文件上传到 Sharepoint Online 上的错误文件夹

Question

我一直在尝试使用 PowerShell 将文件和文件夹上传到 SharePoint Online。我快到了，但是递归方法中的代码有问题。它会将文件上传到它应该上传的文件夹中。例如，如果我有一个文件夹结构并且每个文件夹有 3 个文件：

文件夹1\文件夹2\文件夹3

Folder2 和 Folder3 中的文件会上传到文件夹 3。

我知道文件夹会先上传，所以$UploadSubFolder 的路径会更新到较低的文件夹，但我不知道如何修复它！你能不能写一点代码让文件先上传？

谁能帮我解决这个问题？谢谢！

用法

$Url = "https://contoso.sharepoint.com"
$UserName = "username@contoso.onmicrosoft.com"
$Password = "password"
$TargetListTitle = "Documents"   #Target Library
$SourceFolderPath = "C:\Users\me\Upload"  #Source Physical Path 


#Upload files
Upload-Files -Url $Url -UserName $UserName -Password $Password -TargetListTitle $TargetListTitle -SourceFolderPath $SourceFolderPath

关键点：

• 保留文件夹结构
