Question

我试图在CSOM的帮助下找出在sharepoint中对任务列表所做的更改。（Microsoft.SharePoint.Client.dll）我能够通过List类的GetChanges方法查询更改，但不知道该怎么做。我特别想知道如何获取与特定列中的列表更改相关的信息，旧值，新值，进行更改的用户等。这是否可能？我知道Change.ChangeToken属性，但我不知道如何在PowerShell中实现它。这是我不完整的代码：

[Reflection.Assembly]::LoadFrom("$scriptdir\Microsoft.SharePoint.Client.dll")
$context = New-Object Microsoft.SharePoint.Client.ClientContext($siteURL)
$context.RequestTimeOut = 1000 * 60 * 10;
$context.AuthenticationMode = [Microsoft.SharePoint.Client.ClientAuthenticationMode]::Default
$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $securePassword)
$context.Credentials = $credentials
$web = $context.Web  
$site = $context.Site
$context.Load($web)  
$context.Load($site) 
$context.ExecuteQuery()
Set-Variable -Name "clientContext" -Value $context -Scope Global
Set-Variable -Name "rootSiteUrl" -Value $siteURL -Scope Global
Function Get-ListChanges {   
    $listName = "Tasks"
    $list = $clientContext.Web.Lists.GetByTitle($listName)
    $cq = new-object Microsoft.Sharepoint.Client.ChangeQuery($true,$true)
    $changes = $list.GetChanges($cq)
    $clientContext.Load($changes)
    $clientContext.ExecuteQuery()
    $changes.count
    foreach ($item in $changes) {   
        # get data here from specific column name/old values/newvalues
    }   
}

感谢您参与此活动！

更新：根据要求，$ item.GetType（）的结果为单个更改项目...

坦克，可以获得更改类型和更改时间：

$item | Select ChangeType,Time

我可能会在黑暗中捅，但您可能想要研究ChangeLogItemQuery类。它可能能够为您提供有关实际更改本身的更多信息（旧/新等）。如果我错了，请纠正我。
