Qt获取本机IPV4 IP地址

挺简单的代码，直接看吧

#include #include /*************************************  * 获取本机 IPV4 地址，如果有多个，返回第* 一个有效的IPV4地址**************************************/QHostAddress getHostIPV4Address(){foreach(const QHostAddress& hostAddress,QNetworkInterface::allAddresses())if ( hostAddress != QHostAddress::LocalHost && hostAddress.toIPv4Address() )return hostAddress;return QHostAddress::LocalHost;}
