使用asset-sync将资产上传到Amazon S3的Rails应用程序设置,然后在亚马逊上使用CloudFront和CloudFlare作为CDN,我似乎在Chrome中出错访问.svg文件时访问Safari:
此页面包含以下错误:
第1行第1行的错误:编码错误下面是渲染 页面直到第一个错误。
检查标题时,它看起来像这样:

由于Content-Encoding指定了两次,我认为Chrome无法正确解释该文件。
响应看起来像垃圾:

在Firefox中,加载文件并且源看起来很好:

直接从Amazon请求文件只输出这个空的内容编码标题,文件加载正常:
Content-Encoding:
从CloudFront请求时也是如此。似乎 CloudFlare gzips svg文件并根据他们的文档添加content-encoding

将fog-aws gem更新为最新版本后修复此问题:
- fog-aws (0.1.1)
