azure - 如何使用 powershell 函数应用程序检索存储帐户 key ？

Question

我正在使用 powershell 函数应用来检索存储帐户 key ，但我无法访问资源。请帮助我。

$resourceGroup = "DemoResourceGroup"

$AccountName = "Demo"

$Key = (Get-AzStorageAccountKey -ResourceGroupName $resourceGroup -Name $AccountName)

Write-Host "storage account key 1 = " $Key

我收到以下错误:

2020-05-14T14:00:05Z [错误] 错误:Get-AzStorageAccountKey:“this.Client.SubscriptionId”不能为 null。 在 D:\home\site\wwwroot\TimerTrigger1\run.ps1:25 字符:8 + $key = Get-AzStorageAccountKey -ResourceGroupName "DocumentParser_FBI ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~ + CategoryInfo : CloseError: (:) [Get-AzStorageAccountKey]，ValidationException + FullQualifiedErrorId:Microsoft.Azure.Commands.Management.Storage.GetAzureStorageAccountKeyCommand

Answer 1

根据您提供的脚本，您使用Az模块。因此，如果您想选择使用哪个Azure订阅，则需要使用命令Select-AzSubscription 。另外，您还可以添加-Subscription "<subscription Id>"在Connect-AzAccoun以确保您在登录时选择正确的订阅。

例如

1. 创建服务主体

Import-Module Az.Resources # Imports the PSADPasswordCredential object
$credentials = New-Object Microsoft.Azure.Commands.ActiveDirectory.PSADPasswordCredential -Property @{ StartDate=Get-Date; EndDate=Get-Date -Year 2024; Password=<Choose a strong password>}
$sp = New-AzAdServicePrincipal -DisplayName ServicePrincipalName -PasswordCredential $credentials

将角色分配给服务主体。例如，在订阅级别将贡献者角色分配给 sp

New-AzRoleAssignment -ApplicationId <service principal application ID> -RoleDefinitionName "Contributor" `
-Scope "/subscriptions/<subscription id>"

脚本

$appId = "your sp app id"
$password = "your sp password"
$secpasswd = ConvertTo-SecureString $password -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ($appId, $secpasswd)

Connect-AzAccount -ServicePrincipal -Credential $mycreds -Tenant <you sp tenant id>
Get-AzSubscription -SubscriptionName "CSP Azure" | Select-AzSubscription

$resourceGroup = "nora4test"

$AccountName = "qsstorageacc"

$Key = (Get-AzStorageAccountKey -ResourceGroupName $resourceGroup -Name $AccountName)[0].Value

Write-Host "storage account key 1 = " $Key
