Question

我使用Powershell将文件从本地驱动器上传到共享点站点

我有一个列表“ Documents”，他包含一个名为“ X”的文件夹

我的问题是：如何将文件上传到X文件夹

这是我的代码：

$SiteURL = "domain/sites/testing/"
$libraryName="Documents/X"
$SPOnlineUserName="user@domain"

当我上传到文档（$libraryName变量为“ Documents”）时，脚本运行良好

但是在$libraryName="Documents/X"文件夹中，出现此错误：

List 'Documents/X' does not exist at site with URL 'domain/sites/testing'

有解决此问题的想法吗？

[编辑]

我可以通过浏览器访问“ X”文件夹。

最好。

针对大文件上传进行更新：

Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"

$SiteURL="https://tenant.sharepoint.com/sites/dev"
$User = "user@tenant.onmicrosoft.com"  
$Password = '*********************' 
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($User,(ConvertTo-SecureString $Password -AsPlainText -Force))
$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$ctx.Credentials = $Credentials
