[javascript]Google URL Shortener API
Googleの短縮URL「goo.gl」がAPIの提供を開始http://blog.fkoji.com/2011/01110730.html
したらしいので早速いじってみました。
あらかじめ下記サイトでAPIキーを取得しておきましょう。
URL Shortener APIのActivateボタンを押して表示されたURLのkeyの値がAPIキーです。
http://code.google.com/apis/console/
APIキーを取得したらあとはごりごり書くだけ。
PHP
< ?php
$apikey='APIキー';
$url="https://www.googleapis.com/urlshortener/v1/url" . '?key=' . $apikey;
$longurl=$_GET["longUrl"];
$shorturl=$_GET["shortUrl"];
if($longurl){
$request='{"longUrl": "' . $longurl . '"}';
$headers = array('Content-Type:application/json');
$conn = curl_init();
curl_setopt($conn, CURLOPT_URL, $url);
curl_setopt($conn, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($conn, CURLOPT_POSTFIELDS, $request);
curl_setopt($conn, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($conn, CURLOPT_POST, true);
curl_setopt($conn, CURLOPT_HEADER, false);
curl_setopt($conn, CURLOPT_HTTPHEADER, $headers);
}elseif($shorturl){
$url .= '&shortUrl=' . $shorturl;
$conn = curl_init();
curl_setopt($conn, CURLOPT_URL, $url);
curl_setopt($conn, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($conn, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($conn, CURLOPT_HEADER, false);
}else{
echo "error";
exit;
}
$ret=curl_exec($conn);
echo $ret;
curl_close($conn);
exit;
?>
Javascript
//短縮するとき
var m={'longUrl':対象URL};
ajax_get('action.php', m, when_get_shorturl);
//元に戻すとき
var m={'shortUrl':対象URL};
ajax_get('action.php', m, when_get_longurl);
function when_get_shorturl(data){
var m=eval("("+data+")");
}
function when_get_longurl(data){
var m=eval("("+data+")");
}
function ajax_get(cgi_path, param, finish_func){
var httpObj = createHttpRequest();
if(!httpObj)return;
var str=get_post_param(param);
if(str!="")cgi_path+=('?'+str);
httpObj.open("GET",cgi_path, true);
httpObj.onreadystatechange=function(){
if(httpObj.readyState == 4 && httpObj.status == 200){
var data=httpObj.responseText;
finish_func(data);
}
}
httpObj.setRequestHeader('Content-Type','application/x-www-form-urlencoded; charset=UTF-8');
httpObj.send();
}
function get_post_param(param){
if(!param)return "";
var a;
var str="";
var m;
var b;
for(b in param){
str+=b+"="+encodeURIComponent(param[b]);
str+="&";
}
str=str.substring(0,str.length-1);
return str;
}
function createHttpRequest(){
var x=null;
if (window.XMLHttpRequest)return new XMLHttpRequest();
try {
return new ActiveXObject("Msxml2.XMLHTTP");
} catch(e) {
try {
return new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
x = null;
}
}
return x;
}
