QT获取网络接口信息包括主机名、物理地址等

1.界面ui

2.添加头文件

3.添加函数声明

4.添加.cpp代码

5.运行

1.界面ui

2.添加头文件

NetInfoDialog.h

复制代码

#include <QDialog>
#include <QHostInfo>
#include <QNetworkInterface>
#include <QHostAddress>
#include <QMessageBox>

3.添加函数声明

private slots:
    void on_pushButton_clicked();
public:
    //获取当前的主机名和IP地址
    //对应当前系统"/etc/hosts"文件
    void getHostInfo();

4.添加.cpp代码

复制代码

NetInfoDialog::NetInfoDialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::NetInfoDialog)
{
    ui->setupUi(this);
    getHostInfo();
}

NetInfoDialog::~NetInfoDialog()
{
    delete ui;
}

void NetInfoDialog::on_pushButton_clicked()
{
    //创建保存详细地址信息的字符串
    QString detail;
    //获取所有的网络接口
    QList<QNetworkInterface> list =
            QNetworkInterface::allInterfaces();
    for(int i = 0 ;i<list.count(); i++){
        QNetworkInterface interface = list.at(i);
        //设备名
        detail += "设备：" + interface.name() + "n";
        //MAC
        detail += "硬件地址:" +
                interface.hardwareAddress() + "n";
        //IP、子网、广播
        QList<QNetworkAddressEntry> entrylist =
                        interface.addressEntries();
        for(int j=0; j<entrylist.count()-1; j++){
            QNetworkAddressEntry entry =
                                entrylist.at(j);
            detail += "IP地址：" +
                    entry.ip().toString() + "n";
            detail += "子网掩码：" +
                    entry.netmask().toString() + "n";
            detail += "广播地址：" +
                    entry.broadcast().toString() +"n";
        }
    }
    //显示到提示框
    QMessageBox::information(this,"详细网络信息",
                             detail);
}

void NetInfoDialog::getHostInfo()
{
    //获取主机名
    QString hostName = QHostInfo::localHostName();
    //显示主机名到UI
    ui->hostnameEdit->setText(hostName);
    //通过主机名获取对应的地址
    QHostInfo info = QHostInfo::fromName(hostName);
    if(!info.addresses().isEmpty()){
        //获取IPV4地址
        QHostAddress addr = info.addresses().first();
        //显示地址
        ui->ipAddrEdit->setText(addr.toString());
    }
}
