二、项目功能介绍

功能介绍：

本系统使用php、uni-app框架、MySQL数据库技术开发的四大名著儿童阅读app，系统分为前台和后台，用户和管理员两种用户角色，不同的用户角色有不同的功能模块，管理员可以根据系统给定的账号进行登录，登录后可以进入四大名著儿童阅读app，对后台所有模块进行管理。包括查看和修改自己的个人信息以及登录密码。该系统为每一个用户都分配了一个用户账号，用户通过账号的登录可以在系统中查看app内容及对个人信息进行修改等功能。

前台用户端：App的登录与注册，首页，图书信息，留言反馈，学习园地，个人中心等功能模块；

后台管理员端：管理员登录，首页，个人中心，用户管理，故事人物管理、图书信息管理，学习园地，系统管理等功能模块。
