類UserPolicy不存在（查看：F：\ XAMPP \ htdocs中\ gates_policies \資源\意見\ home.blade.php）

Question

這是我AuthServiceProvider文件，

<?php 
namespace App\Providers; 
use App\User; 
use App\Policies\UserPolicy; 
use Illuminate\Support\Facades\Gate; 
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as 
ServiceProvider; 

class AuthServiceProvider extends ServiceProvider 
{ 
/** 
* The policy mappings for the application. 
* 
* @var array 
*/ 
protected $policies = [ 
    'App\Model' => 'App\Policies\ModelPolicy', 
    User::class => UserPolicy::class, 
]; 

/** 
* Register any authentication/authorization services. 
* 
* @return void 
*/ 
public function boot() 
{ 
    $this->registerPolicies(); 

    Gate::define('display_msg','UserPolicy@display'); 
} 
} 

，在我的刀片文件我試圖顯示「Hello World」提供用戶使用Laravel中的策略有效。我的刀片文件

代碼：

@extends（ 'layouts.app'）

@section('content') 
<div class="container"> 
<div class="row"> 
    <div class="col-md-8 col-md-offset-2"> 
     <div class="panel panel-default"> 
      <div class="panel-heading">Dashboard</div> 

      <div class="panel-body"> 
       @if (session('status')) 
        <div class="alert alert-success"> 
         {{ session('status') }} 
        </div> 
       @endif 

       I am User<br> 

       @can('display_msg') 
       Hello World 
       @endcan 
      </div> 
     </div> 
    </div> 
</div> 
</div> 
@endsection 

守則UserPolicy文件：

<?php 

namespace App\Policies; 

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

class UserPolicy 
{ 
use HandlesAuthorization; 

/** 
* Create a new policy instance. 
* 
* @return void 
*/ 
public function __construct() 
{ 
    // 
} 

public function display(User $user) 
{ 
    if($user->name == 'vrajesh') 
    { 
     return true; 
    } 
    else{ 
     return false; 
    } 
} 
} 

我收到錯誤： 類UserPolicy不存在（查看：F：\ xampp \ htdocs \ gates_policies \ resources \ views \ home.blade.php）

Answer 1

嘗試改變：

Gate::define('display_msg','UserPolicy@display'); 

到：

Gate::define('display_msg','App\Policies\UserPolicy@display');
