Carrierwave上傳與S3和霧

Question

一直試圖尋找這個錯誤很長一段時間的原因，似乎無法找到任何...

所以我有一個Rails應用程序，我使用的圖片carrierwave上傳。我也想在我的應用中使用Amazon S3進行文件上傳存儲。

最初爲我開發我允許上傳文件要上的應用：文件，即

image_uploader.rb

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

現在在完成了開發，並把它活（我用heroku），我決定將carrierwave存儲改爲S3以在本地進行測試。

image_uploader.rb

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

不過，現在當我嘗試上傳圖片（可以是用戶的頭像等），我得到這個錯誤：

Excon::Errors::Forbidden in UsersController#update

，然後它說這個以及我的應用程序跟蹤：

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

，我有所求參數：

{"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"} 

這裏是我的users_controller.rb部分代碼：

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image_uploader.rb代碼

# 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 

最後，在配置我fog.rb文件/初始化

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 

我對fog.rb中的一些東西其實很困惑。首先，如果我在亞馬遜S3帳戶上創建了一個名爲「ruuva」的桶，並在該地區添加了「新加坡」，我應該將該地區更改爲新加坡嗎？

謝謝任何​​能夠提前幫助的人！

Answer 1

首先確保你通過不設置自定義區域，並自定義目錄使用權證書（在默認區域免費創建一個假桶）

那麼我想你是不是該地區使用正確的名稱。嘗試設置你的區域是這樣的：

:region => 'ap-southeast-1' 

Answer 2

我們面臨同樣的問題，修好了相關變更您訪問密鑰的用戶的許可，將其更改爲「高級用戶」。在投入生產之前，請檢查您是否需要用戶成爲超級用戶。
