php - Yii 将所有操作路由到 Controller 中的一种方法

Question

我正在尝试使用 Yii 制作一个类似 cms 的应用程序。该功能将类似于:

http://www.example.com/article/some-article-name

我想做的是让所有内容都进入ArticleController.php中的方法actionIndex()，并让该方法确定如何处理该操作。所以我的问题是如何将所有操作路由到 Yii Controller 中的一个方法？

Answer 1

就您而言，我认为最好使用 filter或 beforeAction method .

过滤方式:

Filter is a piece of code that is configured to be executed before and/or after a controller action executes.

示例:

class SomeController extends Controller {
    // ... other code ...

    public function filters() {
        return array(
            // .. other filters ...
            'mysimple', // our filter will be applied to all actions in this controller
            // ... other filters ...
        );
    }

    public function filterMysimple($filterChain) { // this is the filter code
        // ... do stuff ...
        $filterChain->run(); // this bit is important to let the action run
    }

    // ... other code ...
}

beforeAction方式:

This method is invoked right before an action is to be executed (after all possible filters.) You may override this method to do last-minute preparation for the action.

示例:

class SomeController extends Controller {
    // ... other code ...

    protected function beforeAction($action) {
        if (parent::beforeAction($action)){

            // do stuff

            return true; // this line is important to let the action continue
        }
        return false;
}

    // ... other code ...
}

顺便说一句，您也可以通过以下方式访问 Controller 中的当前操作: $this->action ，以获取 id 的值:$this->action->id:

if($this->action->id == 'view') { // say you want to detect actionView
    $this->layout = 'path/to/layout'; // say you want to set a different layout for actionView 
}
