Go语言实现
func GenSign(secret string, timestamp int64) (string, error) {
//timestamp + key 做sha256, 再进行base64 encode
stringToSign := fmt.Sprintf("%v", timestamp) + "\n" + secret
var data []byte
h := hmac.New(sha256.New, []byte(stringToSign))
_, err := h.Write(data)
if err != nil {
return "", err
}
signature := base64.StdEncoding.EncodeToString(h.Sum(nil))
return signature, nil
}
Java实现
public static String createSign(String appSecret, Long timestamp) throws Exception {
String stringToSign = timestamp + "\n" + appSecret;
Mac mac = Mac.getInstance("HmacSHA256");
mac.init(new SecretKeySpec(stringToSign.getBytes(), "HmacSHA256"));
byte[] signData = mac.doFinal();
return Base64.encodeBase64String(signData);
