想要取得粉絲專頁(粉絲團頁面)的公開資訊，以及該粉絲團最新一筆主題該怎麼做呢？
這邊分成三種版本來講：PHP、jQuery 與 C#.NET。
※由於粉絲專頁幾乎是公開資訊，從 Graph API 就可取得。因此其實也可以不用做 app，直接就可以透過 Graph API 撈取。這邊只有 PHP 是用老作法。
PHP
嗯，您要先下載官方的 PHP SDK。就是 facebook.php 這隻。
然後不多說 .. 直接看 Code 吧。
<?php
require ‘./facebook.php’;
$facebook = new Facebook(array(
‘appId’ => ‘APP ID’,
‘secret’ => ‘SECRET KEY’,
‘cookie’ => true, // enable optional cookie support
));
// 取得粉絲團相關資訊
function getPageInfo($page) {
$fbpageinfo = ”;
global $facebook;
try {
$fbpageinfo = $facebook->api("/$page");
}
catch(Exception $o) {
//print_r($o);
}
return $fbpageinfo;
}
// 取得粉絲團最新一筆話題
function getPageTopic($page) {
$fbpagetopic = ”;
global $facebook;
try {
$fbpagetopic = $facebook->api("/$page/posts?limit=1");
}
catch(Exception $o) {
//print_r($o);
}
return $fbpagetopic;
}
// 擷取部分字串後加刪節號
function textLimit($string, $length, $replacer = ‘…’)
{
if(strlen($string) > $length)
return (preg_match(‘/^(.\*)\\W.\*$/’, mb_substr($string, 0, $length+1, ‘UTF-8’), $matches) ? $matches\[1\] : mb_substr($string, 0, $length, ‘UTF-8’)) . $replacer;
return $string;
}
?>

</html>jQuery
再來是 jQuery 版本 .. 其實只是 JSON 去撈而已 XD

這邊有使用到 JSON.NET 元件(Newtonsoft.Json.Net35.dll)

}最後再補充一個 Facebook Graph Toolkit for .NET 的作法
是使用 Facebook Graph Toolkit 這個元件，這邊使用的是 Facebook Graph Toolkit 1.1 for .Net 3.5 這包。嗯..這樣比起上面那樣搞剛的做法好多了 XD
