I have been starting to plan for my next project to come, and felt the need for a function that would use the bit.ly API to shorten URLs for me.
I found a nice Python example over at http://tux-log.blogspot.com, but was not possible to find any AS3 examples. So I spent the evening making my own.
Hope you like it, it’s way from perfect so please feel free to comment!
/**
* Class ShortenURL
* Author: Olle Dahlstrom(olle.dahlstrom@gmail.com)
* Takes a URL and calls the bit.ly API to shorten it.
* You need to have a bit.ly username and API Key(get it at http://bit.ly/), I have my stored in a Config class file.
*
* Example Code
* import net.subelement17.ShortenURL
* var _url:ShortenURL = new ShortenURL();
* _url.call('http://subelement17.net/blog', giveMeTheUrl);
* function giveMeTheUrl(res:String):void)
* {
* //do something with the result....
* }
