URL shortener in .net using bit.ly API

It’s simple to generate shorten url based on long url using bit.ly API.

For this we need to have account with http://bit.ly/a/sign_up which is free. After sign up completed, you will be provided with an API key http://bit.ly/a/your_api_key

This API key can be used to access the API. Below is the code for API class in c#

public static class BitlyApi
{
private const string apiKey = "[add api key here]"
;
private const string login = "[add login name here]"
;

public static BitlyResults ShortenUrl(string
longUrl)
{
var url =
string.Format("http://api.bit.ly/shorten?format=xml&version=2.0.1&longUrl={0}&login={1}&apiKey={2}"
,
HttpUtility.UrlEncode(longUrl), login, apiKey);
var resultXml = XDocument.Load(url);
var x = (from result
in resultXml.Descendants("nodeKeyVal"
)
select
new
BitlyResults
{
UserHash = result.Element(
"userHash"
).Value,
ShortUrl = result.Element(
"shortUrl"
).Value
}
);
return
x.Single();
}
}

public class
BitlyResults
{
public string
UserHash { get; set; }

public string ShortUrl { get; set; }
}


Now, we can generate short url as below:


string strShortUrl = BitlyApi.ShortenUrl(“<long url>).ShortUrl;


Happy Coding…

  2. I know improvement's still in advance, however at whatever point you get around to it my supplication is to make a point to graphically speak to the children as fitting. I.e. little and off the beaten path. As of now, they occupy and overpower as they take up such a great amount of room on the page. url shortener google
