Question

拥有以下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＆＃34; info＆＃34;他们实际上将键：值对标记为＆＃34;键＆＃34;：＆＃34; problem_type＆＃34;和＆＃34;价值＆＃34;：＆＃34; PAN＆＃34;然后＆＃34; valueCaption＆＃34;：＆＃34; PAN＆＃34; ＆＃34; keyCaption＆＃34;：＆＃34;类别＆＃34;。我需要做的是重新映射文件，以便在此示例中，它显示为＆＃34; problem_type＆＃34;：＆＃34; PAN＆＃34; ＆＃34;类别＆＃34;：＆＃34; PAN＆＃34;。以这种方式迭代输出以重新映射键：值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

以下是使用jq

的Update assignment |=解决方案

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

示例运行（假设data.json中的数据）

$ 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"
      }
    ]
  }
]
