        $list = json_encode($list);
        $list = json_decode($list,true);
        $temp = $list["data"];
        foreach ($temp as $k => $v){
            $temp[$k]["thumb"] = "https://upload.qudong.com/".$v["thumb"];
        }
        $list["data"] = $temp;

            return json(array("code"=>200,"msg"=>"获取成功","data"=>$list));
        }else{
            return json(array("code"=>400,"msg"=>"bad request","data"=>""));
