我使用nginx作为我的主机，使用Amazon Cloudfront作为我的cdn。
我的cdn标题将Access-Control-Allow-Origin设置为*
从我的网站：
curl -I http://example.com/ThemeIcons.woff?387osh
HTTP/1.1 200 OK
Server: nginx

但Chrome控制台中的消息仍然显示，
Access to Font at

has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'http://example.com' is therefore not allowed access.
我已经研究了2天了，有人可以帮我吗？谢谢！
