管理系统(FastAPI+Vue3) 适合python毕业设计 FastAPI源码 python课程设计 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的鲜花商城(花店)管理系统(FastAPIVue3)。项目介绍随着鲜花零售从线下门店加速转向线上渠道传统花店普遍面临商品展示能力不足、订单流转不透明、库存与销量难以及时掌握等问题。针对这一现实需求本文设计并实现了一套基于Python的鲜花商城(花店)系统。系统采用前后端分离架构后端以Python 3为开发语言使用FastAPI构建RESTful接口借助Pydantic完成请求体校验借助SQLAlchemy 2.0完成对象关系映射数据存储于MySQL 8数据库db_flower_shop前端以Vue3为核心结合Vue Router、Pinia、Element Plus与ECharts分别实现会员商城与管理员后台。身份认证采用JWT按照管理员与会员两种角色签发令牌并在中间件中完成路径级鉴权。在业务功能方面会员端覆盖注册登录、分类浏览、鲜花检索、购物车、收货地址、下单支付、确认收货、商品评价、收藏与浏览记录、公告资讯以及个人中心等完整购物闭环管理端覆盖工作台数据统计、分类与鲜花维护、会员启用禁用、订单发货、评价回复、公告发布以及个人资料与密码管理。订单处理在同一事务中完成库存扣减、明细快照与购物车清理支付成功后累计销量取消未支付订单时回补库存从而保证交易数据的一致性。后台首页以近七日订单趋势、分类销量占比和热销TOP5图表辅助经营决策。本文按照软件工程方法依次完成可行性分析、需求分析、概念结构设计、逻辑结构设计、接口设计、编码实现与功能测试。测试结果表明系统主要业务流程运行稳定接口返回结构统一日期时间显示符合YYYY-MM-DD与YYYY-MM-DD HH:MM:SS规范能够满足本科毕业设计对完整性、规范性和可演示性的要求也可作为中小型花店数字化经营的参考实现。源码下载链接: https://pan.baidu.com/s/1M7I7ngNwVTUhh3f-P4T1jw?pwd1234提取码: 1234系统展示核心代码 订单业务实现负责下单、支付、发货和收货 import random from decimal import Decimal from sqlalchemy import select from sqlalchemy.orm import Session from app.common.convert import now, order_dict from app.common.exceptions import BizException from app.models import Address, Cart, Flower, Order, OrderItem def build_order_no() - str: 生成订单号FS 时间 3位随机数 time_part now().strftime(%Y%m%d%H%M%S) return FS time_part f{random.randint(0, 999):03d} def list_items(db: Session, order_id: int): 查询订单明细 return db.scalars(select(OrderItem).where(OrderItem.order_id order_id)).all() def detail(db: Session, order_id: int, user_nicknameNone): 查询订单详情并带上明细 order db.get(Order, order_id) if order is None: raise BizException(订单不存在) return order_dict(order, itemslist_items(db, order_id), user_nicknameuser_nickname) def must_own(db: Session, user_id: int, order_id: int) - Order: 校验订单属于当前会员 order db.get(Order, order_id) if order is None or order.user_id !
