            EventCenter.AddListener<NetProtoType, IOCPServerSession, byte[]>(NetProtoType.IOCPReceive, IOCPMsgReceive);
            EventCenter.AddListener<MsgId, HttpListenerResponse, MsgData>(MsgId.Regist, RegistEventDispose);
        RemoveListener:
            EventCenter.RemoveListener<NetProtoType, IOCPServerSession, byte[]>(NetProtoType.IOCPReceive, IOCPMsgReceive);
            EventCenter.RemoveListener<MsgId, HttpListenerResponse, MsgData>(MsgId.Regist, RegistEventDispose);
        BroadCast:
            EventCenter.BroadCast((MsgId)msgData.msgId, session, msgData);
            EventCenter.BroadCast(NetProtoType.HTTPPostReceive, response, content);
