Rails 4：Carrierwave/AWS - Excon :: Errors :: SocketError/getaddrinfo：提供的節點名稱和服務名稱

Question

想要使用carrierwave gem和AWS從我的應用上傳圖像。 但是當我上傳的圖片，並提交得到錯誤

Excon::Errors::SocketError in MoviesController#create 
getaddrinfo: nodename nor servname provided 

跟蹤

app/controllers/movies_controller.rb:30:in `block in create' 
app/controllers/movies_controller.rb:29:in `create' 

Parameters: 

{"utf8"=>"✓", 
"authenticity_token"=>"laitXtzkMnWd/EHtVjFx0X5vE0P4kowXu84wH8fEVOQ=", 
"movie"=>{"title"=>"new ", 
"description"=>"te", 
"movie_length"=>"12", 
"director"=>"12", 
"rating"=>"12", 
"image"=>#<ActionDispatch::Http::UploadedFile:0x007fc913845fb0 @tempfile=#<Tempfile:/var/folders/s8/fd5_m1_d3436ptj9znpcy3cc0000gn/T/RackMultipart20150211-642-1ow2dmn>, 
@original_filename="IMG_0892.JPG", 
@content_type="image/jpeg", 
@headers="Content-Disposition: form-data; name=\"movie[image]\"; filename=\"IMG_0892.JPG\"\r\nContent-Type: image/jpeg\r\n">}, 
"commit"=>"Create Movie"} 

MoviesController＃創建

def create 
@movie = Movie.new(movie_params) 

respond_to do |format| 
    **if @movie.save**<--- Error 
    format.html { redirect_to @movie, notice: 'Movie was successfully created.' } 
    format.json { render :show, status: :created, location: @movie } 
    else 
    format.html { render :new } 
    format.json { render json: @movie.errors, status: :unprocessable_entity } 
    end 

，但我認爲它是與我的AWS設置，因爲我是能夠在沒有AWS的情況下創建圖像，但現在自使用霧寶石& AWS訪問& ID鍵它不起作用

配置/ initialiser.rb

CarrierWave.configure do |config| 
    config.fog_credentials = { 
    :provider    => 'AWS',      # required 
    :aws_access_key_id  => 'AKIAIxxxxxxA',      # required 
    :aws_secret_access_key => 'UdRxhdOHoaxxxxxxxx3I9+vIId+', 
    :region => 'Ireland',      # required 
    } 
    config.fog_directory = 'moviesdemo'      # required 
end 

尋找解決的辦法，我相信你現在已經添加的區域，但是這是行不通的。

Answer 1

你的區域應該是這樣的 「歐盟 - 西-1」 而不是 「愛爾蘭」：

:region => 'eu-west-1',      

雖然你應該檢查你的區域在你的水桶，以確保你正在選擇正確的。
