如何使用Node.js解析具有JSON对象数组的文件？

由 发布于

我有一个项目，我想从具有重复属性的json对象数组的文件中获取JSON数据：

一些文件：（每个对象在一行中，为简单起见，我对其进行了格式化）

{
   "A":"ALL",
   "B":"3349256522",
   "Location":{

      "Country":"USA"
   },
   "EffectiveDate":"2020-03-04T14:15:52.063Z",
   "Demographic":{
      "Q":"done",
      "G":"ok",
      "AppVersion":"1.3.4",
   },
   "ApplicationId":"92398723892937",
   "Id":"23232993939333",
   "CreationDate":"2020-03-04T14:15:52.063Z"
}

{
   "A":"NONE",
   "B":"8469256522",
   "Location":{
      "Country":"SPAIN"
   },
   "EffectiveDate":"2020-03-04T14:15:52.063Z",
   "Demographic":{
      "Q":"done",
      "G":"ok",
      "AppVersion":"1.3.5",
   },

   "ApplicationId":"92398723892937",
   "Id":"23232993939333",
   "CreationDate":"2020-03-09T14:15:52.063Z"
}

{
   "A":"ALL",
   "B":"8469256522",
   "Location":{

      "Country":"USA"
   },
   "EffectiveDate":"2020-03-04T14:15:52.063Z",
   "Demographic":{
      "Q":"done",
      "G":"ok",
      "AppVersion":"1.3.4",
   },

   "ApplicationId":"92398723892937",
   "Id":"23232993939333",
   "CreationDate":"2020-03-11T14:15:52.063Z"
}

我想获取某些特定项目的统计信息，例如Country和AppVersion。 如何使用NodeJ处理它以产生以下输出：

{
   "stats":{
      "Country":{
         "USA":"2",
         "SPAIN":"1"
      },
      "AppVersion":{
         "1.3.4":"2",
         "1.3.5":"1"
      }
   }
}
