获取有效的MAC地址

QString getValidMacAddr(){    foreach(QNetworkInterface networkInferface, QNetworkInterface::allInterfaces())    {        //get current valid network card        if ( networkInferface.flags().testFlag(QNetworkInterface::IsUp)            && networkInferface.flags().testFlag(QNetworkInterface::IsRunning)            && !networkInferface.flags().testFlag(QNetworkInterface::IsLoopBack))        {            //There may be a virtual network card, but we only take the first valid card            return networkInferface.hardwareAddress();        }    }}
