使用输入 JSON 的多种组合来扁平化复杂的嵌套 JSON

Question

我正在尝试编写一个规范来使用摇动变换进行以下变换。我需要将嵌套 JSON 转换为平面 JSON

我在将嵌套 JSON 转换为平面 JSON 时遇到一些麻烦，我已经查看了示例，但没有进一步了解上面提到的内容。我需要使用 JOLT 规范来转换 JSON 结构。我使用 https://jolt-demo.appspot.com 来测试以下内容。

输入1 销售区域是列表的情况下，没有嵌套的合作伙伴功能

{
  "CustomerMaster": {
    "Rootnode": {
      "KUNNR": "0006503338",
      "NAME1": "Schwarz Unternehmens Treuhand KG",
      "LAND1": "DK",
      "SalesArea": [
        {
          "VKORG": "1301",
          "VTWEG": "10",
          "SPART": "00"
        },
        {
          "VKORG": "1501",
          "VTWEG": "10",
          "SPART": "00"
        }
      ],
      "Indicator": "",
      "TimeStamp": "2024-12-18T14:04:40Z"
    }
  }
}

} ]

输入2 销售区域不是列表且一个元素可以包含合作伙伴功能列表的情况

          }
        ]
      }
    }
  }
}

Answer 1

您可以尝试使用移位操作将嵌套的 JSON 结构映射到所需的平面结构，同时迭代 SalesArea 列表。以下是适合您的用例的 JOLT 规格： [ { “操作”：“转移”， “规格”：{ “客户大师”：{ “根节点”：{ "KUNNR": "[&1].KUNNR", "NAME1": "[&1].NAME1", "LAND1": "[&1].LAND1", "指标": "[&1].指标", "时间戳": "[&1].时间戳", “销售区域”：{ “”：{ "VKORG": "[&2].[&1].VKORG", "VTWEG": "[&2].[&1].VTWEG", "SPART": "[&2].[&1].SPART" } } } } } }, { “操作”：“转移”， “规格”：{ “”：{ “*”：“” } } } ]
