  8. ===========

  10. A node with the ability to send HTTP(S) requests.
  11. .. rst-class:: classref-introduction-group
  12. Description
  13. -----------
  14. A node with the ability to send HTTP requests. Uses :ref:`HTTPClient<class_HTTPClient>` internally.
  15. Can be used to make HTTP requests, i.e. download or upload files or web content via HTTP.
  16. \ **Warning:** See the notes and warnings on :ref:`HTTPClient<class_HTTPClient>` for limitations, especially regarding TLS security.
  17. \ **Note:** When exporting to Android, make sure to enable the ``INTERNET`` permission in the Android export preset before exporting the project or using one-click deploy. Otherwise, network communication of any kind will be blocked by Android.
  18. \ **Example:** Contact a REST API and print one of its returned fields:
  19. .. tabs::
  20. .. code-tab:: gdscript
  21. func _ready():
  22. # Create an HTTP request node and connect its completion signal.

  137. \ **Note:** **HTTPRequest** nodes will automatically handle decompression of response bodies. A ``Accept-Encoding`` header will be automatically added to each of your requests, unless one is already specified. Any response with a ``Content-Encoding: gzip`` header will automatically be decompressed and delivered to you as uncompressed bytes.

  272. Any Response body declaring a ``Content-Encoding`` of either ``gzip`` or ``deflate`` will then be automatically decompressed, and the uncompressed bytes will be delivered via :ref:`request_completed<class_HTTPRequest_signal_request_completed>`.
  273. If the user has specified their own ``Accept-Encoding`` header, then no header will be added regardless of :ref:`accept_gzip<class_HTTPRequest_property_accept_gzip>`.
  274. If ``false`` no header will be added, and no decompression will be performed on response bodies. The raw bytes of the response body will be returned via :ref:`request_completed<class_HTTPRequest_signal_request_completed>`.

  320. The duration to wait in seconds before a request times out. If :ref:`timeout<class_HTTPRequest_property_timeout>` is set to ``0.0`` then the request will never time out. For simple requests, such as communication with a REST API, it is recommended that :ref:`timeout<class_HTTPRequest_property_timeout>` is set to a value suitable for the server response time (e.g. between ``1.0`` and ``10.0``). This will help prevent unwanted timeouts caused by variation in server response times while still allowing the application to detect when a request has timed out. For larger requests such as file downloads it is suggested the :ref:`timeout<class_HTTPRequest_property_timeout>` be set to ``0.0``, disabling the timeout functionality. This will help to prevent large transfers from failing due to exceeding the timeout value.

  365. \ **Note:** When ``method`` is :ref:`HTTPClient.METHOD_GET<class_HTTPClient_constant_METHOD_GET>`, the payload sent via ``request_data`` might be ignored by the server or even cause the server to reject the request (check `RFC 7231 section 4.3.1 <https://datatracker.ietf.org/doc/html/rfc7231#section-4.3.1>`__ for more details). As a workaround, you can send data as a query string in the URL (see :ref:`String.uri_encode()<class_String_method_uri_encode>` for an example).
  366. \ **Note:** It's recommended to use transport encryption (TLS) and to avoid sending sensitive information (such as login credentials) in HTTP GET URL parameters. Consider using HTTP POST requests or HTTP headers for such information instead.
