一、Nginx服务器解决方法

服务器使用的是 Nginx，要在响应的头部添加 Access-Control-Allow-Origin 字段，添加方法是用 add_header 指令：

配置例子:

复制代码 代码如下:
location /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
    add_header Access-Control-Allow-Origin *;
}

二、Apache服务器解决方法

Font Awesome (firefox无法显示 火狐无法显示)Cross domain (跨域问题) 

The problem

It seems that, for security reasons, Firefox simply don't allow you to use by default a font that is not hosted on your domain, not even on your subdomain. The CDN based websites can be also affected in this case.

The solution

After some investigations, I found out the workaround: set a Access-Control-Allow-Origin header to the font.
复制代码 代码如下:
<FilesMatch "\.(ttf|otf|eot|woff)$">
  <IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
  </IfModule>
</FilesMatch>

Also, if you are using nginx as your webserver you will need to include the code below in your virtual host file:
复制代码 代码如下:
location ~* \.(eot|otf|ttf|woff)$ {
    add_header Access-Control-Allow-Origin *;
}
