The cgi module
This module provides a number of support functions and classes for common gateway interface (CGI) scripts. Among other things, it can parse CGI form data.
Here’s a simple CGI script that returns a list of a files in a given directory (relative to the root directory specified in the script).
Example: Using the cgi module
# File: cgi-example-1.py import cgi import os, urllib ROOT = "samples" # header print "text/html" print query = os.environ.get("QUERY_STRING") if not query: query = "." script = os.environ.get("SCRIPT_NAME", "") if not script: script = "cgi-example-1.py" print "<html>" print "<head>" print "<title>file listing</title>" print "</head>" print "</html>" print "<body>" try: files = os.listdir(os.path.join(ROOT, query)) except os.error: files = [] for file in files: link = cgi.escape(file) if os.path.isdir(os.path.join(ROOT, query, file)): href = script + "?" + os.path.join(query, file) print "<p><a href='%s'>%s</a>" % (href, cgi.escape(link)) else: print "<p>%s" % link print "</body>" print "</html>"
text/html <html> <head> <title>file listing</title> </head> </html> <body> <p>sample.gif <p>sample.gz <p>sample.netrc ... <p>sample.txt <p>sample.xml <p>sample~ <p><a href='cgi-example-1.py?web'>web</a> </body> </html>
