具有两个变量的 Powershell 循环

Question

我正在寻找一种方法将许多（100 个配对变量）项通过管道传输到此 powershell 脚本中。每个命令都有两个变量 ResourceGroup 和 AccountName。我可以构建一个数组，但不确定如何让脚本执行配对变量。

编辑：是否有任何方法可以从 CSV 导入这些变量，或者直接拉取它们。

$rgName = "<resource-group>"
$accountName = "<storage-account>"
$location = "<location>"

# Create a storage account with MinimumTlsVersion set to TLS 1.1.
New-AzStorageAccount -ResourceGroupName $rgName `
    -AccountName $accountName `
    -Location $location `
    -SkuName Standard_GRS `
    -MinimumTlsVersion TLS1_1

# Read the MinimumTlsVersion property.
(Get-AzStorageAccount -ResourceGroupName $rgName -Name $accountName).MinimumTlsVersion

# Update the MinimumTlsVersion version for the storage account to TLS 1.2.
Set-AzStorageAccount -ResourceGroupName $rgName `
    -AccountName $accountName `
    -MinimumTlsVersion TLS1_2

# Read the MinimumTlsVersion property.
(Get-AzStorageAccount -ResourceGroupName $rgName -Name $accountName).MinimumTlsVersion

如果你想将变量组合在一起，你可以使用 System.Management.Automation.PSCustomObject 的数组，然后迭代这个数组和运行你的代码：

param (
    [Parameter(Mandatory = $true)]
    [PSCustomObject[]]
    $StorageAccountData
)

foreach ($obj in $StorageAccountData) {
    $rgName = $obj.ResourceGroupName
    $accountName = $obj.AccountName
    $location = $obj.Location

    # Create a storage account with MinimumTlsVersion set to TLS 1.1.
    New-AzStorageAccount -ResourceGroupName $rgName `
        -AccountName $accountName `
        -Location $location `
        -SkuName Standard_GRS `
        -MinimumTlsVersion TLS1_1

    # Read the MinimumTlsVersion property.
    (Get-AzStorageAccount `
        -ResourceGroupName $rgName `
        -Name $accountName).MinimumTlsVersion

    # Update the MinimumTlsVersion version for the storage account to TLS 1.2.
    Set-AzStorageAccount `
        -ResourceGroupName $rgName `
        -AccountName $accountName `
        -MinimumTlsVersion TLS1_2

    # Read the MinimumTlsVersion property.
    (Get-AzStorageAccount `
        -ResourceGroupName $rgName `
        -Name $accountName).MinimumTlsVersion
}

然后你可以运行这个脚本像这样：

PS C:\Users\user> $storageAccountData = @(
>>     [PSCustomObject]@{
>>         ResourceGroupName = 'storageRG'
>>         AccountName = 'storage1'
>>         Location = 'australiaeast'
>>     }
>>     [PSCustomObject]@{
>>         ResourceGroupName = 'storageRG'
>>         AccountName = 'storage2'
>>         Location = 'australiaeast'
>>     }
>> )
PS C:\Users\user> script.ps1 -StorageAccountData $storageAccountData

如果你想管道这个到脚本中，你可以创建一个函数并使用ValueFromPipeline:

function MyFunction {
    [CmdletBinding()]
    param (
        [Parameter(
            Mandatory = $true, 
            ValueFromPipeline = $true
        )]
        [PSCustomObject[]]
        $StorageAccountData
    )
    # rest of your code
}

然后将 PSCustomObject 的数组向下传递，然后使用 $storageAccountData | MyFunction 管道传递给此函数。在调用函数之前，确保 dot source 脚本将函数加载到您的首选范围内。

如果您想从 CSV 文件中读取（例如存储-accounts.csv）：

AccountName,ResourceGroupName,Location
storage1,storageRG,australiaeast
storage2,storageRG,australiaeast

你只需要使用 Import-Csv:

$storageAccountData = Import-Csv -Path .\storage-accounts.csv

foreach ($obj in $storageAccountData) {
    # rest of your code
}
