New-AzWebAppBackup：操作返回无效状态代码 'Bad Request'

Question

当我尝试使用 New-AzWebAppBackup cmdlet 在 Azure Powershell 上执行 Azure 应用服务备份时，如下所述：

https://docs.microsoft.com/en-us/powershell/module/az.websites/New-AzWebAppBackup?view=azps-3.3.0

我收到以下错误消息：

PS Azure:\> New-AzWebAppBackup -ResourceGroupName "MyResourceGroup" -Name "MyWebApp" -StorageAccountUrl "https://mystorageaccount.file.core.windows.net/"
New-AzWebAppBackup : Operation returned an invalid status code 'BadRequest'
At line:1 char:1

+ CategoryInfo          : CloseError: (:) [New-AzWebAppBackup], DefaultErrorResponseException
+ FullyQualifiedErrorId : Microsoft.Azure.Commands.WebApps.Cmdlets.WebApps.NewAzureWebAppBackup

有人知道我错过了什么吗？我感谢任何建议。非常感谢。

您好，欢迎来到 Stack Overflow！

希望您的 webapp 满足能够进行备份的先决条件。备份和还原功能要求应用服务计划处于 Standard 层或 Premium 层。有关完整详细信息，请参阅 Requirements and restrictions。

我最初在执行 cmdlet 时遇到了同样的错误。但是，通过 cmdlet 传递 -debug 开关帮助我更好地理解错误：

{
 "ErrorEntity": {
 "ExtendedCode": "04205",
 "MessageTemplate": "The provided URI is not a SAS URL for a container (it needs to be https and it has to have 2 segments).",
 "Parameters": [],
 "Code": "BadRequest",
 "Message": "The provided URI is not a SAS URL for a container (it needs to be https and it has to have 2 segments)."
}

-StorageAccountUrl 参数需要传递 SAS URL（请参阅 this 文档）。您的存储帐户的 SAS URL 格式为：

sasurl=https://$storagename.blob.core.windows.net/$container$sastoken

要生成 SAS 令牌，运行如下：

# Retrieve one of the Storage Account keys
$key = (Get-AzStorageAccountKey -ResourceGroupName "<rg-name>" -AccountName "<storage-account-name>").Value[0]

# Populate the Storage Account context
$ctx = New-AzureStorageContext -StorageAccountName "<storage-account-name>" -StorageAccountKey $key

# Generate the SAS token
$sastoken = New-AzureStorageContainerSASToken -Name "<container-name>" -Permission rwdl -Context $ctx

# Generate the SAS URL
$sasurl = "https://<storage-account-name>.blob.core.windows.net/<container-name>$sastoken"

# Create a backup
New-AzureRmWebAppBackup -ResourceGroupName "<rg-name>" -Name "<app-name>" -StorageAccountUrl $sas -BackupName "<backup-name>"

成功执行以上命令应该让您创建备份。响应看起来像这样：

希望对您有所帮助！
