新 API 功能示例：

你可以指定一个函数来检测 origins，代替之前的 string representation (though the string representation still works as usual)：

var sockets = io({
origins: function (origin, fn) {
if (origin == 'http://foo.example') {
return fn(null, true);
}
return fn(null, false);
}
});

初始化客户端的时候，不需要协议也能运行相关 urls ：

var socket = io('//localhost:3000');

你可以手动管理重新连接：

var socket = io({ forceNew: true });

socket.once('connect', function() {
socket.disconnect();
});

socket.once('disconnect', function() {
socket.once('connect', function() {
console.log('Connected for the second time!');
});
socket.connect();
});

跟往常一样，你可以通过 CDN 获取新客户端：

<script src="https://cdn.socket.io/socket.io-1.2.0.js"></script>

Socket.IO 实现了实时双向的基于事件的通讯机制。旨在让各种浏览器与移动设备上实现实时app功能，模糊化各种传输机制。

Socket.IO 是跨平台，多种连接方式自动切换，做即时通讯方面的开发很方便，而且能和expressjs提供的传统请求方式很好的结合，即可以 在同一个域名，同一个端口提供两种连接方式：request/response, websocket(flashsocket,ajax…).
