如何更新在亚马逊的CDN（CloudFront的）文件？ [英] How can I update files on Amazon's CDN (CloudFront)?

问题描述

有没有什么办法来更新存储在Amazon CloudFront的（亚马逊的CDN服务）的文件？ 好像它不会采取文件的任何更新，我们做（如删除文件，并像以前存储的新的使用相同的文件名）。 我必须明确地触发更新过程，请从边缘服务器中的文件，以获取新的文件内容发表？

Is there any way to update files stored on Amazon CloudFront (Amazon's CDN service)? Seems like it won't take any update of a file we make (e.g. removing the file and storing the new one with the same file name as before). Do I have to explicitly trigger an update process to remove the files from the edge servers to get the new file contents published?

感谢您的帮助

亚马逊增加了失效功能。 <一href="http://docs.amazonwebservices.com/AmazonCloudFront/latest/APIReference/index.html?Actions_Invalidations.html">This是参考。

Amazon added an Invalidation Feature. This is API Reference.

从API对照品请求：

POST /2010-08-01/distribution/[distribution ID]/invalidation HTTP/1.0
Host: cloudfront.amazonaws.com
Authorization: [AWS authentication string]
Content-Type: text/xml

<InvalidationBatch>

   <Path>/image2.jpg</Path>
   <Path>/videos/movie.flv</Path>
   <CallerReference>my-batch</CallerReference>
</InvalidationBatch>
