 2、响应demo:

{
    "code": 1,
    "data": {
        "skuList": [
            {
                "quantity": 2,
                "salePrice": 28.99,
                "discountPrice": 28.99,
                "skuId": "529874918398763056"
            },
            {
                "quantity": 2,
                "salePrice": 28.99,
                "discountPrice": 28.99,
                "skuId": "529874918398763050"
            }
        ]
    },
    "message": "success"
}
