使用对象中的值重命名 JSON 键字段

Question

具有以下 json 输出：

[
{
    "id": "47",
    "canUpdate": true,
    "canDelete": true,
    "canArchive": true,
    "info": [
        {
            "key": "problem_type",
            "value": "PAN",
            "valueCaption": "PAN",
            "keyCaption": "Category"
        },
        {
            "key": "status",
            "value": 3,
            "valueCaption": "Closed",
            "keyCaption": "Status"
        },
        {
            "key": "insert_time",
            "value": 1466446314000,
            "valueCaption": "2016-06-20 14:11:54.0",
            "keyCaption": "Request time"
        }

正如您在 "info" 下看到的那样，他们实际上将 key:value 对标记为 "key"："problem_type" 和 "value"："PAN" 和然后 "valueCaption"："PAN" "keyCaption"："Category"。我需要做的是重新映射文件，以便在此示例中显示为 "problem_type"："PAN" 和 "Category"："PAN"。以这种方式遍历输出以重新映射 key:value 对的最佳方法是什么？

需要如何：

[
{
    "id": "47",
    "canUpdate": true,
    "canDelete": true,
    "canArchive": true,
    "info": [
        {
            "problem_type": "PAN",
            "Category": "PAN"
        },
        {
            "status": 3,
            "Status": "Closed"
        },
        {
            "insert_time": 1466446314000,
            "Request time": "2016-06-20 14:11:54.0"
        }

Answer 1

这里是jq solution which uses Update assignment |=

.[].info[] |= {(.key):.value, (.keyCaption):.valueCaption}

样本运行（假设数据在data.json）

$ jq -M '.[].info[] |= {(.key):.value, (.keyCaption):.valueCaption}' data.json
[
  {
    "id": "47",
    "canUpdate": true,
    "canDelete": true,
    "canArchive": true,
    "info": [
      {
        "problem_type": "PAN",
        "Category": "PAN"
      },
      {
        "status": 3,
        "Status": "Closed"
      },
      {
        "insert_time": 1466446314000,
        "Request time": "2016-06-20 14:11:54.0"
      }
    ]
  }
]
