Jolt 转换 - 即使对象为空也保留 JSON 结构

Question

我有这样的输入json 输入json 1

  {
  "globalRoute": [
    {
      "id": 527763,
      "attributes": {
        "arrival": {
          "date": "2024-03-18T15:23:00.000Z",
          "timezone": "America/New_York"
        }
      },
      "_operation": 1
    }
  ]
}

预期输出

{
  "global_route" : {
    "ship_locations" : [ {
      "global_ship_location_id" : 527763,
      "attributes" : {
        "arrival" : {
          "date" : "2024-03-18T15:23:00.000Z",
          "timezone" : "America/New_York"
        }
      },
      "_operation" : 1
    } ]
  }
}

我已经编写了适合此用例的震动规范。

震动规格

[
  {
    "operation": "shift",
    "spec": {
      "globalRoute": {
        "*": {
          "id": "global_route.ship_locations[&1].global_ship_location_id",
          "attributes": {
            "arrival": {
              "date": "global_route.ship_locations[&3].attributes.arrival.date",
              "timezone": "global_route.ship_locations[&3].attributes.arrival.timezone"
            },
            "departed": {
              "date": "global_route.ship_locations[&3].attributes.departed.date",
              "timezone": "global_route.ship_locations[&3].attributes.departed.timezone"
            }
          },
          "_operation": "global_route.ship_locations[&1]._operation"
        }
      }
    }
  }
]

现在输入Json 2

输入json 1

{
  "globalRoute": [
    {
      "id": 527763,
      "attributes": {
        "arrival": {
        }
      },
      "_operation": 1
    }
  ]
}

预期产出

{
  "global_route" : {
    "ship_locations" : [ {
      "global_ship_location_id" : 527763,
      "attributes" : {
        "arrival" : {
        }
      },
      "_operation" : 1
    } ]
  }
}

但是我当前的震动规范正在删除属性对象。如果传递的是空json，如何保持原样。 请帮助我正确的颠簸规范，以便如果我在属性中传递空 json，它应该支持，否则我们传递的数据应该被转换..

使用以下规格，希望对您有所帮助

[
  {
    "operation": "shift",
    "spec": {
      "globalRoute": {
        "*": {
          "id": "global_route.ship_locations[#3].global_ship_location_id",
          "*": "global_route.ship_locations[#3].&"
        }
      }
    }
  }
]
