Amazon S3 Bucket Policy Public Access Denied

问题

I'm trying to make my S3 bucket public but when I add the following policy I get Error Access Denied:

{
   "Version":"2012-10-17",
   "Statement":[{
      "Sid":"AddPerm",
      "Effect":"Allow",
      "Principal":"*",
      "Action":[
         "s3:GetObject"
      ],
      "Resource":[
         "arn:aws:s3:::emergencydatascience.org/*"
      ]
    }]
}
