Aliyun Open Storage Service for Paperclip

This gem implement the support for Aliyun open storage service(OSS) to Paperclip.

Installation

gem install paperclip-storage-aliyun

Or, if you are using a bundler, you can append the following line into your Gemfile:

gem 'paperclip-storage-aliyun'

Configuration

In order to make all the things work, you should do some important configurations through a initializer:

If you are developing a Rails application, you can append a new initializer like:

# [rails_root]/config/initializers/paperclip-aliyun-configuration.rb
Paperclip::Attachment.default_options[:aliyun] = {
  access_id: '3VL9XMho8iCushj8',
  access_key: 'VAUI2q7Tc6yTh1jr3kBsEUzZ84gEa2',
  bucket: 'xx-test',
  data_center: 'cn-hangzhou',
  internal: false,
  protocol: 'https',
  protocol_relative_url: false
}

Then, in the model which defines the attachment, specify your storage and other options, for example:

# [rails_root]/app/models/image.rb
class Image < ActiveRecord::Base
  has_attached_file :attachment, {
    storage: :aliyun,
    styles: { thumbnail: "60x60#"},
    path: 'public/system/:class/:attachment/:id_partition/:style/:filename',
    url: ':aliyun_upload_url'
  }
end

Similar to Paperclip::Storage::S3, there are four options for the url by now:

• :aliyun_upload_url : the url based on the options you give
• :aliyun_internal_url : the internal url, no matter what options[:aliyun][:internal] is
• :aliyun_external_url : the external url, no matter what options[:aliyun][:internal] is
• :aliyun_alias_url : the alias url based on the host_alias you give, typically used together with CDN

Please note the values above are all strings, not symbols. You could still make your own url if only you know what you are doing.

Data Centers

A list of available regions can be found at https://intl.aliyun.com/help/doc-detail/31837.htm. You can use the "Region Expression" column value as it is for the data center, or you can remove the "oss-" prefix. For example: oss-cn-hangzhou and cn-hangzhou are both valid options.

Test

1. Update connection settings in spec/spec_helper.rb:

# Aliyun defaults
OSS_CONNECTION_OPTIONS = {
  access_id: 'your_access_key_id',
  access_key: 'your_access_key_secret',
  bucket: 'your_bucket',
  data_center: 'your_data_center',
  internal: false,
  protocol: 'https'
}

2. Run bundle exec rspec spec.
