我有这个问题 我的要求，我想让用户写入特定的路径

{
            "Sid": "raspiiotallowspecificBucket",
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::<bucketname>/scripts",
                "arn:aws:s3:::<bucketname>/scripts/*"
            ]
        },

这个改变解决了问题

{
            "Sid": "raspiiotallowspecificBucket",
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::<bucketname>",
                "arn:aws:s3:::<bucketname>/*"
            ]
        },

我得到了相同的错误时使用策略如下，虽然我有“s3:ListBucket”s3:ListObjects操作。

{
"Version": "2012-10-17",
"Statement": [
    {
        "Action": [
            "s3:ListBucket",
            "s3:GetObject",
            "s3:GetObjectAcl"
        ],
        "Resource": [
            "arn:aws:s3:::<bucketname>/*",
            "arn:aws:s3:::*-bucket/*"
        ],
        "Effect": "Allow"
    }
  ]
 }

然后我通过添加一行来修复它 “攻击:aws: s3::: bucketname”

{
"Version": "2012-10-17",
"Statement": [
    {
        "Action": [
            "s3:ListBucket",
            "s3:GetObject",
            "s3:GetObjectAcl"
        ],
        "Resource": [
             "arn:aws:s3:::<bucketname>",
            "arn:aws:s3:::<bucketname>/*",
            "arn:aws:s3:::*-bucket/*"
        ],
        "Effect": "Allow"
    }
 ]
}

遇到了类似的问题，对我来说，问题是我在bash_profile中设置了不同的AWS密钥。

我在这里回答了一个类似的问题:https://stackoverflow.com/a/57317494/11871462

如果bash_profile中有冲突的AWS密钥，AWS CLI会默认使用这些密钥。

您已经授予了对S3桶内的对象执行命令的权限，但没有授予对桶本身执行任何操作的权限。

稍微修改一下你的策略会是这样的:

{
  "Version": "version_id",
  "Statement": [
    {
        "Sid": "some_id",
        "Effect": "Allow",
        "Action": [
            "s3:*"
        ],
        "Resource": [
            "arn:aws:s3:::bucketname",
            "arn:aws:s3:::bucketname/*"
        ]
    }
  ] 
}

然而，这可能会给予超出所需的许可。遵循AWS IAM授予最小特权的最佳实践将看起来像这样:

{
  "Version": "2012-10-17",
  "Statement": [
      {
          "Effect": "Allow",
          "Action": [
              "s3:ListBucket"
          ],
          "Resource": [
              "arn:aws:s3:::bucketname"
          ]
      },
      {
          "Effect": "Allow",
          "Action": [
              "s3:GetObject"
          ],
          "Resource": [
              "arn:aws:s3:::bucketname/*"
          ]
      }
  ]
}

这不是最好的做法，但这将为你扫清障碍。 确保执行命令的用户在其权限下附加了以下策略。 答:PowerUserAccess b . AmazonS3FullAccess

我也有同样的问题。我必须提供正确的资源和行动，资源是你的桶的arn和行动在你想要的权限。另外，请确保您有正确的用户arn。以下是我的解决方案。

{
    "Version": "2012-10-17",
    "Id": "Policy1546414123454",
    "Statement": [
        {
            "Sid": "Stmt1546414471931",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::123456789101:root"
            },
            "Action": ["s3:ListBucket", "s3:ListBucketVersions"],
            "Resource": "arn:aws:s3:::bucket-name"
        }
    ]
}
