Qt下如何获得本地网卡IP

#include <QtDebug>#include <QHostAddress>#include <QNetworkInterface>#include <QTextCodec>GetIpv4::GetIpv4(){    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));    QList<QHostAddress> vAddressList = QNetworkInterface::allAddresses();    for(int i=0;i<vAddressList.size();i++)    {        qDebug()<<vAddressList.at(i);        if((vAddressList.at(i)!=QHostAddress::LocalHost)&&(vAddressList.at(i).protocol()==QAbstractSocket::IPv4Protocol))            qDebug()<<QString("本机IP地址是：")<<vAddressList.at(i).toString();    }}

以上是代码：

以下是运行结果：

 

 QHostAddress( "127.0.0.1" ) 
 QHostAddress( "0:0:0:0:0:0:0:1" ) 
 QHostAddress( "192.168.0.105" ) 
"本机IP地址是：" "192.168.0.105"
 QHostAddress( "FE80:0:0:0:20C:29FF:FE1B:6F25" )
