从EC2实例下载AWS S3文件 [英] Download AWS S3 file from EC2 instance
问题描述
我有一个脚本可以从AWS S3下载文件，并且可以在AWS之外的单独服务器上工作.但是，当我将此脚本放在EC2实例上并尝试使用它时，它将返回错误"SignatureDoesNotMatch-我们计算出的请求签名与您提供的签名不匹配.请检查您的密钥和签名方法."
I've a script to download file from AWS S3 and it works from a separate server outside of AWS. But when I put this script on an EC2 instance and tried it then it returns error "SignatureDoesNotMatch - The request signature we calculated does not match the signature you provided. Check your key and signing method."
但是它可以在另一台服务器上使用. ec2与s3主机位于同一区域.我猜它与主机有关.我尝试了这些主机/URL，但它返回了相同的错误.
But it works on the other server. The ec2 is on the same region as the s3 host. I'm guessing it has something to do with the host. I tried these host/url but it returns the same error.
任何人都可以通过curl从ec2下载s3文件吗?我只需要使用卷发.如果您知道如何卷曲，请回答.谢谢.

推荐答案
Rather than writing a CURL command, consider using the AWS Command-Line Interface (CLI).
它具有aws s3 cp命令，该命令可以将内容复制到Amazon S3存储桶或从Amazon S3存储桶复制内容(甚至在存储桶之间).
It has a aws s3 cp command that can copy content to/from Amazon S3 buckets (and even between buckets).
