重叠“映射”输出

Question

考虑到输入、数据编织和输出，我想知道为什么在"apple“数组元素中看到”香蕉“的引用。例如，在附带的屏幕截图中，我突出了一个部分，我希望看到的是“苹果-1”而不是“香蕉-苹果-1”。我将在这篇文章中附上输入、数据编织和文本格式的输出。

输入：

{
    "apple":{
        "options":[
            {
                "id": "1",
                "name": "apple-one"
            },
            {
                "id": "2",
                "name": "apple-two"
            },
            {
                "id": "3",
                "name": "apple-three"
            }
        ]
    },
    "banana":{
        "options":[
            {
                "id": "4",
                "name": "banana-four"
            },
            {
                "id": "5",
                "name": "banana-five"
            },
            {
                "id": "6",
                "name": "banana-six"
            }
        ]
    },
    "orange":{
        "options":[
            {
                "id": "7",
                "name": "orange-seven"
            },
            {
                "id": "8",
                "name": "orange-eight"
            },
            {
                "id": "9",
                "name": "orange-nine"
            }
        ]
    }
}

数据编织：

%dw 2.0
output application/json
---
payload.apple.options map ($ mapObject ((value, key, index) -> {
    ((key) : "apple-" ++ value) if ((key) as String == "id"),
    ((key) : value ) if ((key) as String != "id")
        }
    )
)

++


payload.banana.options map ($ mapObject ((value, key, index) -> {
    ((key) : "banana-" ++ value) if ((key) as String == "id"),
    ((key) : value ) if ((key) as String != "id")
        }
    )
)

输出：

[
  {
    "id": "banana-apple-1",
    "name": "apple-one"
  },
  {
    "id": "banana-apple-2",
    "name": "apple-two"
  },
  {
    "id": "banana-apple-3",
    "name": "apple-three"
  },
  {
    "id": "banana-4",
    "name": "banana-four"
  },
  {
    "id": "banana-5",
    "name": "banana-five"
  },
  {
    "id": "banana-6",
    "name": "banana-six"
  }
]

尝试使用此方法(您缺少了构建的每个映射输出的())

%dw 2.0
output application/json
---
(payload.apple.options map ($ mapObject ( {
    (($$) : "apple-" ++ $) if (($$) as String == "id"),
    (($$) : $ ) if (($$) as String != "id")
        }
    
)))

++


(payload.banana.options map ($ mapObject ( {
    (($$) : "banana-" ++ $) if (($$) as String == "id"),
    (($$) : $ ) if (($$) as String != "id")
        }
    )
))
