{{ auth()->user()->email }} /{ Auth::user()->email }不工作于x组件

Question

php artisan make:component Navbar，创建：

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

将{{ auth()->user()->email }}或{{ Auth::user()->email }}放置在刀片文件中，会产生以下错误：

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

试图通过将我的App\View\Components\Navbar.php更改为：

<?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');
    }
}

并将{{ $email }}添加到我的刀片文件中，它起了作用。

但是，我希望显示来自经过身份验证的用户的电子邮件地址，因此我将App\View\Components\Navbar.php更改为：

<?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');
    }
}

我又犯了同样的错误。

Answer 1

由于用户未经过身份验证而出现的错误。可能在调用刀片文件中的组件之前添加一个检查，将组件包装在@auth指令之间。就像这样

@auth
    <x-navbar></x-navbar>
@endauth
