从嵌套对象参数中检索值

Question

我的问题密切相关，但我似乎没有帮助我:( 如何从嵌套对象检索值？

我正在尝试循环浏览我作为参数的对象，我以默认值为例，该对象中的值也是对象。

我有一个模板：

parameters: 
  - name: fruits
    type: object
    default:     
      - Banana:
          name: " acuminata"
          url: "www.banana.com/ acuminata"
      - Apple:
          name: "jonaGold"
          url: "www.apple.com"


steps:

- bash: echo ${{parameters.fruits[0].url}}    



- ${{ each fruit in parameters.fruits }}:
  - script: echo ${{fruit.name}}

第二个bash均可使用。

第一个bash和

Answer 1

我刚刚找到了解决方案。另一个线程确实提供了答案，我只需要更好地阅读：P。

您可以使用“value”关键字访问这些值。我还删除了关键字之前的“-”，因此它不再是数组。代码现在看起来像这样：

parameters: 
  - name: fruits
    type: object
    default:     
      Banana:
        name: " acuminata"
        url: "www.banana.com/ acuminata"
      Apple:
        name: "jonaGold"
        url: "www.apple.com"


steps:
   

- ${{ each fruit in parameters.fruits }}:
  - script: echo ${{fruit.value.name}}

我得到这个输出：

我还没有让第一个工作正常，但我的项目并不真正需要这个

- bash: echo ${{parameters.fruits[0].value.url}}
