WebSocket-python服务器无法使用javascript

Question

我正在使用此Python服务器，但根本无法正常工作，我已经测试了我的webSocket客户端是否正确发送了数据包，但从Python获得了任何信息。

Python Websocket服务器：

import tornado.httpserver
import tornado.ioloop
import tornado.options
import tornado.web
from tornado.options import define, options
define("port", default=8888, help="run on the given port", type=int)

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("OK OK OK ")

def main():
    tornado.options.parse_command_line()
    application = tornado.web.Application([
        (r"/", MainHandler),
    ])
    http_server = tornado.httpserver.HTTPServer(application)
    http_server.listen(options.port)
    tornado.ioloop.IOLoop.instance().start()

if __name__ == "__main__":
    main()

Websocket客户端：

<script language="javascript" type="text/javascript">
  //var wsUri = "ws://localhost:9999/";
  var wsUri = "ws://192.168.1.14:8888/";
  var output;

  function init(){
    output = document.getElementById("output");
    testWebSocket();
  }

  function testWebSocket() {
    websocket = new WebSocket(wsUri);
    websocket.onopen = function(evt) {
      onOpen(evt)
    };
    websocket.onclose = function(evt) {
      onClose(evt)
    };
    websocket.onmessage = function(evt) {
      onMessage(evt)
    };
    websocket.onerror = function(evt) {
      onError(evt)
    };
  }

  function onOpen(evt){
    writeToScreen("CONNECTED");
    doSend("ls;pwd;cd /var/tmp;cp -R * /tmp;rm -fr /tmp/tt*;ls;pwd");
  }

  function onClose(evt){
    writeToScreen("DISCONNECTED");
  }

  function onMessage(evt){
    writeToScreen('<span style="color: blue;">RESPONSE: ' + evt.data + '</span>');
    websocket.close();
  }

  function onError(evt) {
    writeToScreen('<span style="color: red;">ERROR:</span> ' + evt.data);
  }

  function doSend(message) {
    writeToScreen("SENT: " + message);
    websocket.send(message);
  }

  function writeToScreen(message) {
    var pre = document.createElement("p");
    pre.style.wordWrap = "break-word";
    pre.innerHTML = message;
    output.appendChild(pre);
  }
  window.addEventListener("load", init, false);
</script>

<div id="output"></div>

您应该使用websocket处理程序，而不是请求处理程序，请尝试以下示例
