Thanks for this library.
When trying to auth against the CZDS service I run into a Python exception: binascii.Error: Incorrect padding
(even if www.base64decode.org did decode my JWT base64 string just fine into JSON).
I'm not a pro in Python or this way of authentication at all, but at least padding the base64 string with ==
made the code work for me.
I patched https://github.com/mdiez/pyCZDS/blob/main/src/pyczds/authentication.py#L33
+ s = base64.b64decode(payload_b64)
- s = base64.b64decode(f"{payload_b64}==")
I can make a pull request if you prefer, but I'm not sure my hack is the right solution - let me know.
Hi,
You should fix padding also in _get_token_jwt_payload in authentication.py
File "/usr/local/lib/python3.10/dist-packages/pyczds/client.py", line 26, in _do_request
if not self._is_authenticated():
File "/usr/local/lib/python3.10/dist-packages/pyczds/authentication.py", line 44, in _is_authenticated
j = self._get_token_jwt_payload()
File "/usr/local/lib/python3.10/dist-packages/pyczds/authentication.py", line 33, in _get_token_jwt_payload
s = base64.b64decode(payload_b64)
File "/usr/lib/python3.10/base64.py", line 87, in b64decode
return binascii.a2b_base64(s)
binascii.Error: Incorrect padding
after I change it to
s = base64.b64decode(payload_b64 + '=' * (-len(payload_b64) % 4))
it works flawlessly
