/admin/v1/users 在 DUO 安全管理 API 中提供 40103

问：

我正在尝试使用它显示的/admin/v1/users进行创建

{
 "code":40103,
 "message":"Invalid signature in request credentials",
 "stat":"FAIL"
  }

这是我的 Java 代码：

   public class DuoCreateUsers {

    private static SortedMap<String, Object> params = new TreeMap<String, Object>();

    public static void main(String[] args) throws IOException {
        String ikey = "x";
        String skey = "x";
        String host = "api-d221a358.duosecurity.com";
        String httpMethod = "POST";
        String requestPath = "/admin/v1/users";
        String timestamp = OffsetDateTime.now().format(DateTimeFormatter.RFC_1123_DATE_TIME);

        String username = "newuser";
        String email = "[email protected]";

        params.put("username",username);
        params.put("email",email);

        String queryString = canonQueryString();

        String canonicalRequest = timestamp + "\n" + httpMethod + "\n" + requestPath +  "\n" + queryString;
        System.out.println("canonicalRequest = " + canonicalRequest);

        String signature = sign1(canonicalRequest, skey);
      //  System.out.println("signature = " + signature);

        String url = "https://" + host + requestPath+"?"+queryString;
        System.out.println("url = " + url);

        HttpClient httpClient = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost(url);
        httpPost.setHeader("Date", timestamp);
        httpPost.setHeader("Authorization", "Basic " + Base64.getEncoder().encodeToString((ikey + ":" + signature).getBytes()));
        httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");


        httpPost.setEntity(new StringEntity(params.toString()));
        // Make the request
        HttpResponse response = httpClient.execute(httpPost);
        HttpEntity entity = response.getEntity();
        String responseContent = entity != null ? EntityUtils.toString(entity) : "";

        String rs =  "Response Status Code: " + response.getStatusLine().getStatusCode() + "\nResponse Content:\n" + responseContent;
        System.out.println("rs = " + rs);

    }


    public static String canonQueryString()
            throws UnsupportedEncodingException {
        ArrayList<String> args = new ArrayList<String>();

        for (String key : params.keySet()) {
            String name = URLEncoder
                    .encode(key, "UTF-8")
                    .replace("+", "%20")
                    .replace("*", "%2A")
                    .replace("%7E", "~");
            String value = URLEncoder
                    .encode(params.get(key).toString(), "UTF-8")
                    .replace("+", "%20")
                    .replace("*", "%2A")
                    .replace("%7E", "~");
            args.add(name + "=" + value);
        }

        return com.duosecurity.client.Util.join(args.toArray(), "&");
    }

    private static String sign1(String data, String secretKey) {
        try {

            // Create an HMAC-SHA1 key from the secret key
            SecretKeySpec secretKeySpec = new SecretKeySpec(secretKey.getBytes(StandardCharsets.UTF_8), "HmacSHA1");

            // Initialize the HMAC-SHA1 algorithm
            Mac mac = Mac.getInstance("HmacSHA1");
            mac.init(secretKeySpec);

            // Calculate the HMAC-SHA1 hash
            byte[] hmacSha1Bytes = mac.doFinal(data.getBytes(StandardCharsets.UTF_8));

            // Convert the result to a hexadecimal string
            String hmacSha1Hex = bytesToHex(hmacSha1Bytes);

            // Print the HMAC-SHA1 hash
            System.out.println("HMAC-SHA1: " + hmacSha1Hex);

            return hmacSha1Hex;
        } catch (NoSuchAlgorithmException | InvalidKeyException e) {
            e.printStackTrace();
        }

        return null;
    }

    // Helper method to convert bytes to a hexadecimal string
    private static String bytesToHex(byte[] bytes) {
        StringBuilder hexStringBuilder = new StringBuilder();
        for (byte b : bytes) {
            hexStringBuilder.append(String.format("%02x", b));
        }
        return hexStringBuilder.toString();
    }
}

我的代码有什么问题？

请帮帮我...
