导读：当我输入 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 Exception trace: () at /home/vagrant/Code/app/CategorySettings.php:31 IlluminateFoundationBootstrapHandleException

当我输入

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……

User {#418 ▼
  #table: "users"
  #fillable: array:16 [?]
  #hidden: array:2 [?]
  #connection: null
  #primaryKey: "id"
  #perPage: 15
  +incrementing: true
  +timestamps: true
  #attributes: array:20 [?]
  #original: array:20 [?]
  #relations: array:1 [?]
  #visible: []
  #appends: []
  #guarded: array:1 [?]

  #dateFormat: null
  #casts: []
  #touches: []
  #observables: []
  #with: []
  #morphClass: null
  +exists: true
  +wasRecentlyCreated: false
}

知道什么是错的???

解决方法

Auth :: user()仅在用户登录时返回User模型,因此当您在浏览器上dd时,将返回您的用户.

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;
    ...
    }
}
