将 Azure 存储帐户属性保存到 CSV

Question

我正在运行按照一段代码从我所有订阅的所有存储帐户中获取存储帐户 TLS 版本。目前唯一的问题是我无法将结果导出为 CSV，因此我无法转发结果。向代码中添加什么以便将存储帐户名称、资源组、订阅和 TSL 版本保存到一行但在不同的列中？

  [PsObject[]]$data = @()

#$Subscriptions = Get-AzSubscription
#foreach ($sub in $Subscriptions) {
    #Get-AzSubscription -SubscriptionName $sub.Name | Set-AzContext
    $storageaccounts = Get-AzStorageAccount
    $storageaccounts| ForEach-Object {
      Write-Host Checking $_.StorageAccountName
      $tls = (Get-AzStorageAccount -ResourceGroupName $_.ResourceGroupName -Name $_.StorageAccountName).MinimumTlsVersion
      # create a custom object to store the information about a storage account 
      $tlsVersionData = [PsObject]@{
        "StorageAccountName" = $_.StorageAccountName
        "ResourceGroupName" = $_.ResourceGroupName
        "TLSVersion" = $tls
      }
      # add that custom object to the array
      $data += $tlsVersionData
    }
#}

# write a CSV file containing this data
$data | Export-Csv C:\temp\data.csv

写入主机在屏幕上显示有关存储帐户的正确信息，但我有点不知道如何将数据保存到 CSV。

请尝试如下操作：

[PsObject[]]$data = @() #define an array that will hold the data

$Subscriptions = Get-AzSubscription
foreach ($sub in $Subscriptions) {
    Get-AzSubscription -SubscriptionName $sub.Name | Set-AzContext
    $storageaccounts = Get-AzStorageAccount
    $storageaccounts| ForEach-Object {
      Write-Host Checking $_.StorageAccountName
      $tls = (Get-AzStorageAccount -ResourceGroupName $_.ResourceGroupName -Name $_.StorageAccountName).MinimumTlsVersion
      # create a custom object to store the information about a storage account 
      $tlsVersionData = [PsObject]@{
        "StorageAccountName" = $_.StorageAccountName
        "ResourceGroupName" = $_.ResourceGroupName
        "TLSVersion" = $tls
      }
      # add that custom object to the array
      $data += $tlsVersionData
    }
}

# write a CSV file containing this data
$data | Export-Csv .\data.csv

尽量避免使用 += 加法向数组（具有静态长度）添加元素。
这样做会浪费时间和内存，因为对于添加到其中的每一项，整个数组都需要在内存中重建。

修复方法是让 PowerShell 为您收集数据，如下所示。

关于 Csv 的输出，将开关 -NoTypeInformation 添加到 Export-Csv cmdlet，这样它就不会在顶部写入字段类型信息。

$Subscriptions = Get-AzSubscription
$data = foreach ($sub in $Subscriptions) {
    # suppress output on this line
    $null = Get-AzSubscription -SubscriptionName $sub.Name | Set-AzContext
    Get-AzStorageAccount | ForEach-Object {
        Write-Host Checking $_.StorageAccountName
        $tls = (Get-AzStorageAccount -ResourceGroupName $_.ResourceGroupName -Name $_.StorageAccountName).MinimumTlsVersion
        # create and output a custom object to store the information about a storage account 
        [PsCustomObject]@{
            StorageAccountName = $_.StorageAccountName
            ResourceGroupName  = $_.ResourceGroupName
            TLSVersion         = $tls
        }
    }
}

# write a CSV file containing this data
$data | Export-Csv -Path .\data.csv -NoTypeInformation

注意：Export-Csv默认使用逗号作为字段分隔符。如果您想要不同的字符，可以使用 -Delimiter 参数指定。

事实上，您可以像这样在没有 ForEach-Object 循环的情况下编写上面的代码：

$Subscriptions = Get-AzSubscription
$data = foreach ($sub in $Subscriptions) {
    # suppress output on this line
    $null = Get-AzSubscription -SubscriptionName $sub.Name | Set-AzContext
    # let Select-Object output the objects that will be collected in variable $data
    Get-AzStorageAccount | Select-Object StorageAccountName, ResourceGroupName,
                                         @{Name = 'TLSVersion'; Expression = {$_.MinimumTlsVersion}}

}

# write a CSV file containing this data
$data | Export-Csv -Path .\data.csv -NoTypeInformation
