prat-geventwebsocket 0.3.7 (beta)

Prat fork of Jeffrey Gelen's gevent Websocket handler

Gevent Server

At the moment gevent-websocket has one handler based on the Pywsgi gevent Hook up the WebSocketHandler to the Pywsgi Server by setting the handler_class when creating the server instance.

from gevent import pywsgi
from geventwebsocket.handler import WebSocketHandler

server = pywsgi.WSGIServer(("", 8000), websocket_app,
    handler_class=WebSocketHandler)
server.serve_forever()

The handler enhances your WSGI app with a Websocket environment variable when the browser requests a Websocket connection.

def websocket_app(environ, start_response):
    if environ["PATH_INFO"] == '/echo':
        ws = environ["wsgi.websocket"]
        message = ws.receive()
        ws.send(message)

Gunicorn Server

Using Gunicorn it is even more easy to start a server. Only the websocket_app from the previous example is required to start the server. Start Gunicorn using the following command and worker class to enable Websocket funtionality for the application.

gunicorn -k "geventwebsocket.gunicorn.workers.GeventWebSocketWorker" wsgi:websocket_app
