Php html2pdf生成不正确的pdf

html2pdf_v4.03_php5在Symfony2.3上的应用

控制员：

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 %}

第二根树枝伸出：

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

    {% block content %}
    {% endblock %}

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

我得到了一些似乎是invamlid pdf的东西：

有谁能帮我看看怎样才能得到一个正确的pdf文件吗？

这可能不是一个无效的pdf文件

您传输的PDF文件内容类型错误，可能是text/html而不是application/PDF或application/force download。请尝试以下代码：

$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;
