Often, people do require abnormal things.
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.
As far as CGI is concerned, the POST data resides in stdin. So accessing it
is as simple as reading sys.stdin within the CGI script. Of course, it is up
to you to interpret the data, though you can just read everything as a
string. The POST data could just as well be binary - such as a file upload.
To dump the strings to a file to your webserver, try the following script:
import sys
print 'Content-type: text/plain\r\n\r\n'
dumped = open('test.txt', 'wb')
for line in sys.stdin.readline():
dumped.write(line)

cgi: getting at raw POST data?
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! :)
