如何使用 PowerShell 上传和删除 Azure Web 应用程序的文件

Question

我目前正在 Azure 上构建应用服务，并希望将 PowerShell 脚本写入 upload/delete 文件，从本地端传输到应用服务。我使用 Invoke-WebRequest 上传文件并使用 Invoke-RestMethod 删除文件，但是 Catch [Exception] 收到了一条 405 消息。我是否需要对 Azure 连接进行身份验证？如何快速实施？

### init
$strHTTPS="https://xxx.azurewebsites.net/test/"   
$LocalFolder = "D:\AzureSolution\local_backup\"
$TargetFolder = $strHTTPS +  "azure_backup/" 

#Connect to Azure app servuce
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$WebConnect = Invoke-WebRequest -URI $strHTTPS 
$WebContent = $WebConnect.Links | Select href

Foreach ($Item in $WebContent ) {
   $FileName = split-Path $Item.href -Leaf  

   #download file in local folder ---------------------------------> test OK
   $SourcefileName = $strHTTPS + $FileName
   $LocalFileName = $LocalFolder+$FileName
   Try{
      Invoke-WebRequest -Uri $SourcefileName -OutFile $LocalFileName -PassThru 
   }
   Catch [Exception] {
      $ExceptionMsgPut = $_.Exception.GetType().FullName, $_.Exception.Message
   }

   #Backup file in Azure app servuce -------------------------------> test Failed
   $TargetFileName = $TargetFolder + $FileName
   $UploadWeb = New-Object System.Net.WebClient
   Try{
      $UploadWeb.UploadFile($TargetFileName,"PUT",$LocalFileName)
   }
   Catch [Exception] {
      $ExceptionMsgUpload = $_.Exception.GetType().FullName, $_.Exception.Message
   }         

   #Delete Azure Soruce File when completed ------------------------> test Failed
   Try{
      Invoke-RestMethod -Uri $SourcefileName -Method Delete 
   }
   Catch [Exception] {
      $ExceptionMsgDelete = $_.Exception.GetType().FullName, $_.Exception.Message
   }

   #Delete Local file when completed -------------------------------> test OK
   Try{
      Remove-Item $LocalFileName -recurse
   }
   Catch [Exception] {
      $ExceptionMsgDeleteLocalfile = $_.Exception.GetType().FullName, $_.Exception.Message
   }

}

Answer 1

您可以使用KUDU VFS API

PUT /api/zip/{path} (Upload a zip file which gets expanded into the specified folder)

DELETE /api/vfs/{path} (Delete the file at path)
