微信公众平台 网站开发推广恶意点击软件怎样使用

1：用户登录系统

• 用户角色区分（管理员/普通用户）

• 注册登录流程

• 基于角色的访问控制

• 用户数据加密存储（示例未加密，实际应加密）

• 2：借阅管理系统

• 完整的借阅/归还流程

• 借阅记录管理

• 库存自动更新

• 借阅期限管理

• 借阅记录查询

• 3：数据统计功能

• 图书总量统计

• 库存总量统计

• 最受欢迎图书分析

• 借阅趋势分析（需扩展时间处理）

• 用户借阅排行（需扩展用户系统）

3：使用说明：

• 首次使用需注册管理员账号（直接修改数据文件添加admin角色用户）

• 普通用户可进行图书查询和借阅操作

• 管理员具有完整系统管理权限

• 所有数据自动保存，记录包括：

• books.txt（图书数据）

• users.txt（用户数据）

• records.txt（借阅记录）

4：扩展建议：

• 增加密码加密存储（使用加密算法）

• 完善日期处理（使用标准日期库）

• 添加借阅逾期罚款功能

• 实现图形界面（建议使用Qt框架）

• 增加图书分类和高级搜索功能

• 完善异常处理和数据验证

5：注意事项：

• 保持数据文件格式一致性

• 重要操作需要添加确认提示

• 敏感操作需要记录操作日志

• 定期进行数据备份

• 加强输入验证防止注入攻击
