Laravel 5.2中多用户认证支持，即同时容许不一样数据表用户（如前台用户、后台用户、app用户等）登陆认证。下面咱们就来简单介绍多用户登陆及注册功能实现。php

一、生成认证脚手架

首先咱们使用Laravel 5.2提供的认证脚手架完成初始化工做，打开终端输入：css

php artisan make:auth

该Artisan命令会生成用户认证所需的路由、视图以及HomeController：html

接着去查看路由文件routes.php，会发现该文件已经被更新：jquery

其中 Route::auth() 定义了注册登陆路由， /home 为认证经过后跳转路由。web

这里我重写了一下登陆验证的方法：ajax

Route::group(['middleware' => 'web'], function () { //Route::auth(); //前台用户
    Route::any('home/login', 'Auth\AuthController@login'); Route::get('home/logout', 'Auth\AuthController@logout'); Route::any('home/register', 'Auth\AuthController@register'); Route::get('/home', 'HomeController@index'); });

这里的Auth文件夹和类文件在 app/Http/Controllers/Auth 目录下：数据库

接着咱们打开AuthContrller.php文件，修改或添加本身的类方法，表的字段名按照数据库建立好的来填写，下面是我修改过的，你们也能够参考：bootstrap

<?php namespace App\Http\Controllers\Auth; use App\User; use Illuminate\Foundation\Auth\AuthenticatesUsers; use Validator; use App\Http\Requests; use Auth; use Redirect; use Illuminate\Http\Request; 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('guest', ['except' => 'logout']); } //登陆页面
    public function login(Request $request) { if ($request->isMethod('post')) { $validator = $this->validateLogin($request->input()); if ($validator->fails()) { return back()->withErrors($validator)->withInput(); } if (Auth::guard('web')->attempt($this->validateUser($request->input()))) { $request->session()->put('email', $request->email); return Redirect::to('home')->with('success', '登陆成功！'); }else { return back()->with('error', '帐号或密码错误')->withInput(); } } return view('auth.login'); } //登陆页面验证
    protected function validateLogin(array $data) { return Validator::make($data, [ 'email' => 'required',
            'password' => 'required', ], [ 'required' => ':attribute 为必填项',
            'min' => ':attribute 长度不符合要求' ], [ 'email' => '邮箱',
            'password' => '密码' ]); } //验证用户字段
    protected function validateUser(array $data) { return [ 'email' => $data['email'],
            'password' => $data['password'] ]; } //退出登陆
    public function logout() { if(Auth::guard('web')->user()){ Auth::guard('web')->logout(); } return Redirect::to('home'); } //注册
    public function register(Request $request) { if ($request->isMethod('post')) { $validator = $this->validateRegister($request->input()); if ($validator->fails()) { return back()->withErrors($validator)->withInput(); } $user = new User(); $user->name = $request->name;$user->email = $request->email; $user->password = bcrypt($request->password); $user->create_time = time(); $user->update_time = time(); if($user->save()){ return redirect('home/login')->with('success', '注册成功！'); }else{ return back()->with('error', '注册失败！')->withInput(); } } return view('auth.register'); } protected function validateRegister(array $data) { return Validator::make($data, [ 'name' => 'required|alpha_num|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
            'password_confirmation' => 'required|min:6|' ], [ 'required' => ':attribute 为必填项',
            'min' => ':attribute 长度不符合要求',
            'confirmed' => '两次输入的密码不一致',
            'unique' => '该邮箱已经被人占用',
            'alpha_num' => ':attribute 必须为字母或数字' ], [ 'name' => '昵称',
            'email' => '邮箱',
            'password' => '密码',
            'password_confirmation' => '确认密码' ]); } }

而后修改app目录下的 User.php：api

<?php namespace App; use Illuminate\Foundation\Auth\User as Authenticatable; class User extends Authenticatable { /** * The attributes that are mass assignable. * * @var array */
    protected $table = 'users'; //指定主键
    protected $primaryKey = 'userid'; //指定容许批量赋值的字段
    protected $fillable = [ 'name', 'email', 'password', ]; //指定不容许批量赋值的字段
     protected $guarded = []; //自动维护时间戳
    public $timestamps = false; //定制时间戳格式
    protected $dateFormat = 'U'; /** * 避免转换时间戳为时间字符串 */
    public function fromDateTime($value) { return $value; } //将默认增长时间转化为时间戳
    protected function getDateFormat() { return time(); } /** * The attributes excluded from the model's JSON form. * * @var array */
    protected $hidden = [ 'password', 'remember_token', 'app_token','email' ]; }

