How do I clear a flask session?

Question

While importing flask, we import modules such as session etc.

SecureCookieSession is a kind of dictionary, that can be accessed using session.

Now, I try to clear all the junk variables that I used while trying to build a website.

One of the answers on stackoverflow used a command like session.clear() for clearing the contents of a session. But such a command gives an error that no such command exists.

Can anyone point out for me how to clear the SecureCookieSession and how to clear the session every time I shutdown the server or close the website?

Answer 1

from flask import session

session.clear()

I use session like this with flask, it does work. I don't use SecureCookieSession though, but maybe it can help.

Answer 2

You can also iterate through the session and call session.pop() for each key in your session. Pop will remove the variable from the session and you don't have to keep updating your secret key.

for key in list(session.keys()):
     session.pop(key)
