Graph API: How to grab current user's information?

I'm trying to get some basic information about a user in a PHP script (id and name).

I have tried the following methods:

$retrieve = curl_init("https://graph.facebook.com/me?access_token=$accesstoken");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($retrieve, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOU开发者_如何学PythonT, 10);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$data = curl_exec($retrieve);
curl_close($retrieve);

and

$user = json_decode(file_get_contents(
         "https://graph.facebook.com/me?access_token=$accesstoken"))->me;

The cURL method (former) just times out. The file_get_contents (latter) method just doesn't return anything at all...

What could be causing this? Am I using cURL correctly?

for graph api you can use graph api methods rahter than curl the following code grabs information of current user

define('FACEBOOK_APP_ID', 'Your API ID');
define('FACEBOOK_SECRET', 'YOUR SECRET');
function get_facebook_cookie($app_id, $application_secret)
{
    $args = array();
    parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
    ksort($args);
    $payload = '';
    foreach ($args as $key => $value)
    {
        if ($key != 'sig')
        {
            $payload .= $key . '=' . $value;
        }
    }
    if (md5($payload . $application_secret) != $args['sig'])
    {
        return null;
    }
    return $args;
}
$cookie = get_facebook_cookie(FACEBOOK_APP_ID, FACEBOOK_SECRET);
$user=json_decode(file_get_contents('https://graph.facebook.com/me?access_token='.$cookie['access_token']));

its prettey easy

Facebook will not let you use curl. They have the api for that.

copy your link and paste it to browser. It will work. In Mozilla you will see the result in browser, IE will save the result as a file. So it is not about invalid access token etc. It is just because Facebook does not respond to your query when it does not come 1-from a web browser, 2-from Facebook APIs.

here is the relevant PHP call to Facebook.

$attachment =  array('access_token' => $access_token);
$result=$facebook->api('/me', 'GET', $attachment);
$id = $result['id'];
$name=$result['name'];
