我正在嘗試創(chuàng)建一個基于拉拉維爾框架的網(wǎng)站。我被困在策略的權(quán)限控制中。這是我的代碼： + 政策 注冊于 ：App\Providers\AuthServiceProviderclass AuthServiceProvider extends ServiceProvider{    protected $policies = [        User::class => UserPolicy::class,        Category::class => CategoryPolicy::class    ];    public function boot()    {        $this->registerPolicies();        try {            Permission::all()->each(function($permission) {                Gate::define($permission->name, function ($user) use($permission) {                    return $user->hasPermission($permission->name);                });            });        } catch (\Exception $e) {            Log::notice('Unable to register gates. Either no database connection or no permissions table exists.');        }    }}用戶策略 在App\Policies\UserPolicyclass UserPolicy{    use HandlesAuthorization;    public function viewAny(User $user)    {        return true;    }    public function view(User $user, User $target_user)    {        return $user->id === $target_user->id;    }}阿皮航線routes/api.phpRoute::get('/users', 'Api\UserController@getUsers')->middleware('can:view-users');Route::get('/users/{user_id}', 'Api\UserController@getUser')->middleware('can:view-users');Route::put('/users/{user_id}', 'Api\UserController@updateUser')->middleware('can:edit-users');用戶控制器 在App\Http\Controllers\Api\UserController    public function getUsers(UserRequest $request) {        $users = $this->userRepository->getAll();        $this->authorize('view', $user);        return response($users, 200);    }    public function getUser(UserRequest $request, $user_id) {        $user = $this->userRepository->find($user_id);        $this->authorize('view', $user);        return response($user, 200);    }當(dāng)我嘗試使用上面的2 url獲取數(shù)據(jù)時，即使用戶經(jīng)過身份驗證，它也返回錯誤：500 Internal Server Error{    "error": "This action is unauthorized."}任何人都可以指出我的錯誤嗎？
