node.js - How to get response on python client from a nodeJS server -

i'm trying build simple chat app using nodejs server socket.io , client written in python 2.7 using socketio-client package. js server on local , simple :

io.on('connection', function(socket){     socket.on("chat_message", function(msg){         io.emit("chat_message", msg);                    }); }); 

this chat app works several pages opened in browser. (source comes : http://socket.io/get-started/chat/ )

i wanted connect server python client, , succesfully emit python js server (text entered in python client appears browser).

the problem following : when type text browser, python doesn't print shell.

here code use on python side :

def communicate(self, msg):     logging.debug('processing event : %s', msg)          self.socketio.emit("chat_message", msg, self.on_chat_message)  def on_chat_message(self, *args):     output = ''     index = 0     in args:         output += ' | '+str(index)+' : '+str(a)         index += 1      logging.debug('processing server output : ' + output)        return 

as server emits connected clients, python should handle callback 'on_chat_message' but, doesn't work.

i tried add self.socketio.wait_for_callbacks() python, without success.

if has idea i'm doing wrong, great =d ! thanks.

i managed response server on python client.

my mistake not 'wait' on socketio variable, didn't catch feedback.

to handle server responses, use basenamespace class binded socket, , handle basic events : overriding of function on_event

def on_event(self, event, *args):     #catch event , stuff 

if event handled class, flag raised , checked client.

def communicate(self, msg):          self.socketio.emit('chat_message', msg)  def wait_for_server_output(self):     while(1):         self.socketio.wait(seconds=1)         ns = self.socketio.get_namespace()         if ns.flag.isset():             data = ns.data_queue.get()             ns.flag.clear() 

these 2 functions managed 2 threads inside client code.

hoping =)
