POST request to revert the last series of edits made by one user to a given page.
此功能与历史界面中提供的rollback链接效果是一样的。
API帮助文档
示例
发出任何POST请求都是一个多步骤的过程：
- 使用API:登录中描述的方法之一登录。
- 获取CSRF令牌。
- Send a POST request, with the CSRF token, to take action on a page and in this process gain
editpagerights to the given page: - GET a rollback token:
- If your wiki is using MediaWiki 1.24+, follow these instructions:
- Rollback tokens aren't universal: they are not only different for every login, but also depend on the title of the page and the name of the user whose edits are to be rolled back. 对于MediaWiki 1.23及之前的版本，可以通过如下的步骤：
POST请求
Send a POST request, with a rollback token to revert a user's edits to the Sandbox page.
在本例中，所有的参数通过GET请求传递只是为了便于理解。实际上， action=rollback 需要以POST方式请求，以GET方式请求将报错。
api.php?
回应
The Response section below is for the final POST request, to revert the edits to the Sandbox page.
{
"rollback": {
"title": "Sandbox",
"pageid": 94542,
"summary": "Reverted edits by [[Special:Contributions/41.190.3.231|41.190.3.231]] ([[User talk:41.190.3.231|talk]]) to last revision by [[User:Didicodes|Didicodes]]",
"revid": 381084,
"old_revid": 381083,
"last_revid": 381070
}
}
回应中的修订ID为：
revid- 回退创建的新修订版的ID。old_revid- 正在回退的最新修订版的ID。回退之前，这是当前版本。last_revid- 回退恢复的修订版本的ID。这是已回退的最新修订版本。

权限
Rollback requires both the edit and the rollback right on the target page; currently, this means that OAuth consumers, bot passwords etc. require both the editpage and the rollback grant – rollback alone is not enough!
