Qt编程14：Qt获取本地网络IP地址以及其他属性（以IPv4为例）

Qt网络编程：获取本地Ip地址：

 

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

    foreach(QHostAddress address,addList)
    {
        //排除IPV6，排除回环地址
        if(address.protocol() == QAbstractSocket::IPv4Protocol
                && address != QHostAddress(QHostAddress::LocalHost))
        {
            //输出，转换为字符串格式
            qDebug() << address.toString();
        }
    }
    qDebug() << "----------------------------------";

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

    foreach(QNetworkInterface inter,interface)
    {
        QList entrList = inter.addressEntries();

        foreach(QNetworkAddressEntry entr,entrList)
        {
            QHostAddress hostIp = entr.ip();
            if(hostIp.protocol() == QAbstractSocket::IPv4Protocol &&
                    hostIp != QHostAddress(QHostAddress::LocalHost))
            {
                //获取输出名称
                qDebug()<

一般结合下拉框使用
