feat: 多班级版班级管理系统 v2.0
技术栈:Go (Gin + GORM) + PHP + MySQL 5.7 + Redis 主要功能: - 多班级完全隔离(class_id 贯穿全系统) - 后端 Go Gin(端口 56789),Nginx 反代 - 超级管理员独立登录(env 配置,默认账密 admin/Admin123) - bcrypt 密码加密(无 PASSWORD_SALT) - 科任老师/课代表新角色 - 课代表作业管理页面 - 排行榜分项排行(操行分/考勤/作业) - 角色加减分上下限由班主任配置 - 家长改密功能(可开关) - 班级角色按需开关 - 宿舍号格式:南0-000 - 周度/月度重置功能 - MySQL 5.7 兼容 - 43 轮代码审查 + 全部修复 开发者: Canglan 版权归属: Sea Network Technology Studio 许可证: Apache License 2.0
