AWS S3 ListMultipartUploads：访问被拒绝-Java 学习之路

我已关注this blog，以便使用Web Identity Federation设置我的AWS IAM和S3帐户 . 我能够验证和接收会话凭证和令牌都很好 . 我也可以下载和上传对象 . 但是，我得到了：

访问被拒绝

在以下ListMultipartUploads请求中：

var request = new ListMultipartUploadsRequest()
{
    BucketName = bucketName,
    Prefix = $"{UserId}/"
};

var response = await s3Client.ListMultipartUploadsAsync(request);

附加到我的IAM角色的访问策略是：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:AbortMultipartUpload",
                "s3:DeleteObject",
                "s3:GetObject",
                "s3:PutObject"
            ],
            "Resource": "arn:aws:s3:::mybucket/${myidentityprovider:userId}/*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket",
                "s3:ListBucketMultipartUploads"
            ],
            "Resource": [
                "arn:aws:s3:::mybucket"
            ],
            "Condition": {
                "StringLike": {
                    "s3:prefix": "${myidentityprovider:userId}/"
                }
            }
        }
    ]
}

如您所见，我拥有“s3：ListBucketMultipartUploads”权限，因此用户应该能够在其存储桶上执行ListMultiPartUploads . 我究竟做错了什么？

我在你的前缀语句中看到一个错误，

它需要是一个数组，

“s3：prefix”：[“$ {myidentityprovider：userId} / *”]

{
"Version": "2012-10-17",
"Statement": [
    {
        "Effect": "Allow",
        "Action": [
            "s3:AbortMultipartUpload",
            "s3:DeleteObject",
            "s3:GetObject",
            "s3:PutObject"
        ],
        "Resource": "arn:aws:s3:::mybucket/${myidentityprovider:userId}/*"
    },
    {
        "Effect": "Allow",
        "Action": [
            "s3:ListBucket",
            "s3:ListBucketMultipartUploads"
        ],
        "Resource": [
            "arn:aws:s3:::mybucket"
        ],
        "Condition": {
            "StringLike": {
                "s3:prefix": ["${myidentityprovider:userId}/*"]
            }
        }
    }
]}
