Question

我有下面的工作代码，该代码用作SCCM中的检测子句，以检测是否已将服务器功能安装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 {
}

问题是，以上仅是服务器功能中的1个，我将如何使用数组在类中的每个相关服务器功能中进行添加，以使检测子句的准确度达到100％？

在这种情况下的相关角色是：

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，我可以提取此信息以添加到其中：

Get-WmiObject -Class win32_serverfeature | select Name, ID

Name                                ID

注意：这是为运行2008 SP2的旧服务器设计的，因此，这意味着我可以使用较旧的工具集（ServerFeaturecmd.exe-无法使用Install-WindowsFeature和Get-Windowfeature）

谢谢

Answer 1

如果只想减少代码，则可以这样编写：

$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 {
}

但是，这确实完成了许多WMI调用，而不只是您需要的WMI调用。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），但是如果我找到更优雅的方式，我将对此进行更新。我现在主要是发布这个相当粗糙的解决方案，因为我想我理解您想要实现的目标，以期寻求更好的解决方案。

Answer 2

我在想什么，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 {
}

Answer 3

我怀疑我完全误解了您的问题，但这还是我的答案 ...

您为什么要重复打电话来创建自己已有的东西？ [皱眉]，您可以从该WMI调用中收集整个属性集。如果只需要它们的子集，则创建一个包含所需属性的[PSCustomObject]。

请勿重复调用同一愚蠢的WMI类！ [咧嘴]

我的win7ps5.1框上没有Win32_ServerFeature这样的类，因此下面的演示与其他类一起使用。

[注1]，您可以调用几个类，将它们保存到唯一的$ Vars中，然后使用它们来构建整个属性束的子集。

[注2]，您可以使用Invoke-Command在脚本块中调用所有这些命令，以在远程系统上并行运行它们。
