Authentication

server

• http

• grpc

grpcSrv := grpc.NewServer(
    grpc.Address(":9000"),
    grpc.Middleware(
            return []byte(testKey), nil
        }),
    ),
)

client

• http

conn, err := http.NewClient(
    context.Background(),
    http.WithEndpoint("127.0.0.1:8000"),
        jwt.Client(func(token *jwtv4.Token) (interface{}, error) {
            return []byte(serviceTestKey), nil
        }),
    ),
)

Options

WithSigningMethod()

Used to set the sigining method.

For examples：

jwt.WithSigningMethod(jwtv4.SigningMethodHS256)

WithClaims()

For examples：

• For client:

claims := &jwtv4.StandardClaims{}
jwt.WithClaims(func()jwtv4.Claims{return claims})

• For server

A simple

In particular, client is set to visit a service listening the port 9001. And that service should set a key as the same as the client one named .

con, _ := grpc.DialInsecure(
    context.Background(),
    grpc.WithEndpoint("dns:///127.0.0.1:9001"),
    grpc.WithMiddleware(
        jwt.Client(func(token *jwtv4.Token) (interface{}, error) {
            return []byte(serviceTestKey), nil
        }),
    ),
)

Extract Users’ Information

Under the hook, after processing by the middleware, the claims information would be stored into the context. One should assert the claims as the type that is used to create the token before using it.

With selector middleware, one could setup white list. Ref:
