我正在尝试使用javax.smartcardio. 问题是我在盲目地做大部分事情，因为我找不到关于APDU commands.目前，我设法打印了卡片类型 ( card: PC/SC card in HID Global OMNIKEY 3x21 Smart Card Reader 0, protocol T=0, state OK) 并读取了卡片识别信息（所选文件0520）。如何下载行驶记录仪 .ddd 文件？这是到目前为止的代码：public static void main(String[] args) { try { TerminalFactory factory = TerminalFactory.getDefault(); List<CardTerminal> terminals = factory.terminals().list(); System.out.println("Terminals: " + terminals); // get the first terminal CardTerminal terminal = terminals.get(0); // establish a connection with the card Card card = terminal.connect("T=0"); System.out.println("card: " + card); CardChannel channel = card.getBasicChannel(); byte[] c1 = hexStringToByteArray(stripCommandSpace("00 A4 04 0C 06 FF544143484F")); //byte[] c1 = hexStringToByteArray(stripCommandSpace("FF CA 00 00 00")); ResponseAPDU r1 = channel.transmit(new CommandAPDU(c1)); System.out.println("response: " + byteArrayToHexString(r1.getBytes())); byte[] c2 = hexStringToByteArray(stripCommandSpace("00 a4 02 0c 02 05 04")); ResponseAPDU r2 = channel.transmit(new CommandAPDU(c2)); System.out.println("response: " + byteArrayToHexString(r2.getBytes())); byte[] c3 = hexStringToByteArray(stripCommandSpace("00 B0 00 01 128")); ResponseAPDU r3 = channel.transmit(new CommandAPDU(c3)); System.out.println("response: " + byteArrayToHexString(r3.getBytes())); System.out.println("data: " + byteArrayToHexString(r3.getData()));我设法识别并读取了驱动程序活动文件 - 我必须将标识符更改为0504如下图所示：现在我的问题是如何将我得到的字节数组转换为 .ddd 文件。我在我的代码的更新版本中尝试过（见上文），但 .ddd 阅读器告诉我文件已损坏（我使用第三方应用程序将 .ddd 转换为 .txt - 称为readesm）。

卡驱动中的结构块：
结构块是（ICC，IC，Application_Identificacion ........）：
标头：“文件 2（0501h，0502h ....）字节”+“类型（数据-0 或有符号-1）1 个字节”+“长度 2 个字节”+ 数据（读卡）：
ICC、IC 和 Card_donwload 不需要签名，所以 0501 到 0522（不是 050e），签名块文件是授权所必需的，但读取字节文件和创建二进制文件不需要。
阅读 Fid 的递归：
for (Fid fid : Fid.values()) {
System.out.println(fid.getId());
// not read 03f00 and 0500 not files
if(!fid.getId().equals("3f,00") && !fid.getId().equals("05,00")){
b = readCard(r, channel, fid.getId());
// header block file
byte[] htba = OperationHelper.hexToByteAr(fid.getId());
byte[] sizeByte = ByteBuffer.allocate(4).putInt(b.length).array();
headerBlock[0] = htba[0]; // id file byte 1
headerBlock[1] = htba[1]; // id file byte 2
headerBlock[2] = 0; // type file data
headerBlock[3] = sizeByte[2]; // size file byte 1
headerBlock[4] = sizeByte[3]; // size file byte 2
try{
fileTGD.write(headerBlock);
fileTGD.write(b);
// add signature file
if (!fid.getId().equals("00,02") && !fid.getId().equals("00,05")
&& !fid.getId().equals("C1,00") && !fid.getId().equals("C1,08")
&& !fid.getId().equals("05,0E")){
performHashFile(r, channel);
b = signature(r, channel);
sizeByte = ByteBuffer.allocate(4).putInt(b.length).array();
headerBlock[0] = htba[0];
headerBlock[1] = htba[1];
headerBlock[2] = 1;
headerBlock[3] = sizeByte[2];
headerBlock[4] = sizeByte[3];
fileTGD.write(headerBlock);
fileTGD.write(b);

5.根据开关内部的文档进行错误处理
