This Url Shortener provides the basic functions like shortening and expanding links.<br />
|
||
|
|
It is works on the same data structure and provides the same API (see <sup><small>*)</small></sup> below) as urlShort (by mavrev.org)<br />
|
||
|
|
You can enable a preview: if you visit a short URL, then you are not automatically redirected to the target page
|
||
|
|
but you get to see the full link and you can go here manually (this preview is set using a browser cookie).<br />
|
||
|
|
<br />
|
||
|
|
<b>API</b><br />
|
||
|
|
<ul>
|
||
|
|
<li>To expand <sup><small>*)</small></sup> a link:<br /><code><?php echo SERVICE_BASE_URL; ?>/api.php?url=<i><?php echo SERVICE_BASE_URL; ?>SHORT_ID</i></code></li>
|
||
|
|
<li>To expand a link and go to the web page:<br /><code><?php echo SERVICE_BASE_URL; ?><i>SHORT_ID</i></code></li>
|
||
|
|
<li>To expand a link to text:<br /><code><?php echo SERVICE_BASE_URL; ?><i>SHORT_ID.txt</i></code></li>
|
||
|
|
<li>To expand a link to xml:<br /><code><?php echo SERVICE_BASE_URL; ?><i>SHORT_ID.xml</i></code></li>
|
||
|
|
<li>To expand a link to json:<br /><code><?php echo SERVICE_BASE_URL; ?><i>SHORT_ID.json</i></code></li>
|
||
|
|
<li>To display a link as QR-Code (links to short URL):<br /><code><?php echo SERVICE_BASE_URL; ?><i>SHORT_ID.qr</i></code></li>
