@Nico,

目前还没有woff字体mime类型的定义标准。我使用字体交付cdn服务，它使用字体/woff，我在chrome中得到相同的警告。

WOFF:

网页开放字体格式 它可以用TrueType或PostScript (CFF)概要进行编译 目前FireFox 3.6+支持它

试着补充一下:

AddType application/vnd.ms-fontobject .eot
AddType application/octet-stream .otf .ttf

https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Complete_list_of_MIME_types

这是一个有用的mime类型列表

Mime类型可能不是你唯一的问题。如果字体文件托管在S3或其他域上，您可能还会遇到Firefox无法从不同域加载字体的问题。这在Apache上很容易解决，但在Nginx上，我读到你可能需要用base-64编码你的字体文件，并直接嵌入到你的字体css文件中。

对于所有解决方案index.php删除表单url和woff文件允许。为了在.htaccess文件中编写以下代码，并对应用程序/config/config.php文件进行更改: $config['index_page'] = ";

仅适用于Linux主机服务器。 .htaccess文件详细信息

AddType font/ttf .ttf
AddType font/eot .eot
AddType font/otf .otf
AddType font/woff .woff
<IfModule mod_rewrite.c>

    RewriteBase /

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

截至2017年2月，RFC8081是建议标准。它为字体定义了一个顶级媒体类型，因此WOFF和WOFF2的标准媒体类型如下:

font/woff
font/woff2
