如何在 PowerShell 中使用 CSOM 设置Web.SiteLogoUrl property：

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client")
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.Runtime")

Function Get-SPOCredentials([string]$UserName,[string]$Password)
{
   $SecurePassword = $Password | ConvertTo-SecureString -AsPlainText -Force
   return New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($UserName, $SecurePassword)
}

Function Web-SetLogo([Microsoft.SharePoint.Client.ClientContext]$Content,[string]$SiteLogoUrl)
{
   $Context.Web.SiteLogoUrl = $SiteLogoUrl
   $Context.Web.Update()
   $Context.ExecuteQuery()
}

$UserName = "username@contoso.onmicrosoft.com"
$Password = Read-Host -Prompt "Enter the password"    
$Url = "https://contoso.sharepoint.com/"

$context = New-Object Microsoft.SharePoint.Client.ClientContext($Url)
$context.Credentials = Get-SPOCredentials -UserName $UserName -Password $Password

Web-SetLogo -Content $context -SiteLogoUrl "/SiteAssets/ContosoLogo.jpg"

        $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 Root web
        $Web = $Ctx.Web
