of one interface has the same value as the return message response body of the previous interface, the two interfaces have an association relationship, and the same value is used as association data.

[0070] If the request address of an interface does not have the same value as the return message response body of the previous interface, the two interfaces are not associated;

[0071] The comparison is continued using the target interface which is located earlier of the two interfaces and the previous interface of the target interface.

[0072] When it comes to specific implementation, the recorded interfaces are analyzed to find out the interfaces that are associated with the previous and next messages, and the associated data is parameterized, such as the credit application number e001. The interfaces that are associated with the previous and next messages mainly analyze the request header, request body, and response body of the message. Traverse the interface: compare the request header of the latter interface with the request header of the previous interface to see if they are consistent. If not, determine whether certain values ​​in the request header of the latter interface appear in the response body of the return message of the previous interface. If so, then identify that the two interfaces are associated, and parameterize the same values ​​they have (parameterization means that when you build a model or write a program, you use variables to represent the feature size, and drive the model or program changes by changing the variables). In other words, this application replaces the same values ​​of the two with variables, and by assigning different values ​​to the variables, it can avoid the problem of data being considered to already exist during traffic playback. You can also judge the content in the request body of the latter interface to determine whether the content in the request body of the interface appears in the request body of the return message of the previous interface, or determine whether the content in the request body of the interface appears in the request body of the request message of the previous interface. If so, then identify that the two interfaces have an association relationship, and parameterize the same content (value) in the two. If not, continue to traverse to the previous interface. You can also determine whether the fields in the current request address url appear in the request body of the return message of the previous interface. If so, then identify that the two interfaces have an association relationship, and parameterize the same values ​​in the two. If not, traverse to the previous interface again.

[0073] S103 . In response to the first playback operation for the target service, the message data of each interface is sent again according to the association relationship and the initial value corresponding to the parameter data to complete the first traffic playback.

[0074] Use jvm-sandbox-repeater to replay the traffic. If the replay result is consistent with the recorded result, it means that the code change does not affect the original business process. If the replay result is different from the recorded result, it means that the code change affects the original business process. You need to analyze the reasons for the impact on the original business based on the difference in results.

[0075] In the embodiment of the present application, as an optional embodiment, the initial value of the parameter data is updated to obtain the updated value of the parameter data;

[0076] In response to the replay operation for the target service, the message data of each interface is sent again according to the association relationship and the updated value corresponding to the parameter data to complete the replay of the traffic.

[0077] The present application obtains parameter data corresponding to the associated data by parameterizing the associated data. Multiple traffic playbacks can be realized. When the traffic is first played back, the initial value of the parameter data is used. When the traffic is played back again, the initial value of the multi-parameter data needs to be updated, and the initial value is updated to the updated value, and the traffic is played back again based on the updated value.

[0078] In the embodiment of the present application, as an optional embodiment, the specific parameterization process in the present application is: deeply traverse the request body, take the value value and match it with the corresponding data, and mark the value value of the request body. The value value of the corresponding data is identified by using the jsonpath expression as the key value, and the corresponding data value is stored in a public variable during subsequent operation. When the value value of the marked request body is encountered, it is replaced with the corresponding value value.

[0080] A recording module, used to respond to a business operation for a target business and record target flow data corresponding to the business operation; the target flow data contains message data of each interface in the business process;

[0089] If the request bodies of the two interfaces do not contain the same value, the two interfaces are not associated;
