You can’t get Authorization header in Apache server:
$request->getHeader("Authorization")
You can get this header with this method:
$headers = apache_request_headers(); $headers["Authorization"];
But when you use oauth2-client you can’t use that method.
You must use .htaccess file:
RewriteEngine On RewriteCond %{HTTP:Authorization} ^(.+) RewriteRule . - [e=HTTP_AUTHORIZATION:%1]
