#aliyun_accesskey_id ⇒ Object (readonly)

Initialize connection to OSS

Notes

options parameter must include values for :aliyun_accesskey_id, :aliyun_secret_access_key and :aliyun_oss_bucket in order to create a connection. :aliyun_oss_location will be replaced by :aliyun_region_id, and it has a default value cn-hangzhou if :aliyun_oss_endpoint is not specified, it will be generated by method region_to_endpoint

Examples

sdb = Fog::Storage.new(:provider=>'aliyun',
 :aliyun_accesskey_id => your_:aliyun_accesskey_id,
 :aliyun_secret_access_key => your_aliyun_secret_access_key
)

Parameters

  • options<~Hash> - config arguments for connection. Defaults to {}.

Returns

  • OSS object with connection to aliyun.
