node和vue實現商城用戶地址模塊的實現

server/models/user.js

var mongoose = require('mongoose')
var userSchema = mongoose.Schema({
    "userId":String,   // 用戶Id
    "userName":String, // 用戶名
    "userPwd":String,  // 用戶密碼
    "orderList":Array,  // 訂單列表
    "cartList":[ // 購物車列表
        {
            "productId": String,  // 商品Id
            "productName": String, // 商品名稱
            "salePrice":String, // 商品價格
            "productImage":String, // 圖片地址
            "checked":String, // 是否選中
            "productNum":String // 商品數量
        }
    ],
    "addressList":[ // 用戶地址列表
      {
        "addressId": String,
        "userName": String,
        "streetName": String,
        "postCode": Number,
        "tel": Number,
        "isDefault": Boolean
      }
    ]
});

// 通過module.exports進行輸出，這樣才能加載到  三個參數分別是 模型名,userSchema名,管理數據庫集合名
module.exports = mongoose.model("User",userSchema,"users");
