SharePoint Online：查找使用 PowerShell 创建列表或库的人员

要求：查找谁在 SharePoint Online 中创建了列表或库。

了解谁在 SharePoint Online 中创建了库：

如果您想找出谁创建了 SharePoint Online 列表或库： 抱歉，无法通过 SharePoint Web 用户界面！您无法在任何地方获取“创建者”值。快速找到 SharePoint Online 列表或库的创建者的能力可能是故障排除或审核信息的关键部分。所以，PowerShell可以帮助快速找到这些信息！

SharePoint Online：查找使用 PowerShell 创建列表的人员

我们还没有在 CSOM 中公开 List.Author 属性。但是，我们可以从列表的 SchemaXML 中提取作者信息。

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

#Function to call a non-generic method Load
Function Invoke-LoadMethod() 
{
   param([Microsoft.SharePoint.Client.ClientObject]$Object,[string]$PropertyName)
   $ctx = $Object.Context
   $load = [Microsoft.SharePoint.Client.ClientContext].GetMethod("Load")
   $type = $Object.GetType()
   $clientLoad = $load.MakeGenericMethod($type)
   $Parameter = [System.Linq.Expressions.Expression]::Parameter(($type), $type.Name)
   $Expression = [System.Linq.Expressions.Expression]::Lambda([System.Linq.Expressions.Expression]::Convert([System.Linq.Expressions.Expression]::PropertyOrField($Parameter,$PropertyName),[System.Object] ), $($Parameter))
   $ExpressionArray = [System.Array]::CreateInstance($Expression.GetType(), 1)
   $ExpressionArray.SetValue($Expression, 0)
   $clientLoad.Invoke($ctx,@($Object,$ExpressionArray))
}

#Function to get user who created a SharePoint Online List or library
Function Get-SPOListAuthor($SiteURL,$ListName)
{
    Try
    {
        #Get Credentials to connect
        $Cred= Get-Credential

        #Setup the context
        $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
        $Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)

        #Get the List
        $List=$Ctx.Web.Lists.GetByTitle($ListName)
        $Ctx.Load($List)
        $Ctx.ExecuteQuery()

        #Get List Schema XML
        Invoke-LoadMethod -Object $List -PropertyName "SchemaXML"
        $Ctx.ExecuteQuery()

        #Extract Author from List Schema XML
        $ListSchema =  [xml] $List.SchemaXml
        $AuthorID = $ListSchema.List.Author
        $Author = $Ctx.web.GetUserById($AuthorID)
        $Ctx.Load($Author)
        $Ctx.ExecuteQuery()
        Return $Author
    }
    Catch {
        write-host -f Red "Error:" $_.Exception.Message
    }
}

#Set Parameters
$SiteURL="https://Crescent.sharepoint.com"
$ListName="Documents"

Get-SPOListAuthor -SiteURL $SiteURL -ListName $ListName

更新：最新版本的 CSOM 通过其 API 公开 List.Author 属性。因此，现在可以直接检索 SharePoint Online 列表的作者属性。例如。

#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
 
#Config Parameters
$SiteURL= "https://Crescent.sharepoint.com/sites/Marketing"
$ListName="Projects"
 
#Setup Credentials to connect
$Cred = Get-Credential
 
Try {
    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName,$Cred.Password)
   
    #Get the List Author
    $Web=$Ctx.Web
    $List= $Web.Lists.GetByTitle($ListName)
    $Ctx.Load($List)
    $Ctx.Load($List.Author)
    $Ctx.ExecuteQuery()
      
    Write-host -f Green $List.Author.Email
}
Catch {
    write-host -f Red "Error: " $_.Exception.Message
}
