下面代碼直接複製即用，寫在公共層，所有頁面繼承。意思自己查
header('Access-Control-Allow-Origin: ' . (isset($_SERVER['HTTP_ORIGIN']) ? $_SERVER['HTTP_ORIGIN'] : '*'));
header('Access-Control-Allow-Methods: GET, POST, PUT, PATCH, DELETE, OPTIONS');
header('Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept');
if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
    exit;
}
