設定防盜鏈（Referer）

OSS是按使用收費的服務，為了防止使用者在OSS上的資料被其他人盜鏈，OSS支援基於HTTP header中表頭欄位referer的防盜鏈方法。更多OSS防盜鏈請參考：OSS防盜鏈

設定Referer白名單

通過Bucket#referer=設定Referer白名單：

require 'aliyun/oss'
client = Aliyun::OSS::Client.new(
  endpoint: 'endpoint',
  access_key_id: 'AccessKeyId', access_key_secret: 'AccessKeySecret')
bucket = client.get_bucket('my-bucket')
bucket.referer = BucketReferer.new(
  allow_empty: true, whitelist: ['my-domain.com', '*.example.com'])

bucket = client.get_bucket('my-bucket')
ref = bucket.referer
puts ref.to_s
