ruby-on-rails - 使用 s3 和雾上传 Carrierwave

Question

长期以来一直试图搜索此错误的原因，但似乎找不到任何...

所以我有一个 rails 应用程序，我使用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。

最初在开发应用程序时，我允许文件上传在 :file 上，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上线后(我使用 heroku)，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

然后它也为我的应用程序跟踪说明了这一点:

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

还有我的 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，我在 config/initializers 中的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

我实际上对我的fog.rb 中的一些东西感到很困惑。首先，如果我创建了一个名为“ruuva”的存储桶，在我的亚马逊 s3 帐户上使用区域“新加坡”，我应该将我的区域更改为新加坡吗？

感谢任何可以提前提供帮助的人!

Answer 1

首先确保您使用正确的凭据，不要设置自定义区域和自定义目录(在默认区域中免费创建一个假存储桶)

那么我认为您没有为该地区使用正确的名称。尝试像这样设置您的区域:

:region  => 'ap-southeast-1'
