ruby-on-rails - 如何从允许 "Access-Control-Allow-Origin"in rails 的公用文件夹提供字体？

Question

我在“公共(public)”文件夹中有字体文件夹。我在 css 文件中使用字体路径，例如:

https://example.com/fonts/icomoon.eot?2p5wfs

我遇到了这个问题:

from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

如果我打开我的 chrome“CORS”扩展程序，它就会工作。如何在不使用此 chrome 扩展程序的情况下加载图标？

Answer 1

尝试:

config.action_dispatch.default_headers = {
    'Access-Control-Allow-Origin' => 'https://example.com',
    'Access-Control-Request-Method' => %w{GET POST OPTIONS}.join(",")
  }
