从 Azure 自动化帐户运行时，Get-AzureBlobContent 引发错误

Question

我在尝试从我的 Azure 自动化帐户从 Azure 存储帐户下载 blob（JSON 文件）时收到错误消息。它看起来像一个授权问题。

这适用于我的本地笔记本电脑，但不适用于 Azure 自动化帐户。即使我将容器“公开”也不起作用

我已为资源组（自动化帐户 + 存储帐户留在此 RG 中）上的自动化帐户服务原则分配 OWNER 权限，特别是在存储帐户上：

下面是代码：

$connectionName = "AzureRunAsConnection"
try
{
    # Get the connection "AzureRunAsConnection "
    $servicePrincipalConnection=Get-AutomationConnection -Name $connectionName         

    "Logging in to Azure..."
    Add-AzureRmAccount `
        -ServicePrincipal `
        -TenantId $servicePrincipalConnection.TenantId `
        -ApplicationId $servicePrincipalConnection.ApplicationId `
        -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint 
}
catch {
    if (!$servicePrincipalConnection)
    {
        $ErrorMessage = "Connection $connectionName not found."
        throw $ErrorMessage
    } else{
        Write-Error -Message $_.Exception
        throw $_.Exception
    }
}

$config_file_resource_group_name = "vg-datalake-manjunath"
$config_file_storage_account_name = "datalakelog"
$primary_key = (Get-AzureRmStorageAccountKey -ResourceGroupName $config_file_resource_group_name -AccountName $config_file_storage_account_name).value[0]
 $config_file_context = New-AzureStorageContext -StorageAccountName $config_file_storage_account_name -StorageAccountKey $primary_key

 Get-AzureStorageBlobContent -Blob "mw_services.json" -Container "fwconfigfiles" -Destination "C:\temp\mw_services.json" -Context $config_file_context

 get-content "C:\temp\mw_services.json" | write-output

错误：

Get-AzureStorageBlobContent : The remote server returned an error: (403) Forbidden. HTTP Status Code: 403 - HTTP Error

可能的原因是您可以配置到选定的网络进行访问。

如果您启用此选项，并且是否勾选“允许受信任的 Microsoft 服务访问”，您将收到此错误，因为自动化未列在 MS 受信任的服务下。见https://docs.microsoft.com/en-us/azure/storage/common/storage-network-security#trusted-microsoft-services。
