action=undelete(main | undelete)
Undelete revisions of a deleted page. A list of deleted revisions (including timestamps) can be retrieved through prop=deletedrevisions, and a list of deleted file IDs can be retrieved through list=filearchive. Specific parameters: Other general parameters are available.
|
Przykład
Undeleting the revisions of a page is a multi-step process:
- Log in using one of the methods described in API:Logowanie.
- Get a CSRF token. This token is the same for all pages but changes at every login.
- Send a POST request with the CSRF token in order to undelete.
The sample code below covers the third step in detail.
Żądanie POST
Restore two revisions of Sandbox/Test.
