amazon-web-services - 仅允许从 S3 存储桶的特定文件夹中删除的 IAM 策略

Question

我有一个桶：s3://mybucket

我只想允许删除下的对象s3://mybucket/test

我尝试了以下策略：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1604573937792",
            "Action": [
                "s3:DeleteObject"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::mybucket/",
                "arn:aws:s3:::mybucket/*"
            ],
            "Condition": {
                "StringLike": {
                    "s3:prefix": "test/*"
                }
            }
        }
    ]
}

但是，尝试删除对象的 IAM 策略模拟器arn:aws:s3:::mybucket/test/x.txt失败并显示“隐式拒绝（无匹配语句）”。我应该改变什么？

如果您查看Amazon S3 - AWS Identity and Access Management 的操作、资源和条件键，您会注意到DeleteObject不接受Prefix.

相反，您可以使用：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "s3:DeleteObject",
            "Resource": "arn:aws:s3:::mybucket/text/*"
        }
    ]
}
