Nginx cross-domain access to fonts

Today suddenly encountered a problem, the site with the primary domain name, and then its resource file is also configured with a res two domain name, resulting in CSS style reference font style error

Cross-origin requests have been intercepted: the same origin policy prohibits reading remote resources located in http://res.******/fontawesome-webfont.woff2?v=4.5.0. (Reason: CORS header is missing ' Access-control-allow-origin ').

workaround, in res level two domain name nginx.conf plus

Location ~* \. (EOT|TTF|WOFF|SVG|OTF) $ {
Add_header Access-control-allow-origin * or domain name;
Add_header access-control-allow-headers X-requested-with;
Add_header Access-control-allow-methods get,post,options;
}
