            Basic/Digest/Custom HTTP Auth.
        :param timeout: (optional) How long to wait for the server to send
            data before giving up, as a float, or a :ref:`(connect timeout,
            read timeout) <timeouts>` tuple.
        :type timeout: float or tuple

            hostname to the URL of the proxy.
        :param stream: (optional) whether to immediately download the response
            content. Defaults to ``False``.
        :param verify: (optional) Either a boolean, in which case it controls whether we verify
            the server's TLS certificate, or a string, in which case it must be a path
            to a CA bundle to use. Defaults to ``True``. When set to
            ``False``, requests will accept any TLS certificate presented by
            the server, and will ignore hostname mismatches and/or expired
            certificates, which will make your application vulnerable to
            man-in-the-middle (MitM) attacks. Setting verify to ``False``
            may be useful during local development or testing.

        This method has been deprecated since version 1.0.0 and is only kept for
        backwards compatibility. New code should use :class:`~requests.sessions.Session`
        to create a session. This may be removed at a future date.
