控制器的开发使用说明
模块通过控制器来提供接口，控制器对于一个模块来说并不是必需的比如 察看订单的url是 http://xxx.xxx.xxx.xxx/sales/order/view/order_id/77/其中这个sales是入口的名称(frontName)，order是控制器的名字，view是action名（控制器类中的方法名），order_id参数名，77参数值对应的配置文件
1 <routers>
2 <sales>
3 <use>standard</use>
4 <args>
5 <module>Mage_Sales</module>
6 <frontName>sales</frontName>
7 </args>
8 </sales>
9 </routers>
