这个模型比前面的超级HelloWorld稍微简单一点。客户端预定义talk函数响应来自服务器端的消息，服务器端用application.broadcastMsg来广播客户端用户的someoneTalk。换句话说，客户端的someoneTalk实际上是触发了服务器端的application.broadcastMsg，同时再回调客户端预定义的talk函数并显示消息，便搭成了聊天室。
服务器端代码如下：
- function broadcast (msg)
- {
- //trace(msg);
- application.broadcastMsg('talk', msg);
- }
- application.onConnect = function (client)
- {
- this.acceptConnection(client);
- broadcast('__ ' + client.ip + ' 进来了 __');
- }
- application.onDisconnect = function (client)
- {
- broadcast('__ ' + client.ip + ' 出去了 __');
- }
- Client.prototype.someoneTalk = function (n, w)
- {
- broadcast(n + '(' + this.ip + ') 说道: ' + w);
- }
客户端代码如下：
- _nc = new NetConnection();
- _nc.talk = function(msg)
- {
- msg_txt.text += msg + '\n';
- };
- _nc.connect('rtmp://x/chat');
- talk_btn.onRelease = function()
- {
- _nc.call('someoneTalk', null, name_txt.text, send_txt.text);
- };
- onKeyDown = function ()
- {
- if(Key.isDown(Key.ENTER)){
- _nc.call('someoneTalk', null, name_txt.text, send_txt.text);
- }
- }
- Key.addListener(this);

ps: 也可以用SharedObject的send方法向所有订阅此so的客户端发送消息以达到聊天的效果，但她无法有效地将当前聊天者的ip地址等信息广播出去。我已经试过了，谁要有兴趣的话也不妨试一试。
