Torndsession is a session extension for Tornado web framework. Torndsession support application memory, file, redis or memcached to save session data for request, and it's easy to extend for developer.
Here is a simple "Hello, Session" example web app for Tornado with Torndsession.:
import tornado.web import tornado.httpserver import tornado.ioloop import torndosession class Application(tornado.web.Application): def __init__(self): handlers = [ (r"/", MainHandler), ] settings = dict( debug = True, ) tornado.web.Application.__init__(self, handlers, **settings) class MainHandler(torndsession.sessionhandler.SessionBaseHandler): def get(self): self.write("Hello, Session.<br/>") if 'data' in self.session: data = self.session['data'] else: data = 0 self.write('data=%s' % data) self.session["data"] = data + 1 def main(): http_server = tornado.httpserver.HTTPServer(Application()) http_server.listen(8000) tornado.ioloop.IOLoop.instance().start() if __name__ == "__main__": main()
In this example, Request handler obtain memory session feature, it just inherit from SessionBaseHandler. more session example see torndsession demos.
