如何发送带有ISO8583前缀的消息 [英] How do I send a ISO8583 prefixed message

问题描述

Hello All，



我在C＃的pos终端上写POS应用程序，我需要发送

ISO 8583消息数据包到银行的主机服务器运行Postilion

Termapp。我能够使用API​​

成功打包消息并使用serversocket发送到服务器。但是我的挑战是，银行的规范说，一个2字节的标题是为所有发送到/来自Postilion的消息前缀

。拜托，我该如何解决这个问题？



我的尝试：



这是我的留言：

Hello All,

I am writing a POS application on a pos terminal in C# where i need to send
ISO 8583 message packet to bank's host server running Postilion
Termapp. I was able to successfully packed the message using the APIs
and send to the server using the serversocket. But my challenge is that
the bank's spec says that a 2-byte header is to prefixed all messages
sent to/from Postilion. Please, how do i go about this?

What I have tried:

This is my Message:

ISO0160000500800822000000000000004000000000000000401093254325642001

但是银行要求带有这个两字节标题的消息： \ 0C

but the bank require the message with this two byte header: "\0C"

\0CISO0160000500800822000000000000004000000000000000401093254325642001

显然并非总是相同我想知道如何计算它。

obviously not always is the same I want to know how to calculate it.
