Intermittent warning with file_get_contents() OpauthStrategy.php, line 402 about facebook

Looks like you're getting an Error 400: Bad Request from Facebook Graph API.

If it fails only some of the time, then it could be Facebook API that's having a problem during that time.

However, you might also want to check if you have openssl enabled at your PHP.

Could you provide some more information, opauth response should contain additional info like seen here:

the error is:

    'error' => array(
        'provider' => 'Facebook',
        'code' => 'access_token_error',
        'message' => 'Failed when attempting to obtain access token',
        'raw' => 'HTTP/1.0 400 Bad Request

    ),

)

Invalid code error? it is impossible. I used correct app credentials.

(I only checked Website with Facebook Login in the app settings)

You are not supposed to reuse the one-time authorization code.

To reauthenticate user, start from the beginning, eg. /auth/facebook

[dall]

sure, i always start with /auth/facebook

uzyn, maybe i found the problem:

in my AppController i have:

    public $components = array(
        /*'Security',*/
        'Session',
        'Auth' => array(
            'loginAction' => array(
                'controller' => 'users',
                'action'     => 'login'
            ),    
            'logoutRedirect' => array(
                'controller' => 'pages',
                'action'     => 'home'
            ),
            'authenticate' => array(
                'OpAuth',
                'Login',
            ),
            'authorize' => array('Controller')
        )
    );

if i comment 'authorize' => array('Controller') it works correctly! (always).... now i have to understand why this problem.... maybe my custom Authenticate class?
