要解决这个问题，您需要在策略规则中找到Resource，并在数组中添加arn桶，一个带*，第二个末尾不带*。这将修复错误。

    "Id": "Policy3783783783738",
    "Statement": [
        {
            "Sid": "Stmt1615891730703",
            "Effect": "Allow",

                "AWS": "arn:aws:iam::76367367633:user/magazine-demo-root-user"
            },
            "Action": [
                "s3:ListBucket",
                "s3:ListBucketVersions",
                "s3:GetBucketLocation",
                "s3:DeleteObject",
                "s3:AbortMultipartUpload",
                "s3:Get*",
                "s3:Put*"
            ],
            "Resource": [
                "arn:aws:s3:::magazine-demo",
                "arn:aws:s3:::magazine-demo/*"
            ]
        }
    ]
}

它在注释中明确定义，有些服务不允许您为单个资源指定操作。

在Resource元素中使用通配符*

“资源”:“当arn: aws s3::: surplace-audio / *

来自IAM docs, http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html#Action

有些服务不允许您为单个资源指定操作;相反，您在Action或NotAction元素中列出的任何操作都应用于该服务中的所有资源。在这些情况下，在Resource元素中使用通配符*。

有了这些信息，resource的值应该如下所示:

"Resource": "arn:aws:s3:::surplace-audio/*"

您还可以为每个文件夹配置ListBuckets，如下所示

                }
            }
        },
        {
            "Sid": "Stmt1586754972129",

            },
            "Action": "s3:ListBucket",

                    "s3:delimiter": "/",
                    "s3:prefix": [
                        "",
                        "domain.co",
                        "domain.co/user"
                    ]
                }
            }
        },
        {
            "Sid": "Stmt1586754972129",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::596322993031:user/[red]"
            },
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::buckets.email",
            "Condition": {
                "StringLike": {
                    "s3:prefix": "domain.co/user/*"
                }
            }
        },
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::596322993031:user/[red]"
            },
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
            ],
            "Resource": "arn:aws:s3:::buckets.email/domain.co/user/*"
        }
    ]
}

这些规则与SES一起用于接收电子邮件，但允许外部用户查看SES放入bucket中的文件。 我按照这里的说明做了:https://aws.amazon.com/blogs/security/writing-iam-policies-grant-access-to-user-specific-folders-in-an-amazon-s3-bucket/

此外，必须将prefix指定为域。co/user/ WITH在使用SDK时，否则你将被拒绝访问。希望能对大家有所帮助

刚刚遇到了这个问题，并为那些想要在同一策略中拥有ListBucket和GetObject的人找到了一个更短的解决方案。重要的是在Resource下列出bucket-name和bucket-name/*。

{
  "Id": "Policyxxxx961",
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmtxxxxx4365",
      "Action": [
        "s3:GetObject",
        "s3:ListBucket",
        "s3:PutObject"
      ],
      "Effect": "Allow",
      "Resource": [
          "arn:aws:s3:::bucket-name",
          "arn:aws:s3:::bucket-name/*"
      ],
      "Principal": "*"
    }
  ]
}

您可能有几个策略语句，这个错误是非常普遍的。最好的方法是注释除任何一个以外的所有其他语句(如GetObject，或ListBuckets，或PutObject)并执行代码并查看。如果工作正常，就意味着ARN路径是正确的。否则，ARN应该单独包含桶名或包含/*的桶名。

一些资源(如ListBucket)接受ARN的全名，如“ARN:aws:s3:::bucket_name”，而GetObject或PutObject要求bucket_name后面有一个/*。根据服务更改arn，现在应该可以工作了!
