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. :param cert: (optional) if String, path to ssl client cert file (.pem).
