如何更新 Amazon CDN (CloudFront) 上的文件? [英] How can I update files on Amazon's CDN (CloudFront)?

问题描述

有什么方法可以更新存储在 Amazon CloudFront(Amazon 的 CDN 服务)上的文件?似乎它不会对我们制作的文件进行任何更新(例如，删除文件并使用与以前相同的文件名存储新文件).我是否必须明确触发更新过程以从边缘服务器中删除文件才能发布新文件内容?

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?

Amazon 添加了失效功能.这是 API 参考.

Amazon added an Invalidation Feature. This is API Reference.

来自 API 参考的示例请求:

Sample Request from the API Reference:

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

<InvalidationBatch>
