Laravel 5.5 不同用户表登录认证(前后台分离)
Auth 认证原理简述
Laravel 的认证是使用 guard
与 provider
配合完成, guard
负责认证的业务逻辑,认证信息的服务端保存等; provider
负责提供认证信息的持久化数据提供。
请求提交给 guard
, guard
从 provider
里取出数据(类似用户名、密码等),验证输入数据与服务器端存储的数据是否吻合。如果提交的数据正确,再做 session 等业务的处理(如有需要)。
认证脚手架
首先我们导入 Laravel 的自带的认证脚手架
php artisan make:auth
执行数据库迁移:
php artisan migrate
修改 Auth 认证的配置文件 config/auth.php
在 gurads 处,添加 admin
guard 用于后台管理员认证
'guards' => [ 'web' => [ 'driver' => 'session', 'provider' => 'users', ], 'admin' => [ 'driver' => 'session', 'provider' => 'admins', ], 'api' => [ 'driver' => 'token', 'provider' => 'users', ], ],
在 providers 处添加 admins
provider,使用 Admin
模型
'providers' => [ 'users' => [ 'driver' => 'eloquent', 'model' => App\User::class, ], 'admins' => [ 'driver' => 'eloquent', 'model' => App\Admin::class, ], ],
创建后台管理员模型
我们再创建一个 Admin
模型,用于后台管理员登录验证。
php artisan make:model Admin -m
-m 参数会同时生成数据库迁移文件 xxxx_create_admins_table
修改 app/Admin.php
模型文件
<?php namespace App; use Illuminate\Notifications\Notifiable; use Illuminate\Foundation\Auth\User as Authenticatable; class Admin extends Authenticatable { use Notifiable; /** * The attributes that are mass assignable. * * @var array */ protected $fillable = [ 'name', 'password', ]; /** * The attributes that should be hidden for arrays. * * @var array */ protected $hidden = [ 'password', 'remember_token', ]; }
编辑 xxxx_create_admins_table
文件,后台管理员模型结构与前台用户差不多,去掉 email
字段,name
字段设为 unique
<?php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class CreateAdminsTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create('admins', function (Blueprint $table) { $table->increments('id'); $table->string('name')->unique(); $table->string('password'); $table->rememberToken(); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists('admins'); } }
管理员模型填充数据
定义一个数据模型工厂,在 database/factories/ModelFactory.php
中添加如下代码
$factory->define(App\Admin::class, function (Faker\Generator $faker) { static $password; return [ 'name' => $faker->firstName, 'password' => $password ?: $password = bcrypt('secret'), 'remember_token' => str_random(10), ]; });
使用 Faker
随机填充用户名
在 database/seeds
目录下生成 AdminsTableSeeder.php
文件。
php artisan make:seeder AdminsTableSeeder
编辑 database/seeds/AdminsTableSeeder.php
文件的 run
方法,添加3个管理员用户,密码为 123456
1 public function run() 2 { 3 factory('App\Admin', 3)->create([ 4 'password' => bcrypt('123456') 5 ]); 6 }
在 database/seeds/DatabaseSeeder.php
的 run
方法里调用 AdminsTableSeeder
类
1 public function run() 2 { 3 $this->call(AdminsTableSeeder::class); 4 }
执行数据库迁移命令
1 php artisan migrate --seed
数据库里会创建 admins 表,并且生成了3条数据
创建后台页面
创建控制器
php artisan make:controller Admin/LoginController php artisan make:controller Admin/IndexController
其中, Admin/LoginController
负责登录逻辑; Admin/IndexController
管理登录后的首页。
编辑 Admin/LoginController.php
<?php namespace App\Http\Controllers\Admin; use App\Http\Controllers\Controller; use Illuminate\Foundation\Auth\AuthenticatesUsers; class LoginController extends Controller { /* |-------------------------------------------------------------------------- | Login Controller |-------------------------------------------------------------------------- | | This controller handles authenticating users for the application and | redirecting them to your home screen. The controller uses a trait | to conveniently provide its functionality to your applications. | */ use AuthenticatesUsers; /** * Where to redirect users after login / registration. * * @var string */ protected $redirectTo = '/admin'; /** * Create a new controller instance. * * @return void */ public function __construct() { $this->middleware('guest.admin', ['except' => 'logout']); } /** * 显示后台登录模板 */ public function showLoginForm() { return view('admin.login'); } /** * 使用 admin guard */ protected function guard() { return auth()->guard('admin'); } /** * 重写验证时使用的用户名字段 */ public function username() { return 'name'; } }
编辑 Admin/IndexController.php
<?php namespace App\Http\Controllers\Admin; use Illuminate\Http\Request; use App\Http\Requests; use App\Http\Controllers\Controller; class IndexController extends Controller { /** * 显示后台管理模板首页 */ public function index() { return view('admin.index'); } }
后台显示模板
复制 views/layouts/app.blade.php
成 views/layouts/admin.blade.php
编辑后台管理布局模板
