Laravel用户策略始终拒绝授权

Question

我在 Laravel 中进行了UserPolicy，并尝试在控制器中使用$this->authorize(User::class)，但是，当我访问UserController@index时它总是返回 403 错误，如果我从UserController中删除$this->authorize(User::class)，则不存在此问题

app/Providers/AuthServiceProvider.php

namespace AppProviders;
use AppTransaction;
use AppPoliciesUserPolicy;
use IlluminateSupportFacadesGate;
use IlluminateFoundationSupportProvidersAuthServiceProvider as ServiceProvider;
class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        User::class => UserPolicy::class
    ];
    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();
        //
    }
}

app/Policies/UserPolicy.php

namespace AppPolicies;
use AppUser;
use IlluminateAuthAccessHandlesAuthorization;
class UserPolicy
{
    use HandlesAuthorization;
    /**
     * Determine whether the user can index users.
     *
     * @param  AppUser  $model
     * @return mixed
     */
    public function index(User $user)
    {
        return true;
    }
}

应用程序/控制器

/用户控制器.php

namespace AppHttpControllers;
use AppUser;
use IlluminateHttpRequest;
class UserController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return IlluminateHttpResponse
     */
    public function index()
    {
        $this->authorize(User::class);
        $users = User::all();
        return view('users.index', compact('users'));
    }
}

app/Providers/AuthServiceProvider.php中缺少use AppUser;，感谢Mike Foxtech在评论中的答案

在 app/Providers/AuthServiceProvider 中.php添加 use App\User;
