{{ auth()->user()->email }} / {{ Auth::user()->email }} 在 x-component 中不起作用

Question

php artisan make:component Navbar，创建时间：

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

在 blade 文件中放置 {{ auth()->user()->email }} 或 {{ Auth::user()->email }}，给出了这个错误：

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

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

来解决此问题

<?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 blade 文件中，它起作用了。

但是，我想显示已验证用户的电子邮件地址，所以我将 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');
    }
}

我又遇到了同样的错误。

Answer 1

您遇到的错误是因为用户未通过身份验证。也许在调用 blade 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。像这样

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

{{ auth()->user()->email }} / {{ Auth::user()->email }} 在 x-component 中不起作用

{{ auth()->user()->email }} / {{ Auth::user()->email }} not working in x-component
