我正在尝试运行本指南中的 websocket 示例代码:http://bottlepy.org/docs/dev/async.html

网站上提供的代码不起作用。我尝试尽可能少地编写代码，但它没有改变任何东西。这是我的最终版本。

服务器端:

from bottle import request, Bottle, abort
app = Bottle()

@app.route('/websocket')
def handle_websocket():
    return "Hello"

from gevent.pywsgi import WSGIServer
from geventwebsocket import WebSocketError
from geventwebsocket.handler import WebSocketHandler
server = WSGIServer(("0.0.0.0", 8080), app,
                handler_class=WebSocketHandler)
server.serve_forever()

客户端:

<!DOCTYPE html>
<html>
<head>
 <meta charset="UTF-8"> 
  <script type="text/javascript">
    var ws = new WebSocket("ws://localhost:8080/websocket");
  </script>
</head>
</html>

服务器打印以下错误跟踪。出了什么问题？

最佳答案

geventwebsocket 尚未完全支持 Python 3(截至 2016 年 5 月 2 日)。
