需要使用 JOLT 将 JSON 转换为特定的 JSON

Question

我有以下用户输入 json。 [ { “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” } } ]

我需要在 JOLT Spec 的帮助下转换成下面的输出

[ { “correlationId”：“12345”， "payloadFormat": "钱", “DE61SF1”：“00”， "DE61SF2": "100015008", “DE61SF3”：“4063368”， “位置”：“南”， “名称”：“达拉斯”， “流行”：“2M” }, { “correlationId”：“ed1e3”， "payloadFormat": "现金", “DE61SF1”：“00”， "DE61SF2": "100015008", “DE61SF3”：“4063368”， “位置”：“西”， “名称”：“洛杉矶”， “流行”：“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].correlationId",
        "payloadFormat": "[&1].payloadFormat",
        "payload": {
          "DE61SF1": "[&2].DE61SF1",
          "DE61SF2": "[&2].DE61SF2",
          "DE61SF3": "[&2].DE61SF3",
          "location": "[&2].location",
          "pop": "[&2].pop",
          "name": "[&2].name"
        }
      }
    }
  }
]
