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"
}

但是再次，我需要根据我得到的输出json将其转换为旧的json，为此，我必须将输出json的键与类Transformation中的值进行匹配，然后按如下所示重新构建旧的json。

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

下面，我给出了上面用于转换输入到输出json的代码。但如上所述，我需要再次输出json以输入json。

我必须在相同的Tranformation类中进行操作，需要帮助。预先感谢。

场景：休息服务>>> JSON

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

转换json（因为我无法将字段名称显示为error_description，应该为Description），并在ui中以表格形式显示为可编辑字段     再次编辑数据并将json发送到休息服务

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

但是现在json已转换，因此休息服务将不再需要。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，因为它来自第三方。

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);
