The present invention will be described in further detail with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it should be noted that the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, the method for automatically extracting recording flow provided by the invention comprises the following steps:
step 1, creating an automatic flow extraction task;
step 2, configuring a flow extraction rule;
Step 3, obtaining recording flow;
Step 4, starting an automatic flow extraction task, and filtering each recorded flow by adopting a flow extraction rule;
And step 5, sending the filtered recorded flow to a background management platform for rechecking to obtain the target sample flow.
In some embodiments, the configuration information of the flow extraction rule in step 2 includes a start extraction time, an end extraction time, a user ID to be extracted, a switch for extracting only a service successfully, an Http extraction field, a Dubbo extraction field, and a custom extraction rule expression.
In some embodiments, step 3 converts each acquired recording flow into a Map object.
In some embodiments, step 4 creates a flow extraction rule filter using JAVA, and adds the flow extraction rule filter to the process of obtaining the recorded flow, and performs filtering on the obtained recorded flow.
In some embodiments, step 4 includes: step 41, extracting the recording time of each recording flow based on the key value pair of the Map object of the recording flow, wherein the recording time is specifically as follows: obtaining recording time through map. Get ('CREATETIME'), setting the starting extraction time as T1 and the ending extraction time as T2, if the recording time is between the starting extraction time T1 and the ending extraction time T2, collecting the current recording flow into the first flow set, otherwise ignoring the current recording flow; step 42, extracting a login user ID of each recording flow in the first flow set based on a key value pair of the Map object of the recording flow, which specifically includes: obtaining login user IDs through map.get ('userId'), wherein a plurality of user IDs to be extracted are contained in a user ID list to be extracted, and if the login user IDs are the user IDs to be extracted contained in the user ID list to be extracted, collecting the current recording flow into a second flow set, otherwise, ignoring the current recording flow; step 43, extracting a status of whether the service of each recording flow in the second flow set is successful based on the key value pair of the Map object of the recording flow, specifically: and extracting a service state field through map. Get ("success") to obtain the state of whether the service is successful, wherein only the scene of success of the service is concerned, namely, the configuration information is a switch which only extracts the service successfully, and recording traffic of which the service is in a successful state is collected into a third traffic set, otherwise, the current recording traffic is ignored. The names of the CREATETIME, USERID parameters and the success parameters can be customized according to actual conditions.
Step 41 is the first filtering to filter out the flow in non-monitoring time; step 42 is a second filtering, filtering the traffic of the non-monitoring user; step 43 is the third filtering, and most of the traffic in the service failure scenario is filtered. The above three times of filtering can greatly reduce the size of the sample data to be extracted. If part of the traffic scenarios require interface errors, i.e. traffic failure scenarios, and thus traffic for such scenarios, step 43 is not required.
Typically, the interfaces related to login, menu and authorization are written in a control layer respectively, so that each type of traffic basically has the same prefix.
In some embodiments, step 4 further includes: if the recorded traffic is HTTP traffic, extracting a URL address of an HTTP interface of each recorded traffic in the third traffic set based on a key value pair of a Map object of the recorded traffic, specifically: and acquiring the URL address of the HTTP interface of the recorded flow through map. Get ('URL'), and if the URL address is the same as the HTTP extraction field, collecting the current recorded flow until the current recorded flow is ignored otherwise.
The Http extract field includes a URL address prefix and a postamble, where the postamble includes the following three means, the first: "is" means that any single character can be matched; second kind: "+" means that any number of characters (excluding path delimiters) can be matched; third kind: "x" means that any number of characters (including path splitters) can be matched. Setting the Http extraction field to "/user/" means that only all Http traffic beginning with "/user/" is extracted.
In some embodiments, step 4 further includes: if the recorded traffic is Dubbo traffic, extracting a service address of Dubbo interface of each recorded traffic in the third traffic set based on a key value pair of Map objects of the recorded traffic, specifically: and acquiring the service address of the Dubbo interface of the recorded traffic through map. Get ('SERVICEID'), and if the prefix of the service address is the same as the Dubbo extraction field, collecting the current recorded traffic, otherwise, ignoring the current recorded traffic.
Similarly, the Dubbo extraction field includes a service address prefix and a postamble, and the postamble also includes three modes ". Setting Dubbo the extraction field to "cn.demo.service.fan.userfacade/", indicates that only all Dubbo traffic beginning with "cn.demo.service.fan.userfacade/") is extracted.
The two filtering modes included in the above step4 may be set after the step 43, and the filtering is performed for the fourth time. The flow after the four times of filtering is very close to the final target flow, but when a developer writes codes, more similar interfaces are usually written in the same control layer at the same time, or very individual related interfaces are written in other unrelated control layers, so that a scene of extraction omission occurs. Preferably, the flow rate after four times of filtering can be corrected.
The invention can also set the custom extraction rule expression to meet different extraction requirements, and adapt to various abnormal scenes.
In some embodiments, step 4 further includes: and taking the Map object of the recorded flow as the whole context parameter, executing the custom extraction rule expression, and if the execution result is true, collecting the current recorded flow, otherwise, ignoring the current recorded flow. Such as: script Arrays. AsList (200,401) contains (code) then requires collection for a service state code (code) of 200 or 401, which is indicated as a login interface. Preferably, the custom extraction rule expression is Mvel expressions, each custom extraction rule expression is executed through mvel.eval (express, map), where express is a sentence string of the custom extraction rule expression, map is a context parameter including recording flow, mvel.eval is an execution engine method of an open source Mveal toolkit, mvel.eval execution result is true, current recording flow is collected, otherwise false ignores current recording flow.
After the multiple times of filtering, the filtered recorded flow is sent to a background management platform for rechecking, wherein rechecking comprises manually removing redundant recorded flow and manually adding missing recorded flow, and finally the target sample flow is obtained.
Finally, it should be noted that: the above embodiments are merely preferred embodiments of the present invention for illustrating the technical solution of the present invention, but not limiting the scope of the present invention; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions; that is, even though the main design concept and spirit of the present invention is modified or finished in an insubstantial manner, the technical problem solved by the present invention is still consistent with the present invention, and all the technical problems are included in the protection scope of the present invention; in addition, the technical scheme of the invention is directly or indirectly applied to other related technical fields, and the technical scheme is included in the scope of the invention.
