java - 用 Java 签署 AWS S3 链接(包括版本控制)

Question

我有以下代码将 URL 签名到 S3 存储桶中的对象

https://docs.aws.amazon.com/AmazonS3/latest/dev/ShareObjectPreSignedURLJavaSDK.html

现在，如果 Bucket 启用了版本控制，我该如何签署特定版本的对象链接？

Answer 1

调用withVersionId(String) :

GeneratePresignedUrlRequest generatePresignedUrlRequest = 
                new GeneratePresignedUrlRequest(bucketName, objectKey)
                .withMethod(HttpMethod.GET)
                .withExpiration(expiration)
                .withVersionId("yourVesionId");

Sets the version ID of the object, only present if versioning has been enabled for the bucket.
