TypeError: a bytes-like object is required, not 'str' when using REST in Python 3.5.1

Question

I am getting the following error when I run my Python REST API script:

Traceback (most recent call last):
  File "api_tufin_4.py", line 4, in <module>
    b64Val = base64.b64encode(usrPass)
  File "C:\Program Files\Python35\lib\base64.py", line 62, in b64encode
    encoded = binascii.b2a_base64(s)[:-1]
TypeError: a bytes-like object is required, not 'str'

I am using the following code:

import requests, base64

usrPass = "user:pass"
b64Val = base64.b64encode(usrPass)
api_URL = 'api-url'
r=requests.post(api_URL, 
                headers={"Authorization": "Basic %s" % b64Val},
                data=payload)

Please take a look at the docs.

base64.b64encode works on binary data (bytes), not text data (str).

Make your username/password a bytes literal and you're fine. If it's ASCII, the translation is trivial:

usrPass = "user:pass"

becomes:

usrPass = b"user:pass"

The leading b makes it a bytes literal.
