Python WebSocket Server

#python

#websocket-server

After trying a couple of different implementations, I found tornado to work.

Here's the code pieced together from two sources:

Server:

from tornado import websocket
import tornado.ioloop

class EchoWebSocket(websocket.WebSocketHandler):
 def open(self):
 print "Websocket Opened"

 def on_message(self, message):
 self.write_message(u"You said: %s" % message)

 def on_close(self):
 print "Websocket closed"

application = tornado.web.Application([(r"/", EchoWebSocket),])

if __name__ == "__main__":
 application.listen(9000)
 tornado.ioloop.IOLoop.instance().start()

Client:

$(document).ready(function(){
 var socket = new WebSocket('ws://127.0.0.1:9000/');

 socket.onopen = function(event){
 socket.send('Hi');
 }

 socket.onmessage = function(event){
 console.log(event.data);
 };

 $(window).unload(function(event){
 socket.close();
 });
});

Tested in Firefox 15.01 and Chrome 22.0.1229.79.
