Firefox WebFont 403尽管有S3 CORS规则

Question

我正在尝试从AWS S3托管和提供webfonts(特别是fontawesome)到heroku上的django项目,我很难克服可怕的firefox跨域字体加载问题.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>

我已经尝试了这些设置的不同变体,firefox仍然从https://www.myapp.com禁止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".

是否有另一个CORS规则我需要声明firefox接受来自S3的字体？当我卷曲字体 - 真棒我没有/看到任何有用的故障排除:

有没有其他方法来设置可能使这个工作的Access-Control-Allow-Origin？

Answer 1

如果您在存储桶策略中限制对特定 HTTP 引荐来源网址的访问，请将您的存储桶 URL 也添加到引荐来源网址列表中。例如：

"Condition": {
    "StringLike": {
        "aws:Referer": [
            "http://my_bucket.s3.amazonaws.com/*",
            "https://my_bucket.s3.amazonaws.com/*",
            "http://www.example.com/*",
            "https://www.example.com/*",
        ]
    }
}

检查 Firefox 中的响应标头。事实证明，字体的引用是您的 CSS 文件，该文件托管在 s3 存储桶上，而不是您的域。
