|
gevent-websocket is a WebSocket library for the gevent networking library.
Features include:
Integration on both socket level or using an abstract interface.
RPC and PubSub framework using WAMP (WebSocket Application Messaging Protocol).
Easily extendible using a simple WebSocket protocol plugin API
from geventwebsocket import WebSocketServer, WebSocketApplication, Resource
class EchoApplication(WebSocketApplication):
def on_open(self):
print "Connection opened"
def on_message(self, message):
self.ws.send(message)
def on_close(self, reason):
print reason
WebSocketServer(
('', 8000),
Resource({'/': EchoApplication})
).serve_forever()
or a low level implementation:
from gevent import pywsgi
from geventwebsocket.handler import WebSocketHandler
def websocket_app(environ, start_response):
if environ["PATH_INFO"] == '/echo':
ws = environ["wsgi.websocket"]
message = ws.receive()
ws.send(message)
server = pywsgi.WSGIServer(("", 8000), websocket_app,
handler_class=WebSocketHandler)
server.serve_forever()
More examples can be found in the examples directory. Hopefully more documentation will be available soon.
Installation
The easiest way to install gevent-websocket is directly from PyPi using pip or setuptools by running the commands below:
$ pip install gevent-websocket
Gunicorn Worker
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
Performance
gevent-websocket is pretty fast, but can be accelerated further by installing wsaccel and ujson or simplejson:
$ pip install wsaccel ujson
gevent-websocket automatically detects wsaccell and uses the Cython implementation for UTF8 validation and later also frame masking and demasking.
