   --header "Content-Type: application/json" \
   --data '["Dubbo","hello"]' \
   http://localhost:50052/org.apache.dubbo.samples.tri.unary.GreetingsService/sayHi/

2. using map

   curl \
   --header "Content-Type: application/json" \

@AlbumenJ request payload will be determined by interface argument name, is it a good idea?

This is as expected

This is as expected

Assume another composite parameter exist:

public class CompositeBean implements Serializable {
  private String name;
  private String code;
  .... 
}
public interface GreetingsService {
  String sayHi3(String name, String message, CompositeBean source); 
}

I dont know what request should be.

["testName", "testMessage", {"name":"subName", "code": "subCode"}]

@AlbumenJ I have another question, does triple protocol allow method overload currently?

public interface GreetingsService {
  String sayHi3(String name, String message, CompositeBean source); 
  String sayHi3(String name, String message, SourceBean source);
}

  String sayHi3(String name, String message, SourceBean source);
}

For Triple in wrapper mode, we support. For Triple in plain http or grpc mode, we don't support.

Since dubbo support multi-protocols and different protocols have different constraints. It's better to ensure semantic consistency, make each Service protocol-insensitive. I recommend removing method overload support for all protocols.

That is a hope. Only a hope. Really really really hard~

        given:
            def request = new TestRequest(path: path)
        expect:
            runner.run(request, String.class) == output
        where:
            path                          | output
            '/say?name=sam&count=2'       | '2'
            '/say?name=sam'               | '1'
            '/say~SL'                     | '2'
            '/say~S'                      | '1'
            '/say~S?name=sam&count=2'     | '1'
            '/say~S.yml?name=sam&count=2' | '1'
    }

    String say(String name, Long count)

    String say(String name)

In the latest REST Triple, support method override has been added by passing the method signature abbreviation.
