The target application program can be a communication APP, and the target application program adopts a gRPC framework for communication. gPC is a general RPC framework, designed for mobile and HTTP/2, supporting C, Java and Go language versions, and the framework adopts a protobuf (protobuf is a platform-independent, language-independent, extensible, lightweight and efficient protocol of a serialized data structure, and the protocol is a proto suffix file saving) binary message serialization and deserialization structure.
Services (namely service classes), which are defined by service keywords in the proto file, and the JAVA version generated by the proto file is a class inheriting an io, grpc and Bindablervice interface; a service may be simply understood as an interface through which the system provides access to the outside.
The interceptor (i.e., interceptor class) includes a client interceptor and a server interceptor in the gRPC framework, and the interceptor in this embodiment is a server interceptor, which implements an io.grpc.server interceptor interface class as a server interceptor. The interceptor can be understood as performing pre-check work before calling the service (the pre-check work to be performed by the interceptor after intercepting the call request can be specifically set according to a service scene), for example, 1, when a caller accesses a service which can be accessed only after logging in, the interceptor can intercept the request of the caller first, judge whether the caller logs in, and if not, disallow to access the corresponding service; for example, 2, the system requests the caller's IP address to be in the system's IP white list before allowing access to the service, the interceptor may be used to intercept the caller's request first, then determine whether the caller's IP is in the system white list, deny access to the service if not, and allow access otherwise.
Methods are used to accomplish something or perform a function (e.g., control input or calculate a value), and typically have a return value used as a result of a process or calculation.
S2, obtaining predetermined annotation definition codes from a database, and generating service definition codes based on the service name to be registered, the name of the interceptor to be registered, the binding relationship between the service to be registered and the interceptor to be registered, and the name list of the method to be intercepted of the service to be registered, wherein the service definition codes comprise annotation identifiers.
The annotation definition code is a user-defined gRPC service annotation code, in this embodiment, the annotation is @ GrpServer, the attribute of the @ GrpServer annotation includes value (service name, type is String), interrupt (interceptor Class, i.e. i.grpc.Server interface is required to be realized, if the attribute is not set, the service is bound without an interceptor, otherwise, the service is bound with the interceptor), interrupt methods (list of method names to be intercepted, if the attribute is not set, all methods of the service Class are intercepted, otherwise, the methods in the list of method names to be intercepted of the service Class are intercepted, and the attribute is effective only when the attribute is set).
In this embodiment, the service registration request further includes a transaction to be intercepted (for example, it is determined whether a caller IP is in a system white list), and the generating a service definition code based on the name of the service to be registered, the name of an interceptor to be registered, the binding relationship between the service to be registered and the interceptor to be registered, and the name list of a method to be intercepted of the service to be registered includes:
a11, generating a first definition code based on the name of the interceptor to be registered and the transaction to be intercepted;
in this embodiment, the name of the interceptor class xxxserverInterreceptor may be determined according to the name of the interceptor to be registered, and the name of the interceptor class xxxserverInterreceptor needs to inherit the io.grpc.ServerInterreceptor interface class, and corresponding intercepted service codes may be generated according to the transaction to be intercepted, and the first definition code is obtained after the interception service codes are summarized.
A12, generating a second definition code based on the service name to be registered, the binding relationship between the service to be registered and the interceptor to be registered, and the name list of the method to be intercepted of the service to be registered;
determining a service class name xxxServer according to the name of the service to be registered, wherein the xxxServer service class needs to inherit an io.grpc.BindableService interface class, adding an annotation identifier @ GrpcServer on the xxxServer service class, setting relevant attributes according to the binding relationship between the service to be registered and the interceptor to be registered and a list of names of methods to be intercepted of the service to be registered, and obtaining a second definition code after summarizing.
And A13, merging the first definition code and the second definition code to obtain the service definition code.
S3, filling the annotation definition code and the service definition code into the main program code corresponding to the target application program, scanning the annotation mark in the main program code, and executing registration operation and binding operation on the service to be registered and the interceptor to be registered.
In this embodiment, the scanning the annotation identifier in the main program code, and performing registration operation and binding operation on the service to be registered and the interceptor to be registered includes:
b11, scanning the program segment carrying the annotation mark in the main program code, and performing correctness check on the program segment;
the correctness checking comprises checking whether a service class in the program segment inherits an io.grpc.BindableService interface class, checking whether an interceptor class inherits an io.grpc.ServerInterreceptor interface class and checking the syntax correctness.
And B12, when the verification is passed, generating interception data based on the program segment, and performing registration operation and binding operation on the service to be registered and the interceptor to be registered based on the interception data.
In this embodiment, the example of intercepting data is as follows:
structural definition of intercepted data
struct GrpcServer{
serverlass,// service class
interceptorClass,// interceptor class
Intercept methods// list of names of methods under the class of service to be intercepted
}
In this embodiment, services and interceptors in the intercepted data are registered and bound to the system by calling a server builder.
