如何使用 Jolt 展平嵌套 JSON？

Question

您好，我有以下 json，想取消嵌套归档。所以，我有一个旧订单和新订单的产品。 json 可能有更多字段，但嵌套级别保持不变。是否可以通过 Jolt 来做到这一点？ 我可以在输出中包含 new_something 和 old_something 等字段

{
  "data": {
    "new": {
      "orders": {
        "type": "atype",
        "currency": "usd",
        "name": null,
        "code": null,
        "shipped": null,
        "identifier": "some uuid",
        "source": "webshop",
        "productinfo": [
          {
            "pType": "fan",
            "ts": "2024-11-15T13:33:16.047Z",
            "status": null,
            "seller": {
              "identifier": "uuid",
              "internacodes": [
                {
                  "type": "US",
                  "value": "1111"
                },
                {
                  "type": "UUID",
                  "value": "some uuid"
                }
              ]
            }
          },
          {
            "pType": "fan",
            "ts": "2024-11-25T13:33:16.047Z",
            "status": null,
            "seller": {
              "identifier": "uuid",
              "internacodes": [
                {
                  "type": "US",
                  "value": "1111"
                },
                {
                  "type": "UUID",
                  "value": "some uuid"
                }
              ]
            }
          }
        ],
        "unique_num": [
          {
            "type": "UUID",
            "value": "some uuid",
            "ts": "2024-11-13T25:15:47.919Z"
          },
          {
            "type": "product id",
            "value": "23456",
            "ts": "2024-11-22T15:15:46.912Z"
          }
        ]
      }
    },
    "old": {
      "orders": {
        "type": "atype",
        "currency": "usd",
        "name": null,
        "code": null,
        "shippedOffice": null,
        "identifier": "some uuid",
        "source": "webshop",
        "productinfo": [
          {
            "pType": "fan",
            "ts": "2024-11-15T13:33:16.047Z",
            "status": null,
            "seller": {
              "identifier": "uuid",
              "internacodes": [
                {
                  "type": "US",
                  "value": "1111"
                },
                {
                  "type": "UUID",
                  "value": "some uuid"
                }
              ]
            }
          }
        ],
        "unique_num": [
          {
            "type": "UUID",
            "value": "some uuid",
            "ts": "2024-11-13T25:15:47.919Z"
          },
          {
            "type": "product id",
            "value": "23456",
            "ts": "2024-11-22T15:15:46.912Z"
          }
        ]
      }
    }
  }
}

请分享建议和意见。我尝试通过 Jolt 中的硬编码操作，但可能会添加非嵌套字段。嵌套字段保持不变。 我需要这样的输出 -

{

   
    "data.new.orders.type": "atype",
    "data.new.orders.currency": "usd"
    .....
    "data.new.orders.productinfo.seller.identifier": "seller_identifier"
}

嗨，这个规范可以帮助您实现它。

给你一小块有2个字段的：

基本上我会跳过“。”运算符“\”转义字符“\”。

[
  {
    "operation": "shift",
    "spec": {
      "data": {
        "new": {
          "orders": {
            "type": "&3\\.&2\\.&1\\.&",
            "currency": "&3\\.&2\\.&1\\.&"
          }
        }
      }
    }
  }
]
