Laravel 5文件下载无效 [英] Laravel 5 file downloads invalid

问题描述

使用Response::download下载文件时，我注意到图像和其他二进制文件传输不正确.

When using Response::download to download files, I noticed that images and other binary files were being transferred incorrectly.

更改Content-Type标头没有任何改变，也没有明确禁止缓存或强制内容的长度.

Changing the Content-Type header didn't change anything, nor did explicitly disallowing cache or forcing the content's length.

此问题可能是什么原因?

问题的原因是由于Laravel/Symfony由于某些原因未正确清理输出缓冲区，因此解决方案是这样的:

The cause of the issue was due to Laravel/Symfony not properly cleaning the output buffer for some reason, so the solution is this:

$response = Response::download($path, ...);
ob_end_clean();

return $response;
