在我们讲完了最基础的四个tabBar栏之后，商城也算是初现模样，本篇文章将会介绍商品详情页面的制作，包括把商品加入购物车的功能、分享商品信息的功能等等
效果图如下：
首先是做了是个三图轮播的样式来展示该商品，然后是商品信息的介绍，接着是分享商品和商品类型的挑选，最后使用Vant Weapp中的GoodsAction 商品导航组件来返回首页和加入购物车等操作。
具体的代码如下：
<template>
<view class="container">

</style>在商品详情页面，我目前只是添加了将商品添加到购物车的操作，首先拿到本商品的具体信息，包括商品id，名称，价格等，将该数据信息储存到本地缓存，其实需要在main.json文件中引入Vuex，然后创建Vuex.Store，把数据保存到store上，然后购物车从store中获取缓存的商品数据，完成商品加入购物车的操作。
本篇文章就先写到这里，如有不足，还望斧正，谢谢~
