Java存储空间清单

本文介绍如何添加、查看、批量列举和删除存储空间(Bucket)的清单(Inventory)配置。

注意事项

  • 本文以华东1(杭州)外网Endpoint为例。如果您希望通过与OSS同地域的其他阿里云产品访问OSS,请使用内网Endpoint。关于OSS支持的Region与Endpoint的对应关系,请参见OSS访问域名、数据中心、开放端口

  • 本文以从环境变量读取访问凭证为例。如何配置访问凭证,请参见Java配置访问凭证

  • 本文以OSS域名新建OSSClient为例。如果您希望通过自定义域名、STS等方式新建OSSClient,请参见新建OSSClient

  • 请确保您拥有调用添加、查看、列举和删除存储空间清单配置的权限。Bucket所有者默认拥有此类权限,如果您无此类权限,请先向Bucket所有者申请对应操作的权限。

  • 单个Bucket最多只能有1000条清单配置。

  • 配置清单的源Bucket与存放导出的清单文件所在的目标Bucket必须位于同一个Region。

添加清单配置

以下代码用于为某个Bucket添加清单配置:

批量列举清单配置

说明

单次请求最多可获取100条清单配置项内容。若需获取超过100条清单配置项,则需发送多次请求,并保留相应的Token,作为下一次请求的参数。

以下代码用于批量列举某个Bucket的清单配置:
