• laravel中的plicy授权方法:


    1.用命令新建policy:

    php artisan make:policy PostPolicy
    

      

    2.在app/Policies/PostPolicy.php中添加处理文件的权限的方法:

    //修改:
        public function update(User $user, Post $post)
        {
            return $user->id == $post->user_id;
        }
        //删除权限:
        public function delete(User $user, Post $post)
        {
            return $user->id == $post->user_id;
        }
    

      

    控制器中,添加权限限制:

    //更新文章:
        public function update(Post $post)
        {
            //验证:
            $this->validate(request(), [
                'title' => 'required|string|max:100|min:10',
                'content' => 'required|string|min:4'
            ]);
            $this->authorize('update', $post);
            //逻辑:
            $post->title = 
    equest('title');
            $post->content = 
    equest('content');
            $post->save();
            return redirect("/posts/{$post->id}");
        }
    
        //删除逻辑:
        public function delete(Post $post)
        {
            $this->authorize('delete', $post); 
        //TODD 用户的权限验证:
        $post->delete();
        return redirect("/posts");
      }

      

    在视图中,对授权的使用:

    <div style="display:inline-flex">
       <h2 class="blog-post-title">{{$post->title}}</h2>
       @can('update',$post)
            <a style="margin: auto" href="/posts/{{$post->id}}/edit">
              <span class="glyphicon glyphicon-pencil" aria-hidden="true"></span>
            </a>
       @endcan
       @can('delete',$post)
           <a style="margin: auto" href="{{url('/posts/'.$post->id.'/delete')}}">
             <span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
           </a>
       @endcan
    </div>
