Rails资产Cloudfront fontawesome CORS [英] Rails assets Cloudfront fontawesome CORS

问题描述

我为此问题尝试了很多在stackoverflow/github上找到的解决方案，但我无法使其正常工作.

I tried a lot of solutions found on stackoverflow/github for this issue but I can't get it to work.

我正在使用 font-awesome-rails ，并且我将自己的资产预编译为生产.我已经在生产配置中为资产设置了CloudFront:

I'm using font-awesome-rails and I precompile my assets for production. I've set CloudFront for my assets in my production config:

config.action_controller.asset_host = "https://XXXX.cloudfront.net"

当我加载页面(从Chrome/Firefox开始，因为Safari可以通过CORS正常运行)时，我收到以下常见错误消息:

When I load a page (from Chrome/Firefox because Safari is OK with CORS) I get this common error message :

Font from origin 'https://XXXX.cloudfront.net' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://example.com' is therefore not allowed access.

我已经尝试过:

I already tried to :

1. 添加 gem rack-cors 和设置服务器标头没有成功
2. 在CloudFront上创建无效失败的三个fontawesome文件

1. Add the gem rack-cors and change my config.ru without success
2. Set an after_filter to set the server headers without success
3. Create an invalidation on CloudFront for the three fontawesome files without success

一种解决方法是删除fontawesome宝石并改为使用:

A workaround would be to remove the fontawesome gem and use instead:

<%= stylesheet_link_tag "//cdnjs.cloudflare.com/ajax/libs/font-awesome/4.4.0/css/font-awesome.min.css", :media => "all" %>

但是我宁愿找到问题.

谢谢

推荐答案

我遇到了这个问题，并通过以下更改解决了该问题.首先，在您的http服务器上设置标头 add_header Access-Control-Allow-Origin *;

I have had this issue and it was solved by doing the following changes. First of all, set a header on your http server add_header Access-Control-Allow-Origin *;

使用的完整配置:

location ~* \.(ttf|ttc|otf|eot|woff|woff2|svg|font.css)$ {
  add_header Access-Control-Allow-Origin *;
  expires max;
  allow all;
  access_log off;
  add_header Cache-Control "public";
}

，然后在Cloudfront上创建失效.

and then create the invalidation on Cloudfront.

ps:我没有使用架芯或其他任何宝石

ps: I did not use rack-cors or any other gem
