ajax发布到php返回$ _SERVER ['REQUEST_METHOD'] GET

Question

I'm trying to post newsletter form data to a php page with ajax but when I echo $_SERVER['REQUEST_METHOD'] on the php page it prints GET(with no variables). I have used similar code on multiple websites with no problems. (jquery v3.2.1)

  $.ajax({
            method: 'post', 
            dataType: 'json',
            url: '<?=$site_url?>/templates/xxxx/contact_send/email_send.php',
            data: JSON.stringify(dataString),
            contentType: 'application/JSON;charset=UTF-8',
            success: function () {
                console.log('success');
            }
        });
