# 在 Zend Framework 中的示例使用

public function webshotAction()
{
        $params = array(
          'url' => 'http://google.pl',
          'hash' => '2131sada', //unique identifcator of service
          'sign' => 'adad13123' //sign key for http://google.pl + 2131sada
        );
        
        $url = 'yourdomain/api/create';            
        $client = new Zend_Http_Client($url);
        $client->setMethod(Zend_Http_Client::POST)
               ->setHeaders('X-Requested-With', 'XMLHttpRequest') 
               ->setParameterPost($params)
               ->setConfig(array('timeout' => 180));
        
        $response = $client->request();
        
        $return = Zend_Json::decode($response->getBody());
        $code = isset($return['code']) ? $return['code'] : 200;
    
      if ($code === 200) {
          $this->_helper->viewRenderer->setNoRender(true);
          $this->_helper->layout->disableLayout();
          
          $content = file_get_contents($return['image']);
          $this->getResponse()->setHeader('Content-type', 'image/png');
          $this->getResponse()->setBody($content);
          $this->getResponse()->sendResponse();  
        } else {
          throw new Exception('An error on generate screenshot');
        }
    }
