在从控制器方法返回之前,是否可以在Laravel 5中设置Cookie()?

I have some sample code within a controller method that looks up a cookie and manipulates the model if it exists, or creates a new model and returns a new cookie if it doesn't.

Is it possible to add the cookie before I return the view such that the duplicated code can be written only once?

I'm just looking for efficiency and tidiness.

$cat = Cat::find($request->cookie('cat_id'));
if (null !== $cat) {
    if ($cat->name === 'Felix') {
        $cat->age = 10;
    } else {
        $cat->age = 8;
    }

    //duplicated code
    $cat->fur = 'soft';
    $cat->tail = 'wavy';
    $cat->save();

    return redirect('/');

} else {
    $cat = new Cat;
    $cat->name = 'Ralf';
    $cat->age = 12;

    //duplicated code
    $cat->fur = 'soft';
    $cat->tail = 'wavy';
    $cat->save();

    return redirect('/')->withCookie(cookie('cat_id', $cat->id,10000));
}

    The redirect() method returns a Illuminate\Http\RedirectResponse when a string is passed to it, which the Laravel routing stack interprets as a direction to send out a particular response header. So instead of returning twice, you can just do this:

    $cat = Cat::find($request->cookie('cat_id'));
    $redirect = redirect('/');
    
    if (null !== $cat) {
        if ($cat->name === 'Felix') {
            $cat->age = 10;
        } else {
            $cat->age = 8;
        }
    
        //duplicated code
        $cat->fur = 'soft';
        $cat->tail = 'wavy';
        $cat->save();
    } else {
        $cat = new Cat;
        $cat->name = 'Ralf';
        $cat->age = 12;
    
        //duplicated code
        $cat->fur = 'soft';
        $cat->tail = 'wavy';
        $cat->save();
    
        $redirect->withCookie(cookie('cat_id', $cat->id,10000));
    }
    
    return $redirect;
