为什么 Symfony2 File->getMimeType() 为 CSS 文件返回 text/plain 而不是 text/css? [英] Why is Symfony2 File->getMimeType() returning text/plain not text/css for a CSS file?
问题描述
我需要获取服务器上文件的 MIME 类型.我正在使用 Laravel,但想使用来自 Symfony HTTPFoundation 的 File 类(请参阅我的相关问题).
I need to get the MIME type of a file on the server. I'm using Laravel but want to use the File class from Symfony HTTPFoundation (see my related question).
当我使用 文件->GetMimeType() 在 css 文件中,当我期待 text/css 时返回 text/plain.
When I use File->GetMimeType() on a css file, text/plain is returned when I'm expecting text/css.
$file = new Symfony\Component\HttpFoundation\File\File($path); //pass CSS file
$mime = $file->getMimeType(); //returns text/plain
我做错了什么?

然而,我的方法并不完美,但它适用于文件上传:只需从文件名中提取文件扩展名并使用 in:pdf,csv,css,..
规则.
However, my approach is not perfect, but it works for file uploads: just extract file extension from file name and check its presence in and array with in:pdf,csv,css,..
rule.
