HTTP Connection
===============

The HTTP connection enables connections to HTTP services.

Authenticating with HTTP
------------------------

Login and Password authentication can be used along with any authentication method using headers.
Headers can be given in json format in the Extras field.

Default Connection IDs
----------------------

The HTTP operators and hooks use ``http_default`` by default.

Configuring the Connection
--------------------------

Login (optional)
    Specify the login for the http service you would like to connect too.

Password (optional)
    Specify the password for the http service you would like to connect too.

Host (optional)
    Specify the entire url or the base of the url for the service.

Port (optional)
    Specify a port number if applicable.

Schema (optional)
    Specify the service type etc: http/https.

Extras (optional)
    Specify headers in json format.

When specifying the connection in environment variable you should specify
it using URI syntax.

Note that all components of the URI should be URL-encoded.

For example:

.. code-block:: bash

   export AIRFLOW_CONN_HTTP_DEFAULT='http://username:password@servvice.com:80/https?headers=header'
