Php Laravel 5.2身份验证登录有效，身份验证：：检查失败

我知道这是Laravel5.2的一个常见问题，但我已经搜索了几个小时，无法找到答案

目前，我想通过登录表单进行一个简单的身份验证调用。我正在使用一个附加到laravel AuthController的自定义数据库。我有一个表单，它发布到auth/login，并在重定向回所需路径（主页）时正确验证。但是，当我尝试在该路由上调用Auth:：check（）时，它总是返回false，就好像它是未定义的一样。现在我完全意识到必须使用“web”中间件来保存会话数据。我已经试过了，正如这里所指出的，可惜没有为我解决它。然后我意识到我使用的是laravel的5.2.32版本，这意味着我甚至不需要定义“web”中间件，因为默认情况下使用的是5.2.27版本，这表明一旦删除web中间件，就可以接收错误消息

这个问题已经折磨了我一整天，身份验证完全通过并重定向。然而，一旦我重定向，Auth就不起作用了。 如果我至少能对这段代码有一双新的眼睛，我将不胜感激

******routes.php********************************

// Route::group not necessary after version 5.2.27 of laravel on by default, simply here for display purposes.
Route::group(['middleware' => 'web'], function () {

    Route::get('/', function(){

        if(Auth::check()){
            echo "logged in";
        }

    return view('pages.home');
    }); 


    Route::get('channels/{channel}', function($channel) 
    {     
        return view('pages.channels', ['channel' => $channel] );
    });
    Route::get('events', function() 
    {    
        return view('pages.events');
    });
    Route::get('news', function() 
    {    
        return view('pages.news');
    });
    Route::get('contact', function() 
    {    
        return view('pages.contact');
    });

    // Login Form routes
    Route::get('login', function(){

        return view('pages.login');

    });

    // Just Get login working, instead of using Route::auth()
    Route::post('auth/login', 'Auth\AuthController@login');
});

*****login.blade.php**********************************我的表单

@extends('layouts.master')

@section('content')
<div class="text-center col-md-4 col-md-offset-4">
    <h1>Login</h1>

    <ul>
        @foreach($errors->all() as $error)
            <li>{{ $error }}</li>
        @endforeach
    </ul>

    {!! Form::open(array('url' => '/auth/login', 'class' => 'form')) !!}

    <div class="form-group">
        {!! Form::label('Username') !!}
        {!! Form::text('username', null, 
            array('required', 
                  'class'=>'form-control', 
                  'placeholder'=>'Your username')) !!}
    </div>

    <div class="form-group">
        {!! Form::label('Password') !!}
        {!! Form::text('password', null, 
            array('required', 
                  'class'=>'form-control', 
                  'placeholder'=>'Your password')) !!}
    </div>

    <div class="form-group">
        {!! Form::submit('Login', 
          array('class'=>'btn btn-primary')) !!}
    </div>
    {!! Form::close() !!}
    <div>
        Don't have an account? <a href="">Sign up.</a>
    </div>
</div>

*注意，我已经在config/auth.php的provider->users->model下附加了这个模型

最后是AuthController.php本身，它基本上是默认的控制器taht，与laravel一起打包。但是，loginPath、redirectPath和username变量只会更改

<?php

namespace App\Http\Controllers\Auth;

use App\New_Client;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

// temp

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

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 = '/';

    /**
    * Redirect user after failed login
    */
    protected $loginPath = '/login';

    // Override email required field with this 
    //https://stackoverflow.com/questions/28584531/modify-existing-authorization-module-email-to-username
    protected $username = 'username';

    /**
     * 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, [
            'username' => 'required|max:255',
            'password' => 'required|min:6',
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {
        return User::create([
            'username' => $data['name'],
            'password' => bcrypt($data['password']),
        ]);
    }
}

关于

所以我最终找到了解决方案，我只希望这一点没有被否决。但是，在我的模型中，我从未指明主键，因此在检索用户时，这是不可能的

要为我修复它，只需要这一行

 protected $primaryKey = 'client_idx_NW';

几年前，但工作。。。哦，我的拉威尔。。
