(401) Unauthorized with python-firebase

[ultra909]

I am trying to update Firebase using the python-firebase library, but cannot get authentication to work, using some slightly adapted sample code:

from firebase import firebase as fb
auth = fb.FirebaseAuthentication('<firebase secret>', 'm...@gmail.com', auth_payload={'uid': '<uid>'}) // NB renamed extras -> auth_payload, id -> uid here
firebase = fb.FirebaseApplication('https://<url>.firebaseio.com', authentication=auth)
result = firebase.get('/users', name=None, connection=None, params={'print': 'pretty'}) // HTTPError: 401 Client Error: Unauthorized
print result

I keep getting (401) Unauthorized, but I notice that the token generated by the library is radically different to one generated by a JavaScript version of FirebaseTokenGenerator - and the latter authenticates fine when I provide the same URL, uid and secret.

I noticed a GitHub issue, questioning why the library did not just use the official Python firebase-token-generator, so I forked and implemented the suggested change just in case it would make a difference, but still get the same result.

Can anyone suggest what might be tripping me up here? Possible my Python crypto libraries setup is somehow incompatible (I am using Anaconda)?

Hi Jacob,

I looked at the so post but I dont understand your answer.  Im trying to authenticate a user as well so that I can fetch my data.  I dont know what the difference between these 2 methods that I found on the web is:

method A

auth = fb.FirebaseAuthentication('pwd', 'email', auth_payload="None")
firebase = fb.FirebaseApplication('https://stapp-48d1b.firebaseio.com', authentication=auth)

method B

def auth_with_password(self, email, password):
    request_ref = 'https://auth.firebase.com/auth/firebase?firebase={0}&email={1}&password={2}'.\
        format(self.fire_base_name, email, password)
    request_object = self.requests.get(request_ref)
    return request_object.json()

Please illustrate?  Thanks

The python-firebase library is not an official Firebase SDK. It is a third-party SDK which has not been updated since November of 2014. I would strongly urge you to either use the official REST API (API reference here and here) or a third-party SDK which is up-to-date like Pyrebase.

Cheers,

Jacob
