azure - 在 AzurePowerShellV5 内联脚本中引用 yaml 变量

Question

我有一个 Azure DevOps yaml 管道，看起来（有点像）是这样的：

variables:
  MyVar: Test

Steps:
  - task: AzurePowerShell@5
    displayName: 'Test variables from yml file'
    inputs:
      azureSubscription: MyServiceConnection
      ScriptType: InLineScript
      InLine: |
        Write-Host "I really want to see the values from the variables in the yml file here"
        Write-Host "parameters from the yml file would be great too"
        Write-Host "But what would I write to do that?"
        Write-Host "$(MyVar) <- Nothing here"
        Write-Host "$(variables.MyVar) <- Nothing here"
        Write-Host "$DoesThisWork <- Nothing here"
        Write-Host "$OrThis <- Nothing here"
      env:
        DoesThisWork: $(MyVar)
        OrThis: $(variables.MyVar)

如何在 InLine 脚本中使用 MyVar？

我把它精简到最简单的，它工作得很好：

pool: 
  vmImage: 'windows-latest'

variables: 
  myVar: test value

steps:
  - powershell: Write-Host "$(myVar)"

生成：

我修改了您的示例以删除env未编译的块，并删除不正确的变量引用：

pool: 
  vmImage: 'windows-latest'

variables: 
  myVar: test value

steps:
- task: AzurePowerShell@5
  inputs:
    azureSubscription: 'My Service Connection Name'
    ScriptType: 'InlineScript'
    Inline: |
      Write-Host "I really want to see the values from the variables in the yml file here"
            Write-Host "parameters from the yml file would be great too"
            Write-Host "But what would I write to do that?"
            Write-Host "$(MyVar) <- Nothing here"
    azurePowerShellVersion: 'LatestVersion'

并得到：

它没有通过第一个，因为语法$(variables.MyVar)无效。语法如下：

• 编译时间（只能在声明变量的文件中使用，而不是像模板这样的嵌套文件）：${{ variables.MyVar }}
• 运行时（任务执行前）：$(MyVar)- 如果为空，则扩展为“$(MyVar)”
• 运行时（为条件设计，或默认值导致问题）：$[variables.MyVar]- 如果为空，则扩展为空字符串

我想知道缺少 Azure Powershell 版本是否是您的问题的一部分？
