这个硬件信息的获取需要使用到 network 模块

# 1. 在pro文件中添加 QT += network
# 需要用到的头文件#include  // 计算机名#include   // 用户名(获取家目录，删除其它字段只保留用户名)#include   // 网卡信息

    cout << "当前计算机名:" << QHostInfo::localHostName();    cout << "当前登陆用户:" << QStandardPaths::writableLocation(QStandardPaths::HomeLocation).section("/", -1, -1);
    QList AddressList = QNetworkInterface::allAddresses();    foreach(QHostAddress address, AddressList){        if(address.protocol() == QAbstractSocket::IPv4Protocol &&                address != QHostAddress::Null &&                address != QHostAddress::LocalHost){            if (address.toString().contains("127.0.")){                continue;            }            cout << "当前IP地址：" << address.toString();            break;        }    }
    // ---> 依次输出系统中每张网卡的详细信息    QString detail="";    QList list=QNetworkInterface::allInterfaces();    for(int i=0;i<list.count();i++)< span=""></list.count();i++)<>    {        QNetworkInterface interface=list.at(i);        detail=detail+tr("设备：")+interface.name()+"n";        detail=detail+tr("硬件地址：")+interface.hardwareAddress()+"n";        QList entryList=interface.addressEntries();        for(int j=0;j<entrylist.count();j++)< span=""></entrylist.count();j++)<>        {            QNetworkAddressEntry entry=entryList.at(j);            detail=detail+"t"+tr("IP 地址：")+entry.ip().toString()+"n";            detail=detail+"t"+tr("子网掩码：")+entry.netmask().toString()+"n";            detail=detail+"t"+tr("广播地址：")+entry.broadcast().toString()+"n";        }    }    QMessageBox::information(this,tr("Detail"),detail);
