在pro文件加了一行
QT += network
  1. #include <QHostAddress>
  2. #include <QNetworkInterface>
  3. QString MainWindow::gethostIp()
  4. {
  5.     QString strIpAddress;
  6.     QList<QHostAddress> ipAddressesList = QNetworkInterface::allAddresses();
  7.     // 获取第一个本主机的IPv4地址
  8.     int nListSize = ipAddressesList.size();
  9.     for (int i = 0; i < nListSize; ++i)
  10.     {
  11.        if (ipAddressesList.at(i) != QHostAddress::LocalHost &&
  12.            ipAddressesList.at(i).toIPv4Address())
  13.        {
  14.            strIpAddress = ipAddressesList.at(i).toString();
  15.            break;
  16.        }
  17.      }
  18.      // 如果没有找到，则以本地IP地址为IP
  19.      if (strIpAddress.isEmpty())
  20.         strIpAddress = QHostAddress(QHostAddress::LocalHost).toString();
  21.      return strIpAddress;
  22. }

  24. QString MainWindow::gethostMac()
  25. {
  26.     QList<QNetworkInterface> nets = QNetworkInterface::allInterfaces();// 获取所有网络接口列表
  27.     int nCnt = nets.count();
  28.     QString strMacAddr = "";
  29.     for(int i = 0; i < nCnt; i ++)
  30.     {
  31.         // 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
  32.         if(nets[i].flags().testFlag(QNetworkInterface::IsUp) && nets[i].flags().testFlag(QNetworkInterface::IsRunning)
  33.                 && !nets[i].flags().testFlag(QNetworkInterface::IsLoopBack))
  34.         {
  35.             strMacAddr = nets[i].hardwareAddress();
  36.             break;
  37.         }
  38.     }
  39.     return strMacAddr;
  40. }

连网状态
  1. bool MainWindow::IPLive(QString ip, int port)
  2. {
  3.     QTcpSocket tcpClient;
  4.     tcpClient.abort();
  5.     tcpClient.connectToHost(ip, port);
  6.     //100毫秒没有连接上则判断不在线
  7.     return tcpClient.waitForConnected(100);
  8. }
  9. 调用  判断百度 80端口是否连通
  10. qDebug() << IPLive("202.108.22.5", 80);
复制代码
外网IP及位置信息　通过网页　http://whois.pconline.com.cn/ 查询解析
  1. #include <QNetworkAccessManager>
  2. #include <QNetworkRequest>
  3. #include <QNetworkReply>
  4. #include <QTextCodec>

  6. QByteArray MainWindow::GetHtml(QString url)

  13.     eventLoop.exec();
  14.     responseData = reply->readAll();
  15.     return responseData;
  16. }


  19. QString MainWindow::GetNetIPPconline(QByteArray responseData)
  20. {
  21.     QTextCodec* pTextCodec = QTextCodec::codecForName("GB2312");
  22.         if (NULL == pTextCodec)
  23.         {
  24.             return "";
  25.         }
  26.     QString webCode = pTextCodec->toUnicode(responseData);
  27.     QString ipinfo = "";
  28.     QString web = webCode.replace(" ", "");
  29.     web = web.replace("\r", "");
  30.     web = web.replace("\n", "");
  31.     web = web.replace("\t", "");
  32.     QStringList list = web.split("</form>");
  33.     if(list.count() > 0)
  34.     {
  35.         ipinfo = list[0];
  36.         list = ipinfo.split("value=");
  37.         ipinfo = list.last();
  38.         list = ipinfo.split("><");
  39.         ipinfo = list[0];
  40.     }
  41.     return ipinfo.replace("\"","");
  42. }

  44. //获取外网的归属地
  45. QString MainWindow::GetAttributionPconline(QByteArray responseData)
  46. {
  47.     QTextCodec* pTextCodec = QTextCodec::codecForName("GB2312");
  48.         if (NULL == pTextCodec)
  49.         {
  50.             return "";
  51.         }
  52.     QString webCode = pTextCodec->toUnicode(responseData);


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

  57.     QString attribution = "";
  58.     QString web = webCode; //.replace(" ", "");
  59.     web = web.replace("\r", "");
  60.     web = web.replace("\n", "");

  70.     }
  71.     QStringList addInfo =  attribution.split("：");
  72.     if(addInfo.count() > 1){
  73.         return addInfo[1].trimmed();
  74.     }
  75.     return attribution;
  76. }
  77. 调用
  78. qDebug() << GetNetIPPconline(GetHtml("http://whois.pconline.com.cn/"));
  79.     qDebug() << GetAttributionPconline(GetHtml("http://whois.pconline.com.cn/"));
复制代码
只查询外网ip  通过　http://www.3322.org/dyndns/getip
  1. //获取本机公网IP地址
  2. QString MainWindow::GetNetIP3322(QString webCode)
  3. {
  4.     QString ip = "";
  5.     QString web = webCode.replace(" ", "");
  6.     web = web.replace("\r", "");
  7.     ip = web.replace("\n", "");
  8.     return ip;
  9. }

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

  3. QString MainWindow::getOSInfo()
  4. {
  5.     QString osInfo;
  6.     qDebug() << "buildCpuArchitecture: " << QSysInfo::buildCpuArchitecture();
  7.     osInfo = QSysInfo::prettyProductName() +" [" +QSysInfo::productType() +" "+ QSysInfo::productVersion() +"(" + QString::number(QSysInfo::windowsVersion()) + ")]";
  8.     osInfo += " | " + QSysInfo::buildAbi() + " | " + QSysInfo::currentCpuArchitecture() + " | " + QSysInfo::kernelType() + " " + QSysInfo::kernelVersion() + " | " + QSysInfo::machineHostName();
  9.     return osInfo;
  10. }
