laravel 授权、用户验证

记录帖

一、授权

只允许管理员删除用户，给管理员授权时，可以这样做，首先：

创建UserPolicy类：

php artisan make：policy UserPolicy

然后在UserPolicy中添加destroy方法

app/policies/UserPolicy.php

<?php
namespace App\Policies;
use App\Model\User;
use Illuminate\Auth\Access\HandlesAuthorization;
class UserPolicy
{
 use HandlesAuthorization;
 public function destroy(User $currentUser, User $user)
//$currentUser 为当前登录的用户，$user为需要验证的用户
{
     return $currentUser->is_admin && $currentUser->id !== $user->id;
    }
}

然后在AuthServiceProvider里添加:

\App\Model\User::class  => \App\Policies\UserPolicy::class,

app/providers/AuthServiceProvider.php

<?php
namespace App\Providers;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
class AuthServiceProvider extends ServiceProvider
{
    protected $policies = [
        'App\Model' => 'App\Policies\ModelPolicy',
        \App\Model\User::class  => \App\Policies\UserPolicy::class,
    ];
}

最后，在控制器方法中调用即可：

public function destroy(User $user)
{
 $this->authorize('destroy', $user);
    $user->delete();
    session()->flash('success', '成功删除用户！');
    return back();
}
