QT 获取本地IP MAC地址 外网IP　位置信息 连网状态 操作系统信息

本帖最后由 Qter 于 2018-4-11 09:39 编辑

在pro文件加了一行
QT += network#include <QHostAddress>
#include <QNetworkInterface>
QString MainWindow::gethostIp()
{
    QString strIpAddress;
    QList<QHostAddress> ipAddressesList = QNetworkInterface::allAddresses();
    // 获取第一个本主机的IPv4地址
    int nListSize = ipAddressesList.size();
    for (int i = 0; i < nListSize; ++i)
    {
       if (ipAddressesList.at(i) != QHostAddress::LocalHost &&
         ipAddressesList.at(i).toIPv4Address())
       {
         strIpAddress = ipAddressesList.at(i).toString();
         break;
       }
   }
   // 如果没有找到，则以本地IP地址为IP
   if (strIpAddress.isEmpty())
      strIpAddress = QHostAddress(QHostAddress::LocalHost).toString();
   return strIpAddress;
}

QString MainWindow::gethostMac()
{
    QList<QNetworkInterface> nets = QNetworkInterface::allInterfaces();// 获取所有网络接口列表
    int nCnt = nets.count();
    QString strMacAddr = "";
    for(int i = 0; i < nCnt; i ++)
    {
      // 如果此网络接口被激活并且正在运行并且不是回环地址，则就是我们需要找的Mac地址
      if(nets.flags().testFlag(QNetworkInterface::IsUp) && nets.flags().testFlag(QNetworkInterface::IsRunning)
                && !nets.flags().testFlag(QNetworkInterface::IsLoopBack))
      {
            strMacAddr = nets.hardwareAddress();
            break;
      }
    }
    return strMacAddr;
}连网状态bool MainWindow::IPLive(QString ip, int port)
{
    QTcpSocket tcpClient;
    tcpClient.abort();
    tcpClient.connectToHost(ip, port);
    //100毫秒没有连接上则判断不在线
    return tcpClient.waitForConnected(100);
}
调用判断百度 80端口是否连通
qDebug() << IPLive("202.108.22.5", 80);外网IP及位置信息　通过网页　http://whois.pconline.com.cn/ 查询解析#include <QNetworkAccessManager>
#include <QNetworkRequest>
#include <QNetworkReply>
#include <QTextCodec>

QByteArray MainWindow::GetHtml(QString url)
{
    QNetworkAccessManager *manager = new QNetworkAccessManager();
    QNetworkReply *reply = manager->get(QNetworkRequest(QUrl(url)));
    QByteArray responseData;
    QEventLoop eventLoop;
    QObject::connect(manager, SIGNAL(finished(QNetworkReply *)), &eventLoop, SLOT(quit()));
    eventLoop.exec();
    responseData = reply->readAll();
    return responseData;
}


QString MainWindow::GetNetIPPconline(QByteArray responseData)
{
    QTextCodec* pTextCodec = QTextCodec::codecForName("GB2312");
      if (NULL == pTextCodec)
      {
            return "";
      }
    QString webCode = pTextCodec->toUnicode(responseData);
    QString ipinfo = "";
    QString web = webCode.replace(" ", "");
    web = web.replace("\r", "");
    web = web.replace("\n", "");
    web = web.replace("\t", "");
    QStringList list = web.split("</form>");
    if(list.count() > 0)
    {
      ipinfo = list;
      list = ipinfo.split("value=");
      ipinfo = list.last();
      list = ipinfo.split("><");
      ipinfo = list;
    }
    return ipinfo.replace("\"","");
}

//获取外网的归属地
QString MainWindow::GetAttributionPconline(QByteArray responseData)
{
    QTextCodec* pTextCodec = QTextCodec::codecForName("GB2312");
      if (NULL == pTextCodec)
      {
            return "";
      }
    QString webCode = pTextCodec->toUnicode(responseData);


//    webCode = webCode.fromLocal8Bit(responseData.data());

    QString attribution = "";
    QString web = webCode; //.replace(" ", "");
    web = web.replace("\r", "");
    web = web.replace("\n", "");
    web = web.replace("\t", "");
    QStringList list = web.split("</form>");
    if(list.count() > 0)
    {
      attribution = list;
      list = attribution.split("<p>");
      attribution = list.last();
      list = attribution.split("</p>");
      attribution = list;
    }
    QStringList addInfo =attribution.split("：");
    if(addInfo.count() > 1){
      return addInfo.trimmed();
    }
    return attribution;
}
调用
qDebug() << GetNetIPPconline(GetHtml("http://whois.pconline.com.cn/"));
    qDebug() << GetAttributionPconline(GetHtml("http://whois.pconline.com.cn/"));只查询外网ip通过　http://www.3322.org/dyndns/getip//获取本机公网IP地址
QString MainWindow::GetNetIP3322(QString webCode)
{
    QString ip = "";
    QString web = webCode.replace(" ", "");
    web = web.replace("\r", "");
    ip = web.replace("\n", "");
    return ip;
}

qDebug() << GetNetIP3322(GetHtml("http://www.3322.org/dyndns/getip"));获取操作系统信息#include <QSysInfo>

QString MainWindow::getOSInfo()
{
    QString osInfo;
    qDebug() << "buildCpuArchitecture: " << QSysInfo::buildCpuArchitecture();
    osInfo = QSysInfo::prettyProductName() +" [" +QSysInfo::productType() +" "+ QSysInfo::productVersion() +"(" + QString::number(QSysInfo::windowsVersion()) + ")]";
    osInfo += " | " + QSysInfo::buildAbi() + " | " + QSysInfo::currentCpuArchitecture() + " | " + QSysInfo::kernelType() + " " + QSysInfo::kernelVersion() + " | " + QSysInfo::machineHostName();
    return osInfo;
}
