/**

trait RequestActionTrait
{
/**
* Calls a controller's method from any location. Can be used to connect controllers together
* or tie plugins into a main application. requestAction can be used to return rendered views
* or fetch the return value from controller actions.
*
* Under the hood this method uses Router::reverse() to convert the $url parameter into a string
* URL. You should use URL formats that are compatible with Router::reverse()
*
* ### Examples
*
* A basic example getting the return value of the controller action:
*
* ```
* $variables = $this->requestAction('/articles/popular');
* ```
*
* A basic example of request action to fetch a rendered page without the layout.
*
* ```
* $viewHtml = $this->requestAction('/articles/popular', ['return']);
* ```
*
* You can also pass the URL as an array:
*
* ```
* $vars = $this->requestAction(['controller' => 'articles', 'action' => 'popular']);
* ```
*
* ### Passing other request data
*
* You can pass POST, GET, COOKIE and other data into the request using the appropriate keys.
* Cookies can be passed using the `cookies` key. Get parameters can be set with `query` and post
* data can be sent using the `post` key.
*
* ```
* $vars = $this->requestAction('/articles/popular', [
* 'query' => ['page' => 1],
* 'cookies' => ['remember_me' => 1],
* ]);
* ```
*
* ### Sending environment or header values
*
* By default actions dispatched with this method will use the global $_SERVER and $_ENV
* values. If you want to override those values for a request action, you can specify the values:
*
* ```
* $vars = $this->requestAction('/articles/popular', [
* 'environment' => ['CONTENT_TYPE' => 'application/json']
* ]);
* ```
*
* ### Transmitting the session
*
* By default actions dispatched with this method will use the standard session object.
* If you want a particular session instance to be used, you need to specify it.
*
* ```
* $vars = $this->requestAction('/articles/popular', [
* 'session' => new Session($someSessionConfig)
* ]);
* ```
*
* @param string|array $url String or array-based url. Unlike other url arrays in CakePHP, this
* url will not automatically handle passed arguments in the $url parameter.
* @param array $extra if array includes the key "return" it sets the autoRender to true. Can
* also be used to submit GET/POST data, and passed arguments.
* @return mixed Boolean true or false on success/failure, or contents
* of rendered action if 'return' is set in $extra.
* @deprecated 3.3.0 You should refactor your code to use View Cells instead of this method.
