Twisted and Websockets: Beyond Echo

Question

In my ongoing curiosity about websockets, I\'m noticing a trend:

The \"hello world\" of the websocket universe, at least at the moment, seems to be \"echo\" function

Answer 1

This is an example of an updated EchoHandler that will instead of just being reactive, be proactive.

class ChattyHandler(WebSocketHandler):
    def connectionMade(self):
        self.transport.write('oh hai\n')
        self.saysomething()

    def saysomething(self):
        self.transport.write('still there?\n')
        reactor.callLater(5, self.saysomething)

Unfortunately, websockets from https://github.com/rlotun/txWebSocket/ doesn't seem to have the connectionMade() method, and instead the only thing you can hook into is the __init__. usually you would just override connectionMade() if it were a 'normal' twisted protocol. --Fixed in upstream
