amazon-web-services - 可以上传文件，但不能列出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。但是不断出现错误，拒绝访问。我认为我的IAM用户具有必要的权限:

{
    "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/*"
            ]
        }
    ]
}

如果我授予对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，我可以上载和删除对象。

刚找到答案!该策略中允许的操作是正确的。问题出在Resource上。我正在使用这个:

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

但看起来它没有授予存储桶根目录的权限。没有完全访问权限。因此，要使其正常工作，我们必须像这样删除 /:

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

现在，它就像一种魅力一样工作。
