I m trying to implement worldpay on a PHP site using XML direct method but whenever I try to connect I get blank pag.. Can you tell me were you testing the payment gateway on live site.
Code:

    $url = 'https://secure.worldpay.com/sso/public/auth/login.html?serviceIdentifier=merchantadmin';

  $ch = curl_init();

  curl_setopt( $ch, CURLOPT_URL, $url );

  curl_setopt($ch, CURLOPT_USERPWD, "username

:password");

  curl_setopt( $ch, CURLOPT_POST, true );

  curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));

  curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

  curl_setopt( $ch, CURLOPT_POSTFIELDS, $xml );

  $result = curl_exec($ch);

  // curl_close($ch);

  // echo json_encode($result);

  // exit;

return $this->_pageFactory->create();

How to solve it?
Anyone can help me to solve this
i was used this payment-gateway .

1. This is the Data

dataFormat = array('temp_order_id'=>$qouteId, 'MobileNumber'=>$mobileNo, 'OTP'=>$otp, 'Amount'=>$amount); $response = $helper->getcurlDataArray($dataFormat,"username" => $merchant_user,"password" => $merchant_password, $adminUrl);

2. Here I'm calling Helper function

$response = $helper->getcurlDataArray($dataFormat,"username" => $merchant_user,"password" => $merchant_password, $adminUrl);

3. Here is the Helper function

public function getcurlDataArray($dataFormat,$username,$password,$service_url){



        $ch = curl_init($service_url);

        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($dataFormat));

        curl_setopt($ch, CURLOPT_USERPWD, $username. ":" .$password);

        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));

        $token = curl_exec($ch);

        if (curl_error($ch)) {

                $error_msg = curl_error($ch);

                $Errorhead = 'CurlError for Url:'.$service_url.' DataFormat:'.json_encode($dataFormat);

           $this->logError($Errorhead,$error_msg);

        }

        $response = json_decode($token,true);

       return $response;

}

dataFormat = array('temp_order_id'=>$qouteId, 'MobileNumber'=>$mobileNo, 'OTP'=>$otp, 'Amount'=>$amount); $response = $helper->getcurlDataArray($dataFormat,"username" => $merchant_user,"password" => $merchant_password, $adminUrl);

       $this->logError($Errorhead,$error_msg);

    }

    $response = json_decode($token,true);

   return $response;
