TokenMismatchException when using Laravel 5.0 FileSystem

I want to pull an image file from some folder, and I'm trying to use the extension method from the FileSystem class that i found in the Laravel Filesystem API in my controller, but I get a TokenMismatchException. This is what I have in my controller:

use App\Http\Requests;
use App\Http\Controllers\Controller;

use Illuminate\Html\HtmlFacade;
use Illuminate\Filesystem\Filesystem;
use Filesystem;
use Request;
class PageController extends Controller{
    $image_extension = extension("C:/somepath/somefile");
    return view('display') ->with(compact('image_extension'));
}

What am I doing wrong?

Is it really like that?

you have to put the code inside a method which is also pointed in the routes.php file and when you get to that route (I am guessing POST), the code will execute.
The method extension() should be on a Flysystem object, you can't call it like that.

public function store(Request $request, Flysystem $flysystem) 
{
    $image = $request->file('name');
    // you should probably move the uploaded file somewhere before you can access it. (I believe a good idea would be in the public directory, or to a cloud service like AWS S3)
    $imageExtension = $flysystem->extension('path/to/file');
    return view('display', compact('imageExtension'));
}

That should give you an idea.

Oh and what's your form like? Do you have:

<form>
    <input type="hidden" name="_token" value="{!! csrf_token() !!}"> 
</form>

in your blade file? It will generate the the token in the value attribute.

I'm taking an image from a folder defined in the routes folder:

define('Server_directory','C:/somepath/server_directory');

Simulates a folder on a server. Is there a better way to do this? I am trying to take an image from this folder and display it in my blade file.
