如何在Zend Framework中检索url参数？

Question

我试图使用zend框架检索在url中传递的参数.但当然,它不起作用!我的代码看起来像这样:

生成网址:

<?php echo $this->url(array('controller' => 'poll', 'action' => 'showresults', 'poll_id' => $poll['_id']), null, true) ?>

检索showresultsAction()中的"poll_id"参数:

 $request = new Zend_Controller_Request_Http();
 $poll_id = $request->getParam('poll_id');

问题是$ poll_id是NULL.当我执行$ request-> getParams()的var_dump时,它也是NULL.我已经浏览了Zend Framework文档,但它并不是很有用.任何的想法 ？谢谢 !

代替:

$request = new Zend_Controller_Request_Http();
$poll_id = $request->getParam('poll_id');

尝试:

$request = $this->getRequest(); //$this should refer to a controller
$poll_id = $request->getParam('poll_id');

要么:

$poll_id = $this->_getParam('poll_id'); //$this should refer to a controller

Zend Framework自动将请求对象附加到控制器.
