Shorten URL in Flex using bit.ly
Filed Under (Coding) by Olle on 02-08-2009
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....
* }

package net.subelement17

import mx.rpc.events.ResultEvent;
import mx.rpc.http.HTTPService;
public class ShortenURL
{
private var apiKey:String = new Config().bitly_APIKKEY;
private var userName:String = new Config().bitly_USERNAME;
private var apiVersion:String = new Config().bitly_APIVERSION;
public var longURL:String = ''
private var resultReturn:Function;
public function ShortenURL(){}
public function call(URL:String,resultHandler:Function):void

resultReturn = resultHandler;
longURL = URL;
var htService:HTTPService = new HTTPService();
htService.method = 'GET';
htService.resultFormat = 'array';
htService.url = 'http://api.bit.ly/shorten';
var params:Object = new Object();
params.longUrl = URL;
params.login = userName;
params.apiKey = apiKey;
params.version = apiVersion;
params.format = 'xml';
htService.addEventListener(ResultEvent.RESULT,resutlHander);
htService.send(params);
}
private function resutlHander(resultEV:ResultEvent):String
{
var shortXML:XML = new XML(resultEV.message.body);
if(shortXML.child("errorCode").toString() == 0)
{
return resultReturn(shortXML.child("results").child('nodeKeyVal').child("shortUrl").toString());
}
else
return resultReturn(longURL);
}
}
}
hey frnd ,
I have made small modification in your code and used in flex, but it is not working even i’m using correct apikey.
Its gives error
203
You must be authenticated to access shorten
ERROR
PLZ SEE MY CODE IN FLEX
plz check the code using your apikey and usrname and tell me the solution.
thx in advanced,
:)
Hello Abhishek
It works just fine for me(see example below on how to call it). Have you activated the API to get the correct API key in bit.ly?
