依赖本教程grpc basic

我克隆https://github.com/grpc/grpc到本地，

cd example/python/helloworld 启动服务器python greeter_server.py

然后启动客户端python greeter_client.py，但得到错误

Traceback (most recent call last):
  File "greeter_client.py", line 35, in <module>
  run()
  File "greeter_client.py", line 30, in run
    response = stub.SayHello(helloworld_pb2.HelloRequest(name='you'))
  File "/usr/local/lib/python3.7/site-packages/grpc/_channel.py", line 533, in __call__
    return _end_unary_response_blocking(state, call, False, None)
  File "/usr/local/lib/python3.7/site-packages/grpc/_channel.py", line 467, in _end_unary_response_blocking
    raise _Rendezvous(state, None, None, deadline) grpc._channel._Rendezvous: <_Rendezvous of RPC that terminated with:
      status = StatusCode.UNAVAILABLE
      details = "Socket closed"
      debug_error_string = "{"created":"@1541228979.471085000","description":"Error received from peer","file":"src/core/lib/surface/call.cc","file_line":1017,"grpc_message":"Socket closed","grpc_status":14}"

然后我执行sudo python greeter_client.py，得到正确的结果。

为什么我应该添加 sudo 以获得正确的结果？

  1. 我发现我设置了一个全局 http 代理export http_proxy=http://127.0.0.1:1087，我关闭了这个代理，然后就找到了。

  2. 更新greeter_client.py，更改localhost为127.0.0.1. 对我来说是找到的。

您能否尝试几个选项并分享您的反馈：

选项1

客户端和服务器中的另一个端口（50051 除外）？

选项 2

在客户端尝试使用 0.0.0.0

谢谢， Dheeraj
