添加登录中间件后，Laravel 8 验证消息未显示

问题描述

我的登录页面的验证消息工作正常，但是当我添加中间件以在访问登录页面时重定向到上一页时，如果用户已经登录。然后验证消息没有显示在我的登录页面中。

我的中间件 - SampleAuth


    public function handle(Request $request,Closure $next)
    {
       $path = $request->path();

       if($request->path()=="login" && $request->session()->has('name') )

       {

           return redirect('/');
       }
        return $next($request);
    }
}

        // \App\Http\Middleware\TrustHosts::class,\App\Http\Middleware\TrustProxies::class,\Fruitcake\Cors\HandleCors::class,\App\Http\Middleware\PreventRequestsDuringMaintenance::class,\Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,//Adding Session for middleware

<form action="/login/lp" method="POST">

                <div class="form-group">

                    <input type="text" class="form-control" id="username" name="username" value="{{ old('username') }}" aria-describedby="TextHelp" placeholder="Enter Email">

                        @foreach($errors->get('username') as $err)
                            <small class="text-danger">{{$err}}</small>
                        @endforeach
                    </div>

                </div>

                    <div class="form-group">
                    <label for="password">Password</label>
                    <input type="password" class="form-control" id="password" name="password" placeholder="Password">
                        <div>
                            @foreach($errors->get('password') as $err)
                                <small class="text-danger">{{$err}}</small>
                            @endforeach
                        </div>
                </div>

                <button type="submit" class="btn btn-primary">Login</button>
            </form>

控制器

public function postLogin($type,Request $request) {


        //Login Input Validation
        $validateData = $request->validate([
            'username' =>'required|max:45','password' =>'required|max:120'
        ]);
