$successCallback public property
PHP callback, which should be triggered in case of successful authentication. This callback should accept yii\authclient\ClientInterface instance as an argument. For example: public function onAuthSuccess($client)
{
$attributes = $client->getUserAttributes();
// user login or signup comes here
}
If this callback returns yii\web\Response instance, it will be used as action response, otherwise redirection to $successUrl will be performed.
