【中文标题】错误：- "code":"403", "message":"HMAC 验证失败"【英文标题】：error :- "code":"403", "message":"HMAC validation Failure"错误：- "code":"403", "message":"HMAC 验证失败" 【发布时间】：2015-06-04 16:54:43 【问题描述】：我在这里附上代码和一个包含完整代码的链接，看看它：- 我的授权标题接缝的长度与 payeezy 官方网站中提到的长度相同。我也使我的 hmacString 的顺序与此链接 (https://developer.payeezy.com/content/hmac-validation-failure) 中提到的相同。完成所有这些后，我仍然遇到同样的问题
public static String excutePost(String urlParameters) throws IOException
URL url = new URL("https://api-cert.payeezy.com/v1/transactions");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
try
// Create connection
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", headerContentType);
connection.setRequestProperty("apikey ", apikey);
connection.setRequestProperty("token", MerchantToken);
connection
.setRequestProperty("Authorization", authorizationHeader);
connection.setRequestProperty("timestamp", ""+epoch);
connection.setRequestProperty("nonce", ""+nonce);
connection.setDoOutput(true);
connection.setReadTimeout(30000);
// Send request
DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
// Get Response
InputStream is = connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
String line;
StringBuffer response = new StringBuffer();
while ((line = rd.readLine()) != null)
response.append(line);
response.append('\r');
rd.close();
return response.toString();
catch (Exception e)
e.printStackTrace();
return null;
finally
if (connection != null)
connection.disconnect();
这里是完整的 java 类代码：- http://piratepad.net/ep/pad/view/ro.WwZ9v6FX1a6/latest
【问题讨论】：
【参考方案1】：您必须为每个请求生成一个新的timestamp 和nonce，即每个新请求都必须有其唯一的timestamp 和nonce。
在java中，timestamp可以设置为System.currentTimeMillis()，nonce可以使用UUID(UUID.randomUUID().toString())设置。
最后，确保您的 Authorization 计算正确（我看到他们使用 API 密钥使用 HMAC-SHA1）。
我希望这会有所帮助。
编辑：怀疑是您的HMAC-SHA1 Authorization 值不正确。运行您的代码时，我得到以下响应（经过我自己的几次编码）。
Connection = keep-alive
Content-Length = 51
Content-Type = application/json
"code":"403", "message":"HMAC validation Failure"
确保您正确计算您的 HMAC-SHA1 值（正如我上面所说的）。
请参阅以下（更新的）代码，您可以自己编译和运行这些代码。您现在需要 Java 8，因为它带有 Base 64 编码器/解码器。

嘿，谢谢您的回复，是的，我知道我必须在每次点击 api 时生成我的时间戳和随机数向您发送我的主要 java 类...请看看它并告诉我我做错了什么... (piratepad.net/ep/pad/view/ro.WwZ9v6FX1a6/latest) 嘿，谢谢你的努力，我会试试，让你知道它是怎么回事:) 嘿，Sindi ..我只是在我的机器上运行你的代码，是的，我遇到了你上面提到的同样的问题......我没有更新我的 java 版本的 eclipse，但使用了 java。 util,base64 class from this site(grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/…) 你能告诉我我应该使用哪种方法来生成我的 Hmac 密钥。谢谢 您是否运行了您编辑的代码并对其进行了测试？你得到了什么结果？【参考方案2】：我唯一的问题是字符编码，我假设是 UTF-8。我怀疑错误出在其他地方。
// Send request
byte[] data = urlParameters.getBytes(StandardCharsets.UTF_8);
BufferedOutputStream wr = new BufferedOutputStream(connection.getOutputStream());
wr.writeBytes(data);
wr.close();
// Get Response
InputStream is = connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is,
StandardCharsets.UTF_8));
并且\r，CR，不作为行分隔符（除了旧的 MacOS）。
response.append("\r\n"); // Or '\n'

嘿，Eggen 感谢您的回复......但我仍然收到同样的错误：- java.lang.IllegalArgumentException：消息头值中的非法字符：AMru2osZZnotc25nRr7/dAOwkV/S3J1T7Yn7zs2XpFc= 另外，当我尝试调试代码时，我发现类似：- java.lang.IllegalStateException: 已经连接 尽量省略结尾的= 填充字符。
对不起，我没明白你的意思……你能详细说明一下吗，谢谢
Base64 键的值末尾有多余的等号。你可以试试没有。还有什么？ URLEncoder.encode(value) 可能仍然是另一个更可疑的尝试。【参考方案3】：
我终于通过在 api url hit 中发送直接字符串作为参数来解决这个错误。这里我发布了一些我的代码来解决我的错误：-
String str = "\"amount\":\"1299\",\"merchant_ref\":\"Astonishing-Sale\",\"transaction_type\":\"authorize\",\"credit_card\":\"card_number\":\"4788250000028291\",\"cvv\":\"123\",\"exp_date\": \"1020\",\"cardholder_name\": \"John Smith\",\"type\": \"visa\",\"method\": \"credit_card\",\"currency_code\": \"USD\"";现在这个字符串将用于生成我的授权密钥。 整个过程定义如下 :-
getSecurityKeys(apikey, pzsecret,str);
private static Map<String, String> getSecurityKeys(String appId,
String secureId, String payLoad) throws Exception
Map<String, String> returnMap = new HashMap<String, String>();
try
returnMap.put(NONCE, Long.toString(nonce));
returnMap.put(APIKEY, appId);
returnMap.put(TIMESTAMP, Long.toString(System.currentTimeMillis()));
returnMap.put(TOKEN, MerchantToken);
returnMap.put(APISECRET, pzsecret);
returnMap.put(PAYLOAD, payLoad);
returnMap.put(AUTHORIZE, getMacValue(returnMap));
authorizationHeader = returnMap.get(AUTHORIZE);
return returnMap;
catch (NoSuchAlgorithmException e)
throw new RuntimeException(e.getMessage(), e);
public static String getMacValue(Map<String, String> data) throws Exception
Mac mac = Mac.getInstance("HmacSHA256");
String apiSecret = data.get(APISECRET);
SecretKeySpec secret_key = new SecretKeySpec(apiSecret.getBytes(),
"HmacSHA256");
mac.init(secret_key);
StringBuilder buff = new StringBuilder();
buff.append(data.get(APIKEY)).append(data.get(NONCE))
.append(data.get(TIMESTAMP));
if (data.get(TOKEN) != null)
buff.append(data.get(TOKEN));
if (data.get(PAYLOAD) != null)
buff.append(data.get(PAYLOAD));
byte[] macHash = mac.doFinal(buff.toString().getBytes("UTF-8"));
String authorizeString = Base64.encodeBase64String(toHex(macHash));
return authorizeString;
希望它可以帮助其他人在不使用任何依赖项的情况下集成 payeezy 支付网关。 快乐编码！！！
