我正在尝试通过AWS S3托管和提供webfonts(特别是fontawesome)到heroku上的django项目,而且我很难克服可怕的firefox cross-domain font-loading issue。我已经尝试了所有已记录的,已接受的解决方案,但没有一个能为我工作。

我一直看到的推荐解决方案是在我的S3存储桶上编辑CORS配置:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>https://myapp.herokuapp.com</AllowedOrigin>
        <AllowedOrigin>https://www.myapp.herokuapp.com</AllowedOrigin>
        <AllowedOrigin>https://myapp.com</AllowedOrigin>
        <AllowedOrigin>https://www.myapp.com</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>Authorization</AllowedHeader>
   </CORSRule>
</CORSConfiguration>

我尝试过这些设置的不同版本,而firefox仍然在https://www.myapp.com禁止使用HTTP 403:

Request URL: https://my_bucket.s3.amazonaws.com/css/fontawesome-webfont-webfont.ttf
Request Method: GET
Status Code: HTTP/1.1 403 Forbidden

使用该HTTP请求,我在响应头中获得“Access-Control-Allow-Credentials:true”。

还有另一个CORS规则我需要声明firefox接受来自S3的字体吗?当我卷曲字体很棒时,我没有看到任何有助于排除故障的信息:

是否有另一种设置Access-Control-Allow-Origin的方法可以使其正常工作?

答案 0 :(得分:1)

如果要限制对存储桶策略中特定HTTP引用的访问权限,请在引用列表中添加存储桶URL。例如:

SpringConfiguration

检查Firefox中的响应标头。事实证明,referer for font是你的CSS文件,它存放在s3存储桶上,而不是你的域。
