Javascript 使用RESTAPI的Payumoney支付网关集成

我正在开发使用angular和后端nodejs、express和mongodb的完全restful前端web应用程序。我正在尝试将payumoney支付网关与我的web应用程序集成。当我点击支付端点时，Plz通过这个api返回html页面。我不知道如何让用户重定向到payumoney支付页面。在此之前，我得到的错误校验和失败。iam正在以这种格式发送数据

您的散列丢失请尝试在php中使用sha512算法生成散列，

不允许jquery请求您必须使用form post方法发送所有参数

您需要在继续之前计算请求数据的哈希值，根据您应该在服务器端创建哈希值的文档，以下是示例代码：

<?php
error_reporting(0);

$salt = "eCwWELxi"; # salt value need to be picked from your database
$amount = $_POST["amount"]; # amount need to be picked up from your database
$reverseHash = generateReverseHash();

if ($_POST["hash"] == $reverseHash) {
    # transaction is successful
    # do the required javascript task
    echo("Transaction Success & Verified");
    AndroidSuccess($_POST["amount"]);
}
else{
    # transaction is tempered
    # handle it as required
    echo("<br>");
    echo "\nInvalid transaction";
}

# For Android Success
function AndroidSuccess($input) {
    echo '<script type="text/javascript">';
    echo 'PayU.onSuccess("Amount =" +'.$_POST["amount"].')';
    echo "</script>";
}

# Function to generate reverse hash
function generateReverseHash() {
    global $salt;
    global $amount;
    if ($_POST["additional_charges"] != null) {
        $reversehash_string = $_POST["additional_charges"] . "|" . $salt . "|" . $_POST["status"]  . "||||||" . $_POST["udf5"] . "|" . $_POST["udf4"] . "|" . $_POST["udf3"] . "|" . $_POST["udf2"] . "|" . $_POST["udf1"] . "|" .
        $_POST["email"] . "|" . $_POST["firstname"] . "|" . $_POST["productinfo"] . "|" . $amount . "|" . $_POST["txnid"] . "|" . $_POST["key"] ;
    }
    else{
        $reversehash_string =  $salt . "|" . $_POST["status"]  . "||||||" . $_POST["udf5"] . "|" . $_POST["udf4"] . "|" . $_POST["udf3"] . "|" . $_POST["udf2"] . "|" . $_POST["udf1"] . "|" .
             $_POST["email"] . "|" . $_POST["firstname"] . "|" . $_POST["productinfo"] . "|" . $amount . "|" . $_POST["txnid"] . "|" . $_POST["key"] ;
    }

//  echo($reversehash_string);
    $reverseHash = strtolower(hash("sha512", $reversehash_string));
    return $reverseHash;
}

缺少使用SHA512的校验和。是否可以执行此操作。如果是，你能分享代码吗？我正在尝试类似的方法并寻找一些参考代码嗨，你是否使用rest APIThank@John Conde获得输出：如何将payumoney整合到angular6/7/8中？
