amazon-web-services - AWS - 服务器端加密访问被拒绝 - 更改根用户的加密失败

Question

我对我创建的 S3 存储桶具有读/写/管理员权限。我可以在那里创建对象并按预期删除它们。
存储桶上存在从另一个 AWS 账户传输到那里的其他文件夹。我无法从这些文件夹下载任何项目。
当我单击文件时，会显示“服务器端加密访问被拒绝”的信息。当我尝试删除此加密时，它失败并显示以下消息:

Forbidden (Service: Amazon S3; Status Code: 403; Error Code: 403 Forbidden; Request ID: 93A26842904FFB2D; S3 Extended Request ID: OGQfxPPcd6OonP/CrCqfCIRQlMmsc8DwmeA4tygTGuEq18RbIx/psLiOfEdZHWbItpsI+M1yksQ=)

我对问题是什么感到困惑。我是存储桶的根用户/所有者，虽然我可以更改此 Material 的权限/加密？

谢谢

您必须确保您仍然是 S3 存储桶中文件的所有者，而不是上传到它的其他 AWS 账户。

S3 存储桶策略示例:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "allowNewDataToBeUploaded",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::$THE_EXTERNAL_ACCOUNT_NUMBER:root"
            },
            "Action": [
                "s3:PutObject",
                "s3:PutObjectAcl"
            ],
            "Resource": "arn:aws:s3:::$THE_BUCKET_NAME/*"
        },{
            "Sid": "ensureThatWeHaveOwnershipOfAllDataUploaded",
            "Effect": "Deny",
            "Principal": {
                "AWS": "arn:aws:iam::$THE_EXTERNAL_ACCOUNT_NUMBER:root"
            },
            "Action": "s3:PutObject",
            "Resource": "arn:aws:s3:::$THE_BUCKET_NAME/*",
            "Condition": {
                "StringNotEquals": {
                    "s3:x-amz-acl": "bucket-owner-full-control"
                }
            }
        }
    ]
}

外部帐户还必须使用 x-amz-acl他们请求中的 header :

ObjectMetadata metaData = new ObjectMetadata();
metaData.setContentLength(byteArrayLength);
metaData.setHeader("x-amz-acl", "bucket-owner-full-control");

s3Client.putObject(new PutObjectRequest(bucketNameAndFolder, fileKey, fileContentAsInputStream, metaData));
