28.1.4. File tools

28.1.4.1. Download file via HTTP(S)

Downloads a URL to the file system with an HTTP(S) GET or POST request.

Parameters

Basic parameters

Label	Name	Type	Description
URL	URL	[string]	The URL of the file to download.
File destination	OUTPUT	[string] Default: [Save to temporary file]	Specification of the file destination. One of: Save to a Temporary File Save to File…

Advanced parameters

Label	Name	Type	Description
Method	METHOD	[enumeration] Default: 0	The HTTP method to use for the request. Options are: 0 — GET 1 — POST
Data Optional	DATA	[string]	The data to add in the body if the request is a POST.

Outputs

Label	Name	Type	Description
File destination	OUTPUT	[string]	The location of the downloaded file

Python code

Algorithm ID: qgis:filedownloader

import processing
processing.run("algorithm_id", {parameter_dictionary})

The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. The parameter dictionary provides the parameter NAMEs and values. See Using processing algorithms from the console for details on how to run processing algorithms from the Python console.

28.1.4.2. HTTP(S) POST/GET request

Performs a HTTP(S) POST/GET request and returns the HTTP status code and the reply data. If an error occurs then the error code and the message will be returned. Optionally, the result can be written to a file on the disk. By default the algorithm will warn on errors. Optionally, the algorithm can be set to treat HTTP errors as failures.

Parameters

Label	Name	Type	Description
URL or file path	URL	[string]	The URL or path of the file to open.
Method	METHOD	[enumeration] Default: 0	The HTTP method to use for the request. Options are: 0 — GET 1 — POST
POST Data Optional	DATA	[string]	The data to add in the body if the request is a POST.
Authentication Optional	AUTH_CONFIG	[authconfig] Default: No authentication	An authentication configuration to pass
Consider HTTP errors as failures	FAIL_ON_ERROR	[boolean] Default: False	If set, the algorithm will fail on encountering an HTTP error.
File destination Optional	OUTPUT	[string] Default: [Skip Output]	The result can be written to a file instead of being returned as a string. Specification of the file destination. One of: Skip Output Save to a Temporary File Save to File…

Outputs

Label	Name	Type	Description
File destination	OUTPUT	[file]	The downloaded file with the returned result
HTTP Status	STATUS_CODE	[string]	The HTTP Status
Network error code	ERROR_CODE	[string]	The error code when it fails (like as well on 404 HTTP Status etc.)
Network error message	ERROR_MESSAGE	[string]	A string containing the error message in case of failure
Result data	RESULT_DATA	[string]	A string containing the result data in case of success

Python code

Algorithm ID: native:httprequest

import processing
processing.run("algorithm_id", {parameter_dictionary})

The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. The parameter dictionary provides the parameter NAMEs and values. See Using processing algorithms from the console for details on how to run processing algorithms from the Python console.

28.1.4.3. Open file or URL

Opens files in their default associated application, or URLs in the user’s default web browser.

Parameters

Label	Name	Type	Description
URL or file path	URL	[string]	The URL or path of the file to open.

Outputs

The algorithm has no output.

Python code

Algorithm ID: native:openurl
