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 torndsession
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.
