requestAction(string $url, array $options)
This function calls a controller's action from any location and returns data from the action. The $url passed is a CakePHP-relative URL (/controllername/actionname/params). To pass extra data to the receiving controller action add to the $options array.
You can use requestAction() to retrieve a fully rendered view by passing 'return' in the options: requestAction($url, array('return'));. It is important to note that making a requestAction using 'return' from a controller method can cause script and css tags to not work correctly.
If used without caching requestAction can lead to poor performance. It is rarely appropriate to use in a controller or model.
requestAction is best used in conjunction with (cached) elements – as a way to fetch data for an element before rendering. Let's use the example of putting a "latest comments" element in the layout. First we need to create a controller function that will return the data.
When an action is called through requestAction $this->params['requested'] is set to 1 as an indicator. So checking that you can either return the required data else set it a view variable like you normally would. This helps keep things DRY.
例子：
在air_status控制器中调用stores_houses的方法shlistdir
function airscene()
{
$this->layout = "iframe";
$rs = $this->requestAction('/stores_houses/shlistdir');
$this->set('test',$rs);
}
