我正在尝试将payumoney与angularjs集成。但它显示错误，例如校验和失败＆＃39;。
(function ()
{
'use strict';
angular
.module('app.todo')
.controller('TodoController', TodoController);
/** @ngInject */
function TodoController($document, $mdDialog, $mdSidenav, Tasks, Tags,$scope,$crypthmac)
{
var vm = this;
vm.txnid = "fd3e847h2";
vm.firstname = "Hemanth";
vm.email = "kevinguru888@gmail.com";
vm.phone = "9901996148";
vm.service_provider = "payu_paisa";
vm.productinfo = "steering";
vm.amount = "399.00";
vm.surl = "http://localhost:3000/success";
vm.furl = "http://localhost:3000/failure";
vm.key = "OygoFs";
vm.salt = "BV1QBwCv";
var string = vm.key + '|' + vm.txnid + '|' + vm.amount + '|' + vm.productinfo + '|' + vm.firstname + '|' + vm.email + '|||||||||||' + vm.salt;
vm.hash = $crypthmac.encrypt(string,"");
}
})();

错误显示为＆＃34; SORRY！我们无法处理您的付款Checksum失败＆＃34;。
答案 0 :(得分：0)
当表单中的哈希值和传递值不匹配时，会发生此错误。 如果你传递2 udf，那么你也必须以名字的形式发送它。
如果你传递相同但仍然得到相同的错误，那么这是因为哈希生成中的问题。您正在使用$crypthmac，但它不会创建完美的哈希值，无法创建使用或拥有sha512算法，或使用API来创建完美哈希。您可以检查$crypthmac创建的哈希是不是完美地PayUMoney完美解密它，这就是它返回错误的原因。只需检查已生成$crypthmac和<?php echo hash('sha512', 'text') ?>即可获得差异。
