Vue2.0+Node.js+MongoDB全栈打造商城系统（第11章）

第11章 购物车模块实现

11-1 购物车列表功能实现

注意：

  • 组件名NavHeader 标签用写成<nav-header>
  • @keyup.enter="login" 按回车登录

新增ImoocMall/src/views/Cart.vue：

<template>
  <div>
    <nav-header></nav-header>
    <nav-bread>
      <span>My Cart</span>
    </nav-bread>

        });
      }
    }
  }
</script>

ImoocMall/src/router/index.js中新增 cart 路由：

import Vue from 'vue'
import Router from 'vue-router'
import GoodsList from './../views/GoodsList'
import Cart from './../views/Cart.vue'

Vue.use(Router)
export default new Router({
  routes: [
    {
      path: '/',
      component:GoodsList
    },
    {
      path: '/cart',
      name:'Cart',
      component:Cart
    }
  ]
})

服务端ImoocMall/server/routes/users.js新增查询购物车列表接口：

//查询当前用户名下的购物车数据
router.get("/cartList",function (req, res, next) {
  var userId = req.cookies.userId;

  User.findOne({userId:userId},function (err,doc) {
    if (err) {
      res.json({
        status: '1',
        msg: err.msg,
        result: ''
      });
    }else {
      res.json({
        status: '0',
        msg:'',
        result: doc.cartList
      });
    }
  })
})

11-2 商品删除功能实现

注意:

  • node:代理配置里面
      • 代表当前目录下的子目录;

    • ** 代表所有子孙级目录;

        proxyTable: {
    '/goods': {
      target: 'http://localhost:3000'
    },
    '/goods/*':{
      target:'http://localhost:3000'
    },
    '/users/**':{
      target:'http://localhost:3000'
    }
  },
  • mongoose通过update删除$pull
  • 在组件里面定义的属性和自定义事件叫mdshow和close，父组件在使用的时候必须使用这个名字

ImoocMall/server/routes/users.js新增删除商品接口:

//购物车商品删除
router.post("/cartDel", function (req,res,next) {
  var userId = req.cookies.userId,productId = req.body.productId;
  User.update({
    userId:userId
  },{
    $pull:{
      'cartList':{
        'productId':productId
      }
    }
  }, function (err,doc) {
    if(err){
      res.json({
        status:'1',
        msg:err.message,
        result:''
      });
    }else{
      res.json({
        status:'0',
        msg:'',
        result:'suc'
      });
    }
  });
});
