对象存储 OSS设置CORS规则

详细解答可以参考官方帮助文档

通过Bucket#cors=设置CORS规则：

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.cors = [
    CORSRule.new(
      :allowed_origins => ['aliyun.com', 'http://www.taobao.com'],
      :allowed_methods => ['PUT', 'POST', 'GET'],
      :allowed_headers => ['Authorization'],
      :expose_headers => ['x-oss-test'],
      :max_age_seconds => 100)
]
