   Bases: :class:`airflow.hooks.base_hook.BaseHook`

   Interact with HTTP servers.

   :param http_conn_id: connection that has the base API url i.e https://www.google.com/
       and optional authentication credentials. Default headers can also be specified in
       the Extra field in json format.
   :type http_conn_id: str
   :param method: the API method to be called
   :type method: str

   
   .. method:: get_conn(self, headers=None)

      Returns http session for use with requests

      :param headers: additional headers to be passed through as a dictionary
      :type headers: dict



   
   .. method:: run(self, endpoint, data=None, headers=None, extra_options=None)

      Performs the request

      :param endpoint: the endpoint to be called i.e. resource/v1/query?
      :type endpoint: str
      :param data: payload to be uploaded or request parameters
      :type data: dict
      :param headers: additional headers to be passed through as a dictionary
      :type headers: dict
      :param extra_options: additional options to be used when executing the request
          i.e. {'check_response': False} to avoid checking raising exceptions on non
          2XX or 3XX status codes
      :type extra_options: dict



   
   .. method:: check_response(self, response)

      Checks the status code and raise an AirflowException exception on non 2XX or 3XX
      status codes

      :param response: A requests response object
      :type response: requests.response



   
   .. method:: run_and_check(self, session, prepped_request, extra_options)

      Grabs extra options like timeout and actually runs the request,
      checking for the result

      :param session: the session to be used to execute the request
      :type session: requests.Session
      :param prepped_request: the prepared request generated in run()
      :type prepped_request: session.prepare_request
      :param extra_options: additional options to be used when executing the request
          i.e. {'check_response': False} to avoid checking raising exceptions on non 2XX

      :type extra_options: dict



   
   .. method:: run_with_advanced_retry(self, _retry_args, *args, **kwargs)

      Runs Hook.run() with a Tenacity decorator attached to it. This is useful for
      connectors which might be disturbed by intermittent issues and should not
      instantly fail.

      :param _retry_args: Arguments which define the retry behaviour.
          See Tenacity documentation at https://github.com/jd/tenacity
