如何生成和验证节点JS中给定字符串的校验和

问题描述：

我想在节点Js中重写下面的函数来生成校验和并验证支付事务，而我在Node Js中编写代码还很新。如何生成和验证节点JS中给定字符串的校验和

我得到了服务提供的代码，我需要将其转换为Node Js。我使用express作为我的后端。

<?php 

    function generateChecksum($transId,$sellingCurrencyAmount,$accountingCurrencyAmount,$status, $rkey,$key) 
    { 
     $str = "$transId|$sellingCurrencyAmount|$accountingCurrencyAmount|$status|$rkey|$key"; 
     $generatedCheckSum = md5($str); 
     return $generatedCheckSum; 
    } 

    function verifyChecksum($paymentTypeId, $transId, $userId, $userType, $transactionType, $invoiceIds, $debitNoteIds, $description, $sellingCurrencyAmount, $accountingCurrencyAmount, $key, $checksum) 
    { 
     $str = "$paymentTypeId|$transId|$userId|$userType|$transactionType|$invoiceIds|$debitNoteIds|$description|$sellingCurrencyAmount|$accountingCurrencyAmount|$key"; 
     $generatedCheckSum = md5($str); 
//  echo $str."<BR>"; 
//  echo "Generated CheckSum: ".$generatedCheckSum."<BR>"; 
//  echo "Received Checksum: ".$checksum."<BR>"; 
     if($generatedCheckSum == $checksum) 
      return true ; 
     else 
      return false ; 
    } 
?>

如何使用传递参数在Javascript中编写以下代码。

看一看一些MD5实现这个[SO]（https://stackoverflow.com/questions/14733374/how-to-generate-md5-file-hash-on-javascript）问题。 –

答

var crypto = require('crypto'); 
function generateChecksum(transId,sellingCurrencyAmount,accountingCurrencyAmount,status, rkey,key) 
{ 
    var str = `${transId}|${sellingCurrencyAmount}|${accountingCurrencyAmount}|${status}|${rkey}|${key}`; 
    var generatedCheckSum = crypto.createHash('md5').update(str).digest("hex"); 
    return generatedCheckSum; 
} 

function verifyChecksum(paymentTypeId, transId, userId, userType, transactionType, invoiceIds, debitNoteIds, description, sellingCurrencyAmount, accountingCurrencyAmount, key, checksum) 
{ 
    var str = `${paymentTypeId}|${transId}|${userId}|${userType}|${transactionType}|${invoiceIds}|${debitNoteIds}|${description}|${sellingCurrencyAmount}|${accountingCurrencyAmount}|${key}`; 
    var generatedCheckSum = crypto.createHash('md5').update(str).digest("hex"); 

    if(generatedCheckSum == checksum) 
     return true ; 
    else 
     return false ; 
}
