随着互联网技术的不断发展，电子商务已成为人们常用的消费方式之一。但是，目前市场上的水果销售系统还存在一些不足之处，如商品信息不够完善、用户体验不够优质等问题。本研究旨在通过基于Django框架的智能水果销售系统设计，改善传统水果销售系统的不足之处，提高用户体验和销售效率。
本系统的前台页面面向用户，通过页面设计和交互体验的优化，使得用户可以更加方便快捷地查看商品信息、下单购买和支付等操作。同时，加入了智能推荐功能，根据用户的浏览记录、购买历史和兴趣偏好等信息，为用户推荐最符合其需求的商品，提高用户购物体验。本系统的后台管理部分则面向商家，提供了一套完善的商品管理、订单管理系统。商家可以通过后台管理系统对商品信息进行添加、编辑和上下架等操作，同时可以查看订单信息和用户反馈等数据，以便更好地优化产品和服务。本设计使用了Django框架 实现了智能水果销售系统。Django框架的基本特性和优势，然后详细设计了智能水果销售系统的整体架构和关键功能模块。在此基础上，使用Python语言进行系统的实现，并通过黑盒测试、白盒测试等多种方式进行了系统测试。本次研究的系统使用了DJANGO框架、VUE框架等技术，还有 MySQL数据库，最终实现了智能水果销售的系统设计。
本系统主要包括：用户管理模块，个人中心，水果类别管理模块，用户下单，用户信息，水果信息模块等。随着智能水果销售的系统的正式启用，水果的购买率得到了提高，给老百姓的出行带来了巨大的方便，更是促进了共享经济社会的良好发展。
