[0095] It should be noted that the method for obtaining the service call link provided in the embodiment of the present disclosure can generally be executed by the server 105. Accordingly, the device for obtaining the service call link provided in the embodiment of the present disclosure can generally be set in the server 105. The method for obtaining the service call link provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 105 and can communicate with the terminal devices 101, 102, 103 and / or the server 105. Accordingly, the device for obtaining the service call link provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 105 and can communicate with the terminal devices 101, 102, 103 and / or the server 105.

[0096] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0097] It should be noted that the method and device for obtaining the service call link determined in the embodiment of the present disclosure can be used for applications in the financial field in the field of testing technology, and can also be used in any field other than the financial field. The application field of the method and device for obtaining the service call link determined in the embodiment of the present disclosure is not limited.

[0098] The following will be based on Figure 1 The scene described by Figure 2 to Figure 6 The method for obtaining the service call link in the embodiment of the present disclosure is described in detail.

[0099] Figure 2 The flowchart of the method for obtaining the service call link according to the embodiment of the present disclosure is schematically shown. Figure 2 As shown, the method for obtaining the service call link of this embodiment includes operations S210 to S230, and the method can be executed by a server or other computing devices.

[0100] In operation S210, implementation class source files corresponding to all services in the service registration list are determined according to the service registration list.

[0101] According to an embodiment of the present disclosure, the service registration list is obtained by scanning a service provider configuration file.

[0102] In an example, in the Dubbo microservice framework, the service provider needs to register its own service in the provider.xml file, that is, the service provider configuration file. By scanning the service provider configuration file, all registered services can be obtained, that is, the full service registration list can be obtained, and the implementation class source file corresponding to each service in the list can be determined according to the service registration list. The process of obtaining the service implementation class source file will not be repeated here. Figure 3a Operations S211 to S212 are shown.

[0103] In operation S220, code scanning is performed on the implementation class source file according to a preset service calling rule to obtain a plurality of service calling relationships.

[0104] According to an embodiment of the present disclosure, the preset service calling rule is used to characterize the service calling form in the implementation class source file, and each of the service calling relationships is a calling relationship between two services.

[0105] According to an embodiment of the present disclosure, the service calling form includes function calling and annotation calling.

[0106] In one example, after obtaining the implementation class source file of any service, the source file code of the service is statically scanned according to the preset service call rules, wherein the preset service call rules refer to a variety of service call forms in the implementation class source file, including function calls, annotation calls and other forms of calls. Identify the code related to the preset service call rules, and then determine the caller and callee of the service. For example, in a certain line of code, determine that the method M1 of the service calls the service S1, and continue to search which services are called by the implementation class source file of the service S1, until a service is only called as the callee and does not call other services, then the search for the service call chain is completed. All source files can be subjected to the above scanning process to obtain all service call links. When the number of services is large and the call links are complex, it may happen that the same file is scanned multiple times, resulting in a long time and a reduced acquisition rate of the service call link. In order to improve the scanning efficiency, in the embodiment of the present disclosure, it is only necessary to scan all source files once to obtain multiple service call relationships, and the service call relationship only represents the call relationship between the two services, that is, the service call link obtained by operation S220 only includes the two services of the caller and the callee. For the specific static code scanning process, please refer to Figure 4 Operations S221 to S224 are shown and are not described in detail here.

[0107] In operation S230, a target function is called to generate a target service call link from the multiple service call relationships.

[0108] In one example, multiple service call relationships are connected in series by calling a target function to generate multiple complete service call links. The target function is used to connect multiple service call relationships in series to extend the service call link. The process of generating a target service call link based on multiple service call relationships can be found in Figure 5a The operations S231 to S233 are described.

[0109] A method for obtaining a service call link provided by an embodiment of the present invention obtains a service registration list by scanning a service provider configuration file, reverse compiles the service registration list to obtain an implementation class source file corresponding to the registered service, and uses static code scanning technology to scan the implementation class source file according to preset service call rules to generate multiple service call relationships, and then generates a target service call link, which makes the test more targeted, helps to improve test efficiency, and provides protection for safe production.

[0110] Figure 3a One of the flowcharts of the method for obtaining a service implementation class source file according to an embodiment of the present disclosure is schematically shown. Figure 3b The second flowchart of the method for obtaining the service implementation class source file according to the embodiment of the present disclosure is schematically shown. Figure 3a As shown, operation S210 includes operations S211 to S212.

[0111] In operation S211, registered service information is determined according to the service registration list.

