Question

不太清楚为什么以下不起作用。基本上，有多个基于键值的elseif语句。

我测试的服务器的设置$valuePassword等于我输入的随机字符，我还将$valueAutoLogin设置为'1'。但是，我得到的结果是低于哪个没有显示任何东西？

另外 - 你能想到一个更好的方法来做这个而不是多个elseif的声明吗？

clear
Import-Module PSRemoteRegistry
$computers = Get-Content -Path C:\MANNY\Servers.txt

foreach($computer in $computers)
{
Write-Host "Checking $computer"

#Check if key exists
$valuePassword = Get-RegValue -ComputerName $Computer -Key 'SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon' -Value DefaultPassword
$valueAutoLogin = Get-RegValue -ComputerName $Computer -Key 'SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon' -Value AutoAdminLogon


if($valuePassword -eq $null -and $valueAutoLogin -eq $null)
{Write-Host "$computer not set"}

elseif($valuePassword -notcontains $null -and $valueAutoLogin -eq $null)
{Write-Host "$computer has Password set"}

elseif($valuePassword -eq $null -and $valueAutoLogin -eq '1')
{Write-Host "$computer has Autologin set but not password"}

elseif($valuePassword -notcontains $null -and $valueAutoLogin -eq '1')
{Write-Host "$computer has Autologin set and password set - AUTOLOGIN IS POSSIBLY SET"}

}

尝试使用内置方法时会得到什么结果？此外，您应添加else分支以报告意外值。

Get-Content "C:\MANNY\Servers.txt" | % {
  $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey("LocalMachine", $_)
  $key = $reg.OpenSubKey("SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon")

  $valuePassword  = $key.GetValue("DefaultPassword")
  $valueAutoLogin = $key.GetValue("AutoAdminLogon")

  $key.Close()
  $reg.Close()

  if ($valuePassword -eq $null -and $valueAutoLogin -eq $null) {
    Write-Host "$_ not set"
  } elseif ($valuePassword -ne $null -and $valueAutoLogin -eq $null) {
    Write-Host "$_ has Password set"
  } elseif ($valuePassword -eq $null -and $valueAutoLogin -eq '1') {
    Write-Host "$_ has Autologin set but not password"
  } elseif ($valuePassword -ne $null -and $valueAutoLogin -eq '1') {
    Write-Host "$_ has Autologin set and password set - AUTOLOGIN IS POSSIBLY SET"
  } else {
    Write-Host "$_: unexpected AutoLogin value: $valueAutoLogin"
  }
}
