如何修复登录页面 Laravel ui auth 在错误输入时没有显示任何错误消息 email/password

Question

我在 Laravel 8 中构建了项目并且上面有登录页面，但是我遇到了问题，当用户输入错误的密码或电子邮件时，登录页面没有显示任何错误消息。这是我的登录控制器

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;

class LoginController extends Controller
{
  

    use AuthenticatesUsers;


    protected $redirectTo = RouteServiceProvider::HOME;


    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }
    public function login(Request $request)
    {
        $input = $request->all();

        $this->validate($request, [
            'email' => 'required|email',
            'password' => 'required',
           
        ]);

        if (auth()->attempt(array('email' => $input['email'], 'password' => $input['password']))) {
            if (auth()->user()) {
                return redirect()->route('home.index');
            }
        } else {
            return redirect()->route('login')
                ->with('error', 'Email-Address And Password Are Wrong.');
        }
    }
}

这是我的登录视图

@extends('layouts.pre')

@section('content')
<div class="container">
    <div class=" row justify-content-center">
        <div class=" col-md-6">
            <div class=" card ">


                <div class="card-body">
                    <h3 style="margin-bottom: 5%" class="text-center">Login</h3><br>
                    <form method="POST" action="{{ route('login') }}">
                        @csrf

                        <div class="form-group row">
                            <label for="email" class="col-md-4 col-form-label text-md-right">{{ __('E-Mail Address') }}</label>

                            <div class="col-md-6">
                                <input id="email" placeholder="Email" type="email" class="form-control @error('email') is-invalid @enderror" name="email" value="{{ old('email') }}" required autocomplete="email" autofocus>

                                @error('email')
                                <span class="invalid-feedback" role="alert">
                                    <strong>{{ $message }}</strong>
                                </span>
                                @enderror
                            </div>
                        </div>

                                @error('password')
                                <span class="invalid-feedback" role="alert">
                                    <strong>{{ $message }}</strong>

您可以使用 Session 获取 blade 模板中的错误：

@if(Session::has('error'))
<div class="alert alert-danger">
  {{ Session::get('error')}}
</div>
@endif
