Question

此脚本应检查服务是否在server1上启动，如果不是则启动它。

我收到错误声明：

方法调用失败，因为[Deserialized.System.ServiceProcess.ServiceController]不包含名为＆＃39; refresh＆＃39;
的方法

但是，在本地服务而不是远程PC上使用$cred = Import-Clixml -Path F:\Powershell\Safe\xxxx.txt $server1 = Invoke-Command -ComputerName xxxx -ArgumentList $servicename -ScriptBlock { Param($servicename) Get-Service -Name $servicename } -Credential $cred if ($server1.Status -eq "Running"){ Write-Host "The Telephony service is started on xxxx" } else { Write-Host "The Telephony service is stopped on xxxx, starting up service" Start-Sleep -Seconds 5 Invoke-Command -ComputerName xxxx -ArgumentList $servicename -ScriptBlock { Param($servicename) Start-Service -Name $servicename } -Credential $cred Write-Host "Telephony service is starting xxxx" Start-Sleep -Seconds 10 $server1.Refresh() if ($server1.status -eq "Running") { Write-Host "Telephony service is now started on xxxx" } else { Write-Host "The Telephony service failed to start on xxxx please check services and try again."命令时工作时，它可以正常工作。如何在远程PC上刷新变量以获取服务状态？

每次要使用脚本的第二行获取状态时，都必须查询服务。方法在序列化时被剥离，当从远程服务器返回对象时会发生这种情况。每次要获取该服务的当前状态时，您都需要运行：

$cred = Import-Clixml -path F:\Powershell\Safe\xxxxxxxx.txt 

$SBlock = {
    Param($servicename)

    $Service = Get-Service -name $servicename
    if ($Service.Status -eq "Running"){
        "The Telephony service is started on xxxxxxxxx"
    }
    Else{
        "The Telephony service is stopped on xxxxxxxxx, starting up service"
        start-sleep -seconds 5
        Start-Service -name $servicename
        "Telephony service is starting xxxxxxxxx"
        start-sleep -seconds 10
        $Service.Refresh()
        if ($server1.status -eq "Running"){
            "Telephony service is now started on xxxxxxxxx"
        }
        else {
            "The Telephony service failed to start on xxxxxxxxx please check services and try again."
        }
    }
}

Invoke-Command -ComputerName xxxxxxxxx -ArgumentList $servicename -ScriptBlock $SBlock -Credential $cred

或者将其全部放在一个脚本块中，并在远程服务器上完成所有操作。
