header('Content-Type: application/json');
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET');
header("Access-Control-Allow-Headers: X-Requested-With");

but I still have the anserw :

" Access to XMLHttpRequest at 'http://localhost/spring_box/api.php' from origin 'http://localhost:52502' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' "

Can you help me to solve my problem please?