再去 resource/view/auth 目录下把login.balde.php 和register.blade.php 的form表单 action 分别改成 action="{{ url('home/login') }}" 和 action="{{ url('home/register') }}"，和layouts/app.blade.php 改成：浏览器

    <nav class="navbar navbar-default">
        <div class="container">
            <div class="navbar-header">

                <!-- Collapsed Hamburger -->
                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#app-navbar-collapse">
                    <span class="sr-only">Toggle Navigation</span>

                    <span class="icon-bar"></span>
                </button>

                <!-- Branding Image -->
                <a class="navbar-brand" href="{{ url('/') }}"> Laravel </a>
            </div>

            <div class="collapse navbar-collapse" id="app-navbar-collapse">
                <!-- Left Side Of Navbar -->
                <ul class="nav navbar-nav">
                    <li><a href="{{ url('/home') }}">Home</a></li>
                </ul>

                <!-- Right Side Of Navbar -->
                <ul class="nav navbar-nav navbar-right">
                    <!-- Authentication Links --> @if (Auth::guest()) <li><a href="{{ url('home/login') }}">Login</a></li>
                        <li><a href="{{ url('home/register') }}">Register</a></li> @else <li class="dropdown">
                            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false"> {{ Auth::user()->name }} <span class="caret"></span>
                            </a>

                            <ul class="dropdown-menu" role="menu">
                                <li><a href="{{ url('home/logout') }}"><i class="fa fa-btn fa-sign-out"></i>Logout</a></li>
                            </ul>
                        </li> @endif </ul>
            </div>
        </div>
    </nav> @yield('content') <!-- JavaScripts -->
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script> {{-- <script src="{{ elixir('js/app.js') }}"></script> --}} </body>
</html>

还有修改 app/Http/Middleware/Authenticate.php 文件：

<?php namespace App\Http\Middleware; use Closure; use Illuminate\Support\Facades\Auth; class Authenticate { /** * Handle an incoming request. * * @param \Illuminate\Http\Request $request * @param \Closure $next * @param string|null $guard * @return mixed */
    public function handle($request, Closure $next, $guard = null) { if (Auth::guard($guard)->guest()) { if ($request->ajax() || $request->wantsJson()) { return response('Unauthorized.', 401); } else { return redirect()->guest('home/login'); } } return $next($request); } }

二、实现前台用户登陆

接下来咱们先实现前台用户登陆，也就是Laravel自带的User用户登陆。经过上面的脚手架，咱们已经生成了认证所需的全部代码，剩下要作的就是使用迁移命令建立用户认证相关表：

php artisan migrate

该命令执行后生成 users 表和 password_resets 表，分别为用户主表和密码重置表。

而后咱们就能够在浏览器中输入 http://localhost/home 访问页面，发现页面自动跳转到了登陆页面，这里的原理就是 app/Http/Middleware/Authenticate.php 文件，如今咱们是登陆不上去了，因此咱们先点击右上角的register注册一个用户：

成功登录后就能够看到效果了：

这是前台用户登陆的效果，而后看后台登陆的实现。

三、编辑认证配置文件

要实现多用户认证，首先要配置认证配置文件，在 config 目录下的auth.php，配置以下：

<?php return [ /* |-------------------------------------------------------------------------- | Authentication Defaults |-------------------------------------------------------------------------- | | This option controls the default authentication "guard" and password | reset options for your application. You may change these defaults | as required, but they're a perfect start for most applications. | */

    'defaults' => [ 'guard' => 'web',
        'passwords' => 'users', ],

    /* |-------------------------------------------------------------------------- | Authentication Guards |-------------------------------------------------------------------------- | | Next, you may define every authentication guard for your application. | Of course, a great default configuration has been defined for you | here which uses session storage and the Eloquent user provider. | | All authentication drivers have a user provider. This defines how the | users are actually retrieved out of your database or other storage | mechanisms used by this application to persist your user's data. | | Supported: "session", "token" | */

    'guards' => [ 'web' => [ 'driver' => 'session',
            'provider' => 'users', ],

        'api' => [ 'driver' => 'token',
            'provider' => 'users', ],
        'admin' => [ 'driver' => 'session',
            'provider' => 'admins', ], ],

