在laravel

Question

我想基本验证如果用户是管理员然后请求下一个，否则重定向到主页

  

user.php的

<?php

namespace App;

use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password','role_id','is_active','photo_id',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    public function role(){
        return $this->belongsTo('App\Role');
    }

    public function photo(){
        return $this->belongsTo('App\Photo');
    }

    public function isAdmin(){
        if ($this->role()->name=="administrator"){
            return true;
        }
        return false;
    }
}

最后一个函数是isAdmin（）

  

Admin.php （这是中间件）

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class Admin
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (Auth::check()){

            if (Auth::user()->isAdmin()){

                return $next($request);

            }
        }

        return redirect('/');
    }
}

  

routes.php文件

<?php

Route::get('/', function () {
    return view('welcome');
});


Route::get('/admin',function(){
    return view('admin.index');
});
Route::group(['middleware'=>'admin'],function(){

    Route::resource('/admin/users','AdminUsersController');

});




Route::auth();

Route::get('/home', 'HomeController@index');

**它显示我错误！**

  

Admin.php第21行中的FatalErrorException：   在null

上调用成员函数isAdmin（）

我还在kernel.php中添加了'admin' =>\App\Http\Middleware\Admin::class,并在Admin.php中导入了该类

  

PLZ ME，IAM STUCK !!!!!!!!

Answer 1

这是因为没有用户会话。中间件仅在用户登录时有效。所以你需要先登录，然后检查中间件

Answer 2

请尝试此操作：在User.php模型上将您的方法更改为 静态 。

    static function isAdmin(){
      if ($this->role()->name=="administrator"){
            return true;
       }
       return false;
    }

下一步：修改它应该工作的中间件。

  <?php

    namespace App\Http\Middleware;

    use Closure;

    class Admin
    {
        /**
         * Handle an incoming request.
         *
         * @param  \Illuminate\Http\Request  $request
         * @param  \Closure  $next
         * @return mixed
         */
        public function handle($request, Closure $next)
        {
            if (auth()->check()){

                if (\Admin::isAdmin()){

                    return $next($request);

                }
            }

            return abort(404); //redirect the user to not found page.
        }
    }
