【问题描述】：
我正在尝试解析 ISO 8583 消息并获取各个数据元素。 下面的代码我已经尝试过了
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, "" + ']');
}
}
}
}
}

在这之后我的代码抛出了一个
无效的 ISO 8583 标头
异常。我尝试在isoMessage 中删除标头数据并使标头长度为0，但仍然给出相同的异常。
谁能帮我找出代码中的错误。 提前致谢。
