使用SSE

本文介绍了使用SSE-KMS的S3分段上传的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试使用aws-java-sdk(1.11.230)编写实用程序. 我可以使用PutObjectRequest通过SSE-KMS编写文件，如下所示:

I am trying to write a utility using aws-java-sdk (1.11.230). I am able to write a file with SSE-KMS by using PutObjectRequest as follow:

PutObjectRequest putRequest = new PutObjectRequest(existingBucketName, keyName, file) .withSSEAwsKeyManagementParams(kmsKeyId);

但是尝试分段上传时，找不到任何方法为SSE-KMS指定加密配置.

but while trying to upload it in multipart, I could not find any way to specify encryption configuration for SSE-KMS.

任何人都可以提出一种成功解决此问题的方法. 任何建议将不胜感激.

Could anyone please suggest a way to go through this successfully. Any suggestion will be appreciated.

推荐答案

最后，我能够找到解决方案.可以通过将标头设置为 InitiateMultipartUploadRequest 对象的标题来完成，如下所示:

Finally, I am able to find the solution for this. It can be done by setting headers to InitiateMultipartUploadRequest object as follow:

InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest(bucketName, keyName); initRequest.putCustomRequestHeader("x-amz-server-side-encryption", "aws:kms"); initRequest.putCustomRequestHeader("x-amz-server-side-encryption-aws-kms-key-id", kmsKey);
