php - Yii:为什么我的 Controller 默认索引不起作用？

Question

我是个 Yiibie，遇到一个问题。我已经安装了 yii 用户和权限。每当我尝试运行 localhost/webapp/table 它都会给我错误，它会给出一个错误，即 "Error 404 The system is unable to find the requested action "list" ，但是当我尝试运行 localhost/webapp/table/index 时，它向我展示了工作正常的索引操作 View 。这是我的 config/main.php/p>

Answer 1

在 UrlManager -> rules 你可以删除这一行

'<controller:\w+>'=>'<controller>/list',

并设置 Controller 的 defaultAction 属性:

class StoryController extends RController
{
      public $defaultAction = 'list';
