yii2 rbac 的注销没有出现

Question

我安装了 yii2 2 admin，我正在制作 rbac，我遵循了一个很好的视频教程。一切正常，但只有在我的 main.php 中注销没有出现。这是我的 main.php，我该如何解决？我尝试了很多来找出我的错误，但即使我的控制器看起来还不错，但是，没有 filte，我的注销工作正常，它正在出现：

 echo Nav::widget([
        'options' => ['class' => 'navbar-nav navbar-right'],
        'items' => Helper::filter($menuItems),

    ]);

Answer 1

您正在使用 \mdm\admin\components\Helper::filter($menuItems) 删除当前用户无法访问的菜单项（这包括登录和注销操作），因此您需要为这些操作添加 rbac 例外

'as access'           => [
    'class'        => 'mdm\admin\components\AccessControl',
    'allowActions' => [
        'site/logout', // or 'site/*' if you prefer
    ]
],

或在有权访问这些路由的管理模块中创建访客角色
参见 docs 例如配置

Answer 2

尝试 $menuItems 更改

Yii::$app->user->isGuest ? (
                ['label' => 'Login', 'url' => ['/site/login']]
            ) : (
                '<li>'
                . Html::beginForm(['/site/logout'], 'post')
                . Html::submitButton(
                    'Logout (' . Yii::$app->user->identity->username . ')',
                    ['class' => 'btn btn-link logout']
                )
                . Html::endForm()
                . '</li>'
            )

在

[
            'label' => 'Login',
            'url' => ['/site/login'],
            'visible' => Yii::$app->user->isGuest,
        ],
        [
            'label' => 'Logout (' . Yii::$app->user->identity->username . ')',
            'url' => ['/site/logout'],
            'linkOptions' => ['data-method' => 'post'],
            'visible' => !Yii::$app->user->isGuest,
        ],
