I am trying to work with a program that is trying make an HTTP POST of text
data without any named form parameter. (I don't know - is that a normal
thing to do?) I need to write a CGI program that accepts and processes that
data. I'm not seeing how to get at data that's not a named form parameter.
I wrote a simple CGI program to echo a string representation of the
cgi.FieldStorage class that's recevied, and one to make an HTTP POST to it
(once with the way I normally encode a "standard" HTML form, and once with
just a multiline string). It doesn't look to me like the FieldStorage class
is exposing anything for me to grab ahold of in the latter case. I don't see
any other likely looking candidates in the cgi module. My program code is
below. Anyone have any suggestions about how to get at raw POST data (as a
CGI program)?
Thanks for taking the time to read my article! :)
