将 JSON 规范化为自定义架构

Question

我有一组具有以下格式的对象

var arr = [
    {
        "productId": "123456",
        "productName": "Test Product 1",
        "description": [
            "This is delicious",
            "Suitable for vegetarian"
        ],
        "attributes": {
            "internalId": "091283"
            "category": "Dairy"
        },
        "order": 1
    }
];

我正在尝试映射到如下所示的内容

[
    [{
        {
            "name": "productId",
            "value": "123456"
        },
        {
            "name": "productName",
            "value": "Test Product 1"
        },
        {
            "name": "description",
            "value": ["This is delicious", "Suitable for vegetarian"]
        },
        {
            "name": "attributes",
            "value": {
                {
                    "name": "internalId",
                    "value": "091283"
                },
                {
                    "name": "category",
                    "value": "Dairy"
                }
            }
        },
        {
            "name": "order",
            "value": 1
        }
    }]
]

在继续之前，我尝试映射简单的属性，现在坚持只获取循环中每个对象的最后一个属性。

假设我不知道传入数据的格式是什么，以及如何将 JSON 对象规范化为我想要的格式？

normalizeJson = (array) => {
        for(i = 0; i < array.length; i++){
            normalizedJson[i] = {};
            Object.keys(array[i]).forEach(key => {
                if (array[i][key] && typeof array[i][key] === "object") {
                    // normalizeJson(obj[key]);
                    // console.log(key + ' is object');
                    return;
                } else {
                    o = {};
                    o["name"] = key;
                    o["value"] = array[i][key];
                    normalizedJson[i] = o;
                    // normalizedJson[i]["name"] = key;
                    // normalizedJson[i].value = array[i][key];
                    // console.log(key);
                    return;
                }
            });
        }

          console.log(normalizedJson);
    };

或者有没有我可以使用的库来实现这一目标？

尝试这个

 var obj = [ { productId: "123456", productName: "Test Product 1", description: ["This is delicious", "Suitable for vegetarian"], attributes: { internalId: "091283", category: "Dairy", }, order: 1, }, ]; function normalizeObject(obj) { var result = []; if (Array.isArray(obj)) { for (let i of obj) { result.push(normalizeObject(i)); } } else if (typeof obj == "object") { for (let i of Object.keys(obj)) { result.push({ name: i, value: normalizeObject(obj[i]) }); } } else { return obj; } return result; } console.log(JSON.stringify(normalizeObject(obj), null, 2));

这种循环方法称为递归。 这是通过调用函数本身来循环的。
