azure devops - 如何使用环境变量在任务中创建新变量？

Question

我可以在任务中获取新的字符串变量但是如果这个新变量里面有环境变量，就会失败我需要在任务中使用 curl 来组合 API 和环境变量以获取新变量。

For Simple Example
//get string variable in task it work
- task: Bash@3
  displayName: foovariable
  inputs:
    targetType: 'inline'
    script: |
      FOO="FOOTEST"
      echo "##vso[task.setvariable variable=FOO]$FOO"
- task: Bash@3
  displayName: echofoo
  inputs:
    targetType: 'inline'
    script: |
      echo "$(FOO)"
      //print FOOTEST

//string with variables in new variables then it will fail
variables:
  NAME: Eddy

steps:
- task: Bash@3
  displayName: foovariable
  inputs:
    targetType: 'inline'
    script: |
      Hello="Hi $(NAME)"
      echo "##vso[task.setvariable variable=HELLO]$HELLO"
- task: Bash@3
  displayName: echofoo
  inputs:
    targetType: 'inline'
    script: |
      echo "$(Hello)"
      //I Need it to show "Hi Eddy"

请帮我修改语法谢谢

你可以试试不把调用的环境变量放在双引号里。像这样：

- task: Bash@3
  displayName: foovariable
  inputs:
    targetType: 'inline'
    script: |
      Hello="hi "$NAME
      echo "##vso[task.setvariable variable=HELLO]$Hello"
- task: Bash@3
  displayName: echofoo
  inputs:
    targetType: 'inline'
    script: |
      echo "$(Hello)"

在echofoo步骤可以看到，可以成功打印$(Hello):
