QT调用动态库开发IC卡读写程序

 IC卡特点：
1IC卡的内部存储结构分为16个扇区，从第0区到第15区，每个扇区有独立的密码和权限控制字，可作为卡的密码和权限控制字专用独立的电子钱包，每个扇区有4个块，序号为第0块、第1块、第2块、第3块，每块16个字节，第3块是块，禁止在此存放数据。第0块、第1块、第2块可随意存放数据。但第0区的第0块已被固化了IC卡出厂信息，此块只能读出信息，不可更改。

 

调用DLL动态库代码：
   unsigned char result;
    QLibrary mylib("OUR_MIFARE.dll");
    if (!mylib.load())                //判断是否正确加载
    {
        QMessageBox::information(NULL, "提示", "动态库没装载！原因是动态库OUR_MIFARE.dll没放在生成exe文件相同目录下！");
        return;
    }
 
    pcdbeep mypcdbeep = (pcdbeep)mylib.resolve("pcdbeep");
    if (mypcdbeep == NULL)                   //是否成功连接上 idr_beep()函数
    {
        mylib.unload();
        QMessageBox::information(NULL, "提示", "请检查函数名是否正确！");
        return;
 
    }
 
 
    result = mypcdbeep(30);      //这里函数指针调用dll中的idr_beep（) 函数
    mylib.unload();
    if(result > 0)
    {
        if(result == 23)
        {
            QMessageBox::information(NULL, "提示", "机器没连上或者驱动没下载");
        }
        else
        {
            QMessageBox::information(NULL, "提示", "错误代码：" + QString::number(result));
        };
    }

 

读出IC卡数据的代码：

 

void MainWindow::on_pushButton_3_clicked()//轻松读卡
{
   unsigned char ctrlword;//控制字
   unsigned char serial[4];//可写数组
   unsigned char area;//读出的区号
   unsigned char keyA1B0;//AB密码认证

   unsigned char piccdata0_2[48];//下标0~15存放作为读出的块0的数据，下标16~31存放作为读出的块1的数据，下标32~47存放作为读出的块2的数据
   unsigned char status;//返回
   unsigned char status1;
   unsigned char result;
   unsigned char piccdata[16];  //卡数据缓冲

   //以下控制字含义：读块0、块1、块2，仅读指定序列号的卡，需要每次指定密码
   if (ui- >radioButton- >isChecked())
   {
