管理系统(FastAPI+Vue3) python课程设计 微信小程序课程设计，微信小程序毕业设计 锋哥原创出品，必属精品)
大家好，我是Java1234_小锋老师，分享一套锋哥原创的基于Python的微信小程序校园失物招领管理系统(FastAPI+Vue3)。
项目介绍
鲜花消费已经从节日礼品延伸到日常探望、毕业纪念和商务拜访。传统花店依赖店员记库存、手工开单，订单状态不容易同步给顾客，节假日还容易出现超卖和漏单。微信小程序适合作为会员侧入口，管理后台则需要在浏览器中完成商品、订单和经营统计。本文设计并实现微信小程序鲜花商城(花店)管理系统，形成“小程序购物、Vue3运营、FastAPI服务、MySQL存储”的完整方案。
系统使用Python语言和FastAPI框架实现统一接口。会员端采用微信小程序，完成注册登录、分类浏览、购物车、下单支付、收货地址、收藏、浏览记录、评价和个人中心。管理端采用Vue3、Vite、Element Plus、Pinia和ECharts，完成数据统计、分类与鲜花维护、会员启停、订单发货、评价回复、公告发布以及管理员个人中心。身份认证使用JWT，角色分为管理员和会员。数据库名为db_flower_shop，业务表以t_开头，界面日期统一显示为2026-11-02，日期时间统一显示为2026-11-02 17:25:17。
论文按软件工程过程组织。先分析花店业务和两种角色的需求，再给出功能结构、总体架构、实体属性图、实体联系图和关键时序图，然后列出十二张数据表的字段名、字段类型、长度、是否为空和备注，并在系统实现中给出注册登录、购物车、下单、发货和统计等核心代码。测试表明，会员可以从浏览走到确认收货，管理员可以完成日常运营和首页图表查看。系统结构清楚，适合作为本科毕业设计，也可作为中小花店的信息化原型。
