有了WebSocket的经验，这次写Socket.IO的Client顺利了很多，参考之前的文章：socket接口开发和测试初探、IntelliJ中基于文本的HTTP客户端、基于WebSocket的client封装。之前的代码有更新，主要修复了一些BUG以及增加了一些功能方便在实际功能测试中使用，关于性能测试的，接下来还会在继续优化和多线程Socket接口的测试实践。
本次与WebSocket区别在于多记录了一些监听event的名称，不知道会有啥用，我猜将来用于做收到消息的响应业务的话，应该会用到，所以用看了一个public ConcurrentSet<String> events = new ConcurrentSet<>();记录。
关于send()方法，我并没有进行多个重载，测试代码中大家可以看到，我直接用的String类型的请求参数，然后转成JSON，打算后期直接把各种消息封装成不同的对象，所以只保留了一个send()方法。
/**
* 发送消息,暂不重载
*
* @param event
* @param objects
*/
public void send(String event, Object... objects) {
events.add(event);
this.socket.emit(event, objects);
}
