Node.js：从 JSON 响应中提取数据

Question

I'm fetching product details using an API which gives the response as a JSON object.

{
    "productBaseInfo": {
        "productIdentifier": {
            "productId": "EKTDDD23232zYHR94E4",
        },
        "productAttributes": {
            "title": "Nova KT 72BC 1 Electric Kettle",
            "imageUrls": {
                "400x400": "http://img5a.flixcart.com/image/electric-kettle/4/e/4/nova-kt-722-c-kt-722c-400x400-imadddh2fdvuzpxz.jpeg",
                "75x75": "http://img6a.flixcart.com/image/electric-kettle/4/e/4/nova-kt-722-c-kt-722c-75x75-imadddh2fdvuzpxz.jpeg",
            },
            "sellingPrice": {
                "amount": 599.0,
                "currency": "INR"
            },
            "productUrl": "http://dl.mykart.com/dl/nova-kt-722c-1-electric-kettle/p/itmdddf398rhhhz2?pid=EKTDDDEGXYHR94E4&affid=userid"
        }
    }
}

Now I want to get the productId, title in ProductAttributes, and all the image urls and productURL. I tried

var productURL = JSON["productAttributes"].productUrl 

But it returns an error productUrl not found error. Looking for suggestion on how to extract the data. Thanks in advance.

Answer 1

productAttributes is inside productBaseInfo . So you need to access it like this

console.log(JSON.productBaseInfo.productAttributes.productUrl);
