通过Jolt json转换，是否可以将值复制到两个不同的属性中? [英] With Jolt json transformation, is it possible to copy a value into two different attributes?

问题描述

我正在尝试通过Jolt转换进行一些非常简单的操作，但是却很难使其正常工作.

Am trying something very simple with Jolt transformation but struggling to get it to work.

如果我输入类似:

{
    "id": "54436001"
}

我希望输出为:

{
  "mediaId" : "54436001",
  "events" : {
    "mediaId" : "54436001"
  }
}

将值复制到两个不同的属性.我很想尝试像这样的规范，但是显然不是因为重复的密钥.

Which is copying a value to two different attributes. I would be tempted to try spec like this to work, but obviously it doesn't because of duplicate key.

[
  {
    "operation": "shift",
    "spec": {
      "id": "mediaId",
      "id": "events.mediaId"
    }
  }
]

Jolf变换有可能吗?

Is this possible with Jolf transformation?

推荐答案

是

规格

[
  {
    "operation": "shift",
    "spec": {
      "id": ["mediaId", "events.mediaId"]
    }
  }
]

这个想法是，如果您想移位以将一个值写入输出中的两个位置，请使用规范右侧的一个数组.

The idea is if you want shift to write a value to two locations in the output, use an array on the right hand side of the spec.
