Jenkins HTTPS Basic Auth fails with Python 3.5

[Yen-wei Liu]

Hi,

I tried the example one from the document with python-jenkins 1.3.0 on Ubuntu 16.04.5 x64 with stock Python 3.5.2 with HTTPS and SSL cert verification disabled :

=====
import os
import jenkins
os.environ['PYTHONHTTPSVERIFY'] = "0"

server = jenkins.Jenkins('https://<my jenkins server>:8443/jenkins',
    username='user', password='password')

user = server.get_whoami()
version = server.get_version()

print('Hello %s from Jenkins %s' % (user['fullName'], version))
======

And I got this error:

jenkins.JenkinsException: Error in request. Possibly authentication failed [401]:

After digging into python-jenkins code, I found out this one at line 317 in __init__.py:

=====
if username is not None and password is not None:
    self._auths[0] = (
        'basic',
        requests.auth.HTTPBasicAuth(
            username.encode('utf-8'), password.encode('utf-8'))
    )
=====

the "encode('utf-8')" would make username and password binary strings and in requests.auth:

=====
def _basic_auth_str(username, password):
    """Returns a Basic Auth string."""

    authstr = 'Basic ' + to_native_string(
        b64encode(('%s:%s' % (username, password)).encode('latin1')).strip()
    )

    return authstr
=====
the parameter passed to b64encode() would become "b'user':b'password'" so the authentication would fail.

So far I remove encode('utf-8') in __init__.py so it would work. Just curious: is it my problem or how would this work with encode('utf-8') ?

OS: Ubuntu 16.04.5 X64
Python: 3.5.2 (stock)
Python-jenkins: 1.3.0
requests: 2.9.1

Thanks for your attention.

Has it ever been resolved somehow? So far this is the only solution I could find.

OS: Windows 10 1809
Python: 3.7.2
Python-jenkins: 1.5.0
Requests: 2.11.1
