HTML2PDF生成不正确的PDF

Question

应用上Symfony2.3与html2pdf_v4.03_php5

所述控制器：

public function printAction() 
{ 

    $em = $this->getDoctrine()->getManager(); 
    $entities = $em->getRepository('MyBundle:Activite')->findAll(); 
    $html=$this->get('templating')->render('MyBundle:Activite:print.html.twig',array('entities' => $entities,)); 

    //var_dump($html); 

    $html2pdf = new \Html2Pdf_Html2Pdf('P','A4','fr'); 
    $html2pdf->pdf->SetDisplayMode('real'); 
    $html2pdf->pdf->SetTitle('un pdf test'); 
    $html2pdf->writeHTML($html); 
    $html2pdf->Output('my-document-name.pdf'); 
} 

树枝：

{% extends "::html2pdf.html.twig" %} 

{% block content %} 

<div> 

    <h2>activite list</h2> 

    <table class="records_list"> 
     <thead> 
      <tr> 
       <th>Id</th> 
       <th>Name</th> 
       <th>Class</th> 
       <th>Position</th> 
      </tr> 
     </thead> 
     <tbody> 
     {% for entity in entities %} 
      <tr> 
       <td>{{ entity.id }}</td> 
       <td>{{ entity.name }}</td> 
       <td>{{ entity.class }}</td> 
       <td>{{ entity.position }}</td> 
      </tr> 
     {% endfor %} 
     </tbody> 
    </table> 

</div> 

{% endblock %} 

第二枝杈（扩展）：

<page> 
    <page_header> 
     <h1> Header </h1> 
    </page_header> 

    {% block content %} 
    {% endblock %} 

    <page_footer> 
     <h3> Footer</h3> 
    </page_footer> 
</page> 

我ge t东西似乎是invamlid pdf：

任何人都可以帮助我看看我能得到一个正确的PDF文件？

Answer 1

这可能是不是无效的PDF。

您正在传输PDF文件的内容类型错误，可能是text/html而不是application/pdf或application/force-download。试试这个代码：

$content = $html2pdf->Output('', true); 
$response = new Response(); 
$response->setContent($content); 
$response->headers->set('Content-Type', 'application/force-download'); 
$response->headers->set('Content-disposition', 'filename=my-document-name.pdf'); 
return $response;
