实例中用到了(实例在Windows XP下运行)：、、、、

 

先在hosts文件中添加两行规则，关于两个子域的：sub1.localhost、sub2.localhost

使用socket.io

1: var exp = require('express');

2: var app = exp.createServer();

3: 

4: global.socket = require('socket.io').listen(app);

5: global.socket.set('log level', 1);

6: global.socket.set('transports', [ 'websocket', 'flashsocket', 'htmlfile', 'xhr-polling', 'jsonp-polling']);

加载配置，创建子域的应用

1: app.use(exp.vhost('sub1.' + global.host, require('./subdomains/sub1')));

2: app.use(exp.vhost('sub2.' + global.host, require('./subdomains/sub2')));

3: 

4: require('./app/config')(app, exp);

5: require('./app/server/router')(app);

6: require('./app/server/modules/chat-socket');

chat-socket.js模块

1: module.exports = function() {

2:

3:     global.socket.of('/chat').on('connection', function(socket) {

4:        //todo

5:     });

6: }();

前台页面使用socket.io.js建立连接

1: socket = io.connect('/chat');

2: socket.on('status', function (connections) {

3:

4: });

5: socket.on('user-ready', function (data) {

6:

7: });

8: socket.on('user-message', function (data) {

9:

10: });

11: 

12: socket.on('user-disconnected', function (data) {

13:

14: });

15: 

16: //向后台发送消息

17: socket.emit('user-ready', {name : 'xxx'});

 

运行完整的示例node app.js即可，
