I am trying to fix a fb login error. This code was setup before I started working on the site. Apparently it used to work. I have looked at the fb documentation and the code looks correct. Here is the call:
$token_url = 'https://graph.facebook.com/oauth/access_token?client_id=' . $site->facebook_app_id . '&redirect_uri=' . urlencode('http://' . $site->domain . '/facebook.php?oauth_callback') . '&client_secret=' . $site->facebook_app_secret . '&code=' . get('code');
$token = file_get_contents($token_url);
The response is:
failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request
' in .../facebook.php on line 21
The output of echo $token_url is:
https://graph.facebook.com/oauth/access_token?client_id=#####&redirect_uri=http%3A%2F%2Fdev.mypdxhomes.com%2Ffacebook.php%3Foauth_callback&client_secret= ####&code=AQClZMJ1NUYIwwXUABCw3g8hVhRFavrmQfCr5b-dS6PkVqA40WNfBhQTWHe7V7-q7HUDk2OTS50KGUHEa3TMYADWgkYp688rlSnGNyeetkFYWBuFrWOdeo_wBjdErBQ7n1iNHzetqMvlMtW9KK9TEmnIxmwXEdPl-T3CkRNbGp4g2oCSvXI_ozRo6LWDJMqg6nLq54ibag7k8muhjGZ97CYs
I have looked at a lot of posts about this issue, though none have helped me resolve my issues.
Found the solution to this here: Facebook Access Tokens – Server-Side Authentication
Ended up using the FB PHP SDK
