我在JavaScript中生成哈希字符串时遇到了问题

我正在尝试将支付网关作为一个模块集成到WHMCS中;脚本没有按照以下格式生成hashkey;&支付网关返回信息未完成错误;因此;参考：以下URL工作正常：
示例代码由网关的作品100%：https://websol.biz/order/modules/gateways/test.php

Hashkey Generated as per following format

/**
 * WHMCS Jazzcash Payment Gateway Module
 *
 * Payment Gateway modules allow you to integrate payment solutions with the
 * WHMCS platform.
 *
 * This sample file demonstrates how a payment gateway module for WHMCS should
 * be structured and all supported functionality it can contain.
 *
 * Within the module itself, all functions must be prefixed with the module
 * filename, followed by an underscore, and then the function name. For this
 * example file, the filename is "jazzcash" and therefore all functions
 * begin "jazzcash_".
 *
 * If your module or third party API does not support a given function, you
 * should not define that function within your module. Only the _config
 * function is required.
 *
 * For more information, please refer to the online documentation.
 *
 * @see https://developers.whmcs.com/payment-gateways/

C#开发者代码

为键值创建简单类模型

public class KeyValueModel
{
    public string Key { get; set; }
    public string Value { get; set; }
}

为Json对象创建Jazz Cash模型以用于发布请求

var model = new JazzCashModel
{
    pp_Version = "1.1",
    pp_TxnType = "MWALLET",
    pp_Language = "EN",
    pp_MerchantID = "MC58085",
    pp_SubMerchantID = "",
    pp_Password = "33t8ve7s5z",
    pp_BankID = "",
    pp_ProductID = "",
    pp_TxnRefNo = "T20230623141244",
    pp_Amount = "50000",
    pp_TxnCurrency = "PKR",
    pp_TxnDateTime = "20230623141244",
    pp_BillReference = "billref",
    pp_Description = "Description of transaction",
    pp_TxnExpiryDateTime = "20230623141244",
    pp_ReturnURL = "www.fqmsys.com",
    pp_SecureHash = "",
    ppmpf_1 = "03426791550",
    ppmpf_2 = "",
    ppmpf_3 = "",
    ppmpf_4 = "",
    ppmpf_5 = ""
};

创建键值模型的列表

var list = new List<KeyValueModel>();

list.Add(new KeyValueModel { Key = "pp_Version", Value =model.pp_Version});
list.Add(new KeyValueModel { Key = "pp_TxnType", Value =model.pp_TxnType});
list.Add(new KeyValueModel { Key = "pp_Language", Value =model.pp_Language});
list.Add(new KeyValueModel { Key = "pp_MerchantID", Value =model.pp_MerchantID});
list.Add(new KeyValueModel { Key = "pp_SubMerchantID", Value =model.pp_SubMerchantID});
list.Add(new KeyValueModel { Key = "pp_Password", Value =model.pp_Password});
list.Add(new KeyValueModel { Key = "pp_BankID", Value =model.pp_BankID});
list.Add(new KeyValueModel { Key = "pp_ProductID", Value =model.pp_ProductID});
list.Add(new KeyValueModel { Key = "pp_TxnRefNo", Value =model.pp_TxnRefNo});
list.Add(new KeyValueModel { Key = "pp_Amount", Value =model.pp_Amount});
list.Add(new KeyValueModel { Key = "pp_TxnCurrency", Value =model.pp_TxnCurrency});
list.Add(new KeyValueModel { Key = "pp_TxnDateTime", Value =model.pp_TxnDateTime});
list.Add(new KeyValueModel { Key = "pp_BillReference", Value =model.pp_BillReference});
list.Add(new KeyValueModel { Key = "pp_Description", Value =model.pp_Description});
list.Add(new KeyValueModel { Key = "pp_TxnExpiryDateTime", Value =model.pp_TxnExpiryDateTime});
list.Add(new KeyValueModel { Key = "pp_ReturnURL", Value =model.pp_ReturnURL});
list.Add(new KeyValueModel { Key = "ppmpf_1", Value =model.ppmpf_1});
list.Add(new KeyValueModel { Key = "ppmpf_2", Value =model.ppmpf_2});
list.Add(new KeyValueModel { Key = "ppmpf_3", Value =model.ppmpf_3});
list.Add(new KeyValueModel { Key = "ppmpf_4", Value =model.ppmpf_4});
list.Add(new KeyValueModel { Key = "ppmpf_5", Value =model.ppmpf_5});

使用键对列表进行排序

list = list.OrderBy(x => x.Key).ToList();
var hash = "";
foreach (var item in list)
{
    if (string.IsNullOrEmpty(item.Value))
    {
        continue;
    }
    if (list.IndexOf(item)!=0 && (list.IndexOf(item) < list.Count - 1))
    {
        if (!string.IsNullOrEmpty(item.Value))
        {
            hash += "&";
        }
    }
    hash += item.Value;
   
}

使作为哈希字符串和计算哈希与盐你的盐密钥和哈希

var secure_has = ComputeHashWithSalt(hash,saltKey);

一种哈希计算方法

string ComputeHashWithSalt(string input, string salt)
{
string combinedString =   salt+"&"+input;
byte[] saltKeyBytes = Encoding.UTF8.GetBytes(salt);
byte[] inputBytes = Encoding.UTF8.GetBytes(combinedString);
using (HMACSHA256 sha256 = new HMACSHA256(saltKeyBytes))
{
   
    byte[] hashBytes = sha256.ComputeHash(inputBytes);
    string hashedString = BitConverter.ToString(hashBytes).Replace("-", "");
    return hashedString;
}

}