    /* |-------------------------------------------------------------------------- | User Providers |-------------------------------------------------------------------------- | | All authentication drivers have a user provider. This defines how the | users are actually retrieved out of your database or other storage | mechanisms used by this application to persist your user's data. | | If you have multiple user tables or models you may configure multiple | sources which represent each model / table. These sources may then | be assigned to any extra authentication guards you have defined. | | Supported: "database", "eloquent" | */

    'providers' => [ 'users' => [ 'driver' => 'eloquent',
            'model' => App\User::class, ],
        'admins' => [ 'driver' => 'eloquent',
            'model' => App\Admin::class, ],

        // 'users' => [ // 'driver' => 'database', // 'table' => 'users', // ],
    ],

    /* |-------------------------------------------------------------------------- | Resetting Passwords |-------------------------------------------------------------------------- | | Here you may set the options for resetting passwords including the view | that is your password reset e-mail. You may also set the name of the | table that maintains all of the reset tokens for your application. | | You may specify multiple password reset configurations if you have more | than one user table or model in the application and you want to have | separate password reset settings based on the specific user types. | | The expire time is the number of minutes that the reset token should be | considered valid. This security feature keeps tokens short-lived so | they have less time to be guessed. You may change this as needed. | */

    'passwords' => [ 'users' => [ 'provider' => 'users',
            'email' => 'auth.emails.password',
            'table' => 'password_resets',
            'expire' => 60, ], ], ];

认证是由 guard 和 provider 两部分构成的（参考用户认证文档），因此咱们在这两个配置项中分别新增了 admin 和 admins 选项。

四、建立后台用户模型

接下来咱们来实现后台用户登陆，首先使用以下Artisan命令生成后台用户模型：

php artisan make:model Admin --migration

带上 --migration 选项会生成对应用户表 admins ，咱们定义该数据表字段和 users 同样，生成的文件在database/migration目录下：

Schema::create('admins', function (Blueprint $table) { $table->increments('adminid'); $table->string('name'); $table->string('account_number', 128); $table->string('password', 64); $table->rememberToken(); $table->integer('create_time'); $table->integer('update_time'); });

而后经过运行迁移命令生成该表：

php artisan migrate

而后更新 Admin 模型类以下：

<?php namespace App; use Illuminate\Database\Eloquent\Model; use Illuminate\Foundation\Auth\User as Authenticatable; class Admin extends Authenticatable { //表名
    protected $table = 'admins'; //指定主键
    protected $primaryKey = 'adminid'; //指定容许批量赋值的字段
    protected $fillable = [ 'name', 'account_number', 'password', ]; //指定不容许批量赋值的字段 // protected $guarded = []; //自动维护时间戳
    public $timestamps = false; //定制时间戳格式
    protected $dateFormat = 'U'; //将默认增长时间转化为时间戳
    protected function getDateFormat() { return time(); } /** * The attributes excluded from the model's JSON form. * * @var array */
    protected $hidden = [ 'password', 'remember_token' ]; }

五、定义后台用户认证路由及控制器

接下来咱们来定义后台用户认证路由，修改 routes.php 代码以下：

Route::group(['middleware' => 'web'], function () { //Route::auth(); //前台用户
    Route::any('home/login', 'Auth\AuthController@login'); Route::get('home/logout', 'Auth\AuthController@logout'); Route::any('home/register', 'Auth\AuthController@register'); Route::get('/home', 'HomeController@index'); //后台管理员
    Route::any('admin/login', 'Admin\AuthController@login'); Route::any('admin/logout', 'Admin\AuthController@logout'); Route::any('admin/register', 'Admin\AuthController@register'); Route::get('/admin', 'AdminController@index'); });

而后使用Artisan命令建立对应控制器：

php artisan make:controller Admin/AuthController php artisan make:controller AdminController
php artisan make:middleware AuthAdmin

app/Http 目录下会多出Admin认证的文件夹和AdminController.php文件，修改AdminController.php：

<?php namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Http\Requests; class AdminController extends Controller { /** * Create a new controller instance. * * @return void */
    public function __construct() { $this->middleware('admin'); } /** * Show the application dashboard. * * @return \Illuminate\Http\Response */
    public function index() { return view('admin.index'); } }

