QT检查界面是否真实

Question

I am tryng to get the mac adress using QT. Right now I am using this code:

QStringList Util::getMac(){
QStringList items;

foreach(QNetworkInterface interface, QNetworkInterface::allInterfaces())
{
   if (interface.flags().testFlag(QNetworkInterface::IsRunning))
     foreach (QNetworkAddressEntry entry, interface.addressEntries())
     {
       if (interface.hardwareAddress() != "00:00:00:00:00:00" && entry.ip().toString().contains(".")){
         items << interface.hardwareAddress();
       }
     }
}
return items;}

But the problem is that it also gives me mac adress of a hamachi interface. So is there any way to check if that interface is internet-accessible? Like that I would know that it is real and not virtual.

您可以通过http://qt-project.org/doc/qt-4.8/qnetworkinterface.html#allAddresses检查接口的IP，然后查看它是否是可以连接到Internet的地址
