url-shortener

If I have a general url (not restricted to twitter or google) like this: http://t.co/y4o14bI is there an easy way to check if this url is shortened? In the above case, I as a human can of course see that it was shortend, but is there an automatic and elegant way? You could do a request to the URL, look if you get redirected and if so, assume it's a shortening service. For this you'd have to read the HTTP status codes. On the other hand, you could whitelist some URL shortening services (t.co, bit.ly, and so on) and assume all links to those domains are shortened. Drawback of the first method is

This question already has answers here : How do I obfuscate the ids of my records in rails? (5 answers) Closed 4 years ago . I have a web app made with Ruby On Rails. For now when I want to display an object I have to access the following page: http://mywebapp.com/object/1234 with 1234 the id of the object. I would like to encode that object id and have the following result: http://mywebapp.com/object/5k (it is just an example). How can it be done? Many thanks, Martin bender All these converting methods are reversible, so IMHO if your object has some name or title or whatever, then the best

I am looking to unshorten (resolve) a url in python, when the final urls are https. I have seen the question: How can I un-shorten a URL using python? (as well as similar others) , however as noted in the comment to the accepted answer, this solution only works when the urls is not redirected to https. For reference, the code in that question (which works fine when redirecting to http urls) is: # This is for Py2k. For Py3k, use http.client and urllib.parse instead, and # use // instead of / for the division import httplib import urlparse def unshorten_url(url): parsed = urlparse.urlparse(url)

In the days of link shorteners and Ajax, there can be many links that ultimately point to the same content. I was wondering what the best way is to get the final, best link for a web site in PHP, hopefully with a library. I was unable to find anything on Google or GitHub. I have seen this example code, but it doesn't handle things like a rel="canonical" meta tags or default ssl ports: http://w-shadow.com/blog/2008/07/05/how-to-get-redirect-url-in-php/ Facebook seems to handle this pretty well, you can see how they follow 301's and rel="canonical", etc. To see examples of the way Facebook

I'm trying to create a URL shortener service. Most URL shortener services have use a code following the domain. For example, http://bit.ly/duSk8wK , duSk8wK would be the code. What code is needed in .htaccess file to make the server read the path part 'duSk8wK' and query in database, instead of going to the folder name /duSk8wK? Wesley Peeters In your Htaccess, you could make a rewriterule like this: RewriteRule ^([^/.]*)$ redirect.php/?code=$1 [L] Then in your redirect.php , you could simply get the code by using $_GET["code"] . 来源： https://stackoverflow.com/questions/34855381/how-does-url

I am looking into the possibility of shortening / encrypting a url which will be from 150 to 250 characters in length to maximum 12 characters using an algorithm. Initially I am doubting it's possible but I wanted to leverage the great minds of StackOverflow :) the algorithm should be one that can be written in classic asp, sql, c#, vb, or foxpro or other language. Is that even possible without a database centric approach? I was reading here that AES in CFB mode, will do a stream cipher and the output length will be the same as the input length. Is there any way to shorten it even more? The

I'm coding an url shortener function for a project in which I'm learning php, here is the code (btw I suppose that global here is not a good thing to do :P): $alphabet = array(1 => "a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z", "A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z", "0","1","2","3","4","5","6","7","8","9","_","-"); function shorten($id){ global $alphabet; $shortenedId = ""; while($id>0){ $remainder = $id % 64; $id = $id / 64; $shortenedId = $alphabet[$remainder].
