Failure with cookie authentication patch required as workaround

[philippelt]

I am using streamlit-Authenticator which works almost fine except that cookie faster reauthentication never worked.

I am using streamline 1.20.0 and streamlit-authenticator 0.2.1 with python 3.10.6

I've done some analysis and found that the problem is in the module streamlit_authenticator/authenticate.pyat line #106.

The function call :

self.token = self.cookie_manager.get(self.cookie_name)

do NOT return the token value but return None (I checked that the browser effectively sent the cookie properly).

I replaced this line by:

allCookies = self.cookie_manager.get_all()
self.token = allCookies.get(self.cookie_name, None)

and then the correct token value is recovered and processed as expected allowing me to recover authentication.

Any idea why the get do not work ?

Hi @philippelt, thank you for checking this. What version of the cookies library are you using? Are you using extra_streamlit_components==0.1.55? This issue should not occur, and I can't really figure out why it is happening.

I am using streamline 1.20.0 and streamlit-authenticator 0.2.1 with python 3.10.6

The extra_streamlit_component automatically installed is 0.1.56

This behavior was consistent between Safari, Firefox and Chrome.

The Streamlit app is running on Ubuntu 22.04

The difference between the two methods is that get(...) is working on a local dictionary copy (self.cookies) of the cookies set at init of the CookieManagerclass wether get_all(...) is requesting the actual cookies from js cookie_manager.

Looks like the context of the class instance may be lost somewhere... But I am not familiar with streamlit components thus I don't understand the effect of the key parameter used to call js cookie_manager which is init in the initialization of the class and get_all for the get_all method. This is rather part of extra_streamlit_component.
