Question

输入JSON在下面 [ { “ correlationId”：“ 12345”， “ payloadFormat”：“金钱”， “有效载荷”：{ “ DE61”：“ 000001000150084063368”， “ location”：“ south”， “ name”：“ Dallas”， “ pop”：“ 2M” } }， { “ correlationId”：“ ed1e3”， “ payloadFormat”：“现金”， “有效载荷”：{ “ DE”：“ 000001000150084063368”， “ location”：“ west”， “ name”：“ LosAngeles”， “ pop”：“ 4M” } } ]

需要按照以下输出消息进行转换。

[ {

"payload": {
"correlationId": "12345",
"payloadFormat": "Money",
  "DE61SF1": "00",
  "DE61SF2": "100015008",
  "DE61SF3": "4063368",
  "location": "south",
  "name": "Dallas",
  "pop": "2M"
}

}， {

"payload": {
"correlationId": "ed1e3",
 "payloadFormat": "Cash",
  "DE61SF1": "00",
  "DE61SF2": "100015008",
  "DE61SF3": "4063368",
  "location": "west",
  "name": "LosAngeles",
  "pop": "4M"
}

} ]

检查此规格

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "@": "&",
        // Shift all the DE nodes to a same named node.
        // Here it is moved as TMPDE
        "payload": {
          "DE|DE61": "&2.payload.TMPDE"
        }
      }
    }
  }, {
    "operation": "modify-default-beta",
    "spec": {
      "*": {
        "payload": {
          "DE61SF1": "=substring(@(1,TMPDE), 2, 4)",
          "DE61SF2": "=substring(@(1,TMPDE), 5, 14)",
          "DE61SF3": "=substring(@(1,TMPDE), 14, 21)"
        }
      }
    }
  }, {
    "operation": "shift",
    "spec": {
      "*": {
        "correlationId": "[&1].payload.correlationId",
        "payloadFormat": "[&1].payload.payloadFormat",
        "payload": {
          "DE61SF1": "[&2].payload.DE61SF1",
          "DE61SF2": "[&2].payload.DE61SF2",
          "DE61SF3": "[&2].payload.DE61SF3",
          "location": "[&2].payload.location",
          "pop": "[&2].payload.pop",
          "name": "[&2].payload.name"
        }
      }
    }
  }
]

需要JOLT规范才能将源JSON格式转换为所需的JSON格式
