client.py

import asyncioimport websockets  async def hello(uri):    async with websockets.connect(uri) as websocket:        while True:            recv_text = await websocket.recv()  # 接管音讯            print(recv_text)          if __name__ == '__main__':    asyncio.get_event_loop().run_until_complete(        hello('ws://127.0.0.1:5000')) # 改为你本人的地址
  1. pip装置websockets
  2. 先启动server.py，再启动client.py。
  3. 成果：

在网页上展现。client.html

<!DOCTYPE html><html>    <head>        <title>WebSocket demo</title>    </head>    <body>        <script>            var ws = new WebSocket("ws://127.0.0.1:5000/"),                messages = document.createElement('ul');            ws.onmessage = function (event) {                var messages = document.getElementsByTagName('ul')[0],                    message = document.createElement('li'),                    content = document.createTextNode(event.data);                message.appendChild(content);                messages.appendChild(message);            };            document.body.appendChild(messages);        </script>    </body></html>

启动server.py后再点开页面，成果：
