Question

有奇怪的问题，无法理解有什么问题。所有作品都提交给了heroku。我试图在s3服务器上存储回形针附件。但无法使其在生产和开发上发挥作用。

game.rb ：

has_attached_file :image,
                :styles => { :big => "500x500",
                             :tiny => "25x25" },
                :default_url => "/images/game/:style/missing.png",
                :storage => :s3,
                :s3_credentials => S3_CREDENTIALS,
                :path => "games/:id/:style.:extension",
                :bucket => 'my-assets'

validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/
validates_attachment_file_name :image, :matches => [/png\Z/, /jpe?g\Z/]

config / initializers / s3.rb文件：

if Rails.env == "production"
  # set credentials from ENV hash
  S3_CREDENTIALS = { :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
                     :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'],
                     :bucket => "my-assets" }
else
  # get credentials from YML file
  S3_CREDENTIALS = Rails.root.join("config/s3.yml")
end

配置/ s3.yml

development:
  access_key_id: XXX
  secret_access_key: YYY
  bucket: my-assets

production:
  access_key_id: XXX
  secret_access_key: YYY
  bucket: my-assets

尝试提交后我得到了空白页面，服务器日志告诉我：

尝试测试开发（本地）时，服务器错误有点不同：

[paperclip] saving /games/images/000/000/001/original/game.png
   (0.4ms)  ROLLBACK
Completed 500 Internal Server Error in 1210ms

    Errno::ECONNREFUSED (Connection refused - connect(2) for "my-assets.my-assets.s3-website-us-east-1.amazonaws.com" port 443):

转到S3控制台并确保将存储桶设置为＆＃34;不要启用网站托管＆＃34;在＆＃34;静态网站托管＆＃34;。

我建议您仅将s3凭据存储在ENV变量中并转储s3.yml文件。它更安全。

您可以在环境文件（production.rb，development.rb，test.rb等）中设置回形针默认值，如下所示：

  config.paperclip_defaults = {
    :storage => :s3,
    :s3_credentials => {
      :bucket => ENV['AWSBucketName'],
      :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
      :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
  }

你不需要在你的模型中重复那些（game.rb）
