Symfony 2 Kpn snappy生成带有输出的pdf符合安全区域 [英] Symfony 2 kpn snappy generate pdf with output meets security area

问题描述

我使用Symfony2 kpn snappy捆绑包生成pdf.我想从带有CSS的html页面生成PDF.我找到了一个解决方案，但它有一个问题:

I`m using Symfony2 kpn snappy bundle to generate pdfs. I want to generate PDF from an html page with css. I found a solution, but it has a problem with :

    $pageUrl = $this->generateUrl('accounts_management_generate_pdf_markup',
    array('invoice' => $invoiceData), true); // use absolute path!

    return new \Symfony\Component\HttpFoundation\Response(
        $this->get('knp_snappy.pdf')->getOutput($pageUrl), 200, array(
        'Content-Type' => 'application/pdf',
        'Content-Disposition' => 'attachment; filename="file.pdf"'
        )
    );

问题在于，pageUrl accounts_management_generate_pdf_markup位于安全区域的后面，未经身份验证就无法访问.生成的文件只是登录页面，如果没有登录，此路径accounts_management_generate_pdf_markup会重定向到该页面.

The problem is that the pageUrl accounts_management_generate_pdf_markup is behind a security area and cannot be accessed without authentication. The generated file is just the login page, to which this path accounts_management_generate_pdf_markup redirects if not logged.

我的问题是:

有什么方法可以传递给快速的身份验证凭据?
是否有另一种方法使用snappy bundle使用styles(css)生成pdf

Is there any way to pass to snappy authentication credentials?
Is there another way using snappy bundle to generate the pdf using styles(css)

推荐答案

您可以将会话cookie作为参数添加到getOutput函数:

You can add the session cookie as an argument to the getOutput function:

        $pageUrl = $this->generateUrl('route', array('id' => $id), true);
        $session = $this->get('session');
        $session->save();
        session_write_close();

        return new Response(
            $this->get('knp_snappy.pdf')->getOutput($pageUrl, array('cookie' => array($session->getName() => $session->getId()))),
            200,
            array(
                'Content-Type'          => 'application/pdf',
                'Content-Disposition'   => 'attachment; filename="file.pdf"'
            )
        );
