后端

$result=new ArrayDataProvider([
    'allModels' =>$querys,
    'pagination' => [
        'pageSize' => 10,
    ],
]);

第一页返回数据：

这个结果是因为类ArrayDataProvider的prepareModels()方法第91行，获取数据是$models = array_slice($models, $pagination->getOffset(), $pagination->getLimit(), true);，array_slice最后一个参数固定为true,所以不会重置数组的数字索引。为了json_encode的结果没有数组下标，所以需要的是将获取到当前页的数据数组的数字索引重新排列数组下标。

觉得可行的方法是，
方法1：获取到当前分页的数据之后，将当前分页的数据放到新的数组中，如：
```
$result_data = $result->getModels();
$items = array();
foreach($result_data as $row){
    array_push($items,$row);
}
echo json_encode($items);
```
方法2：使用array_merge方法重新排列数组下标
```
$items = array_merge($result->getModels());
```
