Qt5网络编程之获取本机IP地址和主机名

#include "myip.h" #include "ui_myip.h" MyIP::MyIP(QWidget *parent) : QWidget(parent), ui(new Ui::MyIP) { ui->setupUi(this); QString localhostName = QHostInfo::localHostName(); ui->IpLabel->setText(tr("主机名为：")+localhostName); localhostName = "www.baidu.com"; QHostInfo info = QHostInfo::fromName(localhostName); foreach(QHostAddress address,info.addresses()) { if(address.protocol() == QAbstractSocket::IPv4Protocol) qDebug() << address.toString(); } } MyIP::~MyIP() { delete ui; }
