  115. -------------------
  116. .. _class_HTTPRequest_method_cancel_request:
  117. - void **cancel_request** **(** **)**
  118. Cancels the current request.
  119. ----
  120. .. _class_HTTPRequest_method_get_body_size:
  121. - :ref:`int<class_int>` **get_body_size** **(** **)** const
  122. Returns the response body length.
  123. ----
  124. .. _class_HTTPRequest_method_get_downloaded_bytes:
  125. - :ref:`int<class_int>` **get_downloaded_bytes** **(** **)** const
  126. Returns the amount of bytes this HTTPRequest downloaded.
  127. ----
  128. .. _class_HTTPRequest_method_get_http_client_status:
  129. - :ref:`Status<enum_HTTPClient_Status>` **get_http_client_status** **(** **)** const
  130. Returns the current status of the underlying :ref:`HTTPClient<class_HTTPClient>`. See ``STATUS_*`` enum on :ref:`HTTPClient<class_HTTPClient>`.
  131. ----
  132. .. _class_HTTPRequest_method_request:

  134. Creates request on the underlying :ref:`HTTPClient<class_HTTPClient>`. If there is no configuration errors, it tries to connect using :ref:`HTTPClient.connect_to_host<class_HTTPClient_method_connect_to_host>` and passes parameters onto :ref:`HTTPClient.request<class_HTTPClient_method_request>`.
  135. Returns :ref:`@GlobalScope.OK<class_@GlobalScope_constant_OK>` if request is successfully created. (Does not imply that the server has responded), :ref:`@GlobalScope.ERR_UNCONFIGURED<class_@GlobalScope_constant_ERR_UNCONFIGURED>` if not in the tree, :ref:`@GlobalScope.ERR_BUSY<class_@GlobalScope_constant_ERR_BUSY>` if still processing previous request, :ref:`@GlobalScope.ERR_INVALID_PARAMETER<class_@GlobalScope_constant_ERR_INVALID_PARAMETER>` if given string is not a valid URL format, or :ref:`@GlobalScope.ERR_CANT_CONNECT<class_@GlobalScope_constant_ERR_CANT_CONNECT>` if not using thread and the :ref:`HTTPClient<class_HTTPClient>` cannot connect to host.
