用户授权policy

• 定义策略类

php artisan make:policy PostPolicy

app/Policies/PostPolicy.php

    public function update(User $user,Post $post){
        return $user->id === $post->user_id;
    }

    public function delete(User $user,Post $post){
        return $user->id === $post->user_id;
    }

• 注册策略类和模型关联

app/Providers/AuthServiceProvider.php

   protected $policies = [
//        'AppModel' => 'AppPoliciesModelPolicy',
        'AppPost'  => 'AppPoliciesPostPolicy'
    ];

resources/views/post/show.blade.php

@can('update',$post)
 <!-- 编辑操作 -->
@endcan

@can('delete',$post)
<!-- 删除操作 -->
@endcan

• 策略判断

$this->authorize('update',$post);
