将数组重构为对象Javascript / Nodejs中的对象列表

Question

我想要的输出在这篇文章的底部，我想删除数组并将对象列表放入对象中。

我正在分享我的地图功能，因为我希望里面有一种方法可以获得我想要的输入，而我只是做得不正确。

如果我所做的没有意义，我会喜欢一种更好的方法来处理这些数据。

起始数据(./updatepayloadTEMP.json)

{
 "outputparameters": [
    {
        "name": "0000x0000",
        "filepath": "D:\\Code\\ImageTiling\\6\\0000x0000.png"
    },
    {
        "name": "0000x0001",
        "filepath": "D:\\Code\\ImageTiling\\6\\0000x0001.png"
    },
    {
        "name": "0000x0002",
        "filepath": "D:\\Code\\ImageTiling\\6\\0000x0002.png"
    }
 ]
}

变量

 let UpdatedTaskOutput = fs.readFileSync('./updatepayloadTEMP.json'); 
 let Updatedtaskoutputjson = JSON.parse(UpdatedTaskOutput); 
 var dynamictaskdetails = Updatedtaskoutputjson.outputparameters;

地图功能

   var taskparamscompiled = dynamictaskdetails.map(function (elem) {
   taskname = tasknamefromworkflowdef + elem.name;
   taskparms = taskparamsobj;
   return {
    [taskname]: taskparms,
   };
  });

我目前得到的taskparamscompiled

 [
 {
   process0000x0000: {
    tr: 16,
    tc: 16,
    ofr: 16,
    ofc: 16,
    outfile: '"D:\\Code\\Process\\1"',
   },
  },
{
 process0000x0001: {
   tr: 16,
   tc: 16,
   ofr: 16,
   ofc: 16,
   outfile: '"D:\\Code\\Process\\1"',
  },
},
{
 process0000x0002: {
   tr: 16,
   tc: 16,
   ofr: 16,
   ofc: 16,
   outfile: '"D:\\Code\\Process\\1"',
 },
},
];

我想要什么

 {
   "process0000x0000": {
   "tr": 16,
   "tc": 16,
   "ofr": 16,
   "ofc": 16,
   "outfile": '"D:\\Code\\Process\\1"'
 },

    "process0000x0001": {
   "tr": 16,
   "tc": 16,
   "ofr": 16,
   "ofc": 16,
   "outfile": '"D:\\Code\\Process\\1"'
 },
 "process0000x0002": {
   "tr": 16,
   "tc": 16,
   "ofr": 16,
   "ofc": 16,
   "outfile": '"D:\\Code\\Process\\1"'
 },
}

我错过了一些东西，更新： 我现在需要像这样将文件路径( "filepath": "D:\\Code\\ImageTiling\\6\\0000x0000.png") 放入进程对象中

process0000x0000: {
   filepath: "D:\\Code\\ImageTiling\\6\\0000x0000.png" 
    tr: 16,
    tc: 16,
    ofr: 16,
    ofc: 16,
    outfile: '"D:\\Code\\Process\\1"',
   }

Array.prototype.map() 将返回一个数组。您可能想使用Array.prototype.reduce()。 https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce

我认为这会给你想要的输出

const dynamictaskdetails = [
  {
    name: '0000x0000',
    filepath: 'D:\\Code\\ImageTiling\\6\\0000x0000.png'
  },
  {
    name: '0000x0001',
    filepath: 'D:\\Code\\ImageTiling\\6\\0000x0001.png'
  },
  {
    name: '0000x0002',
    filepath: 'D:\\Code\\ImageTiling\\6\\0000x0002.png'
  }
];

const taskparamsobj = {
  tr: 16,
  tc: 16,
  ofr: 16,
  ofc: 16,
  outfile: 'D:\\Code\\Process\\1'
};

const taskparamscompiled = dynamictaskdetails.reduce((accumulator, elem) => {
  const taskname = 'process' + elem.name;
  return {
    ...accumulator,
    [taskname]: taskparamsobj,
  };
}, {});

console.log(taskparamscompiled);

这导致以下输出：

{
  process0000x0000: { tr: 16, tc: 16, ofr: 16, ofc: 16, outfile: 'D:\\Code\\Process\\1' },
  process0000x0001: { tr: 16, tc: 16, ofr: 16, ofc: 16, outfile: 'D:\\Code\\Process\\1' },
  process0000x0002: { tr: 16, tc: 16, ofr: 16, ofc: 16, outfile: 'D:\\Code\\Process\\1' }
}
