QT 获取 本机IP地址 MAC地址

    QString str1;

    QHostInfo info = QHostInfo::fromName(QHostInfo::localHostName());

    QHostAddress address = info.addresses().first();      //第一个IP地址；

    str1 = address.toString();

    QString str2;

    QList<QNetworkInterface> list = QNetworkInterface::allInterfaces();

    str2 = list.at(1).hardwareAddress();                  //MAC地址；