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <!-- CSRF Token --> <meta name="csrf-token" content="{{ csrf_token() }}"> <title>{{ config('app.name', 'Laravel') }} - Admin</title> <!-- Styles --> <link href="{{ asset('css/app.css') }}" rel="stylesheet"> </head> <body> <nav class="navbar navbar-default navbar-static-top"> <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> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <!-- Branding Image --> <a class="navbar-brand" href="{{ url('/') }}"> {{ config('app.name', 'Laravel') }} </a> </div> <div class="collapse navbar-collapse" id="app-navbar-collapse"> <!-- Left Side Of Navbar --> <ul class="nav navbar-nav"> </ul> <!-- Right Side Of Navbar --> <ul class="nav navbar-nav navbar-right"> <!-- Authentication Links --> @if (auth()->guard('admin')->guest()) <li><a href="{{ url('/admin/login') }}">Login</a></li> {{--<li><a href="{{ route('register') }}">Register</a></li>--}} @else <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false" aria-haspopup="true"> {{ auth()->guard('admin')->user()->name }} <span class="caret"></span> </a> <ul class="dropdown-menu"> <li> <a href="{{ url('/admin/logout')}}" onclick="event.preventDefault(); document.getElementById('logout-form').submit();"> Logout </a> <form id="logout-form" action="{{ url('/admin/logout')}}" method="POST" style="display: none;"> {{ csrf_field() }} </form> </li> </ul> </li> @endif </ul> </div> </div> </nav> @yield('content') <!-- Scripts --> <script src="{{ asset('js/app.js') }}"></script> </body> </html>
复制 views/auth/login.blade.php
成 views/admin/login.blade.php
编辑该模板,更改布局文件为 layouts.admin, 把表单的提交 url 改为 admin/login
,email 字段改成 name字段,去掉找回密码的部分
@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">Admin Login</div> <div class="panel-body"> <form class="form-horizontal" role="form" method="POST" action="{{ url('/admin/login') }}"> {{ csrf_field() }} <div class="form-group{{ $errors->has('name') ? ' has-error' : '' }}"> <label for="name" class="col-md-4 control-label">Name</label> <div class="col-md-6"> <input id="name" type="text" class="form-control" name="name" value="{{ old('name') }}" required autofocus> @if ($errors->has('name')) <span class="help-block"> <strong>{{ $errors->first('name') }}</strong> </span> @endif </div> </div> <div class="form-group{{ $errors->has('password') ? ' has-error' : '' }}"> <label for="password" class="col-md-4 control-label">Password</label> <div class="col-md-6"> <input id="password" type="password" class="form-control" name="password" required> @if ($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-8 col-md-offset-4"> <button type="submit" class="btn btn-primary"> Login </button> </div> </div> </form> </div> </div> </div> </div> </div> @endsection
复制 views/home.blade.php
成 views/admin/index.blade.php
编辑该模板
@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">Dashboard</div> <div class="panel-body"> You are logged in admin dashboard! </div> </div> </div> </div> </div> @endsection
添加后台路由
编辑 routes/web.php
, 添加以下内容
Route::group(['prefix' => 'admin'], function () { Route::group(['middleware' => 'auth.admin'], function () { Route::get('/', 'Admin\IndexController@index'); }); Route::get('login', 'Admin\LoginController@showLoginForm')->name('admin.login'); Route::post('login', 'Admin\LoginController@login'); Route::post('logout', 'Admin\LoginController@logout'); });
后台管理认证中间件
创建后台管理认证中间件
1 php artisan make:middleware AuthAdmin
编辑 AuthAdmin
<?php namespace App\Http\Middleware; use Closure; class AuthAdmin { /** * Handle an incoming request. * * @param \Illuminate\Http\Request $request * @param \Closure $next * @return mixed */ public function handle($request, Closure $next) { if (auth()->guard('admin')->guest()) { if ($request->ajax() || $request->wantsJson()) { return response('Unauthorized.', 401); } else { return redirect()->guest('admin/login'); } } return $next($request); } }
创建后台管理登录跳转中间件,用于有些操作在登录之后的跳转
1 php artisan make:middleware GuestAdmin
编辑该中间件的 handle
方法
public function handle($request, Closure $next) { if (auth()->guard('admin')->check()) { return redirect('/admin'); } return $next($request); }
在 app/Http/Kernel.php
中注册以上中间件
1 protected $routeMiddleware = [ 2 ...... 3 'auth.admin' => \App\Http\Middleware\AuthAdmin::class, 4 'guest.admin' => \App\Http\Middleware\GuestAdmin::class, 5 ];
处理注销
经过上面的步骤,已经实现了前后台分离登录,但是不管是在前台注销,还是在后台注销,都销毁了所有的 session,导致前后台注销连在一起。所以我们还要对注销的方法处理一下。
原来的 logout 方法是这样写的,在 Illuminate\Foundation\Auth\AuthenticatesUsers
里
public function logout(Request $request) { $this->guard()->logout(); $request->session()->flush(); $request->session()->regenerate(); return redirect('/'); }
注意这一句
1 $request->session()->flush();
将所有的 session 全部清除,这里不分前台、后台,所以要对这里进行改造。
因为前台、后台注销都要修改,所以我们新建一个 trait,前后台都可以使用。
新建一个文件 app/Extensions/AuthenticatesLogout.php
<?php namespace App\Extensions; use Illuminate\Http\Request; trait AuthenticatesLogout { public function logout(Request $request) { $this->guard()->logout(); $request->session()->forget($this->guard()->getName()); $request->session()->regenerate(); return redirect('/'); } }
我们将上面的那一句改成
1 $request->session()->forget($this->guard()->getName());
只是删除掉当前 guard
所创建的 session,这样就达到了分别注销的目的。
修改 Auth/LoginController.php
和 Admin/LoginController.php
,将
1 class LoginController extends Controller 2 { 3 use AuthenticatesUsers;
改掉,在文件的前面别忘了加上 use
语句
use App\Extensions\AuthenticatesLogout; ... class LoginController extends Controller { use AuthenticatesUsers, AuthenticatesLogout { AuthenticatesLogout::logout insteadof AuthenticatesUsers; } ...
到这里,就完成了整个不同用户表登录认证的过程。
