删除 Amazon S3 on Outposts 存储桶中的对象

以下示例使用 AWS CLI 从 S3 on Outposts 存储桶 (s3-outposts:DeleteObject) 删除一个名为 sample-object.xml 的对象。要使用此命令，请将每个 user input placeholder 替换为您自己的信息。有关此命令的更多信息，请参阅《AWS CLI 参考》中的 delete-object。

aws s3api delete-object --bucket arn:aws:s3-outposts:region:123456789012:outpost/op-01ac5d28a6a232904/accesspoint/example-outposts-access-point --key sample-object.xml

以下示例使用 AWS CLI 从 S3 on Outposts 存储桶 (s3-outposts:DeleteObject) 删除名为 sample-object.xml 和 test1.text 的两个对象。要使用此命令，请将每个 user input placeholder 替换为您自己的信息。有关此命令的更多信息，请参阅《AWS CLI 参考》中的 delete-objects。

aws s3api delete-objects --bucket arn:aws:s3-outposts:region:123456789012:outpost/op-01ac5d28a6a232904/accesspoint/example-outposts-access-point --delete file://delete.json

以下 S3 on Outposts 示例使用适用于 Java 的 SDK 删除存储桶中的对象。要使用此示例，请指定 Outpost 的访问点 ARN 和要删除的对象的密钥名称。有关更多信息，请参阅 Amazon Simple Storage Service API 参考中的 DeleteObject。
