脚本宝典收集整理的这篇文章主要介绍了php artisan route :: list给我一个错误：试图获取非对象的属性，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
PHP artisan route:list
我明白了
Trying to get PRoPErty of non-object
当我输入
PHP artisan route:list -v
我明白了

这是相关的代码
public function getDefaultSettings() { $user = Auth::user(); $categorySetting = $user->settings; // <- line 31 ... }
错误消息似乎告诉我$user的错误
事情是当我dd $categorySetting或$user时,它给了我正确的对象……

}
知道什么是错的???
但是,当您从cli调用route：list时,$user为null,因此“尝试获取非对象的属性”.
您需要弄清楚的是路由：list调用getDefaultSettings()的原因.我的猜测是你在routes.PHP文件上做了一些调用该函数的东西.
解决问题的一种快速方法是使用check方法检查是否有用户在使用用户模型执行任何其他操作之前登录：
public function getDefaultSettings()
{
if (Auth::check()) {
$user = Auth::user();
$categorySetting = $user->settings;
...
}
}
