json - 使用 jq 附加 JSON 对象

Question

我在 JSON 结构下面

{

    "a": "aVal",
    "x": {
      "x1": "x1Val",
      "x2": "x2Val"
    }
    "y": {
      "y1": "y1Val"
    }
}

我想将 "x3": "x3Val","x4": "x4Val" 添加到 x 。所以输出应该是

{
    ...
    "x": {
      ....
      "x3": "x3Val",
      "x4": "x4Val",
    }
    ...
}

是否可以使用 jq ？

Answer 1

当然， jq 非常简单:

jq '.x += {"x3": "x3Val","x4": "x4Val"}' file.json

输出:

{
  "a": "aVal",
  "x": {
    "x1": "x1Val",
    "x2": "x2Val",
    "x3": "x3Val",
    "x4": "x4Val"
  },
  "y": {
    "y1": "y1Val"
  }
}
