我在Laravel上遇到问题，无法让它登录网站上的用户。 数据库都是用预定义的用户设置的。 显示初始网页。 （不知道为什么@yield拉任何东西）

即使我在控制器中早些时候声明了类似“ auth”之类的东西，我仍然不断遇到问题。

在此方面的任何帮助将不胜感激。 我遵循了本教程，并更改了一些函数名称以匹配标准的laravel布局。 youtube.com/watch?v=OUFmvAnFclo

Controller

<?php

namespace App\Http\Controllers;

use App\Authentication;
use Illuminate\Http\Request;
use Validator;
use Auth;

class AuthController extends Controller
{
    public function index()
    {
        return view('login.auth');
    }

    public function create()
    {
        //
    }

    public function store(Request $request)
    {
        $this->validate($request,[
            'username'  =>  'required|username','password'  =>  'required|alphaNum|min:5'
        ]);

        $user_data = array(
            'username' =>  $request->get('username'),'password' =>  $request->get('password')
        );

        if(Auth::attempt($user_data)){
            return redirect('welcome');
        }
        else{
            return back()->with('error','Your details are incorrect');
        }

    }

    public function show(Authentication $authentication)
    {
        return view('welcome');
    }

    public function edit(Authentication $authentication)
    {
        //
    }

    public function update(Request $request,Authentication $authentication)
    {
        //
    }

    public function destroy(Authentication $authentication)
    {
        Auth::logout();
        return redirect('login');
    }
}

auth（查看）

@yield('heading')
@yield('login')
@yield('sign-up')
@yield('footer')

@if(isset(Auth::user()->password))
    <script>window.location="/login/success";</script>
@endif
<header><h2>Already a member?<br> Sign in here</h2></header>

<div class="container">
    @if ($message = Session::get('error'));
        <div class="alert alert-danger alert-block">
            <button type="button" class="close" data-dismiss="alert">x</button>
            <strong>{{$message}}</strong>
        </div>
    @endif
    @if(count($errors) > 0)
        <div class="alert alert-danger">
            <ul>
                @foreach($errors->all() as$error)
                    <li>{{$error}}</li>
                @endforeach
            </ul>
        </div>
    @endif
    <form method="POST" action="{{ url('/login/store") }}">
        <label for="username">username:</label>
        <input type="text" id="username" name="username" placeholder="Enter username">
        <label for="password">Password:</label>
        <input type="text" id="password" name="password" placeholder="Enter Password">
        <input type="submit" name="login" value="login">
    </form>
</div>

Welcome（查看）

@if(isset(Auth::user()->password))
  <div class="alert alert-danger success-block">
     <strong>Welcome {{ Auth::user() ->password }}</strong>
     <a href=" {{url('logout')}}">Logout</a>
  </div>
else
  <script>window.location="/login";</script>
@endif

Web.php

<?php

use Illuminate\Support\Facades\Route;

Route::get('/login','AuthController@index');
Route::post('/login/store','AuthController@store');
Route::get('login/success','AuthController@show');
Route::get('login/logout','AuthController@destroy');
