我正在尝试对这种json进行颠簸转换:

{
  "id" : "6aa0734f-6d6a-4b95-8a2b-2dde346f9df7",
  "ts" : 1583684304500000,
  "measurements" : {
    "A4" : {
      "value" : 164341584
    },
    "A5" : {
      "value" : -20486832
    }
}}

最后我需要得到这样的东西:

{"id" : "6aa0734f-6d6a-4b95-8a2b-2dde346f9df7",
"ts" : 1583684304500000,
"A4" : 164341584,
"A5" : -20486832
}

我需要使用哪种规格?

非常感谢!

答案 0 :(得分:1)

震动规格:

[
  {
    "operation": "shift",
    "spec": {
      "ts": "ts",
      "id": "id",
      "measurements": {
        "*": {
          "*": {
            "@": "&2"
          }
        }
      }
    }
  }
]

输入:

{
  "id": "6aa0734f-6d6a-4b95-8a2b-2dde346f9df7",
  "ts": 1583684304500000,
  "measurements": {
    "A4": {
      "value": 164341584
    },
    "A5": {
      "value": -20486832
    }
  }
}

输出:

{
  "ts" : 1583684304500000,
  "id" : "6aa0734f-6d6a-4b95-8a2b-2dde346f9df7",
  "A4" : 164341584,
  "A5" : -20486832
}
