YII contoller之间的方法调用 redirect

一个contoller customercontroller里怎么调用另一个controller里的action，acontoller调用sitecontoller的actionshow($id), url显示上是customer/index

$control=yii::app()->runcontroller('site/show/id/2');  

不带参数的actionshow()

$control=yii::app()->runcontroller('site/show');  

redirect使用方法

$this->redirect(array('/site/contact','id'=>12));  

//http://www.localyii.com/testwebap/index.php?r=site/contact&id=12  

$this->redirect(array('site/contact','id'=>'idv','name'=>'namev'));  

//http://www.localyii.com/testwebap/index.php?r=site/contact&id=idv&name=namev  

$this->redirect(array('site/contact','v1','v2','v3'));  

//http://www.localyii.com/testwebap/index.php?r=site/contact&0=v1&1=v2&2=v3  

$this->redirect(array('site/contact','v1','v2','v3','#'=>'ttt'));  

//带anchor的  http://www.localyii.com/testwebap/index.php?r=site/contact&0=v1&1=v2&2=v3#ttt  

 跳转到一个绝对路径

$this->redirect('http://www.baidu.com');
