php artisan make:component Navbar，创建：
App\View\Components\Navbar.phpapp\resources\views\components\navbar.blade.php
放置{{ auth()->user()->email }}或{{ Auth::user()->email }}在刀片文件中，给出了这个错误：
Trying to get property 'email' of non-object.
试图通过将我的更改App\View\Components\Navbar.php为：
<?php
namespace App\View\Components;
use Illuminate\View\Component;
class Navbar extends Component
{
public $email;
/**
* Create a new component instance.
*
* @return void
*/
public function __construct($email = null)
{
$this->email = 'info@example.com';
}
/**
* Get the view / contents that represent the component.
*
* @return \Illuminate\Contracts\View\View|\Closure|string
*/
public function render()
{
return view('components.navbar');
}
}
并添加{{ $email }}到我的刀片文件中并且它有效。
但是，我想显示来自经过身份验证的用户的电子邮件地址，所以我改为App\View\Components\Navbar.php：
<?php
namespace App\View\Components;
use Illuminate\View\Component;
use Illuminate\Support\Facades\Auth;
class Navbar extends Component
{
public $email;
/**
* Create a new component instance.
*
* @return void
*/
public function __construct($email = null)
{
$this->email = Auth::user()->email;
}
/**
* Get the view / contents that represent the component.
*
* @return \Illuminate\Contracts\View\View|\Closure|string
*/
public function render()
{
return view('components.navbar');
}
}
我又遇到了同样的错误。
