Get mime type of image from storage?

Question

I'm getting a file from storage using:

$image = Storage::get('test.jpg');

How can I get it's mime type?

I've tried:

$mime = Storage::mimeType($image);

With no luck.

I need the mime type so I can return the image as a response:

$response = Response::make($image, 200);
$response->header('Content-Type', $mime);
return $response;

When using the Storage facade in a controller, you can return the image as a response in Laravel 5.7. The response() function will automatically set the headers required rather than attempting to do it yourself.

// Option #1
return Storage::response('test.jpg'); // Local storage
// Option #2
return Storage::disk('s3')->response('test.jpg'); // If you are using an S3 driver
// Option #3
return Storage::cloud()->response('test.jpg'); // Also S3 driver unless otherwise configured

This is not documented, but can be found by looking at the underlying Laravel code:

/vendor/laravel/framework/src/Illuminate/Filesystem/FilesystemAdapter.php

If you still need to get the mime type for any reason, you should be able to retrieve it by calling:

$mimeType = Storage::mimeType('test.jpg');
