java - 如何使用 kms 角色将文件上传到 Amazon S3？

问题描述

我想将文件从提供 IAM 凭证的环境上传到 Amazon S3。但是我收到此错误：

Requests specifying Server Side Encryption with AWS KMS managed keys require AWS Signature Version 4. (Service: Amazon S3; Status Code: 400; Error Code: InvalidArgument; Request ID: EF93490A8356F585)

IAM 角色如下：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::sam-94a493b-dev"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:DeleteObject"
            ],
            "Resource": [
                "arn:aws:s3:::sam-bbcb194a493b-dev/*"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "kms:Encrypt",
                "kms:Decrypt"
            ],
            "Resource": [
                "arn:aws:kms:us-east-1:000351272236:key/9b7a989c-ee8e-4c83-b765-6debe0f94eaa"
            ]
        }
    ]
}

我使用默认客户端访问 Amazon S3 客户端和putObject方法将对象放入具有fileNameWithPath(path/in/s3/filename.ext) 的存储桶中访问 s3 的代码如下：

AmazonS3 s3client = AmazonS3ClientBuilder.defaultClient();
s3client.putObject(bucketName, fileNameWithPath, file)

我得到的错误是：


com.amazonaws.services.s3.model.AmazonS3Exception: Requests specifying Server Side Encryption with AWS KMS managed keys require AWS Signature Version 4. (Service: Amazon S3; Status Code: 400; Error Code: InvalidArgument; Request ID: EF93490A8356F585)

我的 aws sdk 版本是 -1.11.163默认情况下应该有签名版本 4。我不确定问题出在哪里

我已经尝试在“AES256”和“ putObjectAWS4 -HMAC-SHA256”中设置各种 SSEAlgorithm，但这些都没有帮助。

任何线索都将被应用。

解决方案

我按照以下步骤解决了这个问题 -

  1. 明确指定request通过PutObjectRequest
  2. 创建一个new ObjectMetadata并设置SSEAlgorithm它 - “aws:kms”。
  3. 附加objectMetadata到request.
  4. 发送requestviaputObject方法。

这是代码 -

    PutObjectRequest request = new PutObjectRequest(bucketName, ruleFilePath, file);
    ObjectMetadata objectMetadata = new ObjectMetadata();
    objectMetadata.setSSEAlgorithm("aws:kms");
    request.setMetadata(objectMetadata);
    this.s3client.putObject(request);
