CGI Scripts
The [http://www.python.org/doc/current/lib/module-cgi.html cgi module] is at the core of the Python CGI scripts.
Basically, you just need to print out an HTTP header ("Content-type: text/html"), a web page, and handle any forms you may have received.
Getting Apache's permissions just right can be annoying, and is sadly beyond this page's scope.
Sample Code
1 #!/usr/bin/env python
2
3 import cgi
4 import cgitb; cgitb.enable() # for troubleshooting
5
6 print "Content-type: text/html"
7 print
8
9 print """
10 <html>
11
12 <head><title>Sample CGI Script</title></head>
13
14 <body>
15
16 <h3> Sample CGI Script </h3>
17 """
18
19 form = cgi.FieldStorage()
20 message = form.getvalue("message", "(no message)")
21
22 print """
23
24 <p>Previous message: %s</p>
25
26 <p>form:</p>
27
28 <form method="post" action="index.cgi">
29 <p>message: <input type="text" name="message"/></p>
30 </form>
31
32 </body>
33
34 </html>
35 """ % message
