Laravel登录&使用错误代码注册

Laravel Login & Registration with Error Code

当检测到无效的登录电子邮件或密码时，希望返回错误消息.

Would like to have an error message returned when an invalid login email or password is detected..

我想到的是要有一个控制器来触发错误消息显示在login.php上.推荐吗?

What was on my mind was to have a controller to trigger the error message to appear on the login.php. is it recommended?

中间件/身份验证

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Contracts\Auth\Guard;

class Authenticate
{
/**
 * The Guard implementation.
 *
 * @var Guard
 */
protected $auth;

/**
 * Create a new filter instance.
 *
 * @param  Guard  $auth
 * @return void
 */
public function __construct(Guard $auth)
{
    $this->auth = $auth;
}

/**
 * Handle an incoming request.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Closure  $next
 * @return mixed
 */
public function handle($request, Closure $next)
{
    if ($this->auth->guest()) {
        if ($request->ajax()) {
            return response('Unauthorized.', 401);
        } else {
            return redirect()->guest('login');
        }
    }




    return $next($request);
}
}

推荐答案

您可以使用它来循环错误

You can use this to loop errors

@if(count($errors) > 0)
         <div class="alert alert-danger">
            <strong>Whoops!</strong> There were some problems with your input.<br><br>
            <ul>
                @foreach ($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
         </div>
    @endif
