Getting long-lived access token with setExtendedAccessToken() returns short lived token
facebook-php-sdk, php
Solution
@Julian. Thank you so much for the inspiration here. I was able to make this work without changing any of the core FB api files.
What happens is, the `setExtendedAccessToken` call sends the value to `setPersistentData` which then sends it into session via `constructSessionVariableName`.
So if we get it out of session, and then set it into the facebook object, we're all set.
Here is my code:
// ask for the extended token and get it from session ...
$facebook->setExtendedAccessToken();
$access_token = $_SESSION["fb_".FB_APP_ID."_access_token"];
// now set it into the facebook object ....
$facebook->setAccessToken($access_token);
// now our fb object will use the new token as usual ...
$accessToken = $facebook->getAccessToken();
Problem
I try to get extended long-lived access token with ``` $facebook->setExtendedAccessToken(); $access_token = $facebook->getAccessToken(); ``` After looking SDK I found that setExtendedAccessToken() function is setting long-lived access token in ``` protected static $kSupportedKeys = array('state', 'code', 'access_token', 'user_id'); ``` with ``` $this->setPersistentData( 'access_token', $response_params['access_token'] ); ``` and getAccessToken() is returning short-lived access token from ``` protected $accessToken ``` so what is the purpose of setExtendedAccessToken() since it does not return anything?
