1. 产品介绍对于网上商城,其最大好处是要能给用户带来最大的便捷,这种便捷不仅体现在网络之外的物流、商品的折扣等,更要体现在进行网络操作时的易用性,能够模拟用户的购物行为,营造一种尽量真实、贴切的用户购物过程。所以,在设计网络商城时,最重要的就是完成“用户功能”。其次,对众多商品、订单、用户信息的网络管理,对于网站经营者的经营效率的意义,也是不言而喻的,这些则可以称为“管理功能”。
2. 产品面向的用户群体本系统主要面向系统管理员和普通用户。

可以勾选商品进行计算价格,然后进行商品结算 去订单页面付款,也可以选择删除购物车里面的商品。
我的订单:可以查看自己的订单的商品,设置5s时间自动关闭。支付使用支付宝沙箱支付,对于已经支付的订单无法二次支付,即使支付也会报错,对于已支付的订单也不能进行取消。
返回数据:支付宝进行回调信息存储到数据库,后台可以接收信息。
进行支付之后,后台可以对订单进行发货,用户在我的订单里面也可以看见订单状态是否发货,从而进行收货操作。
