允许下载到特定IP地址的S3访问策略

Question

我正在尝试实现一个批量病毒扫描程序。我设置了一个cron作业来定期扫描存储在S3上的未扫描文件。每当我尝试获取该文件时，我都会得到一个403。

我已经设置了这个策略：

{
    "Version": "2012-10-17",
    "Id": "S3PolicyIPRestrict",
    "Statement": [
        {
            "Sid": "IPAllow",
            "Effect": "Allow",
            "Principal": {
                "AWS": "*"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::bucket/*",
            "Condition": {
                "IpAddress": {
                    "aws:SourceIp": "ip of my address/32"
                }
            }
        }
    ]
}

知道我做错了什么吗？

如果您想要允许特定ip地址访问s3存储桶上的文件，请使用下面的存储桶策略。

​

{
    "Version": "2012-10-17",
    "Id": "S3PolicyId1",
    "Statement": [
        {
            "Sid": "IPAllow",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::<bucket>",
                "arn:aws:s3:::<bucket>/*"
            ],
            "Condition": {
                "IpAddress": {
                    "aws:SourceIp": "<IP>/32"
                }
            }
        }
    ]
}
