我正在建立一个Laravel电子商务网站，我似乎在登录页面上遇到了困难。当我运行/auth/login时，我得到以下错误消息：
331b09d5d39f256b356d4ae58180ae01edf5c37.php第12行出现错误异常：未定义变量：错误（视图：/home/thomas/ushop/resources/views/auth/login.blade.php）

这让我很困惑，因为我使用的是开箱即用的Laravel用户系统。这可能是因为还没有创建表单错误吗？
编辑这是我的代码：
@extends('vendor.app')
@section('content')
<div class="container">
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
<div class="panel-heading">Login</div>
<div class="panel-body">
<form class="form-horizontal" role="form" method="POST" action="{{ url('/login') }}">
{!! csrf_field() !!}
<div class="form-group{{ $errors->has('email') ? ' has-error' : '' }}">
<label class="col-md-4 control-label">E-Mail Address</label>
<div class="col-md-6">
<input type="email" class="form-control" name="email" value="{{ old('email') }}">
@if ($errors->has('email'))
<span class="help-block">
<strong>{{ $errors->first('email') }}</strong>
</span>
@endif
</div>
</div>
<div class="form-group{{ $errors->has('password') ? ' has-error' : '' }}">
<label class="col-md-4 control-label">Password</label>
<div class="col-md-6">
<input type="password" class="form-control" name="password">
@if ($errors->has('password'))
<span class="help-block">
<strong>{{ $errors->first('password') }}</strong>
</span>
@endif
</div>
</div>
<div class="form-group">
<div class="col-md-6 col-md-offset-4">
<div class="checkbox">
<label>
<input type="checkbox" name="remember"> Remember Me
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-md-6 col-md-offset-4">
<button type="submit" class="btn btn-primary">
<i class="fa fa-btn fa-sign-in"></i>Login
</button>
<a class="btn btn-link" href="{{ url('/password/reset') }}">Forgot Your Password?</a>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>

编辑2：我的控制器代码，尽管这是Laravel的开箱即用代码，因为它是默认的
<?php
namespace App'Http'Controllers'Auth;
use App'User;
use Validator;
use App'Http'Controllers'Controller;
use Illuminate'Foundation'Auth'ThrottlesLogins;
use Illuminate'Foundation'Auth'AuthenticatesAndRegistersUsers;
class AuthController extends Controller
{
/*
|--------------------------------------------------------------------------
| Registration & Login Controller
|--------------------------------------------------------------------------
|
| This controller handles the registration of new users, as well as the
| authentication of existing users. By default, this controller uses
| a simple trait to add these behaviors. Why don't you explore it?
|
*/
use AuthenticatesAndRegistersUsers, ThrottlesLogins;
/**
* Where to redirect users after login / registration.
*
* @var string
*/
protected $redirectTo = '/';
/**
* Create a new authentication controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware($this->guestMiddleware(), ['except' => 'logout']);
}
/**
* Get a validator for an incoming registration request.
*
* @param array $data
* @return 'Illuminate'Contracts'Validation'Validator
*/
protected function validator(array $data)
{
return Validator::make($data, [
'name' => 'required|max:255',
'email' => 'required|email|max:255|unique:users',
'password' => 'required|min:6|confirmed',
]);
}
/**
* Create a new user instance after a valid registration.
*
* @param array $data
* @return User
*/
protected function create(array $data)
{
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
]);
}
}
此错误是因为您没有将errors变量设置为视图，在控制器上您必须
return view('auth', ['errors' => $erros]);
