\Yii::$service->page->asset->register($this);

<?php $this->beginPage() ?>
<!DOCTYPE html>
<html lang="en">
<head>
</head>
以上代码可以看到在head处并没有加入
<?= Yii::$service->page->widget->render('base/head',$this); ?>
测试网页页面没有正常加载css，仅加载了JS，只有加入了head这句话才加载css，正常情况只要添加了
\Yii::$service->page->asset->register($this);
就可以正常加载吗?为什么非要
<?= Yii::$service->page->widget->render('base/head',$this); ?>
```才可以正常加载？
