Laravel 5.3 的 Auth 认证在 5.2 的基础上又有一些改变,本文说明如何在 Laravel 5.3 下做不同用户表的登录认证。
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)。
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,
],
],
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');
}
}
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
public function run()
{
factory('App\Admin', 3)->create([
'password' => bcrypt('123456')
]);
}
在 database/seeds/DatabaseSeeder.php
的 run
方法里调用 AdminsTableSeeder
类
public function run()
{
$this->call(AdminsTableSeeder::class);
}
执行数据库迁移命令
php artisan migrate --seed
数据库里会创建 admins 表,并且生成了3条数据
id
name
password
remember_token
create_at
update_at

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');
}
}
复制 views/layouts/app.blade.php
成 views/layouts/admin.blade.php
编辑后台管理布局模板

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="col-md-6">

@endsection
复制 views/home.blade.php
成 views/admins/index.blade.php
编辑该模板
@extends('layouts.admin')
@section('content')

<div class="col-md-8 col-md-offset-2">

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');
});
创建后台管理认证中间件
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
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
protected $routeMiddleware = [
......
'auth.admin' => \App\Http\Middleware\AuthAdmin::class,
'guest.admin' => \App\Http\Middleware\GuestAdmin::class,
......
];
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
$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
$request->session()->forget($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
class LoginController extends Controller
{
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;
}
...