编辑 Admin/AuthController.php 代码以下：

<?php namespace App\Http\Controllers\Admin; use App\Admin; use Illuminate\Foundation\Auth\AuthenticatesUsers; use Validator; use App\Http\Requests; use Auth; use Redirect; use Illuminate\Http\Request; use App\Http\Controllers\Controller; use Illuminate\Foundation\Auth\ThrottlesLogins; use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers; class AuthController extends Controller { use AuthenticatesAndRegistersUsers, ThrottlesLogins; // protected $redirectTo = 'admin'; // protected $guard = 'admin'; // protected $loginView = 'admin.login'; // protected $registerView = 'admin.register';

    public function __construct() { $this->middleware('guest:admin', ['except' => 'logout']); } //登陆
    public function login(Request $request) { if ($request->isMethod('post')) { $validator = $this->validateLogin($request->input()); if ($validator->fails()) { return back()->withErrors($validator)->withInput(); } if (Auth::guard('admin')->attempt(['account_number'=>$request->account_number, 'password'=>$request->password])) { return Redirect::to('admin')->with('success', '登陆成功！');     //login success, redirect to admin
            } else { return back()->with('error', '帐号或密码错误')->withInput(); } } return view('admin.login'); } //登陆页面验证
    protected function validateLogin(array $data) { return Validator::make($data, [ 'account_number' => 'required|alpha_num',
            'password' => 'required', ], [ 'required' => ':attribute 为必填项',
            'min' => ':attribute 长度不符合要求' ], [ 'account_number' => '帐号',
            'password' => '密码' ]); } //退出登陆
    public function logout() { if(Auth::guard('admin')->user()){ Auth::guard('admin')->logout(); } return Redirect::to('admin/login'); } //注册
    public function register(Request $request) { if ($request->isMethod('post')) { $validator = $this->validateRegister($request->input()); if ($validator->fails()) { return back()->withErrors($validator)->withInput(); } $user = new Admin(); $user->name = $request->name; $user->account_number = $request->account_number; $user->password = bcrypt($request->password); $user->create_time = time(); $user->update_time = time(); if($user->save()){ return redirect('admin/login')->with('success', '注册成功！'); }else{ return back()->with('error', '注册失败！')->withInput(); } } return view('admin.register'); } protected function validateRegister(array $data) { return Validator::make($data, [ 'name' => 'required|alpha_num|max:255',
            'account_number' => 'required|alpha_num|unique:admins',
            'password' => 'required|min:6|confirmed',
            'password_confirmation' => 'required|min:6|' ], [ 'required' => ':attribute 为必填项',
            'min' => ':attribute 长度不符合要求',
            'confirmed' => '两次输入的密码不一致',
            'unique' => '该帐户已存在',
            'alpha_num' => ':attribute 必须为字母或数字',
            'max' => ':attribute 长度过长' ], [ 'name' => '昵称',
            'account_number' => '帐号',
            'password' => '密码',
            'password_confirmation' => '确认密码' ]); } }

编辑 Middleware/AuthAdmin.php 代码以下：

<?php namespace App\Http\Middleware; use Closure; use Illuminate\Support\Facades\Auth; class AuthAdmin { /** * Handle an incoming request. * * @param \Illuminate\Http\Request $request * @param \Closure $next * @param string|null $guard * @return mixed */
    public function handle($request, Closure $next, $guard = null) { if (Auth::guard('admin')->guest()) { if ($request->ajax() || $request->wantsJson()) { return response('Unauthorized.', 401); } else { return redirect()->guest('admin/login'); } } return $next($request); } }

最后再修改Http/Kernel.php，最下方添加一个 admin 认证用户指向：

protected $routeMiddleware = [ 'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'admin' => \App\Http\Middleware\AuthAdmin::class, ];

六、视图文件建立及修改

最后咱们要建立后台用户认证对应视图文件，这里咱们简单拷贝前台用户视图模板并稍做修改便可：

cp -r resources/views/auth resources/views/admin

修改 resources/views/admin 目录下登陆及注册表单提交地址：

@extends('layouts.admin')

@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('admin/login') }}">
                        {!! csrf_field() !!}

                        <div class="form-group{{ $errors->has('account_number') ? ' has-error' : '' }}">
                            <label class="col-md-4 control-label">Account Number</label>

                            <div class="col-md-6">
                                <input type="text" class="form-control" name="account_number" value="{{ old('account_number') }}">

                                @if ($errors->has('account_number'))
                                    <span class="help-block">
                                        <strong>{{ $errors->first('account_number') }}</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">

再把 home.blade.php 复制到admin下，重名为index.php，app.blade.php 复制一个并重命名为admin.ablde.php：

cp /resources/views/home.blade.php /resources/views/index.blade.php

cp /resources/views/layouts/app.blade.php /resources/views/layouts/admin.blade.php

admin.blade.php 修改以下：
