http - Exploring Headers and Cookies from Servers (Python)

2004-08-18T10:23:52-07:00

Python recipe 298336 by Michael Foord (cgi). Revision 5.

This CGI script allows you to specify a URL. It fetches the URL and displays all the headers sent by the server. It is based on approx.py the CGI-proxy I'm building. It includes authentication circuitry and I'm using it to understand http authentication.

This script demostrates using urllib2 to fetch a URL - using a request object with User-Agent header. It also demostrates basic authentication and shows the possible http errors - using a dictionary 'borrowed' from BaseHTTPServer.

It will also save cookies using the ClientCookie module, if it's available.

Paypal IPN (Python)

2006-09-19T19:02:54-07:00

Python recipe 456361 by Anthony Barker (cgi). Revision 2.

This is a cgi script that allows you to log an ipn request from paypal. Basically if you configure your paypal account with an ipn url it will send a post to a script url. You need to respond with a post and then will receive a VERIFIED response.

I've included a subroutine to log the data to a database, but you could simply use a text file if that is all you need.

Function to get the user's IP address in a web app or CGI script, even when they're behind a web proxy.

Python Sessions (Python)

2011-01-08T03:23:05-08:00

Python recipe 577524 by Sunjay Varma (cgi, cookie, management, python, security, sessions). Revision 2.

I think this script should now be functional enough to post here at ActiveState. When you reply or vote down, please post some information on your problem with the code, and if you can, maybe something about the solution. This interface works, and is designed especially for Python. If you like it, don't be afraid to post that either, constructive criticism is all good, but compliments are even better! ;)

Get the latest version of this code here: http://wiki.sunjay.ca/Python:Contents/Python_Session

Latest Changes:

Added a new function for making the session cookie last longer. See code for set_expires. Note: This new function is just in case you need to include a session for longer than one brower session (for example, one day instead).

Python Script Viewer (Python)

2005-10-03T18:17:11-07:00

Python recipe 440642 by Stephen Chappell (cgi).

First of all, this code was written to take advantage of the custom CGI module that I wrote. The purpose for this script is to allow someone to view a CGI script through a server. I have the problem that when I click on a python (*.py) file while viewed through my browser, the script is run so that it cannot be viewed. Unless the script is using "cgi.execute(function, exception)", then there is no way of getting around the problem. Therefore, this CGI application was written so that python files (and only *.py files) can be viewed if the user knows either the filename of a file in the same directory as this script or the full path of a file somewhere on the host computer. WARNING: do not use this script if you do not want someone to view any and all python scripts on your computer!

Easy testing of CGI scripts (Python)

2016-11-01T02:27:13-07:00

Python recipe 550822 by Bryan Olson (cgi). Revision 3.

Invoking 'runcgi.py target.cgi' starts a built-in web server listening on the localhost adapter, configures the server to run target.cgi as a CGI program, then launches the system's default web browser to get the URL of the target script. The CGI script need not be in Python. The terminal that launched runcgi.py will show the server's log, which reports requests, responses, and errors.

Traceback that does'nt output on sys.stderr (Python)

2001-06-25T04:25:48-07:00

Python recipe 65332 by Dirk Holtwick (cgi).

For CGI programmers it's important to display tracebacks in the HTML pages to debug their scripts, but the usual functions in the modules cgi and traceback print to sys.sterr. So this small programm returns the traceback as a string an can even add entities for HTML.

"Smart" Links (Python)

2012-07-03T05:05:39-07:00

Python recipe 440647 by Stephen Chappell (cgi).

The following allows someone to create "smart" links on their web site. This is just a simple system and is not very advanced, but it works quite well (given its purpose). If a link is not active (because a server is down), the link is shown as such.
