所以我正在阅读有关使用laravel策略授予权限的应用程序资源的权限,但是虽然我遵循了教程,但似乎存在问题.
我有一个无法通过HTTP请求创建的用户模型,除了具有Entrust角色“Admin”或“Broker”的其他用户.我理解并成功使其适用于索引用户等其他操作的内容如下:
在私有$policies数组中的AuthServiceProvider.php内部,我使用UserPolicy类注册了那个User类
class AuthServiceProvider extends ServiceProvider {
protected $policies = [
'App\Model' => 'App\Policies\ModelPolicy',
User::class => UserPolicy::class,
Insured::class => InsuredPolicy::class
];
public function boot(GateContract $gate)
{
$this->registerPolicies($gate);
}
}
定义UserPolicy控制器类:
class UserPolicy {
use HandlesAuthorization;
protected $user;
public function __construct(User $user) {
$this->user = $user;
}
public function index(User $user) {
$is_authorized = $user->hasRole('Admin');
return $is_authorized;
}
public function show(User $user, User $user_res) {
$is_authorized = ($user->id == $user_res->id);
return $is_authorized;
}
public function store() {
$is_authorized = $user->hasRole('Admin');
return $is_authorized;
}
}
然后在UserController类内部,在执行关键操作之前,我使用this-> authorize()检查停止或继续,具体取决于用户的权限
class UserController extends Controller
{
public function index()
{
//temporary authentication here
$users = User::all();
$this->authorize('index', User::class);
return $users;
}
public function show($id)
{
$user = User::find($id);
$this->authorize('show', $user);
return $user;
}
public function store(Request $request) {
$user = new User;
$user->name = $request->get('name');
$user->email = $request->get('email');
$user->password = \Hash::make($request->get('password'));
$this->authorize('store', User::class);
$user->save();
return $user;
}
}
问题是$this-> authorize()总是停止存储操作返回异常的进程:此操作未经授权.
我为authorize()的参数尝试了多种变体,并且不能像索引操作那样使它工作
最佳答案 在UserPolicy :: class的store()函数中,您没有传递User模型对象:
public function store(User $user) {
$is_authorized = $user->hasRole('Admin');
return true;
}
缺少参数User $user.
也许这就是问题的原因.
