当Symfony2控制器使用BinaryFileResponse响应返回文件时，是否可以设置自定义文件名?

Is it possible to set a custom filename when the file is returned by a Symfony2 controller using a BinaryFileResponse response?

推荐答案

是. BinaryFileResponse类具有方法setContentDisposition()，该方法将文件名作为第二个参数.

Yes. The BinaryFileResponse class has a method setContentDisposition() that takes the file name as the second argument.

第一个参数是文件的传递方式.如果要提供文件下载，则可以为ResponseHeaderBag::DISPOSITION_ATTACHMENT(或仅为字符串"attachment")，如果希望在浏览器中显示文件，则可以为ResponseHeaderBag::DISPOSITION_INLINE(或"inline").例如，对图像进行此操作.)

The first argument is the way the file should be delivered. It can be ResponseHeaderBag::DISPOSITION_ATTACHMENT (or just the string "attachment") if the file should be offered for downloading, or ResponseHeaderBag::DISPOSITION_INLINE (or "inline") if you want the file to be shown in the browser (you may want to do this with images, for example).

完整的代码示例:

<?php use Symfony\Component\HttpFoundation\BinaryFileResponse; use Symfony\Component\HttpFoundation\ResponseHeaderBag; $response = new BinaryFileResponse('/path/to/myfile'); $response->setContentDisposition( ResponseHeaderBag::DISPOSITION_ATTACHMENT, 'file_name.txt' );
