无效的ISO 8583标头

标签： java android iso8583

我正在尝试解析ISO 8583消息并获取单个数据元素。 下面是我到目前为止尝试过的代码

ISOResponse.java 

public class ISOResponse {
private static final String TAG = "ISOResponse";
private static final String ISOResponseMessage = "60010203040210303800000E8002000000000000000031000046741306511212383334363133303034363734313330363534303036323730353532340012910A59218CDAFBBCD2520014";

public void parseISO8583(final Context context) throws ParseException, IOException {

    MessageFactory<IsoMessage> messageFactory = new MessageFactory<IsoMessage>();

    if (1 == 0) {
        ConfigParser.configureFromDefault(messageFactory);
    } else {

        PrintLog.log(TAG, "Messagefactory is done");

        InputStream inputData = context.getResources().openRawResource(R.raw.j8583_config);

        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputData));

        ConfigParser.configureFromReader(messageFactory, bufferedReader);

    }

    messageFactory.setIgnoreLastMissingField(true);
    IsoMessage isoMessage = messageFactory.parseMessage(ISOResponseMessage.getBytes(),10);
    if (isoMessage != null) {
        PrintLog.log(TAG, "Message type: %04x%n" + isoMessage.getType());
        PrintLog.log(TAG, "FIELD TYPE VALUE");
        for (int i = 2; i <= 64; i++) {
            IsoValue<?> f = isoMessage.getField(i);
            if (f != null) {
                PrintLog.log(TAG, "%5d %-6s [" + i + f.getType());
                PrintLog.log(TAG, f.toString());
                PrintLog.log(TAG, "" + ']');
            }
        }
    }
}
}

此后，我的代码将引发

  

无效的ISO 8583标头

例外。我尝试删除标头数据并在isoMessage中使标头长度为0，但仍然给出相同的异常。

任何人都可以帮助我找到代码错误。 预先感谢。

我尝试解析您的消息，我知道了：

False

看来您的邮件标题长度为14，其中包括 MTI （或10，不含 MTI ）

答案 1 :(得分：0)

我建议使用另一种方法来打包和拆包邮件。 iso-8583-packer允许您将邮件解压缩到以下字段

<f>
    <f name="Header" val="6001020304" valHex="6001020304"/>
    <f name="MTI" val="0210" valHex="0210"/>
    <f name="Bitmap" bitmapHex="303800000E800200" bitSet="{3, 4, 11, 12, 13, 37, 38, 39, 41, 55}">
        <f name="ProcessingCode" fieldNum="3" val="000000" valHex="000000"/>
        <f name="Amount" fieldNum="4" val="000000003100" valHex="000000003100"/>
        <f name="SystemTraceAuditNumber" fieldNum="11" val="004674" valHex="004674"/>
        <f name="LocalTransactionTimeHHMMSS" fieldNum="12" val="130651" valHex="130651"/>
        <f name="LocalTransactionDateMMDD" fieldNum="13" val="1212" valHex="1212"/>
        <f name="PosNumber" fieldNum="37" val="8346130046741" valHex="38333436...36373431"/>
        <f name="ApprovalCode" fieldNum="38" val="306540" valHex="333036353430"/>
        <f name="ActionCode" fieldNum="39" val="06" valHex="3036"/>
        <f name="TerminalId" fieldNum="41" val="2705524" valHex="32373035353234"/>
        <f name="EMV" fieldNum="55" val="910A59218CDAFBBCD2520014" lenHex="0012" valHex="910A5921...D2520014"/>
    </f>
</f>

消息具有以下定义

<f type="MSG">
    <f type="VAL" name="Header" bodyPacker="LiteralBodyPacker" len="5"/>
    <f type="VAL" name="MTI" bodyPacker="BcdBodyPacker" len="2"/>
    <f type="BIT_SET" name="Bitmap" bitMapPacker="IfbBitmapPacker">
        <f type="VAL" fieldNum="3" name="ProcessingCode" bodyPacker="HexBodyPacker" len="3"/>
        <f type="VAL" fieldNum="4" name="Amount" bodyPacker="BcdBodyPacker" len="6"/>
        <f type="VAL" fieldNum="11" name="SystemTraceAuditNumber" bodyPacker="BcdBodyPacker" len="3"/>
        <f type="VAL" fieldNum="12" name="LocalTransactionTimeHHMMSS" bodyPacker="BcdBodyPacker" len="3"/>
        <f type="VAL" fieldNum="13" name="LocalTransactionDateMMDD" bodyPacker="BcdBodyPacker" len="2"/>
        <f type="VAL" fieldNum="37" name="PosNumber" bodyPacker="AsciiBodyPacker" len="13"/>
        <f type="VAL" fieldNum="38" name="ApprovalCode" bodyPacker="AsciiBodyPacker" len="6"/>
        <f type="VAL" fieldNum="39" name="ActionCode" bodyPacker="AsciiBodyPacker" len="2"/>
        <f type="VAL" fieldNum="41" name="TerminalId" bodyPacker="AsciiBodyPacker" len="7"/>
        <f type="LEN_VAL" fieldNum="55" name="EMV" lengthPacker="BcdLengthPacker" bodyPacker="HexBodyPacker"/>
    </f>
</f>

