Python客户端连接WebSocket服务器报错[Errno 11001] getaddrinfo failed

我尝试使用Python通过WebSocket连接Web服务器，但始终无法成功，持续收到错误：[Errno 11001] getaddrinfo failed

客户端代码 #

import asyncio
import websockets
from websockets.sync.client import connect


def connection():
    with connect("ws://http://<ip address>") as ws:
        ws.send("Hello world!")
        message = ws.recv()
        print(f"Received: {message}")


if __name__ == "__main__":
    connection()

报错信息 #

line 14, in <module>
    connection()

line 7, in connection
    with connect("ws://http://<ip address>/") as ws:

line 247, in connect
    sock = socket.create_connection(

line 824, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):

line 955, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 11001] getaddrinfo failed

解决方法 #

已解决该问题，原因是忘记在Windows的hosts文件（路径为C:\Windows\System32\drivers\etc\hosts）中添加IP地址与主机名的映射，添加以下内容并保存后，问题即可解决：

<ip address> <hostname>
