调用GetBucketLifecycle接口查看存储空间(Bucket)的生命周期规则(Lifecycle)。

注意事项

要查看Bucket的生命周期规则,您必须有oss:GetBucketLifecycle权限。具体操作,请参见为RAM用户授权自定义的权限策略

请求语法

GET /?lifecycle HTTP/1.1
Host: BucketName.oss.aliyuncs.com
Date: GMT Date
Authorization: SignatureValue

当您在OSS ON云盒中调用该接口时,您需要将Host替换为云盒Endpoint。更多信息,请参见云盒Endpoint

示例

请求示例
Get /?lifecycle HTTP/1.1
Host: oss-example.oss.aliyuncs.com  
Date: Mon, 14 Apr 2014 01:17:29 GMT  
Authorization: OSS qn6qrrqxo2oawuk53otfjbyc:ceOEyZavKY4QcjoUWYSpYbJ3****

  • 基于last access time设置生命周期规则的返回示例
    说明 当Bucket存在基于last access time匹配规则的生命周期规则时,返回示例中会包含AtimeBase元素。该元素表示默认last access time的时间戳(从1970-01-01 00:00:00 UTC计算起的秒数),即为Bucket开启访问跟踪时间点的时间戳。
