Question

我正在尝试将paytm支付网关集成在cakephp中。

当我们选择paytm作为支付选项并且完成支付过程后，重定向到paytm服务器。pgresponse页面（回调URL）显示404错误
问题可能出在回调URL中。
我是Cakephp的初学者，对此了解不多。

PaytmController.php 页面代码

public function pgredirect($id = null)
{
    if($id != '') {
        $baseId = explode('@@', $id);
        foreach ($baseId as $key => $value) {
            $orderId[] = base64_decode($value); 
        }

        $customer_id = $this->Auth->user('id'); 

        $orderDetails = $this->Orders->find('all',[
            'conditions' =>[
                'Orders.id IN' => $orderId,
                'Orders.customer_id' => $customer_id
            ],
            'contain' => [
                'Restaurants' => [
                    'fields' => [
                        'Restaurants.id',
                        'Restaurants.restaurant_name',
                    ],
                ],
                'Carts'
            ]
        ])->hydrate(false)->toArray();

        if (!empty($orderDetails)) {

            $this->set(compact('orderDetails'));
        } else {
            return $this->redirect(BASE_URL);
        }
