js object 方法 交换key值的情况下，保持值不变

/**

• @description: 置换value值
• @param source 接口传入的对象
• @param target 目标置换对象
• 例如：source[target[key]]= target[key]
  source = { x:123,y:456 };
  target = { a:x,b:y};
  变成
  obj = {a:123,b: 456}
  */
  export const ConvertCardInfo = (source: object, target: object) => {
  const obj = Object.keys(target).reduce((newData, key) => {
  let newKey = source[key] || key;
  newData[newKey] = target[key];
  return newData;
  }, {});
  return obj;
  };
