【免费】基于Python的微信小程序网约车(打车，在线叫车，移动出行)系统(FastAPI+Vue3) 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的微信小程序网约车(打车，在线叫车，移动出行)系统(FastAPI+Vue3) 。

项目介绍

随着移动互联网与共享经济的深入发展，网约车已成为城市出行的重要方式。传统打车模式存在供需匹配效率低、信息不对称、服务质量难监管等问题，而基于微信小程序的轻量级应用能够降低用户使用门槛，便于快速触达乘客与司机两端。本文围绕"微信小程序网约车系统"这一课题，采用前后端分离架构，设计并实现了一套覆盖乘客出行、司机接单与后台运营管理的完整业务系统。

系统后端基于Python语言与FastAPI框架构建RESTful接口服务，结合SQLAlchemy完成对象关系映射，使用MySQL数据库持久化业务数据；管理端采用Vue3、Vite、Element Plus与ECharts实现可视化运营后台；乘客端与司机端分别开发微信小程序，通过用户名密码完成注册登录，并支持个人资料、头像与密码修改。系统实现了叫车下单、价格预估、司机抢单、行程状态流转、余额支付、评价投诉、公告发布、司机审核及数据统计等核心功能，并利用WebSocket实现订单状态的实时推送，提升了调度响应效率。

数据库设计以db_taxi为库名，表名统一以t_开头，围绕乘客、司机、车辆、车型、订单、评价、投诉、公告、余额流水与司机位置等实体展开。论文给出了实体属性图、实体关系图、系统功能结构图与关键业务时序图，详细描述了各数据表字段结构，并结合核心代码说明了主要功能的实现过程。测试结果表明，系统功能完整、流程闭环，能够满足本科毕业设计对工程实践与文档规范的要求，也为同类出行类应用的二次开发提供了可复用的技术路径。
