Kucoin C#签名发行

我正在尝试将bot写入Kucoin API，但由于创建签名而失败

var input = nonce;
var stringToSign = "/user/info/"+input+"/";
byte[] secretkeyBytes = Encoding.UTF8.GetBytes(SecretKey);
byte[] inputBytes = Encoding.UTF8.GetBytes(stringToSign);
using (var hmac = new HMACSHA256(secretkeyBytes))
{
byte[] hashValue = hmac.ComputeHash(inputBytes);
return BitConverter.ToString(hashValue).Replace("-", "").ToLower();
}

但任何时候都会出现错误：

{“code”：“UNAUTH”，“msg”：“签名验证” 失败，“成功”：false，“时间戳”：1}

在官方网站上，我们有这样的例子

String strForSign = endpoint + "/" + nonce +"/" + queryString;  

//Make a base64 encoding of the completed string
String signatureStr = Base64.getEncoder().encodeToString(strForSign.getBytes("UTF-8"));

Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
SecretKeySpec secretKeySpec = new SecretKeySpec(secret.getBytes("UTF-8"), "HmacSHA256");
sha256_HMAC.init(secretKeySpec);

//KC-API-SIGNATURE in header
String signatureResult =  Hex.encodeHexString(sha256_HMAC.doFinal(signatureStr.getBytes("UTF-8")));

我的代码出了什么问题？

您错过了输入数据的base64编码步骤。你需要像这样的东西：

// String interpolation just to be simpler; no need for input variable either
var stringToSign = $"/user/info/{nonce}/";

// This is the step you were missing
var signatureString = Convert.ToBase64String(Encoding.UTF8.GetBytes(stringToSign));

byte[] secretKeyBytes = Encoding.UTF8.GetBytes(SecretKey);
byte[] inputBytes = Encoding.UTF8.GetBytes(signatureString);
using (var hmac = new HMACSHA256(secretKeyBytes))
{
    byte[] hashValue = hmac.ComputeHash(inputBytes);
    return BitConverter.ToString(hashValue).Replace("-", "").ToLower();
}

我想发布我的代码，它可以工作并且包含正确的参数，因为Zimsan的代码包含参数的小错误
