controller gt nbsp

首先如果你在config/main.php里面没有配置urlManager的话,那么流程如下(摘自yii官网)

用户发出了访问 URL http://www.example.com/index.php?r=post/show&id=1 的请求,Web 服务器通过执行入口脚本index.php 处理此请求。

入口脚本创建了一个 应用 实例并执行。

应用从一个叫做 request 的 应用组件中获得了用户请求的详细信息。

应用在一个名叫 urlManager 的应用组件的帮助下,决定请求的 控制器和 动作 。在这个例子中,控制器是 post,它代表 PostController 类;动作是 show ,其实际含义由控制器决定。

应用创建了一个所请求控制器的实例以进一步处理用户请求。控制器决定了动作show 指向控制器类中的一个名为 actionShow 的方法。然后它创建并持行了与动作关联的过滤器(例如访问控制,基准测试)。如果过滤器允许,动作将被执行。

动作从数据库中读取一个 ID 为 1 的 Post 模型。

动作通过 Post 模型渲染一个名为 show 的 视图。

视图读取并显示 Post 模型的属性。

视图执行一些 小物件。

视图的渲染结果被插入一个 布局。

动作完成视图渲染并将其呈现给用户。

但是如果你已经配置了urlManager如下:

'urlManager'=>array(

            'urlFormat'=>'path',

            'rules'=>array(

                '/'=>'/index',

                '/'=>'/',

                '//'=>'/',

            ),

        ),

那么直接访问http://www.example.com/index.php?r=post/show&id=1就不可能得到show action的结果了。首先这个请求会交给defaultController的indexAction处理,defaultController在main.php里制定,如果defaultController不是PostControler,你可能就会莫名其妙了。如果正好是的话,则会返回indexAction的内容,而不是showAction。

其实要访问这个也很简单,http://www.example.com/index.php/post/show?id=1就行了

因为urlManager已经设置成按照/的形式
