public function process(Zend_Controller_Request_Abstract $request)
{
$this->first_name = $this->sanitize($request->getPost('first_name'));
....
}
我的问题是$request类的实例zend_controller_request_abstract,但是getpost是在类zend_controller_request_http中定义的函数,它扩展了zend_controller_request_abstract,为什么直接$request调用getPost()？
