API:Allredirects

From mediawiki.org
MediaWiki version:
1.23

GET request to list all redirects. All filters available with this API affect the redirect targets and not the redirect sources.

This module can be used as a generator . When used as a generator, the titles used for the generator are from the redirect sources instead of the redirect targets, unless the garunique parameter is used.

fragment

interwiki
Adds the interwiki prefix from the redirect, if any (cannot be used with arunique).
Values (separate with | or alternative): fragment, ids, interwiki, title
Default: title
arnamespace

The namespace to enumerate.

One of the following values: -1, -2, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 90, 91, 92, 93, 100, 101, 102, 103, 104, 105, 106, 107, 486, 487, 710, 711, 828, 829, 1198, 1199, 2600, 5500, 5501
Default: 0
arlimit

How many total items to return.

Type: integer or max
The value must be between 1 and 500.
Default: 10
ardir

The direction in which to list.

One of the following values: ascending, descending
Default: ascending
Examples:
List target pages, including missing ones, with page IDs they are from, starting at B.
api.php?action=query&list=allredirects&arfrom=B&arprop=ids|title [open in sandbox]
List unique target pages.
api.php?action=query&list=allredirects&arunique=&arfrom=B [open in sandbox]
Gets all target pages, marking the missing ones.
api.php?action=query&generator=allredirects&garunique=&garfrom=B [open in sandbox]
Gets pages containing the redirects.
api.php?action=query&generator=allredirects&garfrom=B [open in sandbox]

The arfrom, arto and arprefix input parameters filter by the target redirect title without namespace. A namespace must not be added to those parameters, otherwise the API returns an invalidtitle error. This means those parameters effectively filter titles in the main namespace, unless a different namespace is selected by the arnamespace parameter, which would affect titles in that namespace.

Example[edit]

GET request[edit]

Get the first three unique pages containing redirects to the main namespace.


Response[edit]

Both the title and namespace returned refer to the redirect target and not the redirect itself.
