调用GetBucketLifecycle查看存储空间的生命周期规则

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 qn6q**************:77Dv****************

返回示例

基于last modify time设置生命周期规则的返回示例

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。

SDK

此接口对应的各语言SDK如下：

错误码

错误码	HTTP状态码	描述
AccessDenied	403 Forbidden	没有权限查看Bucket的生命周期规则。只有Bucket的拥有者才能查看Bucket的生命周期规则。
NoSuchBucket或NoSuchLifecycle	404 Not Found	Bucket不存在或没有配置生命周期规则。
