App

Event based app for websocket communication.

This is app that uses Framework. If not events handled by developer. this app works like demo(echo) app. This is a WSGI web app. So you can use any WSGI Server to host this app

You should use HTTP version 1.1 Server with your WSGI framework for some clients like Firefox browser.

from wsocket import WSocketApp, WebSocketError, logger, run
from time import sleep

logger.setLevel(10)  # for debugging

def on_close(self, message, client):
    print(repr(client) + " : " + message)

def on_connect(client):
    print(repr(client) + " connected")

def on_message(message, client):
    print(repr(clent) + " : " + repr(message))
    try:
        client.send("you said: " + message)
        sleep(2)
        client.send("you said: " + message)

    except WebSocketError:
        pass

app = WSocketApp()
app.onconnect += on_connect
app.onmessage += on_message
app.onclose += on_close

run(app)

for more info on client see :-

pageWebsocket

WSocketApp

class  WSocketApp(
    app=None,
    protocol=None
)

app should be a valid WSGI web application.

protocol is websocket sub protocol to accept (ex: WAMP)

Class variables

GUID - unique ID to generate websocket accept key

SUPPORTED_VERSIONS - 13, 8 or 7

websocket_class - "wsgi.websocket" in WSGI Environ

Events

onconnect - fires when client sent a message

onmessage - fires when client sent a message onmessage - fires when client sent a message

you can attach event handler method to event using

• += operator

  app = WSocketApp()
  app.onmessage += on_message
  app.onmessage += on_message2
  # both `on_message` and `on_message2` can handle event
  run(app)

• + operator

  app = WSocketApp()
  app.onmessage + on_message
  app.onmessage + on_message2
  # both `on_message` and `on_message2` can handle event
  run(app)

• = operator

  app = WSocketApp()
  app.onmessage = on_message
  # only `on_message` can handle event
  app.onmessage = on_message2
  # now, only `on_message2` can handle event
  run(app)

You can't add new handlers to Event after = operator used. It replaces Event. But you can replace it again using another handler.
