在Laravel 4中替换File :: mime()(以从文件扩展名获取mime类型) [英] Replacement for File::mime() in Laravel 4 (to get mime type from file extension)

问题描述

Laravel 3的 File :: mime() 方法使从扩展名中获取文件的mime类型变得容易:

Laravel 3 had a File::mime() method which made it easy to get a file's mime type from its extension:

$extension = File::extension($path);
$mime = File::mime($extension);

升级到Laravel 4时出现错误:

On upgrading to Laravel 4 I get an error:

调用未定义的方法Illuminate \ Filesystem \ Filesystem :: mime()

在文件系统API文档中，我也看不到任何关于mime类型的提及. .

在Laravel 4中获取文件的mime类型的推荐方法是什么(请注意，这不是用户上传的文件)?

What's the recommended way to get a file's mime type in Laravel 4 (please note this is not a user-uploaded file)?

推荐答案

我发现的一个解决方案是使用

One solution I've found is to use the Symfony HttpFoundation File class (which is already included as a dependency in Laravel 4):

$file = new Symfony\Component\HttpFoundation\File\File($path);
$mime = $file->getMimeType();

实际上，File类使用 Symfony MimeTypeGuesser 类所以这也可行:

And in fact the File class uses the Symfony MimeTypeGuesser class so this also works:

$guesser = Symfony\Component\HttpFoundation\File\MimeType\MimeTypeGuesser::getInstance();
echo $guesser->guess($path);

但是不幸的是，我得到了意想不到的结果:将路径传递到CSS文件时，我得到的是 text/plain 而不是 text/css .

But unfortunately I'm getting unexpected results: I'm getting text/plain instead of text/css when passing a path to a css file.
