如何使用 PowerShell 从 SharePoint 获取所有文档的列表？

Question

我想使用 PowerShell 从 SharePoint 检索所有文档，但目前我只能检索特定站点的文档。

这是我正在使用的代码：

#Load SharePoint CSOM Assemblies
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"

#Set Parameters
$SiteURL="https://xxx.sharepoint.com/sites/CRMDevelopment"
$LibraryName="Documents"
$ReportOutput = "C:\users\xxx\downloads\VersionHistory.csv"

Try {
    #Setup Credentials to connect
    $Cred= Get-Credential
    $Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)

    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $Ctx.Credentials = $Credentials

    #Get the web & Library
    $Web=$Ctx.Web
    $Ctx.Load($Web)
    $List = $Web.Lists.GetByTitle($LibraryName)
    $Ctx.ExecuteQuery()

    #Get All Files of from the document library - Excluding Folders
    $Query =  New-Object Microsoft.SharePoint.Client.CamlQuery
    $Query.ViewXml = "<View Scope='RecursiveAll'><Query><Where><Eq><FieldRef Name='FSObjType' /><Value Type='Integer'>0</Value></Eq></Where><OrderBy><FieldRef Name='ID' /></OrderBy></Query></View>"
    $ListItems=$List.GetItems($Query)
    $Ctx.Load($ListItems)
    $Ctx.ExecuteQuery()

    $VersionHistoryData = @()
    #Iterate throgh each version of file
    Foreach ($Item in $ListItems)
    {
        ##more code goes here.
    }
}

Demo to iterate all site collections by PnP PowerShell and SharePoint online management shell, if you want to access the library in all site collections, the account need access to all site collections(admin not has permissions to all site collections by default).

#region Variables 
$AdminName = "admin@xxx.onmicrosoft.com" 
$Password = "password"
#endregion Variables

#region Credentials 
[SecureString]$SecurePass = ConvertTo-SecureString $Password -AsPlainText -Force 
$credentials = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $AdminName, $(convertto-securestring $Password -asplaintext -force)
#endregion Credentials
#Config Parameters
$AdminSiteURL="https://xxx-admin.sharepoint.com"
#$ReportOutput = "C:\users\xxx\downloads\VersionHistory.csv"

#Connect to SharePoint Online Admin Center
Connect-SPOService -Url $AdminSiteURL –Credential $credentials

#Get All site collections
$SiteCollections = Get-SPOSite -Limit All
Write-Host "Total Number of Site collections Found:"$SiteCollections.count -f Yellow

#Loop through each site collection and retrieve details
Foreach ($Site in $SiteCollections)
{
    #Test for specific site
#if($Site.URL -eq "https://xxx.sharepoint.com/sites/lee"){
    Write-Host "Processing Site Collection :"$Site.URL -f Yellow

    Connect-PnPOnline -Url $Site.URL -credentials $credentials
    $items=Get-PnPListItem -List Documents -Query "<View Scope='RecursiveAll'><Query><Where><Eq><FieldRef Name='FSObjType' /><Value Type='Integer'>0</Value></Eq></Where><OrderBy><FieldRef Name='ID' /></OrderBy></Query></View>"
    Foreach ($Item in $items)
    {
        Write-Host $Item.FieldValues["FileRef"]
    }
#}
}
Write-Host "--"
