javascript - 读取.log文件并转换为json

Question

我有 .log 文件，我需要在 javascript 中获取该文件并将其转换为 JSON。我试试这个

var j= readTextFile("log991/sensorData.log");
        console.log(j);
        var jsonnn = JSON.stringify(j);  
        console.log(jsonnn);

但我只在控制台日志中获取路径。有什么办法可以做到这一点吗？

这就是 .log 文件的样子

2018-04-03 15:47:58,873 INFO log(17) batteryCurrent=-0.45, solarCurrent=3.27, 
hybridCurrent=0, batteryVoltage=12.88, solarVoltage=13.09
2018-04-03 15:48:00,074 INFO log(17) batteryCurrent=-0.45, solarCurrent=3.27, 
hybridCurrent=0, batteryVoltage=12.88, solarVoltage=13.09
2018-04-03 15:48:01,274 INFO log(17) batteryCurrent=-0.4, solarCurrent=3.28, 
hybridCurrent=0, batteryVoltage=12.89, solarVoltage=13.1

谢谢

尝试此代码使用同步版本

const fs = require('fs');
var text = fs.readFileSync('/somepath/a.txt','utf8')
console.log (text)

尝试将这段代码转换为json

const fs = require('fs');
var text = fs.readFileSync('/somepath/a.txt','utf8')
array = text.split("\n")
var dataArray = [];
for(var i=0; i<array.length; i++){
  if(array[i] == ''){continue}
  let tempArray = []
  tempArray = array[i].split(",");
  dataArray.push(tempArray)
};

json = {};
var c = 1;
dataArray.forEach( (e1) =>{
  isdate = true;
  var tempjson = {};
  e1.forEach( (e2) =>{
    var key;
    if(isdate )  {
        key = 'date';
        tempjson[key] = e2;
        isdate = false;
    }
    else if(e2.includes("batteryCurrent")){
        key = "batteryCurrent";
        tempjson[key]= e2.split("batteryCurrent=")[1]
    }
    else{
        var arr = e2.split("=");
        key  = arr[0].trim();
        tempjson[key] = arr[1];
    }
  })
  json[c] = tempjson;
  c++
});

console.log(json)
