#!/bin/sh 
file="filename.php"
bucket="my-bucket"
resource="/${bucket}/${file}"
contentType="text/html"
dateValue="`date +'%a, %d %b %Y %H:%M:%S %z'`"
stringToSign="GET\n\n${contentType}\n${dateValue}\n${resource}"
s3Key='ABCABCABCABCABCABCAB'
s3Secret='xyzxyzyxyzxyzxyzxyzxyzxyzxyzxyzxyzxyzxyzx'
signature=`/bin/echo -en "$stringToSign" | openssl sha1 -hmac ${s3Secret} -      binary | base64`

curl -v -H "Host:lssngen-updates-east.s3.amazonaws.com" \
        -H "Date:${dateValue}" \
        -H "Content-Type:${contentType}" \
        -H "Authorization: AWS ${s3Key}:${signature}" \
        https://${bucket}.s3.amazonaws.com/${file}

推荐答案

避免自己签署请求，这可能会出错或很难做.例如，您应该检查日期是否设置为GMT或使用x-amz-date标头.

Avoid signing the request yourself, a lot can go wrong or be hard to do. For example, you should check that the date is set to GMT or use x-amz-date headers.

另一种方法是使用 AWS命令行界面，然后使用$ aws s3 cp或$ aws s3 sync.

Another approach is to use the AWS Command Line Interface and so use $ aws s3 cp or $ aws s3 sync.
