requests_toolbelt.auth.handler
==============================

This holds all of the implementation details of the Authentication Handler.

"""

from requests.auth import AuthBase, HTTPBasicAuth
from requests.compat import urlparse, urlunparse


class AuthHandler(AuthBase):

    """

    The ``AuthHandler`` object takes a dictionary of domains paired with
    authentication strategies and will use this to determine which credentials
    to use when making a request. For example, you could do the following:

    .. code-block:: python

        from requests import HTTPDigestAuth
        from requests_toolbelt.auth.handler import AuthHandler

        import requests

        auth = AuthHandler({
            'https://api.github.com': ('sigmavirus24', 'fakepassword'),
            'https://example.com': HTTPDigestAuth('username', 'password')
        })

        r = requests.get('https://api.github.com/user', auth=auth)
        # => <Response [200]>
        r = requests.get('https://example.com/some/path', auth=auth)
        # => <Response [200]>

        s = requests.Session()
        s.auth = auth
        r = s.get('https://api.github.com/user')
        # => <Response [200]>

    .. warning::

        :class:`requests.auth.HTTPDigestAuth` is not yet thread-safe. If you
        use :class:`AuthHandler` across multiple threads you should
        instantiate a new AuthHandler for each thread with a new
        HTTPDigestAuth instance for each thread.
