.. py:class:: HttpSensor(*, endpoint, http_conn_id = 'http_default', method = 'GET', request_params = None, headers = None, response_check = None, extra_options = None, **kwargs)

   Bases: :py:obj:`airflow.sensors.base.BaseSensorOperator`

   Executes a HTTP GET statement and returns False on failure caused by
   404 Not Found or `response_check` returning False.

   HTTP Error codes other than 404 (like 403) or Connection Refused Error
   would raise an exception and fail the sensor itself directly (no more poking).
   To avoid failing the task for other codes than 404, the argument ``extra_option``
   can be passed with the value ``{'check_response': False}``. It will make the ``response_check``
   be execute for any http status code.

   The response check can access the template context to the operator:

       def response_check(response, task_instance):
           # The task_instance is injected, so you can pull data form xcom
           # Other context variables such as dag, ds, execution_date are also available.
           xcom_data = task_instance.xcom_pull(task_ids='pushing_task')
           # In practice you would do something more sensible with this data..
           print(xcom_data)
           return True

       HttpSensor(task_id='my_http_sensor', ..., response_check=response_check)

       For more information on how to use this operator, take a look at the guide:
       :ref:`howto/operator:HttpSensor`

   :param http_conn_id: The :ref:`http connection<howto/connection:http>` to run the
       sensor against
   :param method: The HTTP request method to use
   :param endpoint: The relative part of the full url
   :param request_params: The parameters to be added to the GET url
   :param headers: The HTTP headers to be added to the GET request
   :param response_check: A check against the 'requests' response object.
       The callable takes the response object as the first positional argument
       and optionally any number of keyword arguments available in the context dictionary.
       It should return True for 'pass' and False otherwise.
   :param extra_options: Extra options for the 'requests' library, see the
       'requests' documentation (options to modify timeout, ssl, etc.)

      Function that the sensors defined while deriving this class should
      override.
