ruby-on-rails - Rails 4:Carrierwave/AWS - Excon::Errors::SocketError/getaddrinfo: nodename 或 servname 提供

Question

想使用 carrierwave gem 和 AWS 从我的应用程序上传图像。但是当我上传图片并提交时出现错误

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

追踪

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#创建

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

但我认为这与我的 aws 设置有关，因为我能够在没有 AWS 的情况下创建图像，但现在由于使用了 fog gem & AWS 访问 & id key ，它不起作用

配置/初始化器.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

在搜索解决方案后，我认为您现在必须添加区域，但这不起作用。

gemfile

Answer 1

您所在的地区应该是“eu-west-1”而不是“爱尔兰”:

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

尽管您应该检查存储桶上的区域以确保您选择了正确的区域。
