如何使用kms角色將文件上傳到Amazon S3？

Question

我想從提供IAM憑據的環境中將文件上傳到Amazon S3。 但是我收到此錯誤：

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"
            ]
        }
    ]
} 

我使用默認客戶端訪問Amazon S3客戶端，並使用putObject方法將一個對象放入具有fileNameWithPath （path / in / s3 / filename.ext）的存儲桶中，用於訪問s3的代碼如下：

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

我得到的錯誤是：

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 ，默認情況下應該具有簽名版本4。 我不確定問題出在哪里

我已經嘗試在putObject設置各種SSEAlgorithm，例如“ AES256”和“ AWS4-HMAC-SHA256”，但這些操作沒有幫助。

任何線索將被應用。

我按照以下步驟解決了這個問題-

1. 通過PutObjectRequest明確指定request
2. 創建一個new ObjectMetadata並將SSEAlgorithm設置為它-“ aws：kms”。
3. 將objectMetadata附加到request 。
4. 通過putObject方法發送request 。

這是代碼-

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