php - 策略始终导致 "This action is unauthorized"

Question

我试图让用户在 Laravel 8 中查看类别页面

CategoryPolicy.php

use App\Models\Category;
use App\Models\User;
use Illuminate\Auth\Access\HandlesAuthorization;

class CategoryPolicy
{
    use HandlesAuthorization;

    /**
     * Determine whether the user can view any models.
     *
     * @param User $user
     * @return mixed
     */
    public function viewAny(User $user)
    {

        return true;
    }

}

Category.php 模型

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    use HasFactory;

    protected $fillable = ['category_name','category_image', 'parent_category'];

     public function categories (): \Illuminate\Database\Eloquent\Relations\HasMany
     {
         return $this->hasMany(Category::class, 'parent_category');
     }


    public function parentCategory (): \Illuminate\Database\Eloquent\Relations\BelongsTo
    {
        return $this->belongsTo(Category::class, 'parent_category');
    }

}

在 AuthServiceProvider.php 中注册策略

    protected $policies = [
        Category::class => CategoryPolicy::class
    ];

路线

Route::group(['middleware' => 'auth'], function () {
    Route::get('/', [DashboardController::class, 'index']);
    Route::get('/admin', [DashboardController::class, 'index']);
    Route::get('/admin/categories', [CategoryController::class, 'categories'])->name('category.index');
    Route::get('/admin/get-categories', [CategoryController::class, 'allCategories'])->name('category.indexAjax');
    Route::get('/admin/get-all-categories', [CategoryController::class, 'getCategories'])->name('category.all');
    Route::post('/admin/category/new', [CategoryController::class, 'store'])->name('category.new');
    Route::delete('/admin/category/delete/{category}', [CategoryController::class, 'delete'])->name('category.delete');
});

类别 Controller

class CategoryController extends Controller
{

    public function categories(Request $request)
    {
        $this->authorize('viewAny');
        return view('admin.categories.categories');
    }

    public function getCategories(Request $request)
    {
        $categories = Category::all();
        return Response::json([
            "success" => true,
            "data" => $categories
        ]);
    }


    public function allCategories(Request $request)
    {
        return DataTables::of(Category::with('parentCategory')->get())->addIndexColumn()->make(true);
    }
}

这总是返回“403 此操作未经授权。”

我的代码应该可以工作......是的......它没有，这让我发疯。

谢谢

您应该使用授权方法发送模型

试试这个:

$this->authorize('viewAny', Category::class);
