Source: MediaWiki
License: GPL-2.0-or-later

https://www.mediawiki.org/wiki/Special:MyLanguage/API:Options

Specific parameters:

Other general parameters are available.

reset

Resets preferences to the site defaults.

Type: boolean (details)

resetkinds

List of types of options to reset when the reset option is set.

Values (separate with | or alternative): all, registered, registered-checkmatrix, registered-multiselect, special, unused, userjs

Default: all

change

List of changes, formatted name=value (e.g. skin=vector). If no value is given (not even an equals sign), e.g., optionname|otheroption|..., the option will be reset to its default value. If any value passed contains the pipe character (|), use the alternative multiple-value separator for correct operation.

Separate values with | or alternative.

Maximum number of values is 50 (500 for clients that are allowed higher limits).

optionname

The name of the option that should be set to the value given by optionvalue.

optionvalue

The value for the option specified by optionname. When optionname is set but optionvalue is omitted, the option will be reset to its default value.

global

What to do if the option was set globally using the GlobalPreferences extension.

ignore: Do nothing. The option remains with its previous value.
override: Add a local override.
update: Update the option globally.

One of the following values: ignore, override, update

Default: ignore

token

A "csrf" token retrieved from action=query&meta=tokens

This parameter is required.

Examples:

Reset all preferences.: api.php?action=options&reset=&token=123ABC [open in sandbox]
Change skin and hideminor preferences.: api.php?action=options&change=skin=vector|hideminor=1&token=123ABC [open in sandbox]
Reset all preferences, then set skin and nickname.: api.php?action=options&reset=&change=skin=monobook&optionname=nickname&optionvalue=[[User:Beau|Beau]]%20([[User_talk:Beau|talk]])&token=123ABC [open in sandbox]

Przykład

Making any POST request is a multi-step process:

Log in, via one of the methods described on API:Logowanie .
Get an Edit token .
api.php?action=query&format=json&meta=tokens [wypróbuj w ApiSandbox]
Send a POST request, with the CSRF token, to take action on a page.

The sample code below covers the final step in detail.

Żądanie POST

In this example, all parameters are passed in a GET request for the sake of simplicity. However, action=options requires POST requests; GET requests will cause an error.

Changing three options

api.php?action=options&token=58b54e0bab4a1d3fd3f7653af38e75cb%2B\&change=hideminor=1|skin=vector&optionname=nickname&optionvalue=custom-signa|ture [wypróbuj w ApiSandbox]

Wynik

Dodatkowe informacje

This API is primarily intended for changing options which are registered by MediaWiki core or extensions and available on Special:Preferences.
You can also use the API to set arbitrary user options that can be used by user scripts or external editors. These options must begin with the prefix userjs-.
There is currently no limit on the number of user options you can set at once. You can store data within a user option by encoding it as a JSON string.
Providing only names of options without equal sign results in resetting them (e.g. hideminor|skin). In the case of an arbitrary userjs- key/value pair, the resetting results in its deletion.
The change parameter cannot be used to set a value which contains a pipe character |, as it is used by the API to separate options. If you need to set such a value (e.g., a user signature) use an optionname & optionvalue pair.
The following limits apply to all user options:
- The byte length of the key must be <= 255.
- The byte length of the value must be <= 65535.
- The key must consist only of ASCII letters, numbers, hyphens and underscores (a-z, A-Z, 0-9, _, -).
