使用 Mule 3 进行嵌套数组数据转换

Question

我正在尝试在 Mule 3 (DataWeave 1.0) 中转换数据，但没有得到想要的结果。

这是输入负载：

[
  "https://scrum-caller.com/repo/v1/inside#Changes",
  [
    {
      "id": "8db55441-6255-4d24-8d39-658536985214",
      "number": "0w-30",
      "Desc": "maintain"
    }
  ],
  "https://scrum-caller.com/repo/v1/inside#Changes",
  [
    {
      "id": "11111111-6666-2222-3g3g-854712547412",
      "number": "5w-40",
      "Desc": "on prod"
    }
  ],
  "https://scrum-caller.com/repo/v1/inside#Changes",
  [
    {
      "id": "1ab32c5b-ffs3-3243-74fv-3376218042bb",
      "number": "5w-30",
      "Desc": "on test"
    }
  ]
]

我的愿望输出需要像下面这样

{
    "@odata.context": "https://scrum-caller.com/repo/v1/inside#Changes",
    "value": [
        {
      "id": "8db55441-6255-4d24-8d39-658536985214",
      "number": "0w-30",
      "Desc": "maintain"
    },
    {
      "id": "11111111-6666-2222-3g3g-854712547412",
      "number": "5w-40",
      "Desc": "on prod"
    },
    {
      "id": "1ab32c5b-ffs3-3243-74fv-3376218042bb",
      "number": "5w-30",
      "Desc": "on test"
    }
    ]
}

感谢大家的帮助。

假设所有的url都是相同的，因为问题没有提供细节只是一个例子，我只是把第一个元素作为“@odata.context”的输入值，这个值只是过滤掉 non-array 元素并使用 reduce 运算符获取其他元素的单个数组。

%dw 1.0
%output application/json
---
{
  "@odata.context" : payload[0],
  value : payload filter ($ is :array) reduce ($ ++ $$)
}
