推荐答案
的确是这样。首先，你需要的是所有在较低的情况下，你的S3帐户创建一个水桶，是全球唯一的，DNS兼容;因此，例如我创建了一个名为斗media.torusknot.com。
Yes it is. Firstly, you need to create a bucket in your S3 account which is all in lower case, is globally unique and is DNS-compatible; so for example I created a bucket called ‘media.torusknot.com’.
然后使这一切看起来不错，你需要创建一个DNS CNAME进入您的网站的子域名映射到S3存储。这将允许您通过 http://media.example.com访问您的文件上传到S3存储/somefile.mp3 。你只需要设置的ACL上的文件和放大器;桶以确保公共访问是允许的。
Then to make it all look nice you need to create a DNS CNAME entry to map a sub-domain of your site to that S3 bucket. That will allow you to access your files you upload to that S3 bucket via ‘http://media.example.com/somefile.mp3’. You do just need to set the ACLs on the files & the bucket to make sure public access is allowed.
最后，如果你想通过Flash播放器从S3到另一个域流的视频文件，你还必须告诉Flash，这是确定的内容将在从不同的域拉升。创建一个名为crossdomain.xml的桶中的文件，这些内容：
Finally, if you want to stream video files via a Flash player from S3 to another domain, you also have to tell Flash that it’s ok for the content to be pulled in from a different domain. Create a file called ‘crossdomain.xml’ in the bucket, with these contents:
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
</cross>
从任何地方访问
这允许媒体 - 你可以，如果你想更具体的，但是这是最简单的方法
That allows the media to be accessed from anywhere - you can be more specific if you want but this is the simplest approach.
