ZF1 Zend_Controller_Router_Route optional segments

我对Zend_Controller_Router_Route有一些问题。我在标准模块/控制器/操作表示法中有以下网址：

http://www.mysite.com/rent/index/region/myregion/town/mytown/district/mydistrict/filter_params/filter_values

模块：租金控制器：索引

参数：地区、城镇、地区

filter_params还有一些分页参数和向下钻取的东西

我想把它简化为：http://www.mysite.com/rent/myregion/mytown/mydistrict/filter_params/filter_values/

但这些也应该有效

http://www.mysite.com/rent/myregion/mytown/filter_params/filter_values

http://www.mysite.com/rent/myregion/filter_params/filter_values

我试过这条路线

$myRoute = new Zend_Controller_Router_Route(
    'rent/:region/:town/:district/*',
     array(
         'controller' => 'rent',
         'action' => 'index'
     )
);
$router->addRoute('rent', $myRoute);

这个工作：http://www.mysite.com/rent/myregion/mytown/mydistrict

这些失败了

http://www.mysite.com/rent/myregion/mytown

http://www.mysite.com/rent/myregion

Action 'myregion' does not exist and was not trappend in __call()

当我有类似 http://www.mysite.com/rent/myregion/mytown/filter_params/filter_values 的路由时，我如何声明其他路由以及所有其他参数会发生什么

感谢您的帮助！
