Guzzle or Curl For Handling Vpos Requests ?

Hi,

I'm converting my e-commerce project to Laravel. I was using cURL for vpos requests.

$ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $this->_server);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_HEADER, FALSE);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_TIMEOUT, 90);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $vPOSData);

        $ch = curl_exec($ch);
        @curl_close ($ch);
        return $ch;

When i dd for $VPosData i get correct results. But i'm getting blank page. I think there exists a problem with cURL in Laravel.

In my project it is working but in Laravel it fails. Some of friends in Stack offers me Guzzle.

I tried Guzzle like

    $client = new Client();
    return $client->post($this->_server, $vPOSData);

Also it fails and i got a blank page. I stucked. What should i do ?

Normally the system post data the bank. And redirects 3D secure page for sms password. But blank page and no redirecting.
