reason

Reason for restoring.

Default: (empty)
tags

Change tags to apply to the entry in the deletion log.

Values (separate with | or alternative): possible vandalism, repeating characters
timestamps

Timestamps of the revisions to restore. If both timestamps and fileids are empty, all will be restored.

Type: list of timestamps (allowed formats)
Separate values with | or alternative.
Maximum number of values is 50 (500 for clients allowed higher limits).

IDs of the file revisions to restore. If both timestamps and fileids are empty, all will be restored.

Type: list of integers
Separate values with | or alternative.
Maximum number of values is 50 (500 for clients allowed higher limits).

Unconditionally add or remove the page from the current user's watchlist, use preferences (ignored for bot users) or do not change watch.

One of the following values: nochange, preferences, unwatch, watch
Default: preferences

Ejemplo

Recuperar las revisiones de una página es un proceso de varios pasos:

  1. Inicia sesión, a través de uno de los métodos descritos en API:Login .
  2. GET un CSRF token . Este token es el mismo para todas las páginas, pero cambia en cada inicio de sesión.
  3. Envía una solicitud POST con el token CSRF para recuperar.

El código de muestra, abajo, cubre el tercer paso en detalle.

Solicitud POST

Restaura dos revisiones de Sandbox/Test.
