Php Laravel 5.6身份验证登录页面错误未显示刀片服务器

我正在学习Laravel5，我已经为用户登录编写了以下代码。我没有在LoginController.php文件中使用sendFailedLoginResponse函数。现在，我尝试使用以下代码显示验证错误消息：

@if($errors->any())
     <div class="alert alert-danger">
           <ul>
               @foreach ($errors->all() as $error)
                     <li>{{ $error }}</li>
                @endforeach
            </ul>
      </div>
@endif

login.blade.php表单

<form id="loginForm" method="post" action="{{ url('login') }}" class="login-form">
    {!! csrf_field() !!}
    <div class="form-group form-group-username">
        <label for="login-form-username">E-MAIL</label>
        <input type="text" id="email" name="email" class="form-control" required="required" placeholder="E-mail adresinizi girin">
    </div>
    <!-- /.form-group -->
    <div class="form-group form-group-password">
        <label for="login-form-password">ŞİFRE</label>
        <input id="password" type="password" name="password" class="form-control" autocomplete="off" required="required" placeholder="Lütfen şifrenizi girin">
    </div>
    <!-- /.form-group -->
    <div class="form-group form-group-button">
        <button type="submit" id="loginSend" class="button">Oturum Aç</button>
    </div>
    <!-- /.form-group -->
    <div class="login-form-reset-link">
        <a href="http://segments-demo.wearecodevision.com/reset-password/">Şifrenizi mi unuttunuz?</a>
    </div>
    <!-- /.login-form-reset-link -->
</form>

我也面临同样的问题。在到处挖掘之后，我通过从app\http\kernel.php中的'web'的$Middleware组中删除\illumb\Session\Middleware\StartSession:：class解决了这个问题

protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class, // <-- Remove this
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

        'api' => [
            'throttle:60,1',
            'bindings',
        ],
    ];

受保护的$middlewareGroups=[
“网络”=>[
\App\Http\Middleware\EncryptCookies:：class，
\Illumb\Cookie\Middleware\AddQueuedCookiesToResponse:：class，
\Illumb\Session\Middleware\StartSession:：class，//[
'节气门：60,1'，
“绑定”，
],
];

error->all（）设置的确切位置在哪里？查看/auth/login.blade.php只有在flash警报工作时才能尝试此操作：

@if（$errors->has（'email'））{{$errors->first（'email'）}@endif

否，不工作尝试登录时，应用程序实际做了什么？重新加载还是什么？

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
    \App\Http\Middleware\TrimStrings::class,
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    \App\Http\Middleware\TrustProxies::class,
    \App\Http\Middleware\EncryptCookies::class,
    \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    \App\Http\Middleware\VerifyCsrfToken::class,
];

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        // \Illuminate\Session\Middleware\AuthenticateSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ],

    'api' => [
        'throttle:60,1',
        'bindings',
    ],
];

protected $middlewareGroups = [
        'web' => [

            \Illuminate\Session\Middleware\StartSession::class, // <-- Remove this