[0112] According to an embodiment of the present disclosure, the registered service information includes a service name and an implementation class file name.

[0113] In operation S212, an implementation class source file of the service is determined according to the service name and the implementation class file name.

[0114] like Figure 3b As shown, operation S212 includes operation S2121 and operation S2122.

[0115] In operation S2121, an image file of the service is determined according to the service name and the implementation class file name.

[0116] In operation S2222, the image file is decompiled to generate an implementation class source file of the service.

[0117] In an example, the registered service information includes the service name, method name and implementation class file name. Taking F-PRRS (personal remittance) as an example, the registered service ATS CrossBorderRemitASM (cross-border remittance service) is found in provider.xml. The implementation class source file name corresponding to the service is com.xxx.xx.app.service.ATSCrossBorderRemitASMImpl. The mirror file of the cross-border remittance service is determined in the mirror database according to the implementation class source file name. Since the mirror file is a compiled file, the mirror file needs to be decompiled to generate the source code file of the service, that is, the implementation class source file.

[0118] Figure 4The flowchart of obtaining the service call relationship through static code scanning according to an embodiment of the present disclosure is schematically shown. Figure 4 As shown, operation S220 includes operations S221 to S224.

[0119] In operation S221, a target key field is determined according to a preset service calling rule.

[0120] In operation S222, the implementation class source file is scanned according to the target key field to determine the context code of the target key field.

[0121] In operation S223, the service caller and the service callee are determined according to the context code of the target key field.

[0122] In operation S224, a plurality of service calling relationships are generated according to the service caller and the service callee.

[0123] In an example, services at different layers under the Dubbo service framework mainly call each other through functions getbean, invokeService, invokeAsyncservice, and BeanUtil.getAsyncModule. In addition, each service can use annotations @autowired and @resources to implement bean injection and call each functional component. The above function call method and annotation are used as the target key fields, key field identification is performed, the context code of the target key field in the source code is located, the service caller and service callee in the context code are extracted, and a service call relationship is generated. In order to obtain the call relationship between two services, all source codes need to be scanned. The source code files in the source code directory are traversed. For each source code file, a line-by-line scanning method is used to extract what service is called by a specific method in the file according to the service call rules, so that a call relationship between two services in the form of service1→service2 can be obtained.

[0124] Take F-PRRS (personal remittance) as an example to illustrate the process and results of obtaining a service link. For example, the registered service ATS CrossBorderRemitASM (cross-border remittance service) is found in provider.xml, and its corresponding implementation class is com.icbc.prrs.app.service.ATSCrossBorderRemitASMImpl. By scanning the file, it can be found that the file contains the @autowired annotation, which introduces module A, and then the objects of this module are used in multiple methods of the service. For example, in the doRemit method of the service, object B created by the module is used. Then scan the CrossborderRemit file to find out whether other services or modules are called in method B. The search shows that the method calls component C, and further search shows that component C calls method D. Then search whether method D calls other services or modules, until the method no longer calls other services or components. After the above operations, multiple service call relationships can be obtained, A calls B, B calls C, and C calls D.

[0125] Figure 5a One of the flowcharts of the method for generating a target service call link according to multiple service call relationships according to an embodiment of the present disclosure is schematically shown. Figure 5b The second flowchart of the method for generating a target service call link according to multiple service call relationships according to an embodiment of the present disclosure is schematically shown. Figure 5c The third flowchart of the method for generating a target service call link according to multiple service call relationships according to an embodiment of the present disclosure is schematically shown. Figure 5a As shown, it includes operations S231 to S233.

[0126] In operation S231 , an input parameter of the target function is determined, wherein the input parameter is a single service name or a service chain.

[0127] In operation S232, the type of the input parameter is determined according to a preset identifier of the input parameter.

[0128] In one example, the incoming parameters of the target function are first determined. For example, all services that belong to the caller and are not the callee, that is, the target source service, can be screened out based on multiple service call relationships. For each screened target source service, the target function is called to continuously extend the call link of the target source service until a complete target service call link is generated. The input parameter of the target function is service, and the incoming parameter can be a single service name or a service chain. First, determine the type of the incoming parameter service, that is, whether it is a single service name or a service chain. Specifically, it can be determined based on whether there is a preset identifier in the incoming parameter, such as "-", "→", "@", etc., which represent service call relationships.

[0129] In operation S233, the plurality of service call relationships are cyclically searched according to the input parameter type until a target service call link is generated.

