Carrierwave和亚马逊s3

Question

我正在使用carrierwave gem来管理我的rails 3 app中的文件上传,但是,我无法连接到我的amazon s3存储桶.

我已按照维基上的说明进行操作,但它们不够详细,例如我在哪里存储我的s3凭据？

Answer 1

把这样的东西放在初始化器中.

CarrierWave.configure do |config|
  config.storage = :fog
  config.fog_directory = 'your_bucket'

  config.fog_credentials = {
    :provider => 'AWS',
    :aws_access_key_id => 'your_access_key'
    :aws_secret_access_key => 'your_secret_key',
    :region => 'your_region'
  }
end

如果需要,您可以将凭据存储在文件中(并且代码是私有的).或者从单独的文件或数据库,由您决定.以下将加载配置文件并允许基于env的不同配置.

# some module in your app
module YourApp::AWS
  CONFIG_PATH = File.join(Rails.root, 'config/aws.yml')

  def self.config
    @_config ||= YAML.load_file(CONFIG_PATH)[Rails.env]
  end
end

# config/aws.yml
base: &base
  secret_access_key: "your_secret_access_key"
  access_key_id: "your_access_key_id"
  region: your_region
development:
  <<: *base
  bucket_name: your_dev_bucket
production:
  <<: *base
  bucket_name: your_production_bucket

# back in the initializer
config.fog_directory = YourApp::AWS.config['bucket_name']
# ...
config.fog_credentials = {
  :provider => 'AWS',
  :aws_access_key_id => YourApp::AWS.config['access_key_id'],
  :aws_secret_access_key => YourApp::AWS.config['secret_access_key'],
  :region => YourApp::AWS.config['region']
}
