如题,当游客浏览的时候那些购物车里面的数据存到哪的?

不用说一定是session。
虽然session也不一定是完全的安全,但是cookie却是完全的不安全性。
以下就是京东存在cookie的session_id了,删除了购物车就空了。
其实,如果深究这个地方还有很多细节,足够开篇文章了。
京东的购物车如何存的,游客的购物车存在哪里的?

肯定是cookie啊

session也有可能

我感觉SESSION的可能性更大点,因为我们也是用SESSION的

缓存服务器。

游客的数据应该是放在缓存服务器吧。
用redis之类的来做,如果有登录或者退出也方便操作。

刚简单的验证了一下,京东的游客购物车是加密后存入coocie的。
个人觉得可以用拼接字符串再拆解字符串的方式做购物车 split();

数据库吧,换台电脑怎么办。
