可以上传文件但无法列出S3存储桶对象.获取访问被拒绝错误

Question

我正在尝试列出S3存储桶中的所有文件.但不断得到错误访问被拒绝.我想我的IAM用户拥有必要的权限:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "SID",
            "Effect": "Allow",
            "Action": [
                "s3:AbortMultipartUpload",
                "s3:DeleteObject",
                "s3:DeleteObjectVersion",
                "s3:GetBucketAcl",
                "s3:GetBucketCORS",
                "s3:GetBucketLocation",
                "s3:GetBucketLogging",
                "s3:GetBucketNotification",
                "s3:GetBucketPolicy",
                "s3:GetBucketRequestPayment",
                "s3:GetBucketTagging",
                "s3:GetBucketVersioning",
                "s3:GetBucketWebsite",
                "s3:GetLifecycleConfiguration",
                "s3:GetObject",
                "s3:GetObjectAcl",
                "s3:GetObjectTorrent",
                "s3:GetObjectVersion",
                "s3:GetObjectVersionAcl",
                "s3:GetObjectVersionTorrent",
                "s3:ListAllMyBuckets",
                "s3:ListBucket",
                "s3:ListBucketMultipartUploads",
                "s3:ListBucketVersions",
                "s3:ListMultipartUploadParts",
                "s3:PutBucketAcl",
                "s3:PutBucketCORS",
                "s3:PutBucketLogging",
                "s3:PutBucketNotification",
                "s3:PutBucketPolicy",
                "s3:PutBucketRequestPayment",
                "s3:PutBucketTagging",
                "s3:PutBucketVersioning",
                "s3:PutBucketWebsite",
                "s3:PutLifecycleConfiguration",
                "s3:PutObject",
                "s3:PutObjectAcl",
                "s3:PutObjectVersionAcl",
                "s3:RestoreObject"
            ],
            "Resource": [
                "arn:aws:s3:::bucket/*"
            ]
        }
    ]
}

我是否授予对S3的完全访问权限(AmazonS3FullAccess策略),我可以列出对象.可能是什么问题？我想我只删除了在自定义策略中删除和创建存储桶的权限.

当我添加对同一策略的完全访问权限时:

        "Action": [
            "s3:*"
        ],

我仍然无法列出对象.但是使用当前权限,我可以上传和删除对象.

Answer 1

刚刚找到答案!策略中允许的操作是正确的.问题在于Resource.我在用这个:

"Resource": [
   "arn:aws:s3:::bucket/*"
]

但看起来它没有授予存储桶根的权限.没有完全访问权限 所以,为了使它工作,我们必须删除/如下:

"Resource": [
   "arn:aws:s3:::bucket*"
]

现在它的工作就像一个魅力.
