301 S3上传后永久移动

Question

我试图使用carrierwave和雾宝石将图像上传到Ruby on Rails上的S3,正确上传图像但是当我尝试保存包含刚刚上传的图像信息的模型时我得到了这个错误:

Excon::Errors::MovedPermanently in UserController#show
app/models/user.rb:46:in `process_image_with_key'
app/controllers/user_controller.rb:12:in `show'

<Excon::Response:0x007f97846a3c18 @body="<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Error><Code>PermanentRedirect</Code><Message>The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.</Message>

用户模型:

mount_uploader :image, AvatarUploader

def image_name
  File.basename(image.path || image.filename) if image
end

def process_image_with_key( key )
  unless key.nil?
    self.key = key
    self.remote_image_url = self.image.direct_fog_url(with_path: true)
    self.save!
  end
end

AvatarUploader:

# encoding: utf-8

class AvatarUploader < CarrierWave::Uploader::Base

  include CarrierWaveDirect::Uploader

  include CarrierWave::RMagick

  # Include the Sprockets helpers for Rails 3.1+ asset pipeline compatibility:
  include Sprockets::Helpers::RailsHelper
  include Sprockets::Helpers::IsolatedHelper

  include CarrierWave::MimeTypes
  process :set_content_type

  version :thumb do
    process resize_to_fill: [50, 50]
  end

end

用户控制器

def show
  @user = User.find_by_id(params[:id])
  @user.process_image_with_key(params[:key])
  @uploader = User.new.image
  @uploader.success_action_redirect = user_url(@user.id)
end

carriwerwave初始化器

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',
    :aws_access_key_id      => ENV['AWS_ACCESS_KEY_ID'],
    :aws_secret_access_key  => ENV['AWS_SECRET_ACCESS_KEY'],
    :region                 => 'us-west-1'
  }
  config.fog_directory  = ENV['AWS_FILE_BUCKET']
  config.fog_attributes = {'Cache-Control'=>'max-age=315576000'}
end

的Gemfile

gem 'carrierwave'
gem 'rmagick'
gem 'fog'
gem 'carrierwave_direct'

<Error><Code>PermanentRedirect</Code><Message>The bucket you are attempting to access
must be addressed using the specified endpoint. Please send all future requests to 
this endpoint.</Message></Error>

这是一个经常遇到的问题:您正在尝试访问us-west-1区域中的存储桶,但是,由于遗留原因,大多数/所有AWS开发工具包中的默认Amazon S3区域都是美国标准,它会自动将请求路由到Northern的设施弗吉尼亚州或太平洋西北地区使用网络地图(有关详细信息,请参阅地区和终点)

因此,您只需在使用S3 API之前明确指定存储桶区域的端点,例如对于us-west-1:

  config.fog_credentials = {
    :provider               => 'AWS',
    :aws_access_key_id      => ENV['AWS_ACCESS_KEY_ID'],
    :aws_secret_access_key  => ENV['AWS_SECRET_ACCESS_KEY'],
    :region                 => 'us-west-1'
    :endpoint               => 'https://s3-us-west-1.amazonaws.com/'
  }
