Question

我知道还有其他问题是相同的，但它们没有解决我的问题。

我一直收到错误：Aws::Errors::MissingRegionError in BooksController#create，

missing region; use :region option or export region name to ENV['AWS_REGION']。但是，这是我在

中的配置

Development.rb：

config.paperclip_defaults = {
        storage: :s3,
        s3_host_name: "s3-us-west-2.amazonaws.com",
        s3_credentials: {
            bucket: ENV['AWS_BUCKET'],
            access_key_id: ENV['AWS_ACCESS_KEY_ID'],
            secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
            s3_region: ENV['us-west-2']
        }

    }

Production.rb：

config.paperclip_defaults = {
        storage: :s3,
        s3_host_name: "s3-us-west-2.amazonaws.com",
        s3_credentials: {
            bucket: ENV['AWS_BUCKET'],
            access_key_id: ENV['AWS_ACCESS_KEY_ID'],
            secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
            s3_region: ENV['us-west-2']
        }

    }

和Application.rb：

config.paperclip_defaults = {
        storage: :s3,
        s3_host_name: "s3-us-west-2.amazonaws.com",
        s3_credentials: {
            bucket: ENV['AWS_BUCKET'],
            access_key_id: ENV['AWS_ACCESS_KEY_ID'],
            secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
            s3_region: ENV['us-west-2']
        }

    }

然而，它不断出现错误。我从其他问题中听取了其他人的建议。希望有人可以提供帮助。

Answer 1

您应该将ENV['AWS_REGION'] env变量设置为"us-west-2"并将其用作

s3_region: ENV['AWS_REGION']

或使用字符串：

s3_region: 'us-west-2'

另外，s3_region选项应该移出credentials中的config/environments/{development|production}哈希：

config.paperclip_defaults = {
  storage: :s3,
  s3_host_name: "s3-us-west-2.amazonaws.com",
  s3_region: 'us-west-2', # or ENV['AWS_REGION']
  s3_credentials: {
    bucket: ENV['AWS_BUCKET'],
    access_key_id: ENV['AWS_ACCESS_KEY_ID'],
    secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
  }
}

Answer 2

Rails 5 Way：

根据更新的文档区域是必要的。非us-region所需的地方。使用paperclip设置s3的推荐方法是：

将您的秘密信息放在yml文件中，让我们说aws.yml（必须是git 忽略）
将您的全局配置放在环境文件中，即 development/production.rb

config/environments/

将您的文件相关设置放入模型中。就我而言，我正在定义 User模型

示例步骤1：（config/aws.yml）

development:
  access_key_id: AWS_ACCESS_KEY_ID # without quotation marks
  secret_access_key: AWS_SECRET_KEY_ID # without quotation marks

production:
  access_key_id: <%= ENV["AWS_ACCESS_KEY_ID"] %> # get it from terminal environment
  secret_access_key: <%= ENV["AWS_SECRET_KEY_ID"] %> # get it from terminal environment

示例步骤2：（config/environments/development.rb）

# US West (N. California)  us-west-2   apigateway.us-west-2.amazonaws.com  HTTPS

config.paperclip_defaults = {
  :storage => :s3,
  :s3_region => 'us-west-2',
  :bucket => 'production-bucket',
  :path => '/:class/:attachment/:id_partition/:style/:filename',
  :s3_credentials => "#{Rails.root}/config/aws.yml",
}

示例步骤3：（app/models/user.rb）

has_attached_file :avatar, styles: { medium: "300x300>", thumb: "100x100>" }
validates_attachment_content_type :avatar, content_type: /\Aimage\/.*\z/

最后您可以上传文件：

def upload_to_s3
    response = {JSON_KEY_STATUS_MESSAGE: "OK", server_time: DateTime.current.to_i}
    response[:user] = []
    response[:status] = '0'

    unless params[:avatar].present?
        response[:message] = 'either user avatar image file [avatar]'
        render json: response and return
    end

    begin
        user = User.new # create new user
        user.avatar = params[:avatar] # params[:avatar] is a file posted by form in mutli-part true over json api
        s = user.save # save it # will through error if you have more than one required attributes
        if(s != false)
            response[:message] = 'file Successfully upload to s3'
        else
            response[:message] = 'fail to upload file to s3'
        end
    rescue => e
        response[:message] = e.message # this guy will help debug a lot!
    end
    render json: response and return
end

Answer 3

创建一个名为：

的文件

config/initializers/paperclip.rb

并添加以下内容：

Paperclip::Attachment.default_options[:url] = ':s3_domain_url'
Paperclip::Attachment.default_options[:path] = '/:class/:attachment/:id_partition/:style/:filename'
Paperclip::Attachment.default_options[:s3_host_name] = 's3-eu-west-1.amazonaws.com'

在第3行，我有eu-west-1取代你所在的地区。

失踪地区;使用：区域选项或导出区域名称到ENV ['AWS_REGION']
