示例代码
Yii::$app->request->get('id')
* @var string
*/
public $varByParam = '';
public function beforeAction($action)
{
if (!$this->enabled) {
return true;
}
$this->cache = Instance::ensure($this->cache, Cache::className());
if (is_array($this->dependency)) {
$this->dependency = Yii::createObject($this->dependency);
}
$properties = [];
foreach (['cache', 'duration', 'dependency', 'variations'] as $name) {
$properties[$name] = $this->$name;
}
$id = $this->varyByRoute ? $action->getUniqueId().$this->varByParam : __CLASS__;
$response = Yii::$app->getResponse();
ob_start();
ob_implicit_flush(false);
if ($this->view->beginCache($id, $properties)) {
$response->on(Response::EVENT_AFTER_SEND, [$this, 'cacheResponse']);
return true;
} else {
$data = $this->cache->get($this->calculateCacheKey());
if (is_array($data)) {
$this->restoreResponse($response, $data);
}
$response->content = ob_get_clean();
return false;
}
}
}
?>使用:
[
'class' => 'common\lib\PageCache',
'only' => ['view'],
'duration' => 0, //永不过期
'varByParam' => Yii::$app->request->get('id'),
],
