在CakePHP中使用ccavenue支付网关

我正在使用CakePHP 3.2 . 我必须将CCAvenue支付网关集成到我的网站 .

我正在使用https://github.com/kishanio/CCAvenue-PHP-Library库将CCAvenue整合到我的网站中 .

但是通过composer安装它是行不通的

composer require kishanio/ccavenue

所以，我下载并提取所有文件

/vendor/CCAvenue-PHP-Library-master

Payment.php 的路径

/vendor/CCAvenue-PHP-Library-master/src/Payment.php

在 controller ，我做得很好

<?php
namespace App\Controller;

use App\Controller\AppController;
use Cake\Event\Event;
require_once(ROOT.'/vendor/CCAvenue-PHP-Library-master/src/Payment.php');

use Kishanio\CCAvenue\Payment as CCAvenueClient;
class OrdersController extends AppController
{
    public function paymentViaPaymentGateway($invoice = null)
    {

          $payble_amount = 500;

          $ccavenue = new CCAvenueClient('key', 'id', 'redirect');

          // set details
          $ccavenue->setAmount($payble_amount);
          $ccavenue->setOrderId($invoice);
          $ccavenue->setBillingName($getOrder->user_address->name);
          $ccavenue->setBillingAddress($getOrder->user_address->line_1);
          $ccavenue->setBillingCity($getOrder->user_address->city);
          $ccavenue->setBillingZip($getOrder->user_address->postal);
          $ccavenue->setBillingState($getOrder->user_address->state);
          $ccavenue->setBillingCountry('India');
          $ccavenue->setBillingEmail($this->Auth->user('email'));
          $ccavenue->setBillingTel($this->Auth->user('mobile'));
          $ccavenue->setBillingNotes($invoice);

          // copy all the billing details to shipping details
          $ccavenue->billingSameAsShipping();

          // get encrypted data to be passed
          $data = $ccavenue->getEncryptedData();

          // merchant id to be passed along the param
          $merchant = $ccavenue->getMerchantId();

          $this->set('data', $data);
          $this->set('merchant', $merchant);
    }
}

Utils.php 与 Payment.php 位于同一目录中，而Payment.php包含

namespace Kishanio\CCAvenue;

use Kishanio\CCAvenue\Utils;

和 Utils.php 包含

namespace Kishanio\CCAvenue;

use Kishanio\CCAvenue\Payment;

But, this gives error as

致命错误：第243行的/path_to/vendor/CCAvenue-PHP-Library-master/src/Payment.php中找不到类'Kishanio \ CCAvenue \ Utils'

Payment.php的内容，指出错误 .

public function getEncryptedData() {
  $utils = new Utils( $this );           // line 243
  $merchant_data = $this->getMerchantData( $utils->getChecksum() );
  return $utils->encrypt($merchant_data,$this->getWorkingKey());
}
