YouTube-like GUID

由 喜夏-厌秋 提交于 2019-11-28 04:29:23
Is it possible to generate short GUID like in YouTube (N7Et6c9nL9w)? How can it be done? I want to use it in web app. You could use Base64: string base64Guid = Convert.ToBase64String(Guid.NewGuid().ToByteArray()); That generates a string like E1HKfn68Pkms5zsZsvKONw== . Since a GUID is always 128 bits, you can omit the == that you know will always be present at the end and that will give you a 22 character string. This isn't as short as YouTube though. eglasius 9 chars is not a Guid. Given that, you could use the hexadecimal representation of an int, which gives you a 8 char string. Update 1:

Find where a t.co link goes to

Given a t.co link, how can I find see where the link resolves? For example, if I have t.co/foo, I want a function or process that returns domain.com/bar. I would stay away from external APIs over which you have no control. That will simply introduce a dependency into your application that is a potential point of failure, and could cost you money to use. CURL can do this quite nicely. Here's how I did it in PHP: function unshorten_url($url) { $ch = curl_init($url); curl_setopt_array($ch, array( CURLOPT_FOLLOWLOCATION => TRUE, // the magic sauce CURLOPT_RETURNTRANSFER => TRUE, CURLOPT_SSL

jQuery on the fly URL shortener

由 家住魔仙堡 提交于 2019-11-27 11:57:43
I'm looking for an on the fly URL shortener much like how tweetdeck works. I have found many jQuery and general javascript plugins that take a url and run it through a shortening service such as bit.ly when a button is pressed. However, I have not been able to find one that does it on the fly. My first question is does this already exist someplace? Secondly, if it doesn't, then what would be the best way to recognize a URL that needs to be shortened inside a textbox? My thoughts: On onKeyUp of that text area run through the text looking for http If found grab the whole URL (how do I determine

How do short URLs services work?

How do services like TinyURL or Metamark work? Do they simply associate the tiny URL key with a [virtual?] web page which merely provide an "HTTP redirect" to the original URL? or is there more "magic" to it ? [original wording] I often use URL shortening services like TinyURL, Metamark, and others, but every time I do, I wonder how these services work. Do they create a new file that will redirect to another page or do they use subdomains? Abel No, they don't use files. When you click on a link like that, an HTTP request is send to their server with the full URL, like http://bit.ly/duSk8wK

How can I unshorten a URL?

由 大城市里の小女人 提交于 2019-11-26 17:42:22
问题 I want to be able to take a shortened or non-shortened URL and return its un-shortened form. How can I make a python program to do this?

If the code is 30x, look at the
