最近群里很多人文档，laravel如何做会员和管理两个身份登录，今天把教程分享一下

自定义用户表登录

认证是由 guards 和 providers 两部分构成的， defaults 配置是默认选择一个 guard 认证驱动，所以我们在这两个配置项中分别添加一个 admin 和 admins 选项。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 <?php 'guards' => [ 'web' => [ 'driver' => 'session' , 'provider' => 'users' , ], 'admin' => [ 'driver' => 'session' , 'provider' => 'admins' , ], 'providers' => [ 'users' => [ 'driver' => 'eloquent' , 'model' => App\User:: class , ], 'admins' => [ 'driver' => 'eloquent' , 'model' => App\Models\Admin:: class , ], ],

标红的是我们后添加的后台管理员登录身份

创建后台用户表和model

1 2	`php artisan make:model Admin` `php artisan make:migration creaet_admins_table`

在数据库迁移文件 _create_admins_table , 我们可以复制 users 迁移文件里的字段

1 2 3 4 5 6 7 8 Schema::create( 'admins' , function (Blueprint $table ) { $table ->increments( 'id' ); $table ->string( 'name' ); $table ->string( 'email' ); $table ->string( 'password' ); $table ->rememberToken(); $table ->timestamps(); });

执行php artisan migrate

生成临时数据

在 database/factories/ModelFactory.php, 添加如下数据：

1 2 3 4 5 6 7 8 9 10 $factory ->define(App\Admin:: class , function (Faker\Generator $faker ) { static $password ; return [ 'name' => $faker ->name, 'password' => $password ?: $password = bcrypt( '123456' ), 'email' => $faker ->email, 'remember_token' => str_random(10), ]; });

打开命令行输入：

1 2 3 4 php artisan tinker use App; factory(App\Admin:: class ,5)->create() //生成5条测试数据，你要几条就输入多少(Class,num)

更改 Admin 模型类

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 <?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' , 'email' , 'password' , ]; /** * The attributes that should be hidden for arrays. * * @var array */ protected $hidden = [ 'password' , 'remember_token' , ]; }

创建控制器

1 2	`php artisan make:controller Admin/LoginController` `php artisan make:controller Admin/AdminController`

编辑 Admin/LoginController.php：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 <?php namespace App\Http\Controllers\Admin; use Illuminate\Http\Request; use App\Http\Controllers\Controller; use Illuminate\Foundation\Auth\ThrottlesLogins; use Illuminate\Foundation\Auth\AuthenticatesUsers; class LoginController extends Controller { use AuthenticatesUsers; /** * Where to redirect users after login / registration. * * @var string */ protected $redirectTo = '/admin/index' ; protected $username ; /** * Create a new controller instance. * * @return void */ public function __construct() { $this ->middleware( 'guest:admin' , [ 'except' => 'logout' ]); $this ->username = config( 'admin.global.username' ); } /** * 重写登录视图页面 */ public function showLogin() { return view( 'admin.login.index' ); } /** * 自定义认证驱动 * @return mixed */ protected function guard() { return auth()->guard( 'admin' ); } }

修改 app\Http\Middleware\RedirectIfAuthenticated.php:

1 2 3 4 5 6 7 8 9 10 public function handle( $request , Closure $next , $guard = null) { if (Auth::guard( $guard )->check()) { // 根据不同 guard 跳转到不同的页面 $url = $guard ? 'admin/dash' : '/home' ; return redirect( $url ); } return $next ( $request ); }

编辑 Admin\AdminController.php：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 <?php namespace App\Http\Controllers\Admin; use App\Http\Controllers\Controller; class AdminController extends Controller { /** * Create a new controller instance. * * @return void */ public function __construct() { $this ->middleware( 'auth.admin:admin' ); } // public function index() { dd( '用户名：' .auth( 'admin' )->user()->name); }

编辑 app\Http\Middleware\AdminAuthMiddleware.php

1 2 3 4 5 6 7 8 9 10 11 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( 'admin/login' ); } } return $next ( $request ); }

在 app\Http\Kernel.php 中注册:

1 2 3 4 protected $routeMiddleware = [ ··· ··· 'auth.admin' => \App\Http\Middleware\AdminAuthMiddleware:: class , ];

注册路由

编辑 routes/web.php ：

1 2 3 4 5 6 7 8 Route::group([ 'prefix' => 'admin' , 'namespace' => 'Admin' ], function ( $router ) { $router ->get( 'login' , 'LoginController@showLogin' )->name( 'admin.login' ); $router ->post( 'login' , 'LoginController@login' ); $router ->post( 'logout' , 'LoginController@logout' ); $router ->get( 'index' , 'AdminController@index' ); });
