javascript - 根据我的项目中的以下要求转换json

Question

class Transformation {
  constructor() {
    this.colHeaders = {
      error_description: "Description",
      error_status: "Status",
      error_code: "Error Code"
    };
  }

  getColHeader() {
    return this.colHeaders;
  }
}

var jsonData = {
  error_description: "Already Rejected",
  error_status: "Faliure",
  error_code: "401"
};
var clmDetails = new Transformation();
var obj = clmDetails.getColHeader();
var json_conversion = {};
for (var key in jsonData) {
  if (jsonData.hasOwnProperty(key)) {
    var k = obj[key.toLowerCase().replace(/\s/g, "_")];
    var val = jsonData[key];
    json_conversion[k] = val;
  }
}

console.log(json_conversion);

    Input Json:
{
  "error_description": "Already Rejected",
  "error_status": "Faliure",
  "error_code": "401"
}


output Json I am getting:
O/P:
{
  "Description": "Already Rejected",
  "Status": "Faliure",
  "Error Code": "401"
}

但是我再次需要根据我得到的输出 json 将其转换为旧 json，为此我必须将输出 json 的键与类 Transformation 中的值相匹配，然后像下面这样改革旧 json。

Expected Output:
 {
      "error_description": "Already Rejected",
      "error_status": "Faliure",
      "error_code": "401"
 }

下面我给出了上面的代码，用于将输入转换为输出 json。但我需要再次输出 json 来输入 json，如上所述。

我必须在同一个转换类中执行此操作，需要帮​​助。提前致谢。

场景:休息服务 >>> JSON

{
      error_description: "Already Rejected",
      error_status: "Faliure",
      error_code: "401"
    }

transforming json(because I cant show the field name as error_description,It should be Description) and showing as form in ui as editable fields again editing data and sending the json to rest service

{
  "Description": "Already Rejected",
  "Status": "Faliure",
  "Error Code": "401"
}

但是现在 json 已经被转换，所以休息服务不会采取。所以我再次需要 json 作为

{
      error_description: "Already Rejected",
      error_status: "Faliure",
      error_code: "401"
    }

我无法在 Rest 服务中添加 json 转换属性，因为它来自第 3 方。

class Transformation {
  constructor() {
    this.colOutHeaders = {
      error_description: "Description",
      error_status: "Status",
      error_code: "Error Code"
    };

    this.colInHeaders = {
      "Description": "error_description",
      "Status": "error_status",
      "Error Code": "error_code"
    };
  }

  getOutHeader() {
    return this.colOutHeaders;
  }

  getInHeader() {
    return this.colInHeaders;
  }
}

function transform(jsonData, obj) {

  var json_conversion = {};
  for (var key in jsonData) {
    if (jsonData.hasOwnProperty(key)) {
      var k = obj[key];
      var val = jsonData[key];
      json_conversion[k] = val;
    }
  }
  
  return json_conversion;
}

var jsonData = {
  error_description: "Already Rejected",
  error_status: "Faliure",
  error_code: "401"
};

var clmDetails = new Transformation();
var obj = clmDetails.getOutHeader();

output = transform(jsonData, obj);
console.log(output);

revertOutput = transform(output, clmDetails.getInHeader());
console.log(revertOutput);

我更新了，请尝试一下可能会有帮助
