AWS2认证过程怎么实现

这篇文章主要讲解了"AWS2认证过程怎么实现"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"AWS2认证过程怎么实现"吧！

很多新手司机看官方文档AWS2认证部分特别是Authorization怎么生成的总是晦涩难懂，其核心就是StringToSign到底怎么构成

Authorization = "AWS" + " " + AWSAccessKeyId + ":" + Signature;Signature = Base64( HMAC-SHA1( YourSecretAccessKeyID, UTF-8-Encoding-Of( StringToSign ) ) );StringToSign = HTTP-Verb + "\n" +    Content-MD5 + "\n" +    Content-Type + "\n" +    Date + "\n" +    CanonicalizedAmzHeaders +    CanonicalizedResource;

下面以使用bash向S3上传一个Object为例，具体解释一下整个AWS2的签名过程

#!/bin/bashACCESS_KEY="" #填access keySECRET_KEY="" #填secret keyHOST="s3.cephbook.com" #填S3的Endpoint地址BUCKET="demo" #填bucket名称CONTENT_TYPE="application/octet-stream" #MIMEFILENAME=/tmp/demo #文件本地路径ACL="x-amz-acl:public-read" #Object的ACLMETA_DATA="x-amz-meta-ukey:value" #自定义medadataFILESIZE=$(stat -c%s "$FILENAME")FILEMD5=`cat ${FILENAME}| openssl dgst -md5 -binary | openssl enc -base64`AUTH_PATH="/${BUCKET}${FILENAME}"CURRENT_TIME=`TZ=GMT LANG=en_US date "+%a, %d %b %Y %H:%M:%S GMT"`stringToSign="PUT\n${FILEMD5}\n${CONTENT_TYPE}\n${CURRENT_TIME}\n${ACL}\n${META_DATA}\n${AUTH_PATH}"echo $stringToSignsignature=`echo -en ${stringToSign} | openssl sha1 -hmac ${SECRET_KEY} -binary | base64`curl -s -v -X PUT "http://${HOST}${AUTH_PATH}" \-H "Authorization: AWS ${ACCESS_KEY}:${signature}" \-H "Date: ${CURRENT_TIME}" \-H "Host: ${HOST}" \-H "Content-Length: ${FILESIZE}" \-H "Content-MD5: ${FILEMD5} " \-H "Content-Type: ${CONTENT_TYPE} " \-H "${ACL} " \-H "${META_DATA} " \-T "${FILENAME}"
