(3) Use, personal test is effective

 /**

     * @describe:打包下载
     */

        if (is_array($id)){
            $ids=$id;
        }else{
            $ids=@explode(",",$id);
        }
        $data=$this->model->where('id', 'in',$ids)->select()->toArray();
        //dd($data);

        if (empty($data)) {
            $this->error("暂无数据");
        }
        $zip=new Jrk\Zipdown();
        //打包下载
         $zip->zip_file($data);
    }
