GET请求目前不允许更新。在CopyDocumentSet上

我已尝试过这个问题,但无法找到错误。

我网站的结构就像这样

会议(SiteCollection,RootWeb)

1.1 BoardOFDirectors(子网站)

1.1.1 20120101(子网站)

1.1.2 20120202(子网站)

在会议内部有一个名为会议的清单。在每个子网站内都有一个名为带有文档集的议程点列表。

我创建了一个自定义操作,将议程点从一个会议站点复制到下一个会议站点。

我在CopyTo方法中遇到以下异常。正如你所看到的那样,我在任何地方都设置了allowunsafeupdates = true。我错过了什么?

GET请求目前不允许更新。要允许GET上的更新,请在SPWeb上设置“AllowUnsafeUpdates”属性。
