尝试编写脚本以从 Amazon S3 存储桶下载文件。
cURL 网站上的示例遇到问题。下面的脚本产生：
我们计算的请求签名与您的签名不匹配
假如。检查您的密钥和签名方法。
感谢任何帮助。
#!/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}
我编写这个bash脚本来从s3下载文件（我下载压缩文件，你可以更改contentType来下载其他类型的文件）
#!/bin/sh
outputFile="Your_PATH"
amzFile="AMAZON_FILE_PATH"
bucket="YOUR_BUCKET"
resource="/${bucket}/${amzFile}"
contentType="application/x-compressed-tar"
dateValue=`date -R`
stringToSign="GET\n\n${contentType}\n${dateValue}\n${resource}"
s3Key="YOUR_S3_KEY"
s3Secret="YOUR_S3SECRET"
signature=`echo -en ${stringToSign} | openssl sha1 -hmac ${s3Secret} -binary | base64`
curl -H "Host: ${bucket}.s3.amazonaws.com" \
-H "Date: ${dateValue}" \
-H "Content-Type: ${contentType}" \
-H "Authorization: AWS ${s3Key}:${signature}" \
https://${bucket}.s3.amazonaws.com/${amzFile} -o $outputFile
