TypeError: bytes required, not 'str', when feed includes url authentication

[samuelclay]

Here's a simple testcase for the feed url https://username:password@example.com/feed/:

>>> import feedparser
>>> fp = feedparser.parse("https://username:password@example.com/feed/")
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/usr/local/lib/python3.9/site-packages/feedparser/api.py", line 214, in parse
    data = _open_resource(url_file_stream_or_string, etag, modified, agent, referrer, handlers, request_headers, result)
  File "/usr/local/lib/python3.9/site-packages/feedparser/api.py", line 114, in _open_resource
    return http.get(url_file_stream_or_string, etag, modified, agent, referrer, handlers, request_headers, result)
  File "/usr/local/lib/python3.9/site-packages/feedparser/http.py", line 148, in get
    auth = base64.standard_b64encode(f'{url_pieces.username}:{url_pieces.password}').strip()
  File "/usr/local/lib/python3.9/base64.py", line 95, in standard_b64encode
    return b64encode(s)
  File "/usr/local/lib/python3.9/base64.py", line 58, in b64encode
    encoded = binascii.b2a_base64(s, newline=False)
TypeError: a bytes-like object is required, not 'str'
>>> feedparser.__version__
'6.0.2'

I figured basic http url authentication is supported, but that may not be the case?

Found support in the documentation: https://feedparser.readthedocs.io/en/latest/http-authentication.html

@samuelclay How did you resolve this issue?
The documentation you linked at gives you two possiblities. Either in the way you described it in your first post which is not working or by using urllib2.
I have the same issue, but the urllib2 examples doesn't work for me as I am using Python 3 and have only urllib3 available.

PR #234 would fix it.

Samuel, thanks for reporting this. This is fixed in feedparser 6.0.5 thanks to @auouymous' PR.
