所以我有一个rails应用程序,我利用carrierwave上传图片.我还想在我的应用程序中使用Amazon S3进行文件上传存储.

最初,当我开发应用程序时,我允许文件上传到on：文件,即

image_uploader.rb

# Choose what kind of storage to use for this uploader:
  storage :file
# storage :fog

现在,在完成开发并将其置于实时(我使用heroku)之后,我决定将载波存储更改为S3以在本地进行测试.

image_uploader.rb

# Choose what kind of storage to use for this uploader:
# storage :file
storage :fog

但是,现在当我尝试上传图片(无论是用户头像等)时,我收到此错误：

Excon::Errors::Forbidden in UsersController#update

然后它也说明了我的应用程序跟踪：

app/controllers/users_controller.rb:39:in `update'

我的REQUEST参数：

{"utf8"=>"✓","_method"=>"put","authenticity_token"=>"DvADD1vYpCLcghq+EIOwVSjsfmAWCHhtA3VI5VGD/q8=","user"=>{"avatar"=>#<ActionDispatch::Http::UploadedFile:0x007fc88cde76f8     
@original_filename="JeffPortraitMedium.png",@content_type="image/png",@headers="Content-Disposition: form-data; name=\"user[avatar]\";   
filename=\"JeffPortraitMedium.png\"\r\nContent-Type: image/png\r\n",@tempfile=#<File:/var/folders/vg/98nv58ss4v7gcbf8px_8dyqc0000gq/T/RackMultipart20120226- 19096-1ppu2sr>>,"remote_avatar_url"=>"","name"=>"Jeff Lam ","email"=>"email@gmail.com","user_bio"=>"Tester Hello","shop"=>"1"},"commit"=>"Update Changes","id"=>"1"}

这是我的users_controller.rb部分代码：

def update
    @user = User.find(params[:id])
    if @user.update_attributes(params[:user]) 
        redirect_back_or root_path
        flash[:success] = "Your have updated your settings successfully."
    else
        flash.now[:error] = "Sorry! We are unable to update your settings. Please check your fields and try again."
        render 'edit'
    end
end

我的image_uploader.rb代码

# encoding: utf-8
class ImageUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  # storage :file
  storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url
  #   "/images/fallback/" + [version_name,"default.png"].compact.join('_')
  # end

  # Process files as they are uploaded:
  # process :scale => [200,300]
  #
  # def scale(width,height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  version :thumb do
    process resize_to_fill: [360,250]
  end

  version :cover_photo_thumb do
    process resize_to_fill: [1170,400]
  end

  version :event do
    process resize_to_fill: [550,382]
  end

  version :product do
    process resize_to_fit: [226,316]
  end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_white_list
    %w(jpg jpeg gif png)
  end

  # Override the filename of the uploaded files:
  # Avoid using model.id or version_name here,see uploader/store.rb for details.
  # def filename
  #   "something.jpg" if original_filename
  # end 

  # fix for Heroku,unfortunately,it disables caching,# see: https://github.com/jnicklas/carrierwave/wiki/How-to%3A-Make-Carrierwave-work-on-Heroku
  def cache_dir
    "#{Rails.root}/tmp/uploads"
  end

end

最后,在config / initializers中我的fog.rb文件

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',# required
    :aws_access_key_id      => 'ACCESS_KEY',# required
    :aws_secret_access_key  => 'SECRET_ACCESS_KEY/ZN5SkOUtOEHd61/Cglq9',# required
    :region                 => 'Singapore'  # optional,defaults to 'us-east-1' 
  }
  config.fog_directory  = 'ruuva/'                     # required
  config.fog_public     = false                          # optional,defaults to true
end

我真的很困惑我的雾中的一些东西.rb.首先,如果我在我的亚马逊s3账户上创建一个名为“ruuva”的区域“新加坡”,我应该将我的区域更改为新加坡吗？

感谢任何可以提前帮助的人！
