我试过这个问题的一切，但无法找到错误。GET请求目前不允许更新。 ON CopyDocumentSet
我的网站的结构是这样的
会议（SiteCollection，RootWeb）
1.1 BoardOFDirectors（子网站）
1.1.1 20120101（子网站）
1.1.2 20120202 （子网站）
内部会议有一个名为会议的列表。在每个子网站内部有一个名为议程点的文件集列表。
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。我在想什么？
GET请求当前不允许更新。要允许更新GET，请在SPWeb上设置'AllowUnsafeUpdates'属性。
