qt获取本机IP地址

//获取本地IP片地址,
QList addList = QNetworkInterface::allAddresses();

&& address != QHostAddress(QHostAddress::LocalHost))
{
//输出，转换为字符串格式
qDebug() << address.toString() << “111111”;
}
}
qDebug() << “----------------------------------”;

//获取本地所有的网络接口
QList interface = QNetworkInterface::allInterfaces();
