ruby-on-rails - "This XML file does not appear..."如何查看站点地图？

Question

当我访问 https://anthony-galli.s3.amazonaws.com/sitemaps/sitemap.xml.gz 时，如何查看站点地图的样子？我面临的是:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
<RequestId>25B779FB11146233</RequestId>
<HostId>
94TdmdgzvdGCMVfKFZYL7Z3JASDFSa18N1YdUoMCtNa3qx6UHajPfMQSeFqfDmgYFHf
</HostId>
</Error>

看起来我运行时正确构建了站点地图:

我按照本教程进行操作:http://cookieshq.co.uk/posts/creating-a-sitemap-with-ruby-on-rails-and-upload-it-to-amazon-s3/

If you don't have GetPolicy permissions, Amazon S3 returns a 403 Access Denied error. —http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketGETpolicy.html

将此策略(使用 https://awspolicygen.s3.amazonaws.com/policygen.html 创建)添加到您的 s3 存储桶，以允许公众访问特定文件夹 /sitemaps:

{
  "Id": "Policy1467935016977",
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1467935004623",
      "Action": [
        "s3:GetObject"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::anthony-galli/sitemaps/*",
      "Principal": "*"
    }
  ]
}
