[Qt]获取Mac系统的有效网卡和序列号及硬件ID等信息（

//获取序列号
QProcess proc;
QStringList args;
args << "-c" << "ioreg -rd1 -c IOPlatformExpertDevice |  awk '/IOPlatformSerialNumber/ { print $3; }'";
proc.start( "/bin/bash", args );
proc.waitForFinished();
qDebug()<< proc.readAll(); //可以通过mid(1,11) 取得其中的序列号信息
//若是想获取硬件ID可把上面的 IOPlatformSerialNumber 改为 IOPlatformUUID 即可

//获取系统用户名，要#include <stdlib.h>
qDebug()<<getenv("USER");
//获取有效网卡，要#include <QtNetwork/QNetworkInterface>
QString  strMac;
QList<QNetworkInterface> ifaces = QNetworkInterface::allInterfaces();//获取所有网卡信息
for (int i = 0; i < ifaces.count(); i++)
{
QNetworkInterface iface = ifaces.at(i);
if ( iface.flags().testFlag(QNetworkInterface::IsUp) && iface.flags().testFlag(QNetworkInterface::IsRunning) && !iface.flags().testFlag(QNetworkInterface::IsLoopBack))
{ //获取当前有效网卡
for (int j=0; j<iface.addressEntries().count(); j++) //这个循环很重要，读者可以尝试不用这个循环看看获取的是不是当前有效网卡：）
{
/* we have an interface that is up, and has an ip address
* therefore the link is present
* we will only enable this check on first positive,
* all later results are incorrect * * */
strMac = iface.hardwareAddress();
i = ifaces.count(); //跳出外层循环
break;
}
}
}
if(strMac.isEmpty()) { //有时候还是获取不到，所以这边再次尝试获取
foreach(QNetworkInterface iface,ifaces)
{
if(!iface.flags().testFlag(QNetworkInterface::IsLoopBack)) {
strMac = iface.hardwareAddress();
break;
}
}
}
qDebug()<<strMac;
