Rossion is a fast and simple session module for tornado app. It is distributed as a single file module and has dependencies on JUST pylibmc.
Here is a simple session supported example Tornado based web app for Rossion.
import tornado.ioloop
import tornado.web
import rossion.SessionMixin
import pylibmc
class MainHandler(tornado.web.RequestHandler, rossion.SessionMixin):
def get_current_user(self):
return self.session.get('user')
def get(self):
self.write("Hello, %s" % (self.current_user))
def post(self):
self.session['user'] = "Gromash"
self.finish()
def make_app():
return tornado.web.Application([
(r"/", MainHandler),
], engine="memcached", storage=self.__mc())
def __mc(self):
return pylibmc.Client([127.0.0.1:11211], binary=True,
behaviors={'no_block': True, 'tcp_nodelay': True,
'ketama': True})
if __name__ == "__main__":
app = make_app()
app.listen(8888)
tornado.ioloop.IOLoop.current().start()Or use engine='memory', storage={} instead of memcached backend session.
Install the latest stable release with pip install rossion or download rossion.py into your project directory with pylibmc preinstalled.
