将复杂对象转换为数组

Question

响应数据是一个长而复杂的对象，看起来像这样：

{
    "Frozen Products": [
        {
            "_id": "6181849285e8d8f86be2d9df",
            "name": "Peas (800g)",
            "category_id": "6181841060c425f76e57b603",
            "slug": "vegetables",
            "quantity": 16,
            "price": {
                "amount": 3.00
            },
            "thumbnail":"URI ...",,
            "images": [
                "URI ...",
            ],
            "synonyms": [
                "Veggies"
            ],
        },

//etc for many key/values inside this object ..
        
}

我需要访问信息并显示一个类别（“本例中为冻结产品”）及其下的所有产品名称和图像。

但是我认为我需要通过它们的索引（例如数据[0]）而不是密钥名称通过循环访问每个密钥/值对，因为它们密钥是由API动态创建的。那么我如何将其更改为：

{
   [ "Frozen Products": [
        {
            "_id": "6181849285e8d8f86be2d9df",
            "name": "Peas (800g)",
            "category_id": "6181841060c425f76e57b603",
            "slug": "vegetables",
            "quantity": 16,
            "price": {
                "amount": 3.00
            },
            "thumbnail":"URI ...",,
            "images": [
                "URI ...",
            ],
            "synonyms": [
                "Veggies"
            ],
        },
   ]

Answer 1

您可以在迭代器中使用for遍历对象。不管关键名称是什么

for(key in object) {
  let value = object[key];
}

Answer 2

我想你需要这样的东西：

let data = {
    "Frozen Products": [
        {
            "_id": "6181849285e8d8f86be2d9df",
            ...
        }
    ],
    "Another Category": [...]    
}

let categories = Object.keys(data).map((key) => ({categoryName: key, products: data[key]}));
