Question

我想从提供IAM凭据的环境中将文件上传到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，并使用putObject方法使用fileNameWithPath将对象放入存储桶（path / in / s3 / filename.ext）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版本为-1.11.163，默认情况下应具有签名版本4。我不确定问题出在哪里

我已经尝试在putObject中设置各种SSEAlgorithm，例如'AES256'和'AWS4-HMAC-SHA256'，但是这些没有帮助。 / p>

任何线索都将被应用。

我按照以下步骤解决了这个问题-

通过request明确指定PutObjectRequest
创建一个new ObjectMetadata并将其设置为SSEAlgorithm-“ aws：kms”。
将objectMetadata附加到request。
通过request方法发送putObject。

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);

如何使用kms角色将文件上传到Amazon S3？
