使用 Get-WmiObject 将多个对象添加到数组中 | Where对象

Question

我有下面的工作代码，它被用作 SCCM 中的检测子句，以检测是否安装了服务器功能，作为服务器功能脚本安装程序的一部分。

$role = Get-WmiObject -Class Win32_ServerFeature | Where-Object {$_.ID -eq 2}
if ($role) {
    Write-Host "Installed"
}
else {
}

问题，问题是，上面只有 1 个服务器功能，我如何使用数组添加 class 中的每个相关服务器功能，以便检测子句 100% 准确？

本案例中的相关角色是：

Web-Server Web-ISAPI-Ext Web-Windows-Auth Web-Metabase Web-WMI RDC

在已经安装了它们的机器上，我可以提取这些信息来添加：

Get-WmiObject -Class win32_serverfeature | select Name, ID

Name                                ID

注意：这是为旧服务器设计的运行 2008 SP2 所以，这意味着我有旧的工具集可以使用（ServerFeaturecmd.exe - Install-WindowsFeature 和 Get-Windowfeature不能使用)

我的想法是这样的，但是，将对象放入数组而不是单个变量？这似乎不是最简单的方法。

$roleID2 = Get-WmiObject -Class Win32_ServerFeature | Where-Object {$_.ID -eq 2}
$roleID140 = Get-WmiObject -Class Win32_ServerFeature | Where-Object {$_.ID -eq 140}
$roleID141 = Get-WmiObject -Class Win32_ServerFeature | Where-Object {$_.ID -eq 141}
$roleID162 = Get-WmiObject -Class Win32_ServerFeature | Where-Object {$_.ID -eq 162}
$roleID164 = Get-WmiObject -Class Win32_ServerFeature | Where-Object {$_.ID -eq 164}
$roleID179 = Get-WmiObject -Class Win32_ServerFeature | Where-Object {$_.ID -eq 179}

If ($roleID2 -and $roleID140 -and $roleID141 -and $roleID162 -and $roleID164 $roleID179) {
    Write-Host "Installed"
}
else {
}

我怀疑我完全误解了你的问题，但无论如何这就是我的回答 ...

你为什么要反复调用来创建你已经拥有的东西？ [皱眉]您拥有来自该 WMI 调用的整个属性集的集合。如果您只想要其中的一个子集，请创建一个包含您想要的属性的 [PSCustomObject]。

不要重复调用同一个愚蠢的 WMI class！ [咧嘴一笑]

我的 win7ps5.1 机器上没有 class 作为 Win32_ServerFeature，所以下面的演示是与其他 classes 一起使用的。

[注 1] 您可以调用几个 classes，将它们保存到唯一的 $Vars，然后使用它们构建整个子集捆绑的属性。

[注 2] 您可以在远程系统上使用 Invoke-Command 到运行在脚本块中并行调用所有这些。

Answer 3

如果你只是想减少代码，你可以这样写：

$featureIDs = @(2, 140, 141, 162, 164, 179)
$compliant = $true

foreach($ID in $featureIDs) {
    $compliant = $compliant -and ((Get-WmiObject -Class Win32_ServerFeature | Where-Object {$_.ID -eq $ID}) -ne $null)
}

if ($compliant) {
    Write-Host "Installed"
}
else {
}

然而，这确实执行了大量 WMI 调用，而不仅仅是您需要的那个。我不确定使用某些 WQL 语法是否可以做得更好（因为 WQL 非常有限），但如果我找到更优雅的方法，我会更新它。我现在主要发布这个相当粗略的解决方案，因为我想我理解你想要实现的目标，希望能激发出更好的解决方案。
