Question

有人可以提供以下代码无效的原因吗？之前我有这个工作，并且无法理解为什么New-PSSession无法验证ComputerName参数。完全错误下面的代码。

$Cred = Get-Credential DOMAIN\User

    # $TargetSession = Get-Content C:\Users\user\Downloads\tablets.txt

    $computers = gc 'C:\Users\user\Downloads\tablets.txt'

    foreach ($computer in $computers) {

            #Creates a new remote PowerShell Session and script block - enter the code you want to execute remotely from this block 
            $Session = New-PSSession $computer -Credential $cred {

                Invoke-Command -Session $Session -ScriptBlock {

                Start-Process “C:\windows\system32\notepad.exe”


            } 

            Remove-PSSession -Session $Session
        }
    }

退货输出：

New-PSSession : Cannot validate argument on parameter 'ComputerName'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

    + CategoryInfo          : InvalidData: (:) [New-PSSession], ParameterBindingValidationException

先谢谢

我已经修复了问题 - 它是脚本块中{}的不必要的嵌套。以下代码有效：

$cred = Get-Credential DOMAIN\Admin

    # $TargetSession = Get-Content C:\Users\user\Downloads\tablets.txt

    $computers = Get-Content C:\Users\rh.admin\Downloads\tablets.txt | Where-Object { $_ } 




    foreach ($computer in $computers)

        {
            #Creates a new remote PowerShell Session and script block - enter the code you want to execute remotely from this block 
            $Session = New-PSSession $computer -Credential $cred

                Invoke-Command -Session $Session -ScriptBlock {

                Start-Process “C:\windows\system32\notepad.exe”


            } 

            Remove-PSSession -Session $Session # 
        }

使用PowerShell在Scriptblock中调用Command到远程会话计算机
