根因分析

客户端调用了服务端未注册的服务。通常是生成的客户端代码过旧、服务全限定名拼写错误，或服务端忘记调用 RegisterUserServiceServer。

English

The client called a service that the server has not registered. Usually a stale generated client, a typo in the fully-qualified service name, or a server that forgot to call RegisterUserServiceServer.

解决方案

  1. 95% 成功率 
    s := grpc.NewServer()
pb.RegisterUserServiceServer(s, &userServer{})
reflection.Register(s) // enables grpcurl discovery
log.Fatal(s.Serve(lis))
  2. 90% 成功率 
    // protoc --go_out=. --go-grpc_out=. user.proto
// then confirm: grpcurl -plaintext localhost:50051 list

无效尝试

常见但无效的做法:

  1. 95% 失败

    Unimplemented is a routing error on the server, not a TLS issue; disabling TLS does nothing for service lookup.

  2. 90% 失败

    The server will never learn the service; retries return Unimplemented deterministically.
