                                                            server

2. 报文格式

  • 注册报文
+------------+----+-------+----+
|request type|name|ip addr|port|
+------------+----+-------+----+
  • 转发报文
+------------+--------+--------+-------+
|request type|src name|dst name|content|
+------------+--------+--------+-------+
  • 操作报文
+------------+--------+--------+
|request type|src name|dst name|
+------------+--------+--------+

3. 客户端指令

  • REGISTER 注册用户
  • REFLECT 消息回射
  • TRANSFER 消息转发
  • BROADCAST 消息广播
  • GETALLUSER 获取所有用户名
  • LOGOUT 登出
  • ADMIN 升级为管理员
  • KICKOUT 剔除用户
  • BANTALK 禁言
  • SHUTDOWN 关闭服务器

4. 总结

不想再造轮子了=_=
1. 多个线程读取一个不存在写操作的共享资源不必加锁,存在写操作必须加锁
2. 聊天服务器可以扩展为多进程或者多机器之间的交互程序
