为什么我的Nginx Web服务器不处理ttf字体?

问题描述

我一直在研究由于CORS限制而无法在远程站点上呈现特定字体文件的问题.

I've been researching this issue where a specific font file isn't rendered on remote sites because of CORS restrictions.

到目前为止，我已经能够识别出对该URL的请求正在使用access-control-allow-origin进行响应，但是nginx在远程进行时拒绝了对该字体的请求.

So far I have been able to identify that requests for that url are responding with access-control-allow-origin, but nginx is rejecting requests for that font when made remotely.

我使用的是laravel和spatie的laravel-cors插件，但我不认为这样会返回不是从laravel路线呈现的样式表或字体的标头信息.

I am using laravel and the laravel-cors plugin from spatie, but I wouldn't think that would return header information for a style sheet or font not rendered from laravel routes.

有人知道为什么会这样吗?

Does anyone know why this would happen?

我的错误

Access to font at 'https://example.com/css/widget-icons/icomoon.ttf?wiodlm' from origin 'http://www.second-example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

通过curl检索的标头(似乎允许curl请求)

curl -I https://example.com/css/widget-icons/icomoon.ttf?wiodlm

我的nginx配置为Access-Control-Allow-Origin(已设置为适当的区分大小写).

location ~* .(gif|jpg|jpeg|png|ico|wmv|3gp|avi|mpg|mpeg|mp4|flv|mp3|mid|js|css|wml|swf|ttf|ttc|otf|eot|woff|woff2)$ {
        add_header Access-Control-Allow-Origin "*";
        expires max;
}

添加了模仿类型以通过ttf

application/x-font-ttf           ttc ttf;
application/x-font-otf           otf;
application/font-woff                            woff;
application/font-woff2           woff2;

推荐答案

我通过将用于ttf的mime.types从application/x-font-ttf修改为font/ttf，解决了此问题.

I resolved this issue by modifying the mime.types used for ttf from application/x-font-ttf to font/ttf.

我的Nginx配置

    location ~* .(js|css|ttf|ttc|otf|eot|woff|woff2)$ {
            add_header access-control-allow-origin "*";
            expires max;
    }

mime.types文件

mime.types edit.
    application/x-font-ttf           ttc;
    application/x-font-otf           otf;
    application/font-woff2           woff2;
    font/ttf                         ttf;
