注：main_desktop.py中QQ和QQ授权码需要换成自己的！！！！！！

一、效果图

主页面 

管理员界面

读者界面

功能介绍：

1、登录

会判断账号是否存在和输入是否正确，密码错误可以进行忘记密码操作。

2、注册

会判断账号是否存在，账号、密码格式是否正确，会向所填邮箱发送验证码，并将注册后的账号密码等信息记录起来。

二、管理员系统

功能介绍：

1.书籍录入

判断书籍有没有存在，存在表现为书籍数量的增加，不存在为种类和数量的增加，记录操作者和操作时间。      

2.书籍查询

可以按编号、书籍名、作者进行模糊查询

3.书籍删除  

删除对应书籍的全部信息，记录操作者和操作时间

4.书籍修改

修改书籍数据，记录操作者和操作时间

5.借阅登记

记录借阅者和借阅数据

6.归还登记

记录归还者和归还记录

7.读者信息

可以改变读者的密码等操作
