Laravel - 致命错误：未捕获错误：未找到类'Auth'

Question

I got this Error Message:

Fatal error: Uncaught Error: Class 'Auth' not found in F:\projects\websites\main_website\app\Exceptions\Handler.php:65 Stack trace: #0 F:\projects\websites\main_website\vendor\laravel\framework\src\Illuminate\Foundation\Http\Kernel.php(326): App\Exceptions\Handler->render(Object(Illuminate\Http\Request), Object(Symfony\Component\Debug\Exception\FatalThrowableError)) #1 F:\projects\websites\main_website\vendor\laravel\framework\src\Illuminate\Foundation\Http\Kernel.php(124): Illuminate\Foundation\Http\Kernel->renderException(Object(Illuminate\Http\Request), Object(Symfony\Component\Debug\Exception\FatalThrowableError)) #2 F:\projects\websites\main_website\public\index.php(56): Illuminate\Foundation\Http\Kernel->handle(Object(Illuminate\Http\Request)) #3 {main} thrown in F:\projects\websites\main_website\app\Exceptions\Handler.php on line 65

Code its happening on:

$errorLog->error_happened_to = (Auth::check() ? Auth::user()->username : 'Guest');

Whole class:

<?php

namespace App\Exceptions;

use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;

            $errorLog->error_line = $exception->getLine();
            $errorLog->request_ip = $request->ip();
            $errorLog->request_url = $request->root();
            $errorLog->request_device = $agent->isDesktop() ? 'Desktop' : ($agent->isMobile() ? 'Mobile' : 'Tablet');

            $errorLog->save();
        }

        return parent::render($request, $exception);
    }
}

Answer 1

As I said in my earlier comment, use the full namespace in your use statement.

Replace your use Auth; with this.

use Illuminate\Support\Facades\Auth;
