PHP混合Auth与Facebook - Anoying Facebook API错误

Question

我正在尝试Hybrid Auth，但我不知道为什么这不起作用。

我拥有 index.php

中的所有内容

<?php

    use \Psr\Http\Message\ServerRequestInterface as Request;
    use \Psr\Http\Message\ResponseInterface as Response;

    require 'vendor/autoload.php';

    $app = new \Slim\App();

    // facebook api
    define('FACEBOOK_APP_ID','1583449111670664');
    define('FACEBOOK_APP_KEY','c673d4ec188b72d00a31388d2d31bfdc');

    $container = $app->getContainer();
    $container['hybrid-api'] = function($c) {
        $settings = [

            'base_url' => 'http://localhost/hybrid-auth/auth', 

            'providers' => [ 
                'Facebook' => [ 
                    'enabled' => true,
                    'keys'    => ['id' => FACEBOOK_APP_ID, 'secret' => FACEBOOK_APP_KEY],
                    'scope'   => ['id','name','first_name','last_name','link','locale','email'], 
                    'trustForwarded' => true
                ]
            ],
            'debug_mode' => 'info',
            'debug_file' => 'logs/hybrid-auth.log',
        ];

        return new Hybrid_Auth($settings);
    };

    $app->get('/', function(Request $request, Response $response){ 
        $hybrid = $this->get('hybrid-api');
        $session_user = Hybrid_Auth::storage()->get('user');

        if( empty($session_user) ) {
            echo "<a href='/hybrid-auth/login'>login</a>";
        } else {
            echo "Welcome " . $session_user->displayName . "<br />";
        }
    });

    $app->get('/login', function(Request $request, Response $response){
        $hybrid = $this->get('hybrid-api');
        $adapter = $hybrid->authenticate(ucwords('facebook'));
        $user_profile = $adapter->getUserProfile();

        if( empty( $user_profile ) ) {
            echo 'Error!!'; 
        } else {
            Hybrid_Auth::storage()->set('user', $user_profile);   
            return $response->withRedirect('/hybrid-auth'); 
        }
    });

    $app->get('/auth', function(Request $request, Response $response){
        Hybrid_Endpoint::process();
    });

    $app->run();

composer.json

"require": {
    "slim/slim": "^3.0",
    "hybridauth/hybridauth": "2.8.2"
}

我正在apache2上运行它作为文件夹。 http://localhost/hybrid-auth

我不会提取Facebook应用程序ID和密钥，因为它是一个测试应用程序。

错误

在Hybrid Auth日志中，一切正常。没有错误消息。
