ruby-on-rails - 雾、Amazon S3 和 Carrierwave Rails 问题

Question

更新内容

我的设置现在如下:

#Carrierwave Initializer

CarrierWave.configure do |config|
    config.fog_credentials = {
        :provider => 'AWS',
        :aws_access_key_id => ENV['S3_KEY'],
        :aws_secret_access_key => ENV['S3_SECRET'], 
    }
    config.fog_directory = ENV['S3_BUCKET_NAME']
    config.fog_public     = false  # optional, defaults to true
    config.fog_attributes = {'Cache-Control'=>'max-age=315576000'}

end


#Uploader

class ProteinUploader < CarrierWave::Uploader::Base
   include CarrierWave::MiniMagick
   storage :fog

   def store_dir
      "images/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
   end

end


#Heroku Config Variables

S3_BUCKET_NAME = top5protein
S3_KEY = 'xxx'
S3_SECRET = 'xxx'


#Gemfile
...
gem "fog", "~> 1.14.0"
gem "excon", "~> 0.25.3"
gem 'carrierwave'
gem 'activeadmin'
...

我仍然遇到的错误是:

如果有人有任何可能有帮助的进一步建议，那就太好了!

Answer 1

在您的情况(如上一条评论中所述)和我的情况下，此错误的原因是 key 不正确。

我想我应该把这个留在这里，以便将来遇到此错误的人可以先检查问题最可能的根源。
