tp5 搜索后再分页必须加入 paginate(3,false,['query'=>request()->param()]);

public function index(Request $request)
    {
        $sou = input("get.sou");
//        echo $sou;
        $list = Db('user')->where("name like '%$sou%'")->paginate(3,false,['query'=>request()->param()]);
        $page = $list->render();
        $this->assign('list', $list);
        $this->assign('page',$page);
        return $this->fetch();
}
