Question

This exact question has been asked before but I am at my wits end! I’ve spend 4 hours trying to get a SIMPLE Python CGI script to work on Windows XP but I get errors. Please save my sanity!

Python Script register.py

#!c:/Python30/python.exe -u

print "Content-type: text/html" 
print "<P>Hello, World!</p>"

Script is located in:
C:\Program Files\Apache Software Foundation\Apache2.2\cgi-bin\alerter

Apache Error Log:

[Tue Sep 21 19:06:36 2010] [error] [client 127.0.0.1] Premature end of script headers: register.py
[Tue Sep 21 19:06:36 2010] [error] [client 127.0.0.1]   File "C:/Program Files/Apache Software Foundation/Apache2.2/cgi-bin/alerter/register.py", line 3\r

[Tue Sep 21 19:06:36 2010] [error] [client 127.0.0.1] SyntaxError: invalid syntax\r

httpd.conf:

LoadModule cgi_module modules/mod_cgi.so

<Directory "C:/Program Files/Apache Software Foundation/Apache2.2/cgi-bin">
    AllowOverride None
    Options None
    Order allow,deny
    Allow from all
    Options +ExecCGI
    AddHandler cgi-script .py
</Directory>

This should be VERY simple. Yes? I mus be missing that ONE thing that will make it finally work. I got PHP working a while back with no problems.

Any ideas? Thanks!!!

Answer 1

Your error is:

Premature end of script headers

Note that the HTTP protocol specifies that the body of a HTTP response is separated from it’s headers by a blank line (i.e. two times a carriage return and line feed). I’d go for something like:

import sys
sys.stdout.write("Content-type: text/html\r\n\r\n<p>Body</p>")
