Base64 Authentication Python

Question

I\'m following an api and I need to use a Base64 authentication of my User Id and password.

\'User ID and Password need to both be concatenated and then Base64 encoded\'

Answer 1

The requests library has Basic Auth support and will encode it for you automatically. You can test it out by running the following in a python repl

from requests.auth import HTTPBasicAuth
r = requests.post(api_URL, auth=HTTPBasicAuth('user', 'pass'), data=payload)

You can confirm this encoding by typing the following.

r.request.headers['Authorization']

outputs:

u'Basic c2RhZG1pbmlzdHJhdG9yOiFTRG0wMDY4'

Answer 2

With python3, I have found a solution which is working for me:

import base64
userpass = username + ':' + password
encoded_u = base64.b64encode(userpass.encode()).decode()
headers = {"Authorization" : "Basic %s" % encoded_u}

Answer 3

As explained in the Requests documentation https://2.python-requests.org/en/latest/user/authentication/

Making requests with HTTP Basic Auth is very simple:

>>> from requests.auth import HTTPBasicAuth
>>> requests.get('https://api.github.com/user', auth=HTTPBasicAuth('user', 'pass'))
<Response [200]>

In fact, HTTP Basic Auth is so common that Requests provides a handy shorthand for using it:

>>> requests.get('https://api.github.com/user', auth=('user', 'pass'))
<Response [200]>

Providing the credentials in a tuple like this is exactly the same as the HTTPBasicAuth example above.

Answer 4

You can encode the data and make the request by doing the following:

import requests, base64

usrPass = "userid:password"
b64Val = base64.b64encode(usrPass)
r=requests.post(api_URL, 
                headers={"Authorization": "Basic %s" % b64Val},
                data=payload)

I'm not sure if you've to add the "BASIC" word in the Authorization field or not. If you provide the API link, It'd be more clear.
