\r\n
一、功能简介\r\n
1、用户随意输入一个昵称即可登录\r\n
2、登录成功后\r\n
1) 对正在登录用户来说，罗列所有在线用户列表，罗列最近的历史聊天记录\r\n
2) 对已登录的用户来说，通知有新用户进入房间，更新在线用户列表\r\n
3、退出登录\r\n
1) 目前未支持直接退出，只能通过关闭网页来退出...\r\n
2) 当有用户退出，其他所有在线用户会收到信息，通知又用户退出房间，同时更新在线用户列表\r\n
4、聊天\r\n
1) 聊天就是广播，把信息广播给所有连接在线的用户\r\n
5、一些出错处理\r\n
1) 暂时简单处理了系统逻辑错误、网络出错等特殊情况的出错提示\r\n
\r\n
二、技术简介\r\n
1、node方面主要是基于node-websocket-server这个框架；服务器和客户端用JSON数据来通讯；\r\n
2、其他的就不多说了，直接贴上这个小demo的源码地址： https://github.com/auzll/nodechat 。有兴趣的可以看看，欢迎各位网友批评指正。\r\n
\r\n
三、参考文章\r\n
1、websocket与node.js的完美结合( http://cnodejs.org/blog/?p=273 ) 。从这里了解到node-websocket-server 这个框架的，一个node.js和websocket通讯的框架，本程序中有使用到。\r\n
2、nodejs: 真正的一份代码，到处运行( http://cnodejs.org/blog/?p=702 ) 。从这里了解到如何在svr和client中同时复用部分代码，当然，本程序也模仿了这里面的技术来做，例如我源码里面svr/chatLib.js其实是同时被svr和client公用的。\r\n
\r\n
四、附带几张效果图\r\n
1、进入源码目录，svr/Main.js，执行node Main.js来启动\r\n
$\"\"$ \r\n
2、输入昵称\r\n
$\"\"$ \r\n
3、聊天主界面\r\n
$\"\"$ \r\n
4、聊天主界面之“后登陆用户查看历史消息”\r\n
