如何使用 dataweave 操作输入以获得所需的输出？

Question

输入Json { “姓名”： { “显示值”：空， “价值”：“EQ-10186735” }, “SP_Altitude__c”：{ “显示值”：空， “价值”：“ALT001” }, “SP_Batch_Number__c”：{ “显示值”：空， “值”：“Batch_number_001” }, “SP_Classification__c”：{ “显示值”：空， “价值”：“产品” }, “SP_Current_Equipment_Partner__c”：{ “显示值”：空， “值”：“Eqpartner__1” }, “SP_Current_Equipment_Partner__r”：{ “显示值”：“Eqpartner__1” “价值”： ”” }, “SP_Delivery_Date__c”：{ “显示值”：“2016 年 9 月 2 日”， “价值”：“2016-09-02” }, “SP_Delivery_Note__c”：{ “显示值”：空， “值”：“82849654” }, “SP_End_of_Commissioning__c”：{ “显示值”：空， “值”：“2019-03-02” }, “SP_Product_Number__c”：{ “显示值”：空， “值”：“1MV4567-6BJ60-4BD0-Z” } }

输出 [ “名称”：“EQ-10186735”， "SP_Altitude__c": "ALT001", "SP_Batch_Number__c": "Batch_number_001", "SP_Classification__c": "产品", "SP_Current_Equipment_Partner__c": "Eqpartner__1", "SP_Current_Equipment_Partner__r": "Eqpartner__1", "SP_Delivery_Date__c": "2016-09-02", "SP_Delivery_Note__c": "82849654", "SP_End_of_Commissioning__c": "2019-03-02" “SP_Product_Number__c”：“1MV4567-6BJ60-4BD0-Z” ]

Answer 1

给定的输出是一个数组，但它有 key/value 对。所以我假设输出类型是 Object.

如果是这样，您可以使用 mapObject。

payload mapObject ((item, key) -> {
    (key): item.value
} )

输出是

{
  "Name": "EQ-10186735",
  "SP_Altitude__c": "ALT001",
  "SP_Batch_Number__c": "Batch_number_001",
  "SP_Classification__c": "Products",
  "SP_Current_Equipment_Partner__c": "Eqpartner__1",
  "SP_Current_Equipment_Partner__r": "",
  "SP_Delivery_Date__c": "2016-09-02",
  "SP_Delivery_Note__c": "82849654",
  "SP_End_of_Commissioning__c": "2019-03-02",
  "SP_Product_Number__c": "1MV4567-6BJ60-4BD0-Z"
}

您还可以使用 pluck 获取对象数组，如下所示

payload pluck ((item, key) -> {
    (key): item.value
})

输出：-

[
  {
    "Name": "EQ-10186735"
  },
  {
    "SP_Altitude__c": "ALT001"
  },
  {
    "SP_Batch_Number__c": "Batch_number_001"
  },
  {
    "SP_Classification__c": "Products"
  },
  {
    "SP_Current_Equipment_Partner__c": "Eqpartner__1"
  },
  {
    "SP_Current_Equipment_Partner__r": ""
  },
  {
    "SP_Delivery_Date__c": "2016-09-02"
  },
  {
    "SP_Delivery_Note__c": "82849654"
  },
  {
    "SP_End_of_Commissioning__c": "2019-03-02"
  },
  {
    "SP_Product_Number__c": "1MV4567-6BJ60-4BD0-Z"
  }
]

Answer 2

查看请求和期望的响应，键的值深一层。我使用在线 dw playground 传递您的输入请求，这里是获得所需输出的代码。

   %dw 2.0 output application/json
  payload mapObject ((value, key, index) -> {(key):value.value} )
