Go签名DEMO如下：
package main
import (
"crypto/hmac"
"crypto/sha256"
"encoding/hex"
"fmt"
"io/ioutil"
"net/http"
"net/url"
"sort"
"strings"
"time"
)
// 简易签名函数，使用HMAC-SHA256算法
func Sign(params map[string]string, secretKey string) string {
//对参数键进行排序
keys := make([]string, 0, len(params))
for k := range params {
keys = append(keys, k)
}
sort.Strings(keys)
//构建待签名字符串
var strEncode string
for _, k := range keys {
strEncode += url.QueryEscape(k) + "=" + url.QueryEscape(params[k]) + "&"
}
strEncode = strEncode[:len(strEncode)-1]
//生成HMAC-SHA256签名
h := hmac.New(sha256.New, []byte(secretKey))
h.Write([]byte(strEncode))
return hex.EncodeToString(h.Sum(nil))
}
func main() {
ak := "Your AK" //请替换为您的AccessKey
sk := "Your SK" //请替换为您的SecretKey
service := "iam" //访问的服务
region := "cn-beijing-6" //访问的区域
params := map[string]string{
//固定参数
"Accesskey": ak,
"Service": service,
"Region": region,
"Action": "ListUsers", //接口名称

}
signature := Sign(params, sk)
var requestURL strings.Builder
requestURL.WriteString(fmt.Sprintf("http://%s.api.ksyun.com/?", service))
for k, v := range params {
requestURL.WriteString(k + "=" + v + "&")
}
requestURL.WriteString("Signature=" + signature)
headers := map[string]string{
"Accept": "application/json",
