How can I set a bucket in Amazon S3 so all the files are publicly read-only by default?

推荐答案

您可以设置一个水桶政策，在这个博客帖子详细说明：

You can set a bucket policy as detailed in this blog post:

根据@ robbyt的建议，建立一个水桶政策，以下JSON：

As per @robbyt's suggestion, create a bucket policy with the following JSON:

{
  "Version": "2008-10-17",
  "Statement": [{
    "Sid": "AllowPublicRead",
    "Effect": "Allow",
    "Principal": { "AWS": "*" },
    "Action": ["s3:GetObject"],
    "Resource": ["arn:aws:s3:::bucket/*" ]
  }]
}

重要：替换斗与你的水桶的名称资源行

Important: replace bucket in the Resource line with the name of your bucket.
