php - isset 中的非法偏移类型或空（Laravel 7）

Question

我的 laravel 项目有一些问题。当我启动我的应用程序并在浏览器中刷新应用程序时，它会显示以下错误消息：

isset 中的非法偏移类型或空（查看：/Users/inf/open-source/application/resources/views/auth/register.blade.php）

中间件：Localization.php

<?php

namespace App\Http\Middleware;

use App;
use Closure;

class Localization
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (session()->has('locale')) {
            App::setLocale(session()->get('locale'));
        }

        return $next($request);
    }
}

控制器：本地化控制器

<?php

namespace App\Http\Controllers\Web;

use App;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request; 
use RealRashid\SweetAlert\Facades\Alert;

class LocalizationController extends Controller
{
    public function SiteLocalization($locale)
    {
        App::setLocale($locale);
        // store the locale in session so that the middleware can register it
        session()->put('locale', $locale);

        toast('The language has been changed successfully.','success');

        return redirect()->back();
    }
}

向刀片发送 $message 值

或者

例如在变量之前使用@

{{ @$message }}

或者

{{ @$message?:"default message" }}
