Paperclip 缺少与 Amazon S3 的协议 (https)

Paperclip is missing the Protocol (https) with Amazon S3

在production.rb中:

config.paperclip_defaults = {
    s3_host_name: "s3.#{ENV.fetch('AWS_REGION')}.amazonaws.com",
    storage: :s3,
    s3_credentials: {
        bucket: ENV.fetch('S3_BUCKET_NAME'),
        access_key_id: ENV.fetch('AWS_ACCESS_KEY_ID'),
        secret_access_key: ENV.fetch('AWS_SECRET_ACCESS_KEY'),
        s3_region: ENV.fetch('AWS_REGION'),
    }
}

我在 initializers/paperclip.rb.

中没有任何内容

在我的模型中:

class MyModel < ApplicationRecord
  has_attached_file :photo, styles: {
      thumb: '100x100>',
      square: '200x200#',
      medium: '300x300>'
  }
  validates_attachment_content_type :photo, content_type: /\Aimage\/.*\Z/
  def photo_url=(url)
    self.photo = URI.parse(url)
  end
end

然后我测试一下:

m = Model.new
m.photo_url = "https://s3.us-east-2.amazonaws.com/mybucket/sports-grill-miami.jpg"
m.save!
m.photo.url(:thumb)
"//s3.us-east-2.amazonaws.com/mybucket/buckets/photos/000/000/005/thumb/sports-grill-miami.jpg?1495237443" 

为什么缺少 HTTPS 协议?这使我的 android 应用程序崩溃,因为它需要一个协议才能连接到 URL。我需要硬编码 URL 或者 Paperclip 可以处理这个吗?

您需要明确地将协议添加到您的配置中:

:s3_protocol => :https

您需要在 paperclip 配置上指定方案,如下所示:

config.paperclip_defaults = {
      s3_host_name: "s3.#{ENV.fetch('AWS_REGION')}.amazonaws.com",
      storage: :s3,
      :s3_protocol => :https, # <- added this
      s3_credentials: {
          bucket: ENV.fetch('S3_BUCKET_NAME'),
          access_key_id: ENV.fetch('AWS_ACCESS_KEY_ID'),
          secret_access_key: ENV.fetch('AWS_SECRET_ACCESS_KEY'),
          s3_region: ENV.fetch('AWS_REGION'),
      }
  }

:s3_protocol => :https 会将方案 https 分配给为您的亚马逊 s3 资产生成的 url。详情请参阅 documentation
