解决方案

  1. 100% 成功率 
    lis, _ := net.Listen("tcp", ":50051"); s := grpc.NewServer(); pb.RegisterGreeterServer(s, &server{}); s.Serve(lis)
  2. 90% 成功率 
    Ensure client dials the correct address: grpc.Dial("localhost:50051", grpc.WithInsecure())

无效尝试

常见但无效的做法:

  1. 90% 失败

    The server is not listening on any port.

  2. 50% 失败

    Firewall is not the issue if the server is not running.
