这是我的配置文件app / config / initializers / carrierwave.rb

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',# required
    :aws_access_key_id      => 'AKIAJKOHTE4WTXCCXAMA',# required
    :aws_secret_access_key  => 'some secret key here',# required
    :region                 => 'eu-east-1',# optional,defaults to 'us-east-1'
    :host                   => 'https://s3.amazonaws.com',defaults to nil
    :endpoint               => 'https://s3.amazonaws.com:8080'              # optional,defaults to nil
  }
  config.fog_directory  = 'createmysite.co.za'                    # required
  config.fog_public     = false                                   # optional,defaults to true
  #config.fog_attributes = {'Cache-Control'=>'max-age=315576000'} # optional,defaults to {}
end

这是网址看起来像应该显示的图像

<img alt="Normal_selection_003" src="https://createmysite.co.za.s3.amazonaws.com/uploads/portfolio/image/3/normal_Selection_003.png?AWSAccessKeyId=AKIAJKOHTE4WTXCCXAMA&amp;Signature=8PLq8WCkfrkthmfVGfXX9K6s5fc%3D&amp;Expires=1354859553">

当我打开图像url这是从亚马逊的输出

更新

新配置文件(添加了雾url到期)app / config / initializers / carrierwave.rb

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',# required
    :aws_secret_access_key  => 'chuck norris',# required
  }
  config.fog_directory  = 'createmysite.co.za'                              # required
  config.fog_public     = false                                             # optional,defaults to true
  config.fog_authenticated_url_expiration = 600                             # (in seconds) => 10 minutes
end
