我正在尝试使用 powershell 从我们的团队站点（sharepoint？）下载单个文件。powershell 的原因是由于我们的策略（映射、在库中打开、webDav 访问...），任何其他方法都失败了

我已经尝试了几个我在这里找到的 PS 脚本，或者在网络上，但仍然没有任何效果......主要是我收到了诸如禁止或无效凭据之类的错误......

我正在使用的最新版本：

function GetSharePointListContext($userName, $password, $isOnline, $siteUrl, $listTitle)
{
    $securePassword = ConvertTo-SecureString $password -AsPlainText -Force
    $Context = New-Object Microsoft.SharePoint.Client.ClientContext($siteUrl) 
    if($isOnline -eq $true)
    {
        $Context.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($userName, $securePassword)  -Verbose:$false
    }
    else
    {
        if($userName -like "*@xyz.com")
        {
            $context.AuthenticationMode = [Microsoft.SharePoint.Client.ClientAuthenticationMode]::Default
            $context.Credentials = New-Object System.Net.NetworkCredential($userName, $securePassword) -Verbose:$false  
            $context.add_ExecutingWebRequest( ${function:ExecutingWebRequestEventHandler_NoFormsAuth} )
        }
        else
        {
            $Context.AuthenticationMode = [Microsoft.SharePoint.Client.ClientAuthenticationMode]::FormsAuthentication
            $Context.FormsAuthenticationLoginInfo = New-Object Microsoft.SharePoint.Client.FormsAuthenticationLoginInfo($userName, $securePassword) -Verbose:$false 
        }
    }

    $targetList = $Context.Web.Lists.GetByTitle($listTitle) #target list  

    $Context.Load($targetList)  
    $Context.ExecuteQuery()  

    return $targetList;
}    

Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Taxonomy.dll"
Add-Type -Path 'C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.dll' 
Add-Type -Path 'C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.Online.SharePoint.PowerShell.dll'


$userName= ""
$password = ""
$isOnline = $false
$siteUrl = "https://hub.xyzgroup.net/teams/xyzteam/"
$listTitle = "Process Analysts Workplace"

GetSharePointListContext $userName $password $isOnline $siteUrl $listTitle

这将导致：

使用“0”参数调用“ExecuteQuery”的异常：“远程服务器返回错误：(403) Forbidden。” 在 C:\Learning\PowerShell\test8.ps1:28 char:5 + $Context.ExecuteQuery() + ~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo ： NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : WebException

知道有什么问题吗？我意识到这个脚本不是下载文件，而是导致同样的错误：/

谢谢。
