Yii：为什么我的控制器默认索引不起作用？
Yii: why my default index of controller is not working?
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 时它都会给我错误，它会给出一个错误 "Error 404 The system is unable to find the requested action "list" ，但是当我尝试 运行 localhost/webapp/table/index 时它会显示视图工作正常的指数行动。这是我的 config/main.php

在你的 main.php 配置文件中，注释掉这一行：
<controller:\w+>'=>'<controller>/list
在您的 config/main.php 中，在您的 ruoting /rewrite 规则中，您已分配默认操作 = list，但 actionList 不存在于 yourController 中。然后当在 url 中设置非操作时，Yii 调用 list.php 而不是 index.php（错误 404）
你需要改变这个：
'<controller:\w+>'=>'<controller>/list',
改成这样
'<controller:\w+>'=>'<controller>/index',
或者按照@Usman Daby Khan 的建议，您可以将其删除，这样 Yii2 的默认行为就会恢复正常。
在 UrlManager -> 规则中你可以删除这一行
'<controller:\w+>'=>'<controller>/list',
并设置控制器的 defaultAction 属性：
class StoryController extends RController
{
public $defaultAction = 'list';
