我在Google Go lang中实施AWS Request身份验证
package main
import "fmt"
import "crypto/hmac"
import "crypto/sha256"
import "time"
import "encoding/base64"
func main() {
AWSAccessKeyId := "MHAPUBLICKEY"
AWSSecretKeyId := "MHAPRIVATEKEY"
sha256 := sha256.New
time := time.Now().UTC().Format(time.ANSIC)
hash := hmac.New(sha256, []byte(AWSSecretKeyId))
hash.Write([]byte(time))
sha := base64.URLEncoding.EncodeToString(hash.Sum(nil))
fmt.Println("Date", time)
fmt.Println("Content-Type","text/xml; charset=UTF-8")
fmt.Println("AWS3-HTTPS AWSAccessKeyId=" + AWSAccessKeyId + ",Algorithm=HmacSHA256,Signature=" + sha)
}
我从亚马逊获得有效输出,但仅当'sha'哈希不包含任何_或 -
时工作
'WFKzWNQlZEyTC9JFGFyqdf8AYj54aBj5btxPIaGTDbM ='
不工作HTTP / 1.1 403 Forbidden SignatureDoesNotMatch
'h-FIs7of_CJ7LusAoQPzSWVt9hlXF_5gCQgedn_85lk ='
如何对AWS3-HTTPS标头进行编码,使其适用于任何一种情况?只是因为它是相关的,我目前正在复制并将输出粘贴到cURL中。我计划在Google Go中实现该请求,并使其可靠地运行。
答案 0 :(得分:4)
我发现我需要从URLEncoding更改为StdEncoding
sha = base64.URLEncoding.EncodeToString(hash.Sum(nil))
到
sha = base64.StdEncoding.EncodeToString(hash.Sum(nil))
