我正在从Laravel 5.2升级到5.3。除此错误外，大多数应用程序已升级。在遵循升级指南：https://laravel.com/docs/5.3/upgrade#upgrade-5.3.0时，我可以看到其中有关于防护方法的部分：
如果您正在自定义用于 身份验证，您可能需要覆盖控制器的保护措施 方法。您可以检查每个身份验证控制器的特征以 确定要覆盖的方法。
这是在发生什么事吗？我想知道为什么它抱怨一个未定义的方法。我检查了SessionGuard.php（它与Laravel一起提供，并且我完全没有修改），并且在文件的5.2或5.3版本上都没有任何handle（）方法。此外，在通过身份验证后，我可以正确浏览到某些路由，但是其他路由会抛出此错误：
