经过前面Protocol的分析，我们已经知道框架在处理请求和回复时都是通过封装为DubboRequest和DubboResponse来做，这篇我们就开始分析DubboRequest和DubboResponse的流程。
class DubboRequest
{

private $twoWay = true;
private $heartbeatEvent = false;
private $sn; //请求序号
private $serialization;
private $fullData; //报文（包含消息头）
private $dataLen; //数据报文长度
private $requestLen; //请求报文总长度(即消息头+消息体的长度)
//包体字段
private $dubboVersion = "2.0.0"; //dubbo 版本
private $service; //服务名称
private $version; //服务版本
private $group; //服务group
private $method; //方法名
private $timeout; //超时时间(ms)
private $types; //参数类型
private $paramNum = 0; //参数个数
private $params = array(); //调用$method时的参数
