Привет, я столкнулся с проблемой, которую не смог найти в сети. Я пытаюсь зайти на свой сайт с помощью входа в Facebook. Это мой код Метод getAccessToken () всегда возвращает ноль. Пожалуйста, помогите мне решить эту ошибку. Спасибо. Ниже мой код.
это мой файл fbConfig.php
<?php
if(!session_id()){
session_start();
}
//Include the autoloader provided in the SDK
require_once 'C:\xampp\htdocs\FBFunApp\php-graph-sdk-5.x\src\Facebook\autoload.php';
//Include required libraries
use Facebook\Facebook;
use Facebook\Exceptions\FacebookResponseException;
use Facebook\Exceptions\FacebookSDKException;
/*
* Configuration and setup Facebook SDK
*/
$appId = '560615054394144'; //Facebook App ID
$appSecret = 'AAAAAAAAAAAAAAAAAAAA'; //Facebook App Secret
$redirectURL = 'http://localhost:8080/FBFunApp/views/login.php'; //Callback URL
$fbPermissions = array('email'); //Optional permissions
$fb = new Facebook(array('app_id' => $appId,'app_secret' => $appSecret,'default_graph_version' => 'v2.10',));
// Get redirect login helper
$helper = $fb->getRedirectLoginHelper();
// Try to get access token
try {
if(isset($_SESSION['facebook_access_token'])){
$accessToken = $_SESSION['facebook_access_token'];
}else{
$accessToken = $helper->getAccessToken();
var_dump($accessToken); //returns null
}
} catch(FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;

Это файл login.php. Файл конфигурации используется внутри.