答案 2 :(得分：0)

我知道这是一个老问题，但我最近在使用这个库时遇到了类似的问题，只是想分享这个解决方案，以便它可以帮助其他人。 j8583 config.xml 由两部分组成，用于构建 iso 消息的标记和用于从字符串中解压消息的标记。其中每一个都有子元素字段、类型和子元素 num、类型和长度，用于定义 iso 8583 字段中的每一个。根据经验，使用j8583解析iso消息的最佳方式是使用位图并生成配置文件，然后设置消息工厂。配置 XML 在 j8583.dtd 中导入一组定义的值并用作父标记，此文件存储在服务器中，因此您需要互联网在运行时下载它或自己下载并作为系统导入，如果您是使用 android 或应用程序在与互联网通信时遇到问题，最好将这些定义添加到 [] 中，而不是使用 PUBLIC -path 在这里查看更多信息 https://www.w3schools.com/xml/xml_dtd.asp。同样重要的是，在解析响应时，不要在响应字符串消息中包含其总长度（前 4 个字符）或 tdpu 标头（之后的下 10 个字符）。

构建响应消息配置文件

private void setResponseFactory(String responseMessage) throws IOException {

    Log.i(TAG, "in setResponseFactory");

    StringBuilder xmlParser = new StringBuilder("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
            "<!DOCTYPE j8583-config [\n<!ELEMENT j8583-config ( header*, template*, parse* ) >\n" +

    String messageType = responseMessage.substring(0, 4); // response message type 0210 - sale, 0230 - advice ect...

    Log.i(TAG, "response message type " + messageType);
    Log.i(TAG, "hex bitmap " + responseMessage.substring(4, 20));
    String bitmap =   new BigInteger(responseMessage.substring(4, 20), 16).toString(2);

    int length = 64 - bitmap.length();
    char[] padArray = new char[length];
    Arrays.fill(padArray, '0');
    String padString = new String(padArray);
    bitmap = padString + bitmap; // padd bitmap with zeros to the left

    Log.i(TAG, "response bitmap " + bitmap);

    HashMap<Integer, Pair<IsoType, Integer>> config = new HashMap<>(); // iso response field dictionary

    config.put(Field_Indexes.PRIMARY_ACCOUNT_NUMBER, new Pair<>(IsoType.LLBIN, 0));
    config.put(Field_Indexes.PROCESS_CODE, new Pair<>(IsoType.NUMERIC, 6));
    config.put(Field_Indexes.TRANSACTION_AMOUNT, new Pair<>(IsoType.NUMERIC, 12));

    config.put(Field_Indexes.MESSAGE_AUTHENTICATION_CODE_64, new Pair(IsoType.BINARY, 16));

    xmlParser.append("<j8583-config>\n\t\t<parse type=\"" + messageType + "\">");

    for(int i = 1; i<= 64; i++) // first bitmap if you are using secondary bitmap change to 128 instead of 64
        if(bitmap.charAt(i - 1) == '1')
            xmlParser.append("\n\t\t\t<field num=\"" + i + "\" type=\"" + config.get(i).first.toString() + "\""
                    + ((config.get(i).second > 0) ? " length=\"" + config.get(i).second + "\" ": "")  + "/>");

    wrtieFileOnInternalStorage(xmlParser.toString());

    File root = new File(StateMachine.mContext.get().getFilesDir(),"response");
    File file = new File(root, "isoresponse.xml");

   responseFactory = ConfigParser.createFromClasspathConfig(file.getCanonicalPath());
}

调用消息解析器

    public static void main (String[] args){
        setResponseFactory(responseMessage);
        responseFactory.setUseBinaryMessages(false);

        Log.i(TAG, "in analize response");

        HashMap<Integer, String> isoResponseData = SimpleParser.unpackIsoMessage(responseFactory, responseMessage); // remove tag, tdpu header and trailing 0
}

使用简单解析器https://github.com/SergeyZyazyulkin/j8583/blob/master/src/main/java/com/solab/iso8583/util/SimpleParser.java的实际解包

    public static HashMap<Integer, String> unpackIsoMessage(MessageFactory mf, String message) throws UnsupportedEncodingException, ParseException {

        HashMap<Integer, String> messageValues = new HashMap<>();
        Log.i(TAG, "message: " + message);

        if (message != null && message.length() > 0) {
            IsoMessage m = mf.parseMessage(message.getBytes(), 0);
            if (m != null) {
                for (int i = 2; i <= 128; i++) {
                    IsoValue<?> f = m.getField(i);
                    if (f != null) {

                        Log.i(TAG, "f value class name " + f.getValue().getClass().getSimpleName());

                        if(f.getValue().getClass() == byte[].class)
                            messageValues.put(i, HexCodec.hexEncode((byte[])f.getValue(), 0, ((byte[]) f.getValue()).length));

                        else if(f.getValue().getClass().getSimpleName().equals("Long")){
                            messageValues.put(i, f.getValue() + "");
                        }

                        else
                            messageValues.put(i, (String) f.getValue());

                        Log.i(TAG, "iso value index " + i + " value " + messageValues.get(i));
                    }
                }
            }
        }

        return messageValues;
    }
}
