Amazon CloudFront与S3->限制域访问？ [英] Amazon CloudFront vs. S3 --> restrict access by domain?
问题描述
在Amazon S3上，您可以按域限制对存储桶的访问。
On Amazon S3, you can restrict access to buckets by domain.
但是据我从一个有用的StackOverflow用户那里了解，您不能在CloudFront上执行此操作。但为什么？如果我是正确的，CloudFront仅允许基于时间的限制或IP限制（->所以我需要知道随机访问者的IP .. ?？）还是我遗漏了什么？
But as far as I understand from a helpful StackOverflow user, you cannot do this on CloudFront. But why? If I am correct, CloudFront only allows time-based restrictions or IP restrictions (--> so I need to know the IP's of random visitors..?) Or am I missing something?
这里是S3文档的引文，表明可能对每个域进行限制：
Here is a quote from S3 documentation that suggests that per-domain restriction is possible:
--->允许从您的目录读取这些对象在网站上，您可以使用aws：referer键添加允许条件带有s3：GetObject权限的存储桶策略，该条件必须使get请求必须源自特定网页。
---> " To allow read access to these objects from your website, you can add a bucket policy that allows s3:GetObject permission with a condition, using the aws:referer key, that the get request must originate from specific webpages. "
->有没有办法使这种方法也可以在CloudFront上工作？还是为什么在CloudFront上不提供这样的服务？
--> Is there a way to make this method work on CloudFront as well? Or why something like this is not available on CloudFront?
->是否有类似的服务可能且更容易设置？
--> Is there a similar service where this is possible, easier to setup?
推荐答案
结合使用CloudFront和WAF（Web应用程序防火墙），您可以基于IP地址，引荐来源网址或域来限制请求。
Using CloudFront along with WAF (Web Application Firewall), you can restrict requests based on IP address, referrers, or domains.
这是有关限制热链接的AWS博客教程。
Here is a AWS blog tutorial on restricting "hotlinking".
在此示例中，它禁止请求 Referrer：标头与特定域不匹配的请求。
In this example, it prohibits requests where the Referrer: header does not match a specific domain.
