如何在ISO8583消息请求中设置子元素
[英]How to set sub-elements in an ISO8583 message request
问题描述
I have a requirement where I need to set some subelements in the private data field 127, specifically subfield 22 and 33. I am unsure of how to actually set the data of field 127 as it needs to contain a bitmap specifying which subfields are populated (in this case only subfield 22 and 33).I have looked through the documentation, but there is not much mention of setting up subfields. 
我有一个需求，我需要在私有数据字段127中设置一些子元素，尤其是子字段22和33。由于不能包含字段127，该字段需要指定填充哪些子字段，我不确定如何实际设置字段127的数据。在这种情况下，仅子字段22和33）。我已经浏览了文档，但是并没有太多提及设置子字段。 Can anyone please guide me on how to do this? 谁能指导我如何执行此操作？

Once you have a reference to an instance of an ISOMsg, you can call: 引用ISOMsg实例后，可以调用：
m.set ("127.22", "XXX");
m.set ("127.33", "YYY");
and 和
m.getString("127.22");
m.getString("127.33");
in order to access those fields. 为了访问这些字段。
As for the subfield configuration, if you're using the GenericPackager, take a look at https://github.com/jpos/jPOS/blob/master/jpos/src/dist/cfg/packager/postpack.xml#L649-L790 至于子字段配置，如果您使用的是GenericPackager，请查看https://github.com/jpos/jPOS/blob/master/jpos/src/dist/cfg/packager/postpack.xml#L649- L790

Are you sure you need a bitmap of secondary fields? 您确定需要辅助字段的位图吗？ The way you usually approach something like this is by using TLVs (Tag Length Value elements). 通常，您使用TLV（“标签长度值”元素）来处理此类问题。
The way you would do that is by having DE 127 as a IFA_LLLCHAR with a content similar to: 03202201012345678900330100987654321. 您可以通过将DE 127作为IFA_LLLCHAR包含类似以下内容的方法来实现：0320220101234567897893030100987654321。
This is equivalent to: 032 (total DE127 length) 022 (tag 22) 010 (length of tag 22) 1234567890 (value of tag22) 033 (tag 33) 010 (length of tag 33) 0987654321 (value of tag 33). 这等效于：032（DE127总长度）022（标签22的长度）010（标签22的长度）1234567890（标签22的值）033（标签33）010（标签33的长度）0987654321（标签33的值）。

I am also facing the same challenge. 我也面临着同样的挑战。 I am using jpos and i am trying to set field 127 sub element 033 as well as unpacking it. 我正在使用jpos，并且尝试设置字段127子元素033以及对其进行解压缩。 My code is as follows: 我的代码如下：
