【门户】

1.购物车List列表

/cart/list.do

http://localhost:8080/cart/list.do

注意点：

需要先登录,所有的密码都是123
NEED_LOGIN(10, "NEED_LOGIN"),//需要登录的错误编码
价格的单位是元,保留小数后2位

request

无参数,需要登录状态

response

success


{
    "status": 0,
    "data": {
        "cartProductVoList": [
            {
                "id": 1,
                "userId": 13,
                "productId": 1,
                "quantity": 1,
                "productName": "iphone7",
                "productSubtitle": "双十一促销",
                "productMainImage": "mainimage.jpg",
                "productPrice": 7199.22,
                "productStatus": 1,
                "productTotalPrice": 7199.22,
                "productStock": 86,
                "productChecked": 1,
                "limitQuantity": "LIMIT_NUM_SUCCESS"
            },
            {
                "id": 2,
                "userId": 13,
                "productId": 2,
