无法在NGINX中提供base64 ttf字体

Question

下面是我的配置，即使它似乎已为ttf字体进行了适当配置，也无法得到投放（文件here, from fullcalendar）

http {
    [...]
    include /etc/nginx/mime.types;
    types {
        application/x-font-ttf ttf;
        font/ttf ttf;
        font/otf otf;
        font/woff woff;
        font/woff2 woff2;
        application/vnd.ms-fontobject eot;
    }

}
