easy and simple 8583 Protocol Analysis for java 我的QQ： 534117529 有任何问题，请邮件联系反馈目标是让8583协议更简单，更直观，更好用有多简单？有多直观？参见博客：https://blog.csdn.net/yyz_1987/article/details/80838764 以一个签到报文举例：

/** * 签到报文组帧 * @param field * @param tx */

public void frame8583QD( __8583Fields[] field, Pack tx){

//消息类型
tx.MsgType[0] = 0x08;
tx.MsgType[1] = 0x00;
//11域，受卡方系统跟踪号BCD 通讯流水
field[10].ishave = 1;
field[10].len = 3;
String tmp = String.format("%06d",commSn);
field[10].data = hexStringToBytes(tmp);
//41域，终端号
field[40].ishave = 1;
field[40].len = 8;
field[40].data = PosNum.getBytes();
//42域，商户号
field[41].ishave = 1;
field[41].len = 15;
field[41].data = ManNum.getBytes();
//60域
field[59].ishave = 1;
field[59].len = 0x11;
field[59].data = new byte[6];
field[59].data[0] = 0x00;
arraycopy(piciNum,0,field[59].data,1,3);
field[59].data[4] = 0x00;
field[59].data[5] = 0x30;
//62域
field[61].ishave = 1;
field[61].len = 0x25;
field[61].data = new byte[25];
String str = "Sequence No12";
arraycopy(str.getBytes(),0,field[61].data,0,13);
arraycopy(licenceNum,0,field[61].data,13,4);
arraycopy(PosNum.getBytes(),0,field[61].data,17,8);
//63域
field[62].ishave = 1;
field[62].len = 0x03;
field[62].data = new byte[3];
field[62].data[0] = 0x30;
field[62].data[1] = 0x30;
field[62].data[2] = 0x31;
/*报文组帧，自动组织这些域到Pack的TxBuffer中*/
pack8583Fields(field,tx);

}

/** * 8583签到的响应报文解析 * @param rxbuf * @param rxlen * @return 0，成功非0，失败 */

public int ans8583QD(byte[] rxbuf,int rxlen){

    int ret = 0;
    ret = ans8583Fields(rxbuf,rxlen,fieldsRecv);
    if(ret != 0) {
        //Log.d(TAG,"解析失败！");
        System.out.println("<-Er 解析失败！");
        return ret;
    }
    //Log.d(TAG,"解析成功！");
    System.out.println("->ok 解析成功！");
    //消息类型判断
    if((pack.msgType[0] != 0x08)||(pack.msgType[1]!= 0x10)) {
        //Log.d(TAG,"消息类型错！");
        return 2;
    }
    //应答码判断
    if((fieldsRecv[38].data[0] != 0x30)||(fieldsRecv[38].data[1] != 0x30)){
        //Log.d(TAG,"应答码不正确！");
        //Log.d(TAG,String.format("应答码:%02x%02x",fieldsRecv[38].data[0],fieldsRecv[38].data[1]));
        return 3;
    }
    //跟踪号比较
    if(!Arrays.equals(fieldsSend[10].data,fieldsRecv[10].data)){
        //return 4;
    }
    //终端号比较
    if(!Arrays.equals(fieldsSend[40].data,fieldsRecv[40].data)){
        //return 5;
    }
    //商户号比较
    if(!Arrays.equals(fieldsSend[41].data,fieldsRecv[41].data)){
        //return 6;
    }
    //3DES解密PIN KEY
    byte[] data = new byte[16];
    arraycopy(fieldsRecv[61].data,0,data,0,16);
    byte[] pinkey = DES_decrypt_3(data,hexStringToBytes(mainKey));
    //解密后的结果对8Byte全0做3DES加密运算
    System.out.println("pinkey:"+bytesToHexString(pinkey));
    byte[] tmp= {0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};
    byte[] out =  DES_encrypt_3(tmp,pinkey);
    //对比pincheck是否一致
    byte[] check = new byte[4];
    byte[] pincheck = new byte[4];
    arraycopy(out,0,check,0,4);
    arraycopy(fieldsRecv[61].data,16,pincheck,0,4);
    if(!Arrays.equals(check,pincheck)) {
        System.out.println("<-Er PIK错误");
        return 7;
    }
    else {
        System.out.println("<-ok PIK正确");
    }
    //3DES解密MAC KEY
    arraycopy(fieldsRecv[61].data,20,data,0,16);
    byte[] mackey = DES_decrypt_3(data,hexStringToBytes(mainKey));
    //解密后的结果对8Byte全0做DES加密运算
    System.out.println("mackey:"+bytesToHexString(mackey));
    out =  DES_encrypt(tmp,mackey);

    byte[] maccheck = new byte[4];
    arraycopy(out,0,check,0,4);
    arraycopy(fieldsRecv[61].data,36,maccheck,0,4);
    if(!Arrays.equals(check,maccheck)) {
        System.out.println("<-Er MAC错误");
        return 8;
    }
    else {
        System.out.println("<-ok MAC正确");
        setMacKey(bytesToHexString(mackey));
    }
    //签到成功
    return 0;
}

最终组织好的报文在哪呢？在报文结构类Pack中的Txbuffer中，长度为Txlen

需要外部设置的参数在哪放？

外部需要配置的有：终端号，商户号，主秘钥，TPDU。这些在类里定义的有set和get方法。如何使用？如何发送报文给银联后台呢？

假如你通信有Send（byte[] sendbuf, int len）方法

那么只需 Send（pack.TxBuffer,pack.TxLen）

想打印出来报文日志在哪看？直接pack.ToString()即可

附带一个调用的demo:

/** * 调用demo * @param args */

public static void main(String[] args) {
    My8583Ans myans = new My8583Ans();
    //签到组包
    myans.frame8583QD(myans.fieldsSend,myans.pack);
    //打印出待发送的报文
    byte[] send = new byte[myans.pack.txLen];
    arraycopy(myans.pack.txBuffer,0,send,0,myans.pack.txLen);
    System.out.println("->send:");
    System.out.println(My8583Ans.bytesToHexString(send));
    System.out.println(myans.pack.toString());
    System.out.println(myans.getFields(myans.fieldsSend));
    //接收解析,假如收到的报文在recv中
    String recvstr ="007960000001386131003111080810003800010AC0001450021122130107200800085500323231333031343931333239303039393939393930363030313433303137303131393939390011000005190030004046F161A743497B32EAC760DF5EA57DF5900ECCE3977731A7EA402DDF0000000000000000CFF1592A";
    System.out.println("->recv:"+recvstr);
    byte[] recv = My8583Ans.hexStringToBytes(recvstr);
    // mypack.ans8583Fields(bt,bt.length,mypack.fieldsRecv);
    //解析
    System.out.println("开始解析...");
    int ret = myans.ans8583QD(recv,recv.length);
    if(ret == 0){
        //打印出解析成功的各个域
        System.out.println("签到成功!");
        System.out.println(myans.getFields(myans.fieldsRecv));
    }

    //二维码组包
    System.out.println("->二维码交易 demo");
    String qrcode = "6223360612494957384";
    int money = 1; //1分
    myans.frame8583Qrcode(qrcode,money,myans.fieldsSend,myans.pack);
    //打印出待发送的报文
    send = new byte[myans.pack.txLen];
    arraycopy(myans.pack.txBuffer,0,send,0,myans.pack.txLen);
    System.out.println("->send:");
    System.out.println(My8583Ans.bytesToHexString(send));
    System.out.println(myans.pack.toString());
    System.out.println(myans.getFields(myans.fieldsSend));
}
