JQ如何将数组中的多个对象合并为一个 [英] JQ how to merge multiple objects in an array into one

问题描述

我的问题将在下面提到. 我学会了更多地使用数组，但是它也会使事情搞砸.

A little more sophisticated as my question mentioned below. I learned to use arrays more, but it screws things up too.

输入:

{
  "a": [
    {
      "b": "c",
      "d": "e"
    },
    {
      "b": "f",
      "d": "g"
    }
  ],
  "h": [
    {
      "b": "c",
      "i": "j"
    },
    {
      "b": "f",
      "i": "k"
    }
  ]
}

所需的输出:

{
  "l": [
    {
      "b": "c",
      "d": "e",
      "i": "j"
    },
    {
      "b": "f",
      "d": "g",
      "i": "k"
    }
  ]
}

基于 JQ我尝试过的方法将多个对象合并为一个

{ x: [ inputs | .a[] | { (.h[]): .i } ] | add}

推荐答案

简单解决方案的关键是transpose:

The key to a simple solution is transpose:

[.a, .h]
| transpose
| map(add)
| {l: .}
