Unshortens a URL and follows recursive redirects

long_url

Overview

This code is designed to unshorten short URLs, follow recursive redirects and output the end destination to the console coupled with the Bluecoat Site Review categorisation of the final URL in the chain. This can be useful if you have several short URLs to examine and need to quickly determine the destination and whether it's perceived by Bluecoat to be malicious.

Install

There are a couple of requirements for the script to run correctly, as detailed in requirements.txt. Installation can be carried out via executing the following:

$ pip install -r requirements.txt

Run

After installing the requirements, simply invoke via the command line, passing in a file containing your short urls as an argument, e.g.

$ python longurl.py -i urls.txt [-b]
    options:
    -i / --infile : specifies the input file containing the urls to examine.
    -b / --bluecoat : specifies whether you wish to perform a bluecoat site review on the destination url.

Example

Some sample URLs are provided in the urls.txt all leading (shamelessly) to my website. They also follow recursive redirects, for example the bit.ly link redirects to goo.gl which redirects to colin.guru.
