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

问题描述

我目前正在 Azure 上构建应用服务，并想编写一个 PowerShell 脚本来从本地上传/删除文件到应用服务。我曾经Invoke-WebRequest上传文件和Invoke-RestMethod删除文件，但Catch [Exception]收到一条 405 消息。我需要对 Azure 连接执行身份验证吗？我怎样才能快速实施它？

### 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
   }

}
