Brief Description

A node with the ability to send HTTP requests.

void	cancel_request ( )
int	get_body_size ( ) const
int	get_downloaded_bytes ( ) const
Status	get_http_client_status ( ) const
Error	request ( String url, PoolStringArray custom_headers=PoolStringArray( ), bool ssl_validate_domain=true, Method method=0, String request_data=”” )

request_completed ( int result, int response_code, PoolStringArray headers, PoolByteArray body )

This signal is emitted upon request completion.

enum Result:

RESULT_SUCCESS = 0 — Request successful.
RESULT_CHUNKED_BODY_SIZE_MISMATCH = 1
RESULT_CANT_CONNECT = 2 — Request failed while connecting.
RESULT_CANT_RESOLVE = 3 — Request failed while resolving.
RESULT_CONNECTION_ERROR = 4 — Request failed due to connection (read/write) error.
RESULT_SSL_HANDSHAKE_ERROR = 5 — Request failed on SSL handshake.
RESULT_NO_RESPONSE = 6 — Request does not have a response (yet).
RESULT_BODY_SIZE_LIMIT_EXCEEDED = 7 — Request exceeded its maximum size limit, see body_size_limit.
RESULT_REQUEST_FAILED = 8 — Request failed. (Unused)
RESULT_DOWNLOAD_FILE_CANT_OPEN = 9 — HTTPRequest couldn’t open the download file.
RESULT_DOWNLOAD_FILE_WRITE_ERROR = 10 — HTTPRequest couldn’t write to the download file.
RESULT_REDIRECT_LIMIT_REACHED = 11 — Request reached its maximum redirect limit, see max_redirects.

A node with the ability to send HTTP requests. Uses HTTPClient internally.

Can be used to make HTTP requests, i.e. download or upload files or web content via HTTP.

Setter	set_body_size_limit(value)
Getter	get_body_size_limit()

Maximum allowed size for response bodies.

Setter	set_download_file(value)
Getter	get_download_file()

The file to download into. Will output any received file into it.

Setter	set_max_redirects(value)
Getter	get_max_redirects()

Maximum number of allowed redirects.

Setter	set_use_threads(value)
Getter	is_using_threads()

If true, multithreading is used to improve performance.

Cancels the current request.

Returns the response body length.

Returns the amount of bytes this HTTPRequest downloaded.

Returns the current status of the underlying HTTPClient. See STATUS_* enum on HTTPClient.

Error request ( String url, PoolStringArray custom_headers=PoolStringArray( ), bool ssl_validate_domain=true, Method method=0, String request_data=”” )

Creates request on the underlying HTTPClient. If there is no configuration errors, it tries to connect using HTTPClient.connect_to_host and passes parameters onto HTTPClient.request.

Returns @GlobalScope.OK if request is successfully created. (Does not imply that the server has responded), @GlobalScope.ERR_UNCONFIGURED if not in the tree, @GlobalScope.ERR_BUSY if still processing previous request, @GlobalScope.ERR_INVALID_PARAMETER if given string is not a valid URL format, or @GlobalScope.ERR_CANT_CONNECT if not using thread and the HTTPClient cannot connect to host.
