交作业啦 

前端：html+css+js+Vue+Element-ui

后端：Django+DRF+celery+haystack+django_crontab

数据库：Mysql+Redis

一些技术和功能：

• 为session、短信验证码、用户浏览记录、购物车、异步任务队列 创建缓存
• whoosh搜索引擎
• 异步任务队列 用于发送邮件、短信
• 定时任务 定时更新静态页面、刷新日志等
• 腾讯云短信服务
• chatGPT客服(New)
• 支付宝沙盒
• 客服群聊
• 数据库乐观锁
• 页面静态化
• JWT认证
• 发货地址、不同的商品的详情、售后服务等都可以通过后台设置
• 自选CPU、内存、显卡
• "点击此处确认验证邮箱"
• 对于未登录的用户，购物车数据使用浏览器cookie保存 登陆后合并购物车 对于已登录的用户，购物车数据在后端使用Redis保存

效果如下：

代码过多，这里只展示一部分，欢迎感兴趣的小伙伴一起讨论学习：
