Laravel 5.2: 如何在中间件中使用auth

Question

我创建了一个名为 Adminpanel 的新中间件

namespace App\Http\Middleware;

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

class Adminpanel
{
    public function handle($request, Closure $next)
    {
        if(Auth::user()->role == 'admin'){
            return $next($request);
        }else{
            return redirect('admin/login');
        }
    }
}

并注册中间件

protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    'adminpanel' => \App\Http\Middleware\Adminpanel::class,
];

和路线

Route::group(['middleware' => ['web','adminpanel']], function () {
Route::get('/admin/dashboard/', 'admin\Dashboard@index');
//

});

但是当我运行时，它问我 Trying to get 属性 of non-object，这意味着我无法在此处访问 Auth class，有人可以告诉我什么是错误以及如何在中间件中访问 Auth Facade。

这是我的验证码

public function authenticate(Request $request)
{
    if (Auth::attempt(['email' => $request->input('email'), 'password' => $request->input('password'), 'role' => 'admin'], $request->input('remember'))) 
    {
        return redirect()->intended('admin/dashboard');
    }
    else{
        return redirect('admin')->with('response',-1);
    }
}

谢谢

这并不意味着您无法访问 Auth class。这意味着，该用户未通过身份验证 Auth::user() returns NULL.

通过为该路由使用 auth 中间件，确保只有经过身份验证的用户才能访问您的路由，或者首先检查用户是否已通过身份验证：

if(Auth::check() && Auth::user()->role == 'admin'){
  return $next($request);
} else {
  return redirect('admin/login');
}
