yii中的gii打不开怎么办

刚看了一下Yii，安装文档上说的，添加gii module，但是添加下面代码后，访问 index.php?r=gii 弹出登录框输入密码后不能登录，还是在index.php?r=gii/default/login页面。看请求有一个index.php?r=gii 的请求，返回302。

```
$config['bootstrap'][] = 'gii';
$config['modules']['gii'] = [
 'class' => 'yiigiiModule',
 // uncomment the following to add your IP if you are not connecting from localhost.
 'allowedIPs' => ['127.0.0.1', '::1'], //允许访问的ip是本地ip，修改为所有ip均可访问。
];
````
````
$config['bootstrap'][] = 'gii';
$config['modules']['gii'] = [
 'class' => 'yiigiiModule',
 // uncomment the following to add your IP if you are not connecting from localhost.
 'allowedIPs' => ['*', '::1'], //允许访问的ip是本地ip，修改为所有ip均可访问。
];
```
