Facebook app令牌代替用户令牌php sdk

Question

i don't know why when i'm using facebook php sdk 3.1.1 on codeigniter with following code:

...
...
$this->config->load('facebook', TRUE);
$config = $this->config->item('facebook');
$this->load->library('facebook', $config);

echo $this->facebook->getAccessToken();
....

i retrieve app access token instead ( the correct ) user access token.
infact when i try to call

$this->facebook->api('/me')

php return me an error like this

Fatal error : Uncaught OAuthException: An active access token must be used to query information about the current user. thrown in /srv/www/...

i've try to change library version until 3.0, but nothing changed

Anyone know something about that?

Answer 1

/me returns your personal profile info. If you want to query /me , you need to authenticate via a user access token, which is above the app level access token.
