Symfony2提供打开的pdf文件

Question

I need to serve pdf files through the controller, but I can't make them open in browser window. 我需要通过控制器提供pdf文件，但我无法在浏览器窗口中打开它们。 When I send response with pdf file, it renders gibberish, or if I follow example at http://symfony.com/doc/current/components/http_foundation/introduction.html#serving-files it downloads the file, but I need to open it in view mode, how can I do that? 当我用pdf文件发送响应时，它会呈现乱码，或者如果我按照http://symfony.com/doc/current/components/http_foundation/introduction.html#serving-files中的示例，它会下载文件，但我需要在查看模式下打开它，我该怎么办？

Here's what I'v got so far: 这是我到目前为止所得到的：

return new Response(readfile('/file/path/file.pdf'), 200,
    array('Content-Type' => 'application/pdf')
);

Am I missing something, or maybe there's something wrong with my php or apache configuration? 我错过了什么，或者我的php或apache配置有问题吗？

Answer 1

Found a solution: 找到了解决方案：

Add BinaryFileResponse before controller class declaration from example 在示例中的控制器类声明之前添加BinaryFileResponse

use Symfony\Component\HttpFoundation\BinaryFileResponse;

In controller action return BinaryFileResponse 在控制器操作中返回BinaryFileResponse

return new BinaryFileResponse('/file/path/file.pdf');

I have the same issue 我有同样的问题

Try to add this : 尝试添加：

use \Symfony\Component\HttpFoundation\Response;
.......
return  $response->headers->set('Content-type' , 'application/pdf');
