javascript - 如何解析 json 关键点文字

Question

我有这个 JSON 对象，它是一个动态生成的对象，我无法控制它如何格式化为 json。问题是 json 看起来像这样:

{
  "id": "def",
  "name": "def",
  "description": {},
  "description.shortened": "def",
  "description.extended": "def",
  "type": "EDIBLE_BOUQUET",
  "image": {},
  "image.name": "def",
  "image.slug": "def",
  "image.extension": "PNG",
  "state": "FEATURED",
  "stock": "def"
}

我将如何将其转换为:

{
  "id": "def",
  "name": "def",
  "description": {
    "shortened": "def",
    "extended": "def"
  },
  "type": "EDIBLE_BOUQUET",
  "image": {
    "name": "def",
    "slug": "def",
    "extension": "PNG"
  },
  "state": "FEATURED",
  "stock": "def"
}

Answer 1

let obj = {
  "id": "def",
  "name": "def",
  "description": {},
  "description.shortened": "def",
  "description.extended": "def",
  "type": "EDIBLE_BOUQUET",
  "image": {},
  "image.name": "def",
  "image.slug": "def",
  "image.extension": "PNG",
  "state": "FEATURED",
  "stock": "def"
}

const transformObj = obj => {
  return Object.keys(obj).reduce((acc, key) => {
   if(key.indexOf('.') >= 0){
     const [parentKey, childKey] = key.split('.');
     acc[parentKey] = acc[parentKey] || {};
     acc[parentKey][childKey] = obj[key];
   } else {
     acc[key] = obj[key];
   }
   return acc;
  }, {});
}
   
console.log(transformObj(obj));
