需要 JOLT 规范将源 JSON 格式转换为所需的 JSON 格式

Question

输入 JSON 如下 [ { “correlationId”：“12345”， "payloadFormat": "钱", “有效载荷”：{ "DE61": "000001000150084063368", “位置”：“南”， “名称”：“达拉斯”， “流行”：“2M” } }, { “correlationId”：“ed1e3”， "payloadFormat": "现金", “有效载荷”：{ “德”：“000001000150084063368”， “位置”：“西”， “名称”：“洛杉矶”， “流行”：“4M” } } ]

需要转换成如下输出信息。

[ {

"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"
}

} ]

检查此规范，

[
  {
    "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"
        }
      }
    }
  }
