与 AWS SDK或UploadPartCopy
一起使用 CLI
以下代码示例演示如何使用 UploadPartCopy
。
操作示例是大型程序的代码摘录,必须在上下文中运行。在以下代码示例中,您可以查看此操作的上下文:
- CLI

通过从现有对象中复制数据作为数据源来上传部分对象
以下
upload-part-copy
示例通过从现有对象复制数据作为数据源来上传部件。aws s3api upload-part-copy \ --bucket
my-bucket
\ --key"Map_Data_June.mp4"
\ --copy-source"my-bucket/copy_of_Map_Data_June.mp4"
\ --part-number1
\ --upload-id"bq0tdE1CDpWQYRPLHuNG50xAT6pA5D.m_RiBy0ggOH6b13pVRY7QjvLlf75iFdJqp_2wztk5hvpUM2SesXgrzbehG5hViyktrfANpAD0NO.Nk3XREBqvGeZF6U3ipiSm"
输出:
{ "CopyPartResult": { "LastModified": "2019-12-13T23:16:03.000Z", "ETag": "\"711470fc377698c393d94aed6305e245\"" } }

System.out.println("Upload Part Copy completed successfully. ETag: " + uploadPartCopyResponse.copyPartResult().eTag()); } }); return null; }
