Laravel 5.5 change unauthenticated login redirect url

Question

In Laravel < 5.5 I could change this file app/Exceptions/Handler to change the unauthenticated user redirect url:

protected function unauthenticated($request, AuthenticationException $exception)
{
    if ($request->expectsJson()) {
        return response()->json(['error' => 'Unauthenticated.'], 401);
    }

    return redirect()->guest(route('login'));
}

But in Laravel 5.5 this has been moved to this location vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.php so how can I change it now? I don't want to change stuff in the vendor directory encase it gets overridden by composer updates.

protected function unauthenticated($request, AuthenticationException $exception)
{
    return $request->expectsJson()
                ? response()->json(['message' => 'Unauthenticated.'], 401)
                : redirect()->guest(route('login'));
}

It's just the case that the function is not there by default anymore.

You can just override it as you did in 5.4. Just make sure to include

use Exception;
use Request;
use Illuminate\Auth\AuthenticationException;
use Response;

in the Handler file.

For Example my app/Exceptions/Handler.php looks somewhat like this:

<?php
    namespace App\Exceptions;
    use Exception;
    use Request;
    use Illuminate\Auth\AuthenticationException;
    use Response;
    use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
    class Handler extends ExceptionHandler
    {
        (...) // The dfault file content
        /**
         * Convert an authentication exception into a response.
         *
         * @param  \Illuminate\Http\Request  $request
         * @param  \Illuminate\Auth\AuthenticationException  $exception
         * @return \Illuminate\Http\Response
         */
         protected function unauthenticated($request, AuthenticationException $exception)
         {
            return $request->expectsJson()
                    ? response()->json(['message' => 'Unauthenticated.'], 401)
                    : redirect()->guest(route('authentication.index'));
    }
}

Here's how I solved it. In render function I caught exception class. And in case if it's Authentication exception class I wrote my code for redirect (the code I would write in unauthenticated function in previous version).

public function render($request, Exception $exception)
{
    $class = get_class($exception);

    switch($class) {
        case 'Illuminate\Auth\AuthenticationException':
            $guard = array_get($exception->guards(), 0);
            switch ($guard) {
                case 'admin':
                    $login = 'admin.login';
                    break;
                default:
                    $login = 'login';
                    break;
            }

            return redirect()->route($login);
    }

    return parent::render($request, $exception);
}

We need to just include the use Illuminate\Auth\AuthenticationException;

and then it works as in laravel 5.4
