ruby-on-rails - Carrierwave+fog+s3 不适用于 Cloud Front URL

Question

我遇到了这个问题 carrierwave+fog+s3与亚马逊 cloud front .通过以下设置，我可以将文件上传到 s3，但上传后，我从 Rails 应用程序获取的 S3 对象 URL 没有 assets_host基于 URL，即我希望 URL 看起来像这种格式 https://mycloudfrontname.cloudfront.net/uploads/myfile.mp3
但它们都以这种格式出现https://mybucketname.s3.amazonaws.com/uploads/myfile.mp3
这里可能有什么问题？

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',
    :aws_access_key_id      => 'XXXX',
    :aws_secret_access_key  => 'XXXX',
    :region                 => 'us-east-1'
  }
  config.fog_directory  = 'mybucketname'
  config.asset_host     = 'https://mycloudfrontname.cloudfront.net'
  config.fog_public     = false
  config.fog_attributes = {'Cache-Control' => 'max-age=315576000'}
end

更新:

我从 Carrierwave 的 /lib/carrierwave/storage/fog.rb 中找到了这个代码位- 所以如果我们设置 asset_host就像上面的代码片段一样，这一定能正常工作吗？或者我还必须做任何其他配置吗？

def public_url
          if host = @uploader.asset_host
            if host.respond_to? :call
              "#{host.call(self)}/#{path}"
            else
              "#{host}/#{path}"
            end
          else
            # AWS/Google optimized for speed over correctness
            case @uploader.fog_credentials[:provider]
            when 'AWS'
              # if directory is a valid subdomain, use that style for access
              if @uploader.fog_directory.to_s =~ /^(?:[a-z]|\d(?!\d{0,2}(?:\d{1,3}){3}$))(?:[a-z0-9\.]|(?![\-])|\-(?![\.])){1,61}[a-z0-9]$/
                "https://#{@uploader.fog_directory}.s3.amazonaws.com/#{path}"
              else
                # directory is not a valid subdomain, so use path style for access
                "https://s3.amazonaws.com/#{@uploader.fog_directory}/#{path}"
              end
            when 'Google'
              "https://commondatastorage.googleapis.com/#{@uploader.fog_directory}/#{path}"
            else
              # avoid a get by just using local reference
              directory.files.new(:key => path).public_url
            end
          end
        end

更改 config.fog_public至 true并添加 config.asset_host = 'YOUR_CND_ADDRESS' . asset_host fog_public 时不起作用是假的