[0130] There are two feasible implementations of operation S233:

[0131] In one possible implementation, Figure 5b As shown, operation S310 to operation S340 are included.

[0132] In operation S310, when it is determined that the input parameter type is a service chain, an end service name of the service chain is acquired.

[0133] In operation S320, the plurality of service call relationships are searched according to the terminal service name to determine a first service list.

[0134] According to an embodiment of the present disclosure, the first service list is a set of services called by the terminal service.

[0135] In operation S330, each service in the first service list is added after the terminal service name to generate a plurality of service call links.

[0136] In operation S340, the plurality of service call relationships are searched cyclically to extend the plurality of service call links until a plurality of target service call links are generated.

[0137] In one example, when it is determined to be a service chain, the last service name in the service chain is determined and assigned to the variable tempsrv. The service call relationship is searched to obtain all services called by tempsrv to form the first service list calledbytempsrv. If calledbytempsrv is empty, it indicates that the current service is the last service in the service call chain, and the search ends. Each service in calledbytempsrv can be added as a callee to the original service or service call chain. If calledbytempsrv has n elements, n new service chains can be obtained: service→element 1, service→element 2,..., service→element n. Each new service chain obtained in operation S330 is assigned to service, and the above process is re-executed until multiple target service call links are obtained.

[0138] In another possible implementation, if Figure 5c As shown, operation S410 to operation S430 are included.

[0139] In operation S410, when it is determined that the input parameter type is a single service name, the multiple service call relationships are searched according to the single service name to determine a second service list.

[0140] According to an embodiment of the present disclosure, the second service list is a set of services called by the single service name.

[0141] In operation S420, each service in the second service list is added after the single service name to generate a plurality of service call links.

[0142] In operation S430, the plurality of service call relationships are searched cyclically to extend the plurality of service call links until a plurality of target service call links are generated.

[0143] In one example, the principles of operations S410 to S430 are roughly the same. When it is determined that the incoming parameter is a single service name, the single service name is assigned to the variable tempsrv. Search the service call relationship to obtain all services called by tempsrv to form a second service list calledbytempsrv. If calledbytempsrv is empty, it indicates that the current service is the last service in the service call chain, and the search ends. Each service in calledbytempsrv can be added as a callee to the original service or service call chain. If calledbytempsrv has n elements, n new service chains can be obtained: service→element 1, service→element 2, ..., service→element n.

[0144] For example, the following calling relationships between two services can be obtained through the first scan: A→B, B→C, C→D.

[0145] First, the service A parameter is passed in, and it is determined that the service calls service B, and the service chain A→B is obtained. The service chain is further input into the target function. After judgment, it is determined that the passed parameter is a service chain parameter, and the last called service name B in the service chain is determined. After searching, it is determined that service B calls service C. The service chain is further extended to: A→B→C, until the service at the end of the service chain cannot find a scenario to call other services, that is, service D is the last called service, then the service chain search ends, and the target service call link A→B→C→D is generated.

[0146] Since the preset service call rules only include commonly used call forms, sometimes developers do not call according to the specifications. Therefore, the service call rules in the embodiment of the present disclosure can also be dynamically updated and adjusted. Figure 6 Describes the update process of preset service call rules.

[0147] Figure 6 The flowchart of the preset service calling rule updating method according to the embodiment of the present disclosure is schematically shown, which specifically includes operations S510 to S530.

[0148] In operation S510, the target service call link is compared with the actual call link to determine an unknown service call link.

[0149] In operation S520, the unknown service call link is parsed to generate a target service call rule.

[0150] In operation S530, the preset service calling rule is updated according to the target service calling rule.

[0151] In one example, the target service call link obtained by static code scanning can be compared with the actual call link, which refers to the real call link that occurs during the actual transaction flow and is recorded by the holographic monitoring system. By comparing, it is determined that there is a service call link in the actual call link that does not exist in the target service call link, that is, an unknown service call link. By parsing the code file corresponding to the unknown service call link, a new target service call rule is abstracted, and the preset service call rule is updated. For example, Figure 4 The service call link obtained in the operation is ABCD. Service A is searched in the holographic monitoring system to obtain ABDEC. At this time, it is determined that service D calling service E is an unknown service call link. The code of the implementation class source files of service D and service E is analyzed, and the form of the service call is analyzed and abstracted into a calling rule, such as determining the corresponding calling function name or method name, and updating the rule to the preset service calling rule for subsequent code scanning.

[0152] Based on the above service call link acquisition method, the present disclosure also provides a service call link acquisition device. Figure 7 The device is described in detail.
