Getting a token?

Question

PHP

I can’t find the problem, everything stops to receive the code, we get the code and get a link like: site.ru/sign-vk
?

if(isset($_GET['code'])){

$params = array(
    'client_id'     => $clientId,
    'client_secret' => $clientSecret,
    'code'          => $_GET['code'],
    'redirect_uri'  => $redirectUri
);

$response = json_decode(file_get_contents('https://oauth.vk.com/access_token?'.http_build_query($params)));
 
 
$token = $response -> access_token; // Токен
$expiresIn = $response -> expires_in; // Время жизни токена
$userId = $response -> user_id; // ID  пользователя
$email = $response -> email; // EMAIL пользователя

$_SESSION['vkuid'] = $userId;
$_SESSION['token'] = $token;
$_SESSION['email'] = $email;
}

I solved the problem, but I did not understand where it came from and what it was. Might be useful for someone in the future:

if(isset($_GET['code'])){
  
  $params = array(
    'client_id'     => $clientId,
    'client_secret' => $clientSecret,
    'code'          => $_GET['code'],
    'redirect_uri'  => $redirectUri
);

$content = file_get_contents('https://oauth.vk.com/access_token?' . http_build_query($params));
 
  $response = json_decode($content);
 
 
$token = $response -> access_token; // Токен
$expiresIn = $response -> expires_in; // Время жизни токена
$userId = $response -> user_id; // ID  пользователя
$email = $response -> email; // EMAIL пользователя
 
  
 $_SESSION['vkuid'] = $userId;
$_SESSION['token'] = $token;
$_SESSION['email'] = $email;
 
}
