首先你要创建一个模型kmModel

$query = Km1::find();
 $dataProvider = new ActiveDataProvider([
     'query' => $query,
     'sort' =>[
         'defaultOrder'=>['created' => SORT_DESC],
      ],
      'pagination' => [
           'page' => $this->page - 1, // oh, shit. this is zero-base
           'pageSize' => $this->pagesize,
       ],
 ])
 $query->select($this->getSelectFields())
     ->andFilterWhere([条件]);
 return $dataProvider;

  控制器里这么写：
   $kmModel = new kmModel;
   $dataProvider = $kmModel->search();
   if (empty($dataProvider->getModels())) {
        return '无查询结果';
   }
