如何在浏览器上使用python-django实现自动注销

Question

I have a use case where I want the user to get logged out when they close their browser. And next time when the user visit the website, the user should be redirected to landing page / login page of my application.

From my side, I have implemented the following in django settings.py file:

SESSION_EXPIRE_AT_BROWSER_CLOSE = True
SESSION_COOKIE_AGE = 40  
SESSION_SAVE_EVERY_REQUEST = True
LOGOUT_REDIRECT_URL = '/logout_user/'

But this not helping. Any idea how to achieve this scenario?

Answer 1

The setting SESSION_EXPIRE_AT_BROWSER_CLOSE suggests to the users browser that it should discard the cookie once the browser is closed (they are called "non-persistend cookies").

But this cannot be enforced from the server; for example, there are browser extensions that allow you to keep the cookies even though they non-persistent. This warning can also be found in the django session docs .

The only sure way I know is to set an expiration date for the session (like you are doing with the setting SESSION_COOKIE_AGE ).

EDIT: this question suggests using a timestamp to check for session inactivity; maybe there are a few useful ideas for you.
