java - 如何使用 kms 角色将文件上传到 Amazon S3？

Question

我想从为我提供 IAM 凭证的环境将文件上传到 Amazon S3。但是我收到此错误:

使用 AWS KMS 托管 key 指定服务器端加密的请求需要 AWS 签名版本 4。(服务:Amazon S3；状态代码:400；错误代码:InvalidArgument；请求 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，并使用 putObject 方法将对象放入 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:

我的 aws sdk 版本是 - 1.11.163，默认情况下应该有签名版本 4。不知道问题出在哪里

我已经尝试在 putObject 中设置各种 SSEAlgorithm，例如 'AES256' 和 'AWS4-HMAC-SHA256' 但那些没有帮助。

任何线索都将受到重视。

Answer 1

我按照以下步骤解决了这个问题 -

1. 通过 PutObjectRequest 显式指定请求
2. 创建一个新的 ObjectMetadata 并为其设置 SSEAlgorithm - “aws:kms”。
3. 将objectMetadata附加到请求。
4. 通过 putObject 方法发送请求。

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);
