我正在使用Rails + Carrierwave上传图像，这些图像存储在S3上并通过Cloudfront CDN提供服务。网站上的所有图像都可以毫无问题地提供，但是在实施Ckeditor（gem）之后，我对通过Ckeditor上传的图像一直遇到问题。它们已正确上载到S3，并最初显示，但过了一段时间就会过期。 This is the expiry message when I access the image src after it has expired
我已经搜索了Stack Overflow，但没有找到与该主题相关的答案。我了解这是因为Ckeditor将预签名的URL发送到S3，并且这些预签名的URL指定了到期时间。我尝试将config.fog_public = true设置为无效（路由问题和图像无法上传），并且尝试将S3仪表板中的ckeditor文件夹设为公开，这也是行不通的。
有什么方法可以使config.fog_public = true对我的Ckeditor上传有效，或者是否有其他方法可以确保Ckeditor发送到S3的预签名URL不会过期？
我尝试过的事情：
这是我的上传者> ckeditor_picture_uploader.rb文件
require 'carrierwave'
class CkeditorPictureUploader < CarrierWave::Uploader::Base
include Ckeditor::Backend::CarrierWave
include CarrierWave::MiniMagick
if Rails.env.production?
storage :fog
else
storage :file
end
def cache_dir
"#{Rails.root}/tmp/uploads"
end
def store_dir
"uploads/ckeditor/pictures/#{model.id}"
end
process :extract_dimensions
version :thumb do
process resize_to_fill: [118, 100]
end
version :content do
process resize_to_limit: [800, 800]
end
def extension_white_list
Ckeditor.image_file_types
end
configure do |c|
c.fog_public = true
end
end
However, this results in there being a routing error and Ckeditor no longer shows the image
This is the routing error in my logs.
