TP5.1.18+swoole实现聊天室

---

TP是最新版本的;
大概实现的有,用户注册,注册完毕以后跳转到登陆页面;
登陆以后生成身份令牌(token)存到Redis;
在聊天界面没有任何ajax请求,只要在握手的时候有一个http请求,实在是搞不懂一些人,在聊天界面发布消息用ajax去发布,

作了一些处理,一个浏览器里面只能用一个帐号,因此测试的时候必须用两个浏览器

以后跳转到聊天界面,而后创建WebSocket握手,在握手的同时携带toekn,以及对方的ID(朋友的ID) ;

后台服务器在OnOpen的时候作一系列的操做,例如(检测token,检测朋友的ID,将本身的ID和fd更新到数据表,fd绑定uid等..);
这些检测都经过以后获取聊天记录,为了效率是拉取和朋友的15条聊天记录;

在OnMessage中获取了发送的数据!
在发送以后检测对方是否在线,若是不在线就不用发送给对方,若是对方在线就将信息push给他!

心跳检测: 每5秒检测一次,若是在100秒没有任何操做将断开链接,断开链接的同时将数据库中的fd清空!

代码很简单,,,可是有个别的问题没有解决,好比在线统计(connections)

下面贴上Socket_Server.php的代码 其余的都是没有什么逻辑的代码!

完整的等以后写完了再发出来吧,你们共同进步!
