How to make two Python Tornado websocket channels available at different URLs

Question

I have two queues that should be subscribed to separately when opening a websocket connection to either endpoint. One should be ws://127.0.0.1:8000/channel_one and the other is ws://127.0.0.1:8000/channel_two.

How do I implement this URL structure in Python Tornado and make it so there are two endpoints in the same program?

Answer 1

Adapting the sample hello world app:

import tornado.web
import tornado.websocket

class HandlerOne(websocket.WebSocketHandler):
    pass

class HandlerTwo(websocket.WebSocketHandler):
    pass

def make_app():
    return tornado.web.Application([
        (r"/channel_one", HandlerOne),
        (r"/channel_two", HandlerTwo),
    ])

if __name__ == "__main__":
    app = make_app()
    app.listen(8000)
    tornado.ioloop.IOLoop.current().start()
