数据管理模块（数据库设计）

数据库中有可能存在很多张表，每张表中管理的数据⼜有不同，要进⾏的数据操作也各不相同，因此我们可以为每⼀张表中的数据操作都设计⼀个类，通过类实例化的对象来访问这张数据库表中的数据，这样的话当我们要访问哪张表的时候，使⽤哪个类实例化的对象即可。
创建user_table类，该类的作⽤是负责通过 MySQL 接⼝管理用户数据。主要提供了四个⽅法：

• select_by_name:根据用户名查找用户信息，用于实现登录功能
• insert:新增用户，用户实现注册功能
• login:登录验证，并获取完整的用户信息
• win:⽤于给获胜玩家修改分数
• lose:用户给失败玩家修改分数

业务处理模块

服务器模块，是对当前所实现的所有模块的⼀个整合，并进⾏服务器搭建的⼀个模块，最终封装实现出⼀个gobang_server的服务器模块类，向外提供搭建五⼦棋对战服务器的接口。通过实例化的对象可以简便的完成服务器的搭建。

通信接口设计（Restful⻛格）

静态资源请求：

静态资源⻚⾯，在后台服务器上就是个html/css/js⽂件静态资源请求的处理，其实就是将⽂件中的内容发送给客⼾端
1. 注册⻚⾯请求

会话管理模块网络通信模块（session,cookie)

session类设计实现
• 这⾥我们简单的设计⼀个session类，但是session对象不能⼀直存在，这样是⼀种资源泄漏，因此需要使⽤定时器对每个创建的session对象进⾏定时销毁（⼀个客户端连接断开后，⼀段时间内都没有重新连接则销毁session）。
• _ssid使⽤时间戳填充。实际上，我们通常使⽤唯⼀id⽣成器⽣成⼀个唯⼀的id
• _user保存当前用户的信息
• timer_ptr_tp保存当前session对应的定时销毁任务

typedef enum {UNLOGIN, LOGIN} ss_statu;
class session {private:uint64_t _ssid;//标识符uint64_t _uid;//session对应的⽤⼾IDss_statu _statu;//⽤⼾状态：未登录，已登录wsserver_t::timer_ptr _tp;//session关联的定时器public:session(uint64_t ssid): _ssid(ssid){ DLOG("SESSION %p 被创建！！", this); }~session() { DLOG("SESSION %p 被释放！！", this); }uint64_t ssid() { return _ssid; }void set_statu(ss_statu statu) { _statu = statu; }void set_user(uint64_t uid) { _uid = uid; }uint64_t get_user() { return _uid; }bool is_login() { return (_statu == LOGIN); }void set_timer(const wsserver_t::timer_ptr &tp) { _tp = tp;}wsserver_t::timer_ptr& get_timer() { return _tp; }
};

session管理设计实现
session的管理主要包含以下⼏个点：
1. 创建⼀个新的session
2. 通过ssid获取session
3. 通过ssid判断session是否存在
4. 销毁session
5. 为session设置过期时间，过期后session被销毁

在线管理模块

在线用户管理，是对于当前游戏⼤厅和游戏房间中的用户进⾏管理，主要是建⽴起用户与Socket连接的映射关系，这个模块具有两个功能：
1. 能够让程序中根据用户信息，进⽽找到能够与用户客户端进⾏通信的Socket连接，进⽽实现与客户端的通信。
2. 判断⼀个用户是否在线，或者判断用户是否已经掉线

class online_manager {private:/*游戏⼤厅的客⼾端连接管理*/std::unordered_map<uint64_t, websocket_server::connection_ptr>

房间管理模块

房间类实现
⾸先，需要设计⼀个房间类，能够实现房间的实例化，房间类主要是对匹配成对的玩家建⽴⼀个小范围的关联关系，⼀个房间中任意⼀个用户发⽣的任何动作，都会被⼴播给房间中的其他用户。
⽽房间中的动作主要包含两类：
1. 棋局对战
2. 实时聊天

用户匹配模块

匹配队列实现
五子棋对战的玩家匹配是根据自己的天梯分数进⾏匹配的，而服务器中将玩家天梯分数分为三个档次：
1. 青铜：天梯分数小于2000分
2. 白银：天梯分数介于2000~3000分之间
3. 黄金：天梯分数⼤于3000分
⽽实现玩家匹配的思想⾮常简单，为不同的档次设计的各自匹配队列，当⼀个队列中的玩家数量⼤于等于2的时候，则意味着同⼀档次中，有2个及以上的⼈要进⾏实战匹配，则出队队列中的前两个用户，相当于队⾸2个玩家匹配成功，这时候为其创建房间，并将两个用户信息加⼊房间中。
