带有Cloudfront / CDN的预签名S3 URL [英] Pre-Signed S3 URLs with Cloudfront/CDN

问题描述

是否可以生成CDN的预签名URL（即CloudFront？），还是可以将预签名URL参数附加到CloudFront URL上以代替使用？

Is it possible to generate pre-signed URLs for CDNs (i.e., CloudFront?), or can I append pre-signed URL parameters to a CloudFront URL to use instead?

示例：

string url = amazonS3Client.generatePresignedUrl(generatePresignedUrlRequest);

返回：

url = "https://bucket-name.s3.amazonaws.com/file.txt?AWSAccessKeyId=XXXXXXXXXXXXXXXXXXXX&Expires=1111111111&Signature=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

我可以使用URL参数并附加到相应的CloudFront URL：

Can I take the URL parameters and append to corresponding CloudFront URL:

https://00000000000000.cloudfront.net/file.txt?AWSAccessKeyId=XXXXXXXXXXXXXXXXXXXX&Expires=1111111111&Signature=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

这项工作可以允许下载文件吗？

Will this work to allow download of the file?

推荐答案

仅供参考优化而不是边缘缓存，您还可以考虑使用 Amazon S3 Transfer Acceleration： https://docs.aws.amazon.com/AmazonS3/latest/dev/transfer-acceleration.html

FYI if you only want the network optimization, and not the edge caching, you can also consider using "Amazon S3 Transfer Acceleration": https://docs.aws.amazon.com/AmazonS3/latest/dev/transfer-acceleration.html

哟u继续使用S3签名，而不必实施Cloudfront签名。

This allows you to keep using S3 signatures, rather than having to implement Cloudfront signatures.
