如何提供对 aws s3 存储桶的公共访问？

Question

Amazon s3 我创建了一个存储桶并设置了 cloudwatch。正在生成用于审计和跟踪的日志。但是对于 s3，只能共享单个文件下载链接。任何将完整存储桶/文件夹设置为公共且用户可以访问的选项？我尝试更新存储桶策略但没有用。

Policy 我试过了。

{
  "Id": "Policy1397632521960",
  "Statement": [
    {
      "Sid": "Stmt1397633323327",
      "Action": [
        "s3:GetObject"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::bucketnm/*",
      "Principal": {
        "AWS": [
          "*"
        ]
      }
    }
  ]
}

但仍然低于问题。
