FIX消息定界符 [英] FIX message delimiter
问题描述
我对FIX协议比较陌生.
I am relatively new to FIX-Protocol.
FIX协议消息的分隔符有时显示^,而其他时候显示|. FIX-协议的维基百科说 [SOH]
(十六进制0x01的< 标头开始 >)是字符.
The delimiter for a FIX-Protocol message sometimes show ^ and other times |. Wikipedia for FIX-Protocol says [SOH]
( <Start of Header> for hex 0x01 ) being the character.
请解释一下含义.
例如,FIX协议消息可以可视化表示为
For example a FIX-Protocol message can be visually represented as
8=FIX.4.4^9=122^35=D^34=215^49=CLIENT12^52=20100225-19:41:57.316^56=B^1=Marcel^11=13346^21=1^40=2^44=5^54=1^59=0^60=20100225-19:39:52.020^10=072^
或
8=FIX.4.4|9=122|35=D|34=215|49=CLIENT12|52=20100225-19:41:57.316|56=B|1=Marcel|11=13346|21=1|40=2|44=5|54=1|59=0|60=20100225-19:39:52.020|10=072|
那么使用^ over |到底有什么区别?
So what exactly is the difference in using a ^ over |
是否也使用其他定界符.目前尚不清楚为什么 [SOH]
(0x01)适合^或|
Are there other delimiters used as well. Its not clear why [SOH]
(0x01) fits for ^ or |
它可能是数字1.
推荐答案
定界符SOH = ASCII代码01是不可打印的字符.查看消息的二进制表示形式(例如,在十六进制编辑器视图中),您会看到字符为0x01.为了显示消息,似乎有些人使用|
,而另一些人使用^
,这些字符很少使用,因此是一个很好的定界符.
The delimiter SOH = ASCII code 01 is a non-printable character. Looking at the binary representation of the message (e.g. in a hex editor view), you'll see the character as 0x01. To display the messages, it seems that some people use |
and other use ^
which are rarely used characters and thus a good delimiter.
