運行grpc python示例必須使用sudo命令

Question

依賴於本教程grpc basic

我將https://github.com/grpc/grpc克隆到本地，

cd example/python/helloworld啟動服務器python greeter_server.py

然后啟動客戶端python greeter_client.py ，但出現錯誤

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}"

然后我執行sudo python greeter_client.py ，得到正確的結果。

為什么我應該添加sudo以獲得正確的結果？

Answer 1

1. 我發現我設置了一個全局http代理export http_proxy=http://127.0.0.1:1087 ，我關閉了該代理，然后找到了。

2. 更新greeter_client.py ，將localhost更改為127.0.0.1 。 找到我了。

Answer 2

您能否嘗試幾種選擇並分享您的反饋意見：

選項1

客戶端和服務器中的另一個端口（50051除外）？

選項2

在客戶端嘗試使用0.0.0.0
