我正在尝试解压缩ISO8583消息。我用来尝试解压缩的简单代码如下：

代码语言：javascript
复制
    String message = "0100767C64C1A8E0B8231047611400000001530100000000000105000000002364330418190929522517452144201409220418221260110250002100040465010B092500026401204761140000000153D22122011320401538313731323035353838323541544D3131303120424444462020202020202020202020445552414E445C50415249535C373530303720202020202020202020202020202020202020204652097804849B22C88200C53DCD0A0160320101000100110112010002010001020116020001700205020250203036376531303961306333643464353539366235376236346562643536326231C6F66DB200000000";            
                byte[] b = message.getBytes(ISOUtil.CHARSET);
                GenericPackager packager = new 
    GenericPackager("sample_packager.xml");
                ISOMsg isoMsg = new ISOMsg();
                isoMsg.setPackager(packager);
                isoMsg.unpack(b);

在我应该解压缩的消息中，LLVAR类型类的长度是十六进制，但数据是ASCII。例如，在这种情况下，字段2是104761140000000153.长度10是十六进制，实际上是接下来的16个数据。我怎么去解释这个呢？我可以将哪个jpos类用于PAN字段，这样我可以将数据保存为ASCII但仍然以十六进制而不是十进制为长度？

注意：

很容易，目前的位是2,3,4,6,7,10,11,12,13,14,18,19,22,25,26,32,33,35,37,41,42,43 ，49,51,52,53,59,63,64。

很可能你的消息是二进制消息，你似乎需要一个基于iso87binary.xml而不是iso87ascii.xml的打包器。

但是你需要用IFB_LLHNUM来改变IFB_LLNUM，这意味着长度的二进制前缀，而不是BCD（IFB）。

代码语言：javascript
复制
    public static void main(String[] args) throws ISOException {

        String message = "0100767C64C1A8E0B8231047611400000001530100000000000105000000002364330418190929522517452144201409220418221260110250002100040465010B092500026401204761140000000153D22122011320401538313731323035353838323541544D3131303120424444462020202020202020202020445552414E445C50415249535C373530303720202020202020202020202020202020202020204652097804849B22C88200C53DCD0A0160320101000100110112010002010001020116020001700205020250203036376531303961306333643464353539366235376236346562643536326231C6F66DB200000000";
        byte[] b = ISOUtil.hex2byte(message);
        GenericPackager packager;
                packager = new
                        GenericPackager("sample_packager.xml");
        Logger logger = new Logger();
        logger.addListener(new SimpleLogListener());
        packager.setLogger(logger, "packager");
        ISOMsg isoMsg =
                new ISOMsg();
        isoMsg.setPackager(packager);
        isoMsg.unpack(b);


    }

打包机的第一行看起来像

通过对“sample_packager.xml”的这种修改，第一个字段将如下所示：
