{{auth()->user()->email}/{{auth::user()->email}未在x组件中工作

php artisan make:component Navbar

• App\View\Components\Navbar.php
• app\resources\views\components\navbar.blade.php

{{ auth()->user()->email }} 或 {{ Auth::user()->email }} 在刀片文件中,出现以下错误:

• Trying to get property 'email' of non-object .

试图通过更改我的 App\View\Components\Navbar.php 致:

<?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');
    }
}

并补充说 {{ $email }} 我的刀片锉刀,它的工作。

App\View\Components\Navbar.php 致:

<?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');
    }
}
