laravel auth中间件：一条路线，两条视图

I am building a store so i could learn laravel. Like most stores, users can add items to a cart but cannot checkout until they register. How do i have the same route return a user name when authorized and a nothing when an authorized. This seemed very easy to me at first:

@if(Auth::guest())
  Nothing || or login/register buttons
@else
  {{ Auth::user()->name }}
@endif

That works well when you have content that should only be visible to loyal users but for a store, you need users to see whats there to offer.

The problem is that, in my home controller, i need to add middleware auth in the constructor function so that Route::get('/',HomeController@index); returns a view and in the view use @if(Auth::guest()) ..., but adding this middleware means this route is not accessible if the user is not Authenticated and without it you get this issue.

So how do i have the same root route with Authenticated user data(if authenticated) without blocking the route from unauthenticated users?

If i am understanding what you are asking (Though i believe i dont quite fully get what you mean).

You want to use the Auth::user() or Auth::check() throughout your views? This should be available out of the box especially when you have used php artisan make:auth.

One way to achieve this would be to use view->share() in a service provider on the boot method, This will then make the $user variable or $isSignedIn variable available in all views.

For example in your App\Providers\AppServiceProvider

namespace App\Providers;

use App\User;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Auth;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        view()->share('isSignedIn', Auth::check());
        view()->share('user', Auth::user() ?: new User());
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

If this is not going to help let me know and i can help towards getting the outcome you need.

- Update

On your HomeController can you try:

use App\User;
use Illuminate\Support\Facades\Auth;

and in your index() method can you add:

if(Auth::user()){
$user = Auth::user();
}else{
$user = new User();
// or you can use:
$user = Auth::guest();

// If you use $user = Auth::guest() you can remove the Use App\User;

}

return view('home', compact('user'));

See if that does anything for you?
