librus_apix.exceptions.TokenError: Malformed or expired token

[anetczuk]

Hello,
I recently receive following exception when trying to get content of librus:

  File "/home/<user>/.local/lib/python3.12/site-packages/librus_apix/grades.py", line 158, in get_grades
    tr = no_access_check(
         ^^^^^^^^^^^^^^^^
  File "/home/<user>/.local/lib/python3.12/site-packages/librus_apix/helpers.py", line 19, in no_access_check
    raise TokenError("Malformed or expired token.")
librus_apix.exceptions.TokenError: Malformed or expired token.

I happens after successful authentication:

client = new_client()
client.get_token(username, password)
get_grades(client)     # exception goes here

Tried running pytest with received token and got following results: 21 failed, 4 passed, 4 errors.
Every fail/error is caused by Malformed or expired token..

Is there recent change in Librus portal related to authentication? How can I debug or investigate the problem?

@anetczuk Hey, yeah recently they must have changed something in the authentication process. If you login manually through their site and copy the DZIENNIKSID and SDZIENNIKSID headers into the token "DZIENNIKS:SDZIENNIKS" everything seems to function correctly.
Recently, I didn't have time to look into it further, if you need fix ASAP, you can check Network tab in the browser developer tools during login flow and see what's changed opposed to get_token function in client.py.

I've tried this approach (copying the token from browser) but does not work in my case. Have notices that in the browser every (almost?) request ends with 200 code, but in case of library there are couple of 302 responses. Maybe this makes the difference?

#66 Fixes this issue.
They changed something with the auth flow. I will merge after a bit more testing but pytest passed for me

I've tried this approach (copying the token from browser) but does not work in my case.

from librus_apix.client import new_client, Token
c = new_client()
c.token = Token(dzienniks=dzienniks, sdzienniks=sdzienniks)

This should work
