Mule 嵌套循环以生成json数组

我需要为输入中的每个对象在json数组中输入两个对象

为此，我编写了以下代码：

%dw 2.0
output application/csv
var categoryList = ["Business","Authorization"]
---
payload map((payload01,indexOfPayload01)->
categoryList map((payload02,indexOfPayload02)->
    {
    "Name": payload01.Name,
    "Category":payload02,
    "Code":"Customer",
    "Percentage":null,
    "End Tag": "End"
    })
)

我的输出是：

[
  [
    {
      "Name": "Desc 1",
      "Category": "Business",
      "Code": "Customer",
      "Percentage": null,
      "End Tag": "END"
    },
    {
      "Name": "Desc 1",
      "Category": "Authorization",
      "Code": "Customer",
      "Percentage": null,
      "End Tag": "END"
    }
  ],
  [
    {
      "Name": "Desc 2",
      "Category": "Business",
      "Code": "Customer",
      "Percentage": null,
      "End Tag": "END"
    },
    {
      "Name": "Desc 2",
      "Category": "Authorization",
      "Code": "Customer",
      "Percentage": null,
      "End Tag": "END"
    }
  ]
]

但我希望将这些值作为单个json数组。在这里，数据被分离为两个对象。我的预期产出：

[
    {
      "Name": "Desc 1",
      "Category": "Business",
      "Code": "Customer",
      "Percentage": null,
      "End Tag": "END"
    },
    {
      "Name": "Desc 1",
      "Category": "Authorization",
      "Code": "Customer",
      "Percentage": null,
      "End Tag": "END"
    },
    {
      "Name": "Desc 2",
      "Category": "Business",
      "Code": "Customer",
      "Percentage": null,
      "End Tag": "END"
    },
    {
      "Name": "Desc 2",
      "Category": "Authorization",
      "Code": "Customer",
      "Percentage": null,
      "End Tag": "END"
    }
]

我怎样才能做到这一点？不用说，我对骡子还不熟悉

谢谢，

您可以使用我在本例中显示的flatMap，或者将结果展平，如例2所示

%dw 2.0
output application/csv
var categoryList = ["Business","Authorization"]
---
payload flatMap((payload01,indexOfPayload01)->
categoryList map((payload02,indexOfPayload02)->
    {
    "Name": payload01.Name,
    "Category":payload02,
    "Code":"Customer",
    "Percentage":null,
    "End Tag": "End"
    })
)

这个例子展示了如何使用flattn

%dw 2.0
output application/csv
var categoryList = ["Business","Authorization"]
---
flatten(payload map((payload01,indexOfPayload01)->
categoryList map((payload02,indexOfPayload02)->
    {
    "Name": payload01.Name,
    "Category":payload02,
    "Code":"Customer",
    "Percentage":null,
    "End Tag": "End"
    })
))

谢谢你，马查瓦。压扁是我们所缺少的。谢谢马查瓦尔。平坦是所缺少的一切。
