登录Facebook App重定向到画布URL

So I've started learning facebook application and got my first obstacle. Whenever i log into my simple hello user application, i'm redirected into canvas URL (App content opens on server directly, instead inside facebook iFrame).

Here's the code

<?php
require_once("php-sdk/facebook.php");

$config = array(
    'appId' => '',
    'secret' => ''
);

$facebook = new Facebook($config);

$user_id = $facebook->getUser();
$params = array(
    'scope' => 'read_stream, friends_likes',
    'redirect_uri' => 'https://apps.facebook.com/401822713222945/'
);
?>

        <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    </head>

    <body>
<?php
if ($user_id){
    try {
        $user_profile = $facebook->api('/me','GET');
        echo 'Welcome ' . $user_profile['name'] . '!';
    } catch(FacebookApiException $e) {
        $login_url = $facebook->getLoginUrl();
        echo 'Please <a href="' . $login_url . '" onclick="top.location.href = \'' . $login_url . '\'">log in.</a>';
        error_log($e->getType());
        error_log($e->getMessage());
    }
} else {
    $login_url = $facebook->getLoginUrl();
    echo 'Please <a href="' . $login_url . '" onclick="top.location.href = \'' . $login_url . '\'">log in.</a>';
}
?>
    </body>
</html>

    Try the following right after the <body> tag.

    <script type="text/javascript">
if(top === self){
    document.location = "<?php echo $params['redirect_uri'];?>";
}
</script>

    It will check if the current window is the most top window, if you're accessing the page directly it will then redirect you to the iframed page.
