## 接口请求的控制器 ##

<?php
    
    namespace app\api\controller;
    
    use app\api\controller\Common;
    
    use app\common\lib\exception\ApiException;
    
    
    class News extends Common
    { 
    
        /** * 获取详情接口 */
        public function read()
        { 
            // 详情页面 APP -》 1、x.com/3.html 2、 接口
            $id = input('param.id', 0, 'intval');
            if (empty($id)) { 
                return new ApiException('id is not ', 404);
            }
    
            // 通过id 去获取数据表里面的数据
            // try catch untodo
            $news = model('News')->get($id);
            if (empty($news) || $news->status != config('code.status_normal')) { 
                return new ApiException('不存在该新闻', 404);
            }
    
            //修改文章的阅读数量自加1
            try { 
                model('News')->where(['id' => $id])->setInc('read_count');
            } catch (\Exception $e) { 
                return new ApiException('error', 400);
            }
    
            $cats = config('category.category_list');
            $news->catname = $cats[$news->catid];
            return show(config('code.success'), 'OK', $news, 200);
        }
    }
