Question

我收到错误消息＆＃34; Class ... not found＆＃34;即使班级存在。该错误发生在yii \ web \ User类中的loginByAccessToken（）方法中。可能导致这种情况的任何想法？

public function loginByAccessToken($token, $type = null)
{
    /* @var $class IdentityInterface */
    $class = $this->identityClass;
    $identity = $class::findIdentityByAccessToken($token, $type); // <-- Error occurs here.  
    if ($identity && $this->login($identity)) {
        return $identity;
    } else {
        return null;
    }
}

以下是调试跟踪：

Answer 1

两个可能的原因。

首先如果您将应用程序从文件夹复制到另一个文件夹，或者如果您在文件夹中添加了扩展名，然后将部分代码复制到另一个文件夹中，则需要执行{{1}在最后的文件夹中。

<强>第二控制User子句使用的命名空间注意大小写。

Answer 2

更新复制的类的命名空间后。您可以在函数规则中编辑SignupForm类：

'targetClass' => '\common\models\User'

到

'targetClass' => 'app\models\User'

没有找到Yii2类
