Signature签名计算

Signature = URLEncode(base64(hmac-sha1(AccessKeySecret, urlParam)))

python签名计算转java语言：

  public static String generateSignature(String accessKeySecret, String urlParam) throws Exception {
        // HMAC-SHA1 hashing
        Mac mac = Mac.getInstance("HmacSHA1");
        SecretKeySpec secretKeySpec = new SecretKeySpec(accessKeySecret.getBytes(StandardCharsets.UTF_8), "HmacSHA1");
        mac.init(secretKeySpec);

        byte[] hmacSha1Result = mac.doFinal(urlParam.getBytes(StandardCharsets.UTF_8));

        // Base64 encoding
        String base64Encoded = Base64.getEncoder().encodeToString(hmacSha1Result);

        // URL encoding
        String urlEncoded = URLEncoder.encode(base64Encoded, StandardCharsets.UTF_8.toString());

        return urlEncoded;
    }
