我尝试使用carrierwave和fog gems将图像上传到Ruby on Rails上的S3，图像上传正确但是当我尝试保存包含有关刚刚上传的图像信息的模型时，我收到此错误：

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>

用户型号：

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

头像上传者：

# 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

载波初始化器

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

this endpoint.</Message></Error>

这是一个经常遇到的问题：您正在尝试访问区域us-west-1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区域是US Standard，它会自动将请求路由到 Northern 的设施使用网络地图的弗吉尼亚或太平洋西北部（有关详细信息，请参阅区域和端点）。

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/'
  }

再次感谢史蒂芬欧宝！

但是我没有考虑到，我的地区是美国标准，因此，我的载波初始化程序如下所示：# :region => # NOT NEEDED BY US STANDARD :endpoint => ' https://s3.amazonaws.com '
