How to specify a language for a single request in Lumen?

I need to show a simple page (view) in the user's language, but it's not so easy in Lumen.

As long as Lumen has no sessions support I can't just log in a user to use his locale:

Auth::login($user);

Auth::onceUsingId($user->id);

Any ideas?

You can use a middleware to set the language of the user

public function handle(Request $request, $next)
{
     $user = $request->user();

     app('translator')->setLocale($user->locale);
}
