Qt获取本机IP地址：

Qt版本：4.8.6

#include <QtNetwork/QNetworkInterface.h>

    QString ipAddr;
    QList<QHostAddress> list = QNetworkInterface::allAddresses();
    foreach (QHostAddress address, list) {
        if (address.protocol() == QAbstractSocket::IPv4Protocol) {
            ipAddr = address.toString();
            break;
        }
