API Stuff / 短连接API
We actually have an API for the LiURL site, although I haven’t really documented it that well as of yet. As we’re a brand new site, we’re busy building in functionality, so this will get expanded in further posts as we add features.
To get a Shortened URL (aka Little URL) , the call is this:
http://liurl.cn/api-create.php?url=
Which returns the short URL. If you’ve been naughty and haven’t passed a valid URL, then it will return you a big fat -1 for your efforts.
Strangely enough, we also have the diametrically opposite call of that, which (suprise suprise) gives you a long URL from a shortened one
http://liurl.cn/api-create.php?tinyurl=
This also returns a -1 failure if the URL isn’t one we know about.
Some sample PHP code after the break
虽然我目前仍未正式书面记录，不过在LiURL网站 我们已经使用了API。由于我们是新建的品牌网站，目前我们正忙于建设网站的功能性。所以这部分我们将在以后增加网站新特性时候加以扩充。
如果需要缩短后的链接 如下所示
http://liurl.cn/api-create.php?url=
它将返回缩短后的链接。如果您没有通过正规的链接那么将会出现大大的 -1错误提示。
奇怪的是，我们也遇到了完全相反的情况，有时它会从短链接提供一个长链接（非常奇怪）。
http://liurl.cn/api-create.php?tinyurl=
如果链接不正确 它同样也会出现 -1 错误提示。
以下是一些错误后的PHP编码样本。
Example PHP Code:
function process($url,$postargs=false) {
$username=”; $password=”;
$ch = curl_init($url);
if($postargs !== false) {
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postargs);
}
if(username !== false && password !== false)
curl_setopt($ch, CURLOPT_USERPWD, username.‘:’.password);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_NOBODY, 0);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
$responseInfo=curl_getinfo($ch);
curl_close($ch);
if( intval( $responseInfo[‘http_code’] ) == 200 )
return $response;
else
return false;
}
function shorturl( $url ) {
$request = ‘http://liurl.cn/api-create.php?url=’ . $url;
process( $request );
}
function longurl ($url) {
$request = ‘http://liurl.cn/api-create.php?tinyurl=’.$url;
process( $request );
}
$shorty = shorturl (‘http://www.liurl.cn’);
print "Show me the money: " . $shorty ;
$longy = longurl ($shorty);
print "Guess what this url is: ". $shorty. " = " . $longy;
?>
Can you check the process function again, I get
Fatal error: Using $this when not in object context in /Users/alex/Sites/testtiny.php on line 10
Can’t fix it myself, don’t really understand the script.
