Yii2自适应切换模板

1、创建behavior

// frontend/behaviors/MobileBehavior.php
class MobileBehavior extends \yii\base\Behavior
{
public function events()
{
return [
\yii\web\Controller::EVENT_BEFORE_ACTION => 'beforeAction'
];
}
public function beforeAction($event)
{
if (strpos($_SERVER['HTTP_USER_AGENT'], 'iPhone') || strpos($_SERVER['HTTP_USER_AGENT'], 'Android') {
$event->sender->module->setViewPath($event->sender->module->getBasePath().DIRECTORY_SEPARATOR.'H5Views');
}
}
}


2、建一个基类BaseController.php

// frontend/controllers/BaseController.php
class BaseController extends \yii\web\Controller
{
public function behaviors()
{
return [
\frontend\behaviors\MobileBehavior::className()
];
}
// 其他action
}

其他控制器继承BaseController。
3、在frontend下面创建H5Views, H5模板文件放在这里面就OK了。
