API 认证参数

所有接口都需要以下通用认证参数，请参考以下示例。

Name
AccessKeyId
Type
string
Description
用户的访问密钥 ID
Name
SignatureNonce
Type
string
Description
签名随机数
Name
Timestamp
Type
string
Description
请求时间戳（秒），有效期 30 秒
Name
Signature
Type
string
Description
使用 HmacSHA1 + Base64 生成的签名

参考示例

package main

import (
  "crypto/hmac"
  "crypto/sha1"
  "encoding/base64"
  "encoding/hex"
  "fmt"
  "math/rand"
  "strconv"
  "time"
)

// GenerateSignature 生成 API 签名
func GenerateSignature(accessKeyId, accessSecret string, signatureNonce *string, timestamp *int64) string {
  nonce := ""
  if signatureNonce == nil {
    b := make([]byte, 4)
    rand.Read(b)
    nonce = hex.EncodeToString(b)
  } else {
    nonce = *signatureNonce
  }

  ts := ""
  if timestamp == nil {
    ts = strconv.FormatInt(time.Now().Unix(), 10)
  } else {
    ts = strconv.FormatInt(*timestamp, 10)
  }

  str := fmt.Sprintf("AccessKeyId=%s&SignatureNonce=%s&Timestamp=%s",
    accessKeyId, nonce, ts)

  h := hmac.New(sha1.New, []byte(accessSecret))
  h.Write([]byte(str))
  hexSignature := hex.EncodeToString(h.Sum(nil))

  return base64.StdEncoding.EncodeToString([]byte(hexSignature))
}

func main() {
  accessKeyId := "975988f45090561684b7d8f4e45b85c2"
  accessSecret := "957f23f2d6435e37d4ac21f3e9a67d45"
  signatureNonce := "2"
  timestamp := int64(1612149637)

  newSignature := GenerateSignature(
    accessKeyId,
    accessSecret,
    &signatureNonce,
    &timestamp,
  )

  oldSignature := "M2Y0ODNlYTUwNDFiMTg5MjRmMGQxNmY1YTMyMzc1NTc5NTUzNDAzYw=="

  if newSignature == oldSignature {
    fmt.Println("签名验证成功")
  } else {
    fmt.Println("签名验证失败")
  }

  fmt.Println("新生成的签名:", newSignature)
}
