【问题描述】：

我知道这是 laravel 5.2 的一个常见问题，但我一直在寻找几个小时却无法解决这个问题。

目前，我想通过登录表单进行简单的身份验证调用。我正在使用附加到 laravel AuthController 的自定义数据库。我有一个表单可以发布到 auth/login 并在它重定向回所需的路由主页时正确验证。但是，当我尝试在该路由上调用 Auth::check() 时，它总是返回 false，就好像它未定义一样。现在我完全意识到必须为我的路由使用“网络”中间件来保存会话数据。我已经尝试过，如Laravel 5.2 Auth not Working 所示，遗憾的是它并没有为我解决。然后我意识到我使用的是 laravel 的 5.2.32 版本，这意味着我什至不需要定义“web”中间件，因为它默认使用通过了 5.2.27 版本，如网络一旦接收错误消息的能力所示中间件被移除。

这个问题一直困扰着我一整天，身份验证完美通过并重定向。但是，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新的看法，那将不胜感激。

******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')) !!

************New_Client.php ************************自定义数据库模型

namespace App;

// http://laravel-recipes.com/recipes/11/changing-your-authentication-model
// model change to https://laravel.com/docs/5.0/upgrade

use Illuminate\Database\Eloquent\Model;
use Illuminate\Auth\Authenticatable;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Foundation\Auth\Access\Authorizable;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;

class New_Client extends Model implements AuthenticatableContract, AuthorizableContract, CanResetPasswordContract

    /**
     * The table associated with the model.
     *
     * @var string
     */
    protected $table = 'new_client';

    /*Turn off timestamps, as we do not have them*/
    public $timestamps = false;

    use Authenticatable, Authorizable, CanResetPassword;

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

最后是 AuthController.php 本身，它基本上是与 laravel 一起打包的默认控制器。但是 loginPath、redirectPath 和 username 变量只改变了。

<?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://***.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']),
        ]);
    

*这完全无关，但我也删除了该行 返回 $this->hasher->check($plain, $user->getAuthPassword()); 并将其替换为， return ($plain == $user->getAuthPassword()); 在 EloquentUserProvider.php 中，因为我的密码目前没有经过哈希处理，一旦测试完成就会放回去。我知道这不会影响手头的问题，但我知道为什么我不能在路由中引用 Auth

编辑：这是我们正在验证的数据库。我们有用户名、密码，甚至是文档https://laravel.com/docs/5.2/authentication#introduction-database-considerations中指出的remember_token

CREATE TABLE `new_client` (
  `client_idx_NW` int(11) NOT NULL,
  `ID` int(11) NOT NULL DEFAULT '450',
  `username` varchar(60) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
  `password` varchar(100) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,

问候

【参考方案1】：

所以我最终找到了解决方案，我只是希望这没有被否决。但是哦，好吧，在我的模型上，我从未指定主键，因此在检索用户时这是不可能的。

为我修复它只需要这条线

 protected $primaryKey = 'client_idx_NW';
