连接到运行在Go with python中的grpc服务时出现的问题

我在使用python库连接到运行在GO中的grpc服务时遇到问题

我正在使用图书馆

grpcio==1.10.1

这是我的密码

import grpc
from hello_world import hello_world_pb2_grpc
from hello_world import hello_world_pb2
channel = grpc.insecure_channel('localhost:5000')
stub =hello_world_pb2_grpc.CallStub(channel)
stub.Call()

在设置调试模式之后，当我这样做时，我得到了以下错误

channel = grpc.insecure_channel('localhost:5000')

这就是错误的样子

它显示它无法连接到给定端口上的给定服务。但是，其他服务可以连接到以其他语言编写的给定端口

另外，如果我使用telnet

localhost:5000

，它就能够连接

有什么问题吗？

您是否配置了代理？如果有，请查看取消设置http\U代理和https\U代理是否有效果：取消设置http\U代理；取消设置https\U代理；python hello\u world.py。@msmolens。我没有代理set@rajansthapit您是否尝试升级到最新的

grpcio

软件包？
