Carrierwave::Qiniu

This gem adds storage support for Qiniu to Carrierwave

example: https://github.com/huobazi/carrierwave-qiniu-example

Installation

Add the following to your application's Gemfile:

gem 'carrierwave-qiniu', '~> 1.1.4'
# If you need to use locales other than English
gem 'carrierwave-i18n'

And then execute:

$ bundle

Or install it yourself as:

$ gem install carrierwave-qiniu -v 1.1.4

Usage

You'll need to configure it in config/initializers/carrierwave.rb

::CarrierWave.configure do |config|
  config.storage              = :qiniu
  config.qiniu_access_key     = "your qiniu access_key"
  config.qiniu_secret_key     = 'your qiniu secret_key'
  config.qiniu_bucket         = "carrierwave-qiniu-example"
  config.qiniu_bucket_domain  = "carrierwave-qiniu-example.aspxboy.com"
  config.qiniu_bucket_private = true #default is false
  config.qiniu_block_size     = 4*1024*1024
  config.qiniu_protocol       = "http"
  config.qiniu_up_host        = 'http://up.qiniug.com' #七牛上传海外服务器,国内使用可以不要这行配置
end

For more information on qiniu, please read http://developer.qiniu.com/docs/v6/

And then in your uploader, set the storage to :qiniu:

class AvatarUploader < CarrierWave::Uploader::Base
  storage :qiniu
end

You can override configuration item in individual uploader like this:

class AvatarUploader < CarrierWave::Uploader::Base
  storage :qiniu

  self.qiniu_bucket                = "avatars"
  self.qiniu_bucket_domain         = "avatars.files.example.com"
  self.qiniu_protocal              = 'http'
  self.qiniu_delete_after_days     = 30
  self.qiniu_can_overwrite         = true
  self.qiniu_bucket_private        = true #default is false
  self.qiniu_callback_url          = "http://<ip1>/callback;http://<ip2>/callback"
  self.qiniu_callback_body         = "key=$(key)&hash=$(etag)&w=$(imageInfo.width)&h=$(imageInfo.height)" # see http://developer.qiniu.com/docs/v6/api/overview/up/response/vars.html#magicvar
  self.qiniu_persistent_notify_url = "http://<ip>/notify"

    # 指定预转数据处理命令
    # https://developer.qiniu.com/kodo/manual/1206/put-policy#2
    def qiniu_persistent_ops
      commands = []

      commands << "avthumb/mp4"
      commands << "avthumb/m3u8/noDomain/1/segtime/15/vb/440k"

      commands
    end

end

You can use qiniu image styles instead version processing of CarrierWave.

# Case 1: Array styles
CarrierWave.configure do |config|
  config.qiniu_styles = [:thumb, :large]
end

class AvatarUploader < CarrierWave::Uploader::Base
  storage :qiniu

  use_qiniu_styles
end

# original url
user.avatar.url

# thumb url
user.avatar.url(:thumb)
# http://.../avatar.jpg-thumb


# Case 2: Hash styles
CarrierWave.configure do |config|
  config.qiniu_styles = { thumb: 'imageView2/1/w/200', large: 'imageView2/1/w/800' }
end

# thumb url
user.avatar.url(:thumb)
# http://.../avatar.jpg-thumb

# inline thubm url
user.avatar.url(:thumb, inline: true)
# http://.../avatar.jpg?imageView2/1/w/200

# just style param
user.avatar.url(style: 'imageView2/1/w/200')
# http://.../avatar.jpg?imageView2/1/w/200

# Case 3: Inline all styles in development environment
CarrierWave.configure do |config|
  config.qiniu_styles = { thumb: 'imageView2/1/w/200', large: 'imageView2/1/w/800' }
  config.qiniu_style_inline = true if Rails.env.development?
end

class AvatarUploader < CarrierWave::Uploader::Base
  storage :qiniu

  use_qiniu_styles
end

user.avatar.url(:thumb)
# http://.../avatar.jpg?imageView2/1/w/200

# Case 4: Custom styles and bucket
class AvatarUploader < CarrierWave::Uploader::Base
  storage :qiniu

  # Override default styles and use your own
  use_qiniu_styles :thumb => 'imageView/0/w/400', :xlarge => 'imageView/0/w/1600'

  self.qiniu_bucket        = "avatars"
  self.qiniu_bucket_domain = "avatars.files.example.com"

end

user.avatar.url(:thumb, inline: true)
# http://.../avatar.jpg?imageView2/1/w/400

Sync Qiniu styles of uploader

$ rake carrierwave:qiniu:sync_styles

# Bucket: bucket_name_1, Set style: thumb => imageView2/1/w/200
# Bucket: bucket_name_2, Set style: large => imageView2/1/w/800
