Cannot catch an Exception while authenticating user with HybridAuth - php

Question

I'm creating a WordPress plugin that automatically publishes the post to Facebook when a new post is added to the site. For the same reason user needs to authenticate his Facebook account. The code I use for this purpose is:-
try {
$fp_hybridauth = new Hybrid_Auth( $hybrid_config );
$fp_hybridauth->authenticate( "facebook" ); //this function does the job of authenticating user and it is causing the exception to be thrown
update_option( "session_data", $fp_hybridauth->getSessionData() );
wp_redirect( site_url("/wp-admin/admin.php?page=facebook-publish&tab=api&fbauth=success") );
}
catch( Exception $e ){
echo $e->getMessage();
}
This code works perfectly if user permits the permission in Facebook oAuth dialog, but if user denies to give permission, it throws an exception that I can't seem to catch:-
Fatal error: Uncaught exception 'Exception' with message 'Authentication failed! The user denied your request.' in /home/pramodjodhani/public_html/dev/wp-content/plugins/facebook-publish/lib/class/hybridauth/Hybrid/Providers/Facebook.php:86 Stack trace: #0 /home/pramodjodhani/public_html/dev/wp-content/plugins/facebook-publish/lib/class/hybridauth/Hybrid/Endpoint.php(182): Hybrid_Providers_Facebook->loginFinish() #1 /home/pramodjodhani/public_html/dev/wp-content/plugins/facebook-publish/lib/class/hybridauth/Hybrid/Endpoint.php(58): Hybrid_Endpoint::processAuthDone() #2 /home/pramodjodhani/public_html/dev/wp-content/plugins/facebook-publish/lib/class/hybridauth/index.php(15): Hybrid_Endpoint::process() #3 {main} Next exception 'Exception' with message 'Authentication failed!

The code that is written in the Hybrid/Providers/Facebook.php file is:-
function loginFinish()
{
// in case we get error_reason=user_denied&error=access_denied
if ( isset( $_REQUEST['error'] ) && $_REQUEST['error'] == "access_denied" ){
throw new Exception( "Authentication failed! The user denied your request.", 5 ); //THIS IS LINE NUMBER 86
}
// try to get the UID of the connected user from fb, should be > 0
if ( ! $this->api->getUser() ){
throw new Exception( "Authentication failed! {$this->providerId} returned an invalid user id.", 5 );
}
// set user as logged in
$this->setUserConnected();
// store facebook access token
$this->token( "access_token", $this->api->getAccessToken() );
}
I tried Googling and searching for the issue but I couldn't find anything wrong with this. Sorry I can't provide anything that I got in my research.

Answer 1

This solution works for me:
try{
$hybridauth = new Hybrid_Auth($config);
$adapter = $hybridauth->authenticate($service);
}catch(Exception $ex){
var_dump($ex);
return;
}
$user_profile = $adapter->getUserProfile();
Exception fires Ok.
But if I move line
$hybridauth = new Hybrid_Auth($config);
outside the try{} area then I can't catch this exeption. This is quite wierd because this line works Ok and doesn't throw any exeption.

Answer 2

I had the same problem and solution was that i forgot about namespace (i was operating inside another one), so the correct code for catch block is:
catch(\Exception $e) {}
