How to use beaker in tornado?

1. Install Beaker: Make sure you have Beaker installed. You can install it using pip:

   pip install beaker
   

2. Import required modules: In your Tornado application, import the necessary modules for Beaker and Tornado:

   from beaker.middleware import SessionMiddleware
   import tornado.ioloop
   import tornado.web
   

3. Configure Beaker middleware: Create a session configuration dictionary for Beaker and set up the middleware. You can define this dictionary with various options to customize the session behavior, such as the session type, storage options, expiration time, etc.

   session_config = {
       'session.type': 'file',
       'session.data_dir': './session_data',
       'session.cookie_expires': True,
       'session.auto': True,
   }
   

4. Create your Tornado application and wrap it with Beaker middleware: Wrap your Tornado application with the Beaker middleware to enable session management.

   class MainHandler(tornado.web.RequestHandler):
       def get(self):
           # Access the session using self.request.environ['beaker.session']
           session = self.request.environ['beaker.session']
           # Now you can use the session like a dictionary, e.g., session['key'] = value
           # ...
   
   app = tornado.web.Application([
       (r"/", MainHandler),
   ])
   
   app = SessionMiddleware(app, session_config)
   

5. Start the Tornado server: Start the Tornado server as usual with tornado.ioloop.IOLoop.current().start().

With these steps, your Tornado application is now integrated with Beaker, and you can use sessions by accessing self.request.environ['beaker.session'] inside your Tornado request handlers.

Remember to configure Beaker according to your specific requirements, like choosing the session storage type (file, database, etc.), setting expiration times, etc., as mentioned in the session_config dictionary.
