(3) Use, personal test is effective
/** * @author: Hhy <jackhhy520@qq.com> * @date: 2020/7/2 0002 * @describe:打包下载 */ public function download(){ $id= $this->request->param("id"); if (is_array($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); }
