问题描述
我只是想在 CakePHP 中包含一个文件，但没有任何帮助。我已将该文件放在供应商文件夹中。
这是该文件的路径：
供应商/paytm/PaytmChecksum.PHP
我尝试将它导入到我的控制器中，如下所示：
require_once(ROOT . DS . 'vendor' . DS . 'paytm' . DS . 'PaytmChecksum.PHP');
但是没有用。所以，我尝试了另一种方法，在控制器顶部包含以下两行。
use Cake\Filesystem\File;
use Cake\Filesystem\Folder;
然后在控制器动作中这样做：
$dir = new Folder(ROOT . DS . 'vendor' . DS . 'paytm' . DS . 'PaytmChecksum.PHP');
但是没有什么对我有用。我尝试将该文件夹放在我的当前目录中，然后尝试将文件包含在 require_once 中，但这也不起作用。
有人可以帮忙吗？
解决方法
我也遇到了 paytm 校验和的问题。
所以我在组件中创建了一个文件。
......\src\Controller\Component\PaytmChecksumComponent.php
代码是。
<?php
namespace App\Controller\Component;
use Cake\Controller\Component;
define('PAYTM_ENVIRONMENT','TEST'); // PROD
define('PAYTM_MERCHANT_KEY','*********************'); //Change this constant's value with Merchant key received from Paytm.
define('PAYTM_MERCHANT_MID','*************'); //Change this constant's value with MID (Merchant ID) received from Paytm.
define('PAYTM_MERCHANT_WEBSITE','WEBSTAGING'); //Change this constant's value with Website name received from Paytm.
define('PAYTM_REFUND_URL','');

在控制器中加载组件
public function initialize(): void
{
parent::initialize();
//....................................
$this->loadComponent('PaytmChecksum');
//........................
}
// .............
function payment(){
//...$paytmParams = array(
"MID" => "*****","WEBSITE" => "DEFAULT","INDUSTRY_TYPE_ID" => "1","CHANNEL_ID" => "WEB","ORDER_ID" => "*************","CUST_ID" => "*****","MOBILE_NO" => "*****","EMAIL" => "*******","TXN_AMOUNT" => (float)100,/* on completion of transaction,we will send you the response on this URL */
"CALLBACK_URL" => "https://******",);
$checksum = $this->PaytmChecksum->getChecksumFromArray($paytmParams,"_@C%&uL");
pr($checksum);
}
