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