搭RestoreObject
配 AWS SDK或使用 CLI
下列程式碼範例會示範如何使用RestoreObject
。
- .NET
-
- AWS SDK for .NET
-
注意
還有更多關於 GitHub。尋找完整範例,並了解如何在AWS 設定和執行程式碼範例儲存庫

若要建立物件的還原要求
下列
restore-object
範例會將儲存貯體的指定 Amazon S3 Glacier 物件還原 10 天。my-glacier-bucket
aws s3api restore-object \ --bucket
my-glacier-bucket
\ --keydoc1.rtf
\ --restore-requestDays=10
此命令不會產生輸出。
