使用 S3 CLI 访问被拒绝复制文件

Question

尝试使用 AWS CLI 提取 S3 存储桶的内容时，我得到以下信息：

aws s3 cp --region us-east-1 s3://s3.amazonaws.com/my-bucket . --recursive
A client error (AccessDenied) occurred when calling the ListObjects operation: Access Denied
Completed 1 part(s) with ... file(s) remaining

使用aws s3 sync同样失败。

用户政策是：

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

（我也尝试过各种限制较少的政策，但都无济于事）。

我已经尝试了一个空桶策略，还有这个桶策略：

{
    "Id": "Policy1357935677554",
    "Statement": [
        {
            "Sid": "Stmt1357935647218",
            "Action": [
                "*"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:s3:::my-bucket",
            "Principal": {
                "AWS": [
                    "arn:aws:iam::XXXXXXXXXX:user/my-user"
                ]
            }
        },
        {
            "Sid": "Stmt1357935676138",
            "Action": [
                "*"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:s3:::my-bucket/*",
            "Principal": {
                "AWS": [
                    "arn:aws:iam::XXXXXXXXXX:user/my-user"
                ]
            }
        }
    ]
}

有趣的是，这确实有效：

aws s3api list-objects --region us-east-1 --bucket my-bucket

Answer 1

指定 s3 位置的格式是s3://bucket/keyso 而不是s3://s3.amazonaws.com/my-bucket您将使用s3://my-bucket/.
