Ajax使用带有CORS的JQuery

What is proper way to call Ajax request using JQuery when dealing with CORS?

I use this JavaScript code for ajax call:

        $.ajax({
            type: "GET",
            url: setup.services_domain + "/?type=ajax_cart",
            data: g,
            dataType: "html",
            crossDomain: true,
            headers: {
                  "Access-Control-Allow-Origin":"*"
              },
            xhrFields: { withCredentials: true },
            encode: !0
        }).done(function (a) {

        })

I always get an error:

Access to XMLHttpRequest at 'http://www.services.mysite.sk/?type=ajax_cart&action=add&product_number=462374ML&quantity=1' from origin 'http://www.mysite.sk' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.

Main site is http://www.mysite.sk which is shop, and I have subdomain for all Ajax & API calls http://www.services.mysite.sk called services.

Both for main site and services have set these headers:

 Header set Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
 Header set Access-Control-Allow-Origin "*"
 Header set Access-Control-Allow-Headers "*"

Websites runs on same server with Debian 9 and Apache2 as webserver.

I know that these settings aren't good for production use, but I test it on dev server, and I have problems with these Ajax calls, I just don't know what is wrong with it.
