GRPC supports interceptor features, enhancing the flexibility and extensibility of GRPC.

Interceptor Usage

Server

Use grpcx.Server.ChainUnary to add extra server interceptors:

c := grpcx.Server.NewConfig()
c.Options = append(c.Options, []grpc.ServerOption{
    grpcx.Server.ChainUnary(
        grpcx.Server.UnaryValidate,
    )}...,
)
s := grpcx.Server.New(c)
user.Register(s)
s.Run()

Client

Use grpcx.Client.ChainUnary to add extra server interceptors:

conn = grpcx.Client.MustNewGrpcClientConn("demo", grpcx.Client.ChainUnary(
    grpcx.Client.UnaryTracing,
))

Interceptor List

The grpcx component of the framework offers a series of commonly used interceptors, some built-in and others optional.
