[英]run grpc python example must use sudo command
依赖于本教程grpc basic
我将https://github.com/grpc/grpc
克隆到本地,
cd example/python/helloworld
启动服务器python greeter_server.py
然后启动客户端python greeter_client.py
,但出现错误
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?
我发现我设置了一个全局http代理export http_proxy=http://127.0.0.1:1087
,我关闭了该代理,然后找到了。
更新greeter_client.py
,将localhost
更改为127.0.0.1
。 找到我了。
