我试图捕获ARM模板输出，并将其传递到下一个运行的脚本中。为此，我正在执行以下步骤，所有这些都是用Azure DevOps完成的。

在ARM模板中声明输出。

 "outputs": {
    "adminUsername": {
        "type": "string",
        "value": "[parameters('adminUsername')]"
    },
     "virtualMachineName": {
         "value": "[parameters('virtualMachineName')]",
         "type": "string"
        }
}

将ARM模板输出传递到第一个Azure脚本中，将每个输出值声明为管道变量。因此，这可以用于我的下一个任务.

    function Convert-ArmOutputToPsObject {
      param (
        [Parameter(Mandatory=$true)]
        [string]
        $ArmOutputString
      )
      if ($PSBoundParameters['Verbose']) {
        Write-Host "Arm output json is:"
        Write-Host $ArmOutputString
      }
      $armOutputObj = $ArmOutputString | ConvertFrom-Json
      $armOutputObj.PSObject.Properties | ForEach-Object {
          $type = ($_.value.type).ToLower()
          $keyname = "ArmOutputs.$($_.name)"
          $value = $_.value.value

          if ($type -eq "securestring") {
              Write-Host "##vso[task.setvariable variable=$keyname;issecret=true]$value"
              Write-Host "Added Azure DevOps secret variable '$keyname' ('$type')"
          } elseif ($type -eq "string") {
              Write-Host "##vso[task.setvariable variable=$keyname]$value"
              Write-Host "Set environment variable to ($env:$keyname)"
              Get-ChildItem Env:
              Write-Host "ARMoutput Id ($keyname)
          } else {
              Throw "Type '$type' is not supported for '$keyname'"
          }
      }
    }
    Convert-ArmOutputToPsObject -ArmOutputString '$(ArmOutputs)' -Verbose

上面脚本的输出是成功的:从这里我可以看到管道变量被设置和可用。

Arm output json is:
{"adminUsername":{"type":"String","value":"azureuser"},"virtualMachineName":{"type":"String","value":"vm-test"}}
**##[debug]Processed: ##vso[task.setvariable variable=adminUsername;isOutput=true]azureuser**
Added Azure DevOps variable 'adminUsername' ('string') with value 'azureuser'
##[debug]Processed: ##vso[task.setvariable variable=virtualMachineName;isOutput=true]vm-test
Added Azure DevOps variable 'virtualMachineName' ('string') with value 'vm-test'

我试图在我的第二个Azure powershell脚本中使用上面创建的管道变量"virtualMachineName“作为参数。

function Disk-encryption {
                                param (
                                [Parameter(Mandatory=$true)]
                                [string]
                                $virtualMachineName)
write-host $virtualMachineName
}
Disk-encryption -virtualMachineName '$(virtualMachineName)'

此脚本的执行将抛出以下错误

错误：

Line |
   2 | Disk-encryption -virtualMachineName $(virtualMachineName)
     |                                   ~~~~~~~~~~~~~~~~~~
     | The term 'virtualMachineName' is not recognized as the name of
     | a cmdlet, function, script file, or operable program. Check
     | the spelling of the name, or if a path was included, verify
     | that the path is correct and try again.

甚至只是尝试只打印‘写-主机$virtualMachineName’，但得到了同样的错误。$virutalMachineName似乎不能作为管道变量使用。

有人能帮忙吗？我的问题是:1.从成功执行的任务中，在管道中有哪些管道变量被设置和全局可用?如果是，如何在我的第二个Azure Powershell脚本中使用新创建的管道变量？
