Question

我对生成的文件有问题。这是我的行动：

<?php
public function exportAction()
{
    $this->checkSecurity('EDIT');

    $config = $this->getConfiguration();
    $resource = $this->findOr404();

    $style =  $this->render($config->getTemplate('export.css'), array(
        'resource' => $resource
    ));

    $response = new Response();
    $response->headers->set('Cache-Control', 'private');
    $response->headers->set('Content-type', 'plain/text');
    $response->headers->set('Content-type', 'application/octet-stream');
    $response->headers->set('Content-Disposition', 'attachment; filename="style-' . $resource->getSlug() . '.css";');
    $response->sendHeaders();
    $response->setContent($style);

    return $response;
}

我的文件已下载，但其内容的开头是：

HTTP/1.0 200 OK 
Cache-Control: no-cache 
Date:          Tue, 02 Sep 2014 09:16:34 GMT

有谁知道为什么？

Answer 1

我不会使用响应作为返回生成的文件进行下载。

我只需填写一个变量，然后显示如下：

  $style =  $this->render($config->getTemplate('export.css'), array(
    'resource' => $resource
  ));


    header("Content-Type: text/calendar; filename='style-" . $resource->getSlug() . ".css'");
    header('Content-Length: '.strlen($style);
    header("Content-Transfer-Encoding: binary");
    header("Content-Disposition: inline; filename='style-" . $resource->getSlug() . ".css'"); 
    header("Expires: 0");
    header("Cache-Control: no-cache, must-revalidate");
    header("Pragma: no-cache");

 echo $style;
 exit;

我知道这不是绝对的对象端代码，但它非常适合在我们的项目中每天生成数千个ics文件

我终于找到了解决方案。我忘记了渲染

上的getContent（）

<?php
public function exportAction()
{
    $this->checkSecurity('EDIT');

    $config = $this->getConfiguration();
    $resource = $this->findOr404();

    $style =  $this->render($config->getTemplate('export.css'), array(
        'resource' => $resource
    ));

    $response = new Response();
    $response->headers->set('Cache-Control', 'private');
    $response->headers->set('Content-type', 'plain/text');
    $response->headers->set('Content-type', 'application/octet-stream');
    $response->headers->set('Content-Disposition', 'attachment; filename="style-' . $resource->getSlug() . '.css";');
    $response->sendHeaders();
    $response->setContent($style->getContent());

    return $response;
}
