Getting a VK token does not work, what could be the problem?

Question

PHP

There is such a file, vk-login.php:

<?php
define('ID', '79*****');
define('SECRET', '9LQ8**************S0');
define('URI', 'https://www.***********.com/admin/comp/vk-login.php');

if(!isset($_GET['code'])) { 
echo 'error';
exit;
}

$ouri = 'https://oauth.vk.com/access_token?client_id='.ID.'&client_secret='.SECRET.'&redirect_uri='.URI.'&code='.$_GET['code'].'&v=5.131';

$token = json_decode(file_get_contents($ouri), TRUE); 
if (!$token) {
    echo 'err';
} else {
    // что-то
}
?>

But during authorization, the token variable is empty, that is, it displays me on the err message.
The application settings themselves seem to be correct, I can even go to https://oauth.vk.com/authorize?client_id= ... and get back to vk-login.php, as I indicated in the login button itself.

<?php echo '<a href="https://oauth.vk.com/authorize?client_id='.ID.'&display=page&redirect_uri='.URI.'&scope=email&response_type=code&v=5.131">Войти</a>';  ?>

I tried other methods of authorization, everywhere there is a problem with the token. What could be the problem?

Answer 1

Because the token does not come in the body. It is in the options after redirecting the authorization page
