java - Pcsc -smartcard 获取 UID

Question

我正在尝试读取卡 UID/HCE来 self 的 pcsc java 代码的 android 设备 UID。但我收到以下错误

javax.smartcardio.CardException: sun.security.smartcardio.PCSCException: Unknown error 0x1f

虽然我在尝试获取 UID 时能够获取 ATS 位，但我收到了此错误。我从 here 引用了我的代码

已经提到了以下内容 Get UID of Mifare Ultralight with SCL010

请帮忙!

谢谢

Answer 1

我能够通过更改命令 APDU 找到解决方案并获取 UID。然后我将结果 byte[] 转换为十六进制 UID。

try {
                //get UID cmd apdu
                 ResponseAPDU answer = cc.transmit( new CommandAPDU(new byte[] { (byte)0xFF, (byte)0xCA, (byte)0x00, (byte)0x00, (byte)0x00 } ));

                   System.out.println("answer: " + answer.toString());

                   byte[] reponseBytesArr=answer.getBytes();

                   System.out.println("answer byte[]");
                   StringBuilder sb = new StringBuilder();

                   for(int i=0;i<reponseBytesArr.length;i++){
                       //print arr
                       byte b =reponseBytesArr[i];
                       System.out.println(b);
                       if(i<=reponseBytesArr.length-3){
                        // append uid
                       sb.append(String.format("%02X ", b));
                       }
                }    
                    System.out.println("UID: "+sb.toString());