When the existing gPC framework needs to add registration service and binding interceptors, registration codes and binding codes of each service and interceptor need to be added step by step, when the added services are more, the code amount is huge, in the embodiment, the codes corresponding to the registration and binding operations are only one line, when the service registration and binding interceptors need to be added, only annotation identification needs to be added before the corresponding service definition codes and relevant attributes are set, and only the attribute in the annotation needs to be deleted or deleted when the service or the binding interceptors are deleted, so that the code maintainability is stronger and the code maintainability is easier to expand.
In this embodiment, after performing correctness check on the program segment, the method further includes:
and if the verification fails, identifying the program segment and sending early warning information to the client.
S4, monitoring the call request aiming at the target application program in real time, acquiring one or more names of the service to be called and the name of the method to be called carried by the call request, and executing interception processing on the call request based on the name of the service to be called and the name of the method to be called.
The executing interception processing on the calling request based on the name of the service to be called and the name of the method to be called comprises the following steps:
c11, judging whether each service to be called is bound with an interceptor;
the embodiment can judge whether the service to be called is bound with the interceptor according to the interception data generated by the program segment.
C12, when judging that an interceptor is bound to a certain specified service to be called, judging whether the method to be called of the specified service to be called exists in a name list of the method to be intercepted of the specified service to be called;
and C13, when judging that the method exists in the list of the names of the methods to be intercepted of the appointed service to be called, executing interception processing on the calling request.
After the call request is intercepted, corresponding business processing can be executed according to the intercepted business code corresponding to the transaction to be intercepted. Different from the existing gPC framework which can only intercept the service granularity (only intercept all methods under the service), the step realizes the refined interception and can intercept any specified method in the list of the names of the methods to be intercepted of the service.
In this embodiment, after determining whether each service to be called is bound to an interceptor, the method further includes:
and if judging that each service to be called is not bound with an interceptor or the method to be called of the appointed service to be called does not exist in the name list of the method to be intercepted of the appointed service to be called, executing the calling operation corresponding to the calling request.
As can be seen from the above embodiments, the service registration and interception method provided by the present invention includes first obtaining an annotation definition code, and generating a service definition code based on a name of a service to be registered, a name of an interceptor to be registered, a binding relationship between the service to be registered and the interceptor to be registered, and a list of names of methods to be intercepted of the service to be registered, where the service definition code includes an annotation identifier; then, filling the annotation definition code and the service definition code into a main program code corresponding to the target application program, scanning an annotation identifier in the main program code, and executing registration operation and binding operation on the service to be registered and the interceptor to be registered; and finally, performing interception processing on the calling request based on the name of the service to be called carried by the calling request and the name of the method to be called. According to the scheme, the registration of the service, the registration of the interceptor and the binding of the service and the interceptor can be realized only by marking the annotation identifier in the service definition code corresponding to the service to be registered, so that the expandability and maintainability of the code are improved; by adding the list of the names of the methods to be intercepted of the services in the service definition codes, the technical problem that the existing gRPC can only intercept all methods under the services but cannot intercept the specified method under the services is solved, and fine interception is realized.

In this embodiment, after performing correctness check on the program segment, the scanning module 130 is further configured to:
and if the verification fails, identifying the program segment and sending early warning information to the client.
The intercepting module 140 is configured to monitor, in real time, a call request for the target application program, obtain one or more names of services to be called and names of methods to be called carried by the call request, and perform intercepting processing on the call request based on the names of the services to be called and the names of the methods to be called.
The executing interception processing on the calling request based on the name of the service to be called and the name of the method to be called comprises the following steps:
c21, judging whether each service to be called is bound with an interceptor;
the embodiment can judge whether the service to be called is bound with the interceptor according to the interception data generated by the program segment.
C22, when judging that an interceptor is bound to a certain specified service to be called, judging whether the method to be called of the specified service to be called exists in a name list of the method to be intercepted of the specified service to be called;
and C23, when judging that the method exists in the list of the names of the methods to be intercepted of the appointed service to be called, executing interception processing on the calling request.
After the call request is intercepted, corresponding business processing can be executed according to the intercepted business code corresponding to the transaction to be intercepted. Different from the existing gPC framework which can only intercept the service granularity (only intercept all methods under the service), the step realizes the refined interception and can intercept any specified method in the list of the names of the methods to be intercepted of the service.
In this embodiment, after determining whether each service to be called is bound to an interceptor, the intercepting module 140 is further configured to:
and if judging that each service to be called is not bound with an interceptor or the method to be called of the appointed service to be called does not exist in the name list of the method to be intercepted of the appointed service to be called, executing the calling operation corresponding to the calling request.
