本篇文章给大家带来的内容是关于微信小程序商城开发之动态API实现商品的详情页的代码（上） ，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
看效果
开发计划
1、实现商品详情页面布局（这篇实现3个模块，头部商品图片轮播、商品价格和商品描述、商品详情展示）
2、根据用户点击不同的商品请求API动态加载数据
根据商品ID获取商品详情API数据模型
访问：https://100boot.cn/ 选择微商城案例，如下图所示：
下方还有详细的数据模型可以查看哦！
home.js 增加跳转商品详情事件
上一篇还记得我们做了商品点击查看详情的事件采集吗？那么再加上跳转商品详情页功能，如下图所示：
