解析Netsh输出

Question

我需要在powershell中解析netsh命令提供的输出。下面是我使用的命令

Netsh advfirewall show private

它证明了下面的输出

Private Profile Settings: 
----------------------------------------------------------------------
State                                 ON
Firewall Policy                       BlockInbound,AllowOutbound
LocalFirewallRules                    N/A (GPO-store only)
LocalConSecRules                      N/A (GPO-store only)
InboundUserNotification               Enable
RemoteManagement                      Disable
UnicastResponseToMulticast            Enable

Logging:
LogAllowedConnections                 Disable
LogDroppedConnections                 Disable
FileName                              %systemroot%\system32\LogFiles\Firewall\pfirewall.log
MaxFileSize                           4096

我的要求是访问上述输出中的每个值。有点像$result.state / $result.InboundUserNotification

我对PowerShell非常陌生，我在谷歌上搜索过这件事，却什么也找不到。

Answer 1

如果必须解析此输出，则可以执行以下操作：

$netsh = (Netsh advfirewall show private |
    Select-String -Pattern "\s{2,}") -replace '\s{2,}','=' -replace '\\','\\' -join [System.Environment]::NewLine
$result = [pscustomobject](ConvertFrom-StringData $netsh)

ConvertFrom-StringData方法的问题是哈希表输出没有排序。如果顺序很重要，您只需将每行拆分为属性/值对，就可以创建哈希表：

$hash = [ordered]@{}
Netsh advfirewall show private | Select-String -Pattern "\s{2,}" |
    Foreach-Object {
         $key,$value = $_ -split '\s{2,}'
         $hash[$key] = $value
    }
$result = [pscustomobject]$hash

下面是AdminOfThings答案使用ConvertFrom-StringData以及Foreach-Object的-Begin和-End参数的类似方法。

Netsh advfirewall show private |
     ForEach-Object -Begin{$ht = [ordered]@{}} {
        if($_ -match '\s{10,}')
        {
            $ht += $_ -replace '\\','\\' -replace '\s{10,}','=' | ConvertFrom-StringData
        }
    } -End{[PSCustomObject]$ht} -OutVariable result

和轻微的变化

Netsh advfirewall show private | Where-Object {$_ -match '\s{10,}'} |
     ForEach-Object -Begin{$ht = [ordered]@{}} {
        $ht += $_ -replace '\\','\\' -replace '\s{10,}','=' | ConvertFrom-StringData
    } -End{[PSCustomObject]$ht} -OutVariable result
