PutBucketLifecycle__关于Bucket的操作_API 参考_对象存储 OSS-阿里云

Bucket的拥有者可以通过Put Bucket Lifecycle来设置Bucket的Lifecycle配置。Lifecycle开启后，OSS将按照配置，定期自动删除与Lifecycle规则相匹配的Object。

请求语法

PUT /?lifecycle HTTP/1.1
Date: GMT Date
Content-Length：ContentLength
Content-Type: application/xml
Authorization: SignatureValue 
Host: BucketName.oss.aliyuncs.com
<?xml version="1.0" encoding="UTF-8"?>
<LifecycleConfiguration>
  <Rule>
    <ID>RuleID</ID>
    <Prefix>Prefix</Prefix>
    <Status>Status</Status>
    <Expiration>
      <Days>Days</Days>
    </Expiration>
    <AbortMultipartUpload>
      <Days>Days</Days>
    </AbortMultipartUpload>
  </Rule>
</LifecycleConfiguration>

细节分析

1. 只有Bucket的拥有者才能发起Put Bucket Lifecycle请求，否则返回403 Forbidden消息。错误码：AccessDenied。
2. 如果此前没有设置过Lifecycle，此操作会创建一个新的Lifecycle配置；否则，就覆写先前的配置。
3. 可以对Object设置过期时间，也可以对Part设置过期时间。这里的Part指的是以分片上传方式上传，但最后未提交的分片。
