1、项目介绍及开发技术

1.1 项目介绍

在快节奏的现代生活中，人们越来越重视饮食健康和美食体验。然而，面对琳琅满目的食材和多样的烹饪方法，许多人在选择和制作美食时感到困惑。为了帮助用户更好地发现和学习美食，我们基于Python开发了豆果美食推荐系统。

背景： 传统的菜谱书籍和杂志虽然提供了丰富的美食信息，但往往缺乏互动性和实时更新。随着互联网技术的发展，用户更倾向于通过在线平台获取美食灵感和学习烹饪技巧。此外，个性化的美食推荐和社区交流也成为了用户的需求。

目的意义：

个性化推荐： 系统通过分析用户的口味偏好和烹饪习惯，提供个性化的美食推荐。
丰富的美食信息： 用户可以浏览各种菜品信息、配料信息和美食资讯，满足不同用户的需求。
便捷的交流平台： 留言板功能允许用户分享烹饪经验、交流美食心得，增强用户间的互动。
提升烹饪技能： 通过学习平台上的菜谱和美食信息，用户可以提高自己的烹饪技能。
支持决策制定： 系统为管理员提供了用户管理和内容管理工具，帮助优化内容策略和提升用户体验。

综上所述，豆果美食推荐系统旨在为用户提供一个全面、互动的美食信息平台，通过技术手段优化美食推荐流程，提升用户的烹饪体验和美食享受。

1.2 开发技术

技术仅供参考，普通Python Web项目，一般采用Django/Flask(少用)+Vue+MySQL，爬虫框架为Scrapy。Python大数据项目，一般采用了Hadoop、Spark、Scrapy、DataGrip等。

这个结构图展示了前后端的功能模块。前台主要面向用户，提供登录、注册、浏览首页、查看菜品信息、配料信息、美食信息、美食资讯以及留言板和个人中心等功能。

后台则为管理员提供了系统管理的界面，包括用户管理、菜谱分类管理、菜谱信息管理、配料信息管理、美食信息管理和留言板管理等。管理员可以通过这些模块对系统内的数据进行维护和管理，确保系统的稳定运行和信息的准确性。通过这样的系统设计，豆果美食推荐系统能够为用户提供便捷的美食信息和推荐服务，同时为系统管理者提供高效的管理工具。
