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：
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.
