Interface yii\web\IdentityInterface

IdentityInterface is the interface that should be implemented by a class providing identity information.

This interface can typically be implemented by a user model class. For example, the following code shows how to implement this interface by a User ActiveRecord class:

class User extends ActiveRecord implements IdentityInterface
{
    public static function findIdentity($id)
    {
        return static::findOne($id);
    }

    public static function findIdentityByAccessToken($token, $type = null)
    {
        return static::findOne(['access_token' => $token]);
    }

    public function getId()
    {
        return $this->id;
    }

    public function getAuthKey()
    {
        return $this->authKey;
    }

    public function validateAuthKey($authKey)
    {
        return $this->authKey === $authKey;
    }
}
