網(wǎng)絡(luò)讀卡器qt代碼示例，包含獲取本地ip地址。讀取IC卡卡號(hào)，讀取扇區(qū)數(shù)據(jù)

獲取本機(jī)所有的網(wǎng)卡IP：

bool listening=false;
QTcpServer m_server;
QTcpSocket m_socket;
QStringList getAllIPAddresses() {
   QStringList ips;
   QList list = QNetworkInterface::allAddresses();
   for (int i = 0; i < list.size(); ++i) {
       QHostAddress address = list.at(i);
       // 檢查是否為IPv4地址，并排除回環(huán)地址
       if (address.protocol() == QAbstractSocket::IPv4Protocol && address != QHostAddress::LocalHost) {
           ips 
//解析讀取IC卡卡號(hào)-------------------------------------------------------------------------------------------------------------------
void MainWindow::Analyze_c1(QHostAddress ip,quint16 port,unsigned char databuff[], qint64 buflen)
{
   DisableSendAgain(ip, port,databuff,buflen);//確認(rèn)接收到的信息，否則同一信息讀卡器會(huì)重發(fā)三次
   QString IPAddress=QString::asprintf("%d", databuff[1])+"."+QString::asprintf("%d", databuff[2])+"."+QString::asprintf("%d", databuff[3])+"."+QString::asprintf("%d", databuff[4]); //設(shè)備IP地址,廣域網(wǎng)上使用，一般不對(duì)此IP回應(yīng)，而是對(duì)數(shù)據(jù)流的 ip及端口 回應(yīng)
   QString DeviceNumber=QString::asprintf("%05d",databuff[5]+databuff[6]*256);   //設(shè)備自編機(jī)號(hào)
   QString FrameNumber=QString::asprintf("%05d",databuff[7]+databuff[8]*256);    //數(shù)據(jù)包號(hào)
   QString CardnoHexZ=QString::asprintf("%02X%02X%02X%02X", databuff[10],databuff[11],databuff[12],databuff[13]);  //16進(jìn)制卡號(hào)正碼
   QString CardnoHexF=QString::asprintf("%02X%02X%02X%02X", databuff[13],databuff[12],databuff[11],databuff[10]);  //16進(jìn)制卡號(hào)反碼
   bool status;
   QString Cardno8H10D=QString::asprintf("%010u",CardnoHexF.toUInt(&status,16));  //轉(zhuǎn)8H10D反碼卡號(hào)
   QString SerialNumber="";        //設(shè)備全球唯一硬件序號(hào)
   for (int i=14;itextEdit_M1UID->setText(CardnoHexZ);
   if(ui->checkBox_Resp->isChecked()){Respondinfo(getsysdatetime()+"卡號(hào):"+Cardno8H10D,ip,port,DeviceNumber);}  //回應(yīng)驅(qū)動(dòng)設(shè)備顯示+蜂鳴響聲
}
主動(dòng)讀取扇區(qū)數(shù)據(jù)的返回-
void MainWindow::Analyze_c3(QHostAddress ip,quint16 port,unsigned char databuff[], qint64 buflen)
{
   QString IPAddress=QString::asprintf("%d", databuff[1])+"."+QString::asprintf("%d", databuff[2])+"."+QString::asprintf("%d", databuff[3])+"."+QString::asprintf("%d", databuff[4]); //設(shè)備IP地址,廣域網(wǎng)上使用，一般不對(duì)此IP回應(yīng)，而是對(duì)數(shù)據(jù)流的 ip及端口 回應(yīng)
   QString DeviceNumber=QString::asprintf("%05d",databuff[5]+databuff[6]*256);   //設(shè)備自編機(jī)號(hào)
   QString CardnoHex="";
   for (int i=12;i=databuff[9]){
       m=databuff[9]*48;
       QString DataHex="";
       for (int i=0;itextEdit_data->setPlainText(DataHex);
       QString DispInf="讀取M1卡扇區(qū)數(shù)據(jù)成功，設(shè)備IP："+IPAddress+",機(jī)號(hào)："+DeviceNumber+",16進(jìn)制卡號(hào)："+CardnoHex;
       listadditems(1,DispInf);
       ui->textEdit_M1UID->setText(CardnoHex);
       if(ui->checkBox_Resp->isChecked()){Respondinfo(getsysdatetime()+"卡號(hào):"+CardnoHex,ip,port,DeviceNumber);}  //回應(yīng)驅(qū)動(dòng)設(shè)備顯示+蜂鳴響聲
   }
}
