P/Invoke SHSetKnownFolderPath 失败

Question

我认为这将是一个足够简单的脚本。我在这里看到这篇关于如何使用 powershell 将文件夹重定向到 OneDrive 的文章：https://stealthpuppy.com/onedrive-intune-folder-redirection/

我意识到这个脚本对我不起作用，因为它的编写方式需要用户上下文并且不能运行使用 Task Scheduler 静默地使用，所以我开始尝试“重写”脚本使用系统上下文。除了我似乎无法理解的一大块之外，一切似乎都在工作。我认为它是 C#，我只熟悉 powershell。我只关心重定向下载文件夹，所以他就是我的。

除了我在第 74 行收到一条错误消息外，一切似乎都正常， “重定向 {374DE290-123F-4565-9164-39C4925E467B} 时出错。Return 代码 -2147024894 = 系统找不到指定的文件

我几乎花了一整天的时间来解决这个问题，但一无所获。如有任何帮助，我们将不胜感激！

你有两个问题：

眼前的技术问题：The system cannot find the file specified 表示无法识别指定的 KNOWNFOLDERID GUID。
- 就是说，在您的两个 GUID 中，它是 {7d83ee9b-2244-4e70-b1f5-5393042af1e4}，而不是您的错误消息中提到的 {374DE290-123F-4565-9164-39C4925E467B}（下载文件夹），这是未知的。
概念性问题：您正在尝试为 特定用户 调用 SHSetKnownFolderPath，这需要您传递所谓的访问令牌将感兴趣的用户表示为 hToken 参数。
- 由于您将 0 传递给 hToken，因此您总是在为当前用户更新。

如果您想避免通过 LogonUser WinAPI function, you can bypass SHSetKnownFolderPath calls and write directly to the registry, as your code in part already does; however, note that while that should work as of this writing, doing so is discouraged 获取代表其他用户的访问令牌的额外复杂性，并且可能在将来的某个时候停止工作。
