老师，我用的是advanced模板配置后台admin用户组件，但是访问url报错

Question

'admin' => [
   'class' => 'yii\web\User',
   'identityClass' => 'backend\models\Admin',
   'idParam' => '__admin',
   'enableAutoLogin' => true,
   'identityCookie' => ['name' => '__admin_identity', 'httpOnly' => true],
],

访问url报错，

Invalid Configuration – yii\base\InvalidConfigException

User::identityClass must be set.

看着没问题，看看你的Admin类

  老师，Admin类代码贴上来了

• Jason 回复 提问者 qq_鹅卵石_2 #2

  你这样，在实例化Admin的时候看看有没有部分方法没实现，逐步排查一下
