我需要解包并得到mti,表示数据元素的值
303831308220000002000000040000000000000031313233303930323333303733313536303033303
1个消息字符串。如您所见,mti应该是 3038
但是当我用 isoMsg.getMTI();
它给出的声明 0810
作为输出。那么我的代码有什么问题?请参阅本教程。https://kodejava.org/how-do-i-unpack-an-iso-8583-message/ 在那里前四个领域来作为mti,但我没有得到我的前四个领域作为mti。请提供一个详细的答案。
public class IsoUnpacker {

IsoUnpacker iso = new IsoUnpacker();

4条答案
按热度按时间l0oc07j21#
在你的方法中一切都是好的,每个人都试着解释相同的,但是请允许我先为你澄清基本知识,然后将尝试回答你在op或评论中提出的所有问题。
理解ISO8583(免责声明:我的话&来自维基百科)
它是金融交易消息传递的国际标准。它有一个明确的格式和许多大计划,如万事达卡,签证利用它。根据定义,前4位是mti->消息类型指示符。以此类推,带位置的数字有明确的含义。
基本上定义了这是什么样的信息?现在,如前所述,这是一个标准协议,意味着即使是有效的mti也被定义。所以,在学习或理解ISO8583的同时,你应该开始学习什么是有效的MTI?
现在我强烈建议在进一步阅读之前先阅读这一部分:mti\u wiki
阅读之后,您可能已经理解了-消息类型指示符包括iso8583版本、消息类、消息函数和消息源。也就是说:这4个数字解释了以上3件事。
以您的信息为例:
303831x
现在,如果我们看一下你的信息,再看一下我在上面分享的链接,第一个数字是33038xx
根据iso 8583,不可使用,而是由iso自己保留。这意味着-你最初期望的mti是什么
3038
-甚至不是有效的mti!!这更应该让你意识到,这要么是一个错误的信息,要么是通过某种方式编码的信息。在您的案例中,它是后者,因为它是十六进制编码的消息,这是完全正确的,因为许多业务实体可以选择任何类型的协议。
话虽如此,您必须理解为了使用任何iso库来打包或解包或任何其他东西,您必须首先将您的信息翻译为有效的iso 8583格式。
所以你决定
isoMsg.unpack(ISOUtil.hex2byte(message));
在这种情况下是绝对有效的,当然isoMsg.unpack(message.getBytes());
一定会失败因为当你说message.getBytes()
您没有将有效的iso 8583消息传递给标准解包函数。所以在你的留言里:
Message = 3038313082200000020000000400000000000000313132333039303233333037333135363030333031
具有30383130(十六进制编码)是MTI = 0810
如何知道消息是否为base-16(十六进制编码)?
为此,强烈建议与发起方收单机构/终端/anyinterface达成协议,让消费者/银行/anyinterface知道消息将以何种格式到达。
这些是整个组织的标准实践,这样就可以配置响应者。我敢肯定,从这个发起者那里,你收到的是303831,明天你不会开始收到0810xx(就像ascii一样),除非他们改变了终端的配置/设置,必须通知你/你的公司。至于金融交易的成功,所有具有约束力的当事方都可以发挥作用。
我无法回忆起任何库来检测编码,当然,你可以有一些东西,可以检测,但我仍然要求得到这一标准化,作为双方之间的协议,就像我上面说的。
专业提示:随着时间的推移,你将能够告诉自己的编码或什么样的消息,只要看mti;)!相信我!
希望我回答了你所有的疑问,如果再问也不要犹豫。祝你好运!
col17t5w2#
这是一个有效且格式良好的消息。mti 0810=网络管理响应,字段70,网络管理信息代码,301表示回声测试,字段39=00表示正常,字段11是系统跟踪审核编号,是将响应与请求联系起来的消息的id,字段7是日期和时间,11月23日09:02:33。
位图为8220000000000。数一数,从1开始,得到1,7,11,39和70。字段1是第二个位图。
ISO8583是一个相当松散的标准,每个实现都略有不同。例如,每个卡片品牌都有自己的版本。但这个特殊的例子是标准的。
我没有将其与您提供的参考进行比较,而是与标准的一个版本进行比较。
ffscu2ro3#
这不是一个完整的答案,但它太大了,无法发表评论,可能会帮助你找出问题所在。
注:
这似乎是一个十六进制编码的ascii字符串,在开头附近有一些二进制内容
如果我转换成ascii,而猜测二进制位是32位的小endian整数,我得到
我希望这能帮助你解决问题。
