1、添加guard 认证驱动

'guards' => ['web' => ['driver' => 'session','provider' => 'users',],'admin' => ['driver' => 'session','provider' => 'admins',],'api' => ['driver' => 'token','provider' => 'users',],'providers' => ['users' => ['driver' => 'eloquent','model' => App\User::class,],'admins' => ['driver' => 'eloquent','model' => App\Models\Admin::class,],],复制代码

2、创建后台用户表和model

php artisan make:model Models/Admin -m复制代码

3、修改Admin模型类如下

<?phpnamespace App\Models;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',];
}复制代码

4、在数据库迁移文件 _create_admins_table ,复制 users 迁移文件里的字段

public function up()
{Schema::create('admins', function (Blueprint $table) {$table->increments('id');$table->string('name');$table->string('email');$table->string('password');$table->rememberToken();$table->timestamps();});
}执行php artisan migrate在 database/factories/ModelFactory.php, 添加如下数据：$factory->define(App\Models\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：
php artisan tinker
use App
factory(App\Models\Admin::class,5)->create() //生成5条测试数据，你要几条就输入多少(Class,num) 复制代码

5、创建控制器

php artisan make:controller Admin/LoginController
php artisan make:controller Admin/AdminController 复制代码

6、编辑 Admin/LoginController.php ,代码如下：

<?phpnamespace App\Http\Controllers\Admin;use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
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';protected $username;/*** 用户名登陆*/public function username(){return 'name';}/*** 多字段登录并判断状态*/public function attemptLogin(Request $request){$username = $request->input('name');$password = $request->input('password');// 验证用户名登录方式$usernameLogin = $this->guard()->attempt(['name' => $username, 'password' => $password,'status'=>1], $request->has('remember'));if ($usernameLogin) {return true;}// 验证手机号登录方式$mobileLogin = $this->guard()->attempt(['mobile' => $username, 'password' => $password,'status'=>1], $request->has('remember'));if ($mobileLogin) {return true;}// 验证邮箱登录方式$emailLogin = $this->guard()->attempt(['email' => $username, 'password' => $password,'status'=>1], $request->has('remember'));if ($emailLogin) {return true;}return false;}/*** 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 showLoginForm(){return view('admin.login');}/*** 退出到登录页面*/public function logout(Request $request){$this->guard()->logout();$request->session()->invalidate();return redirect('/admin/login');}/*** 验证登录*/protected function validateLogin(Request $request){$this->validate($request, [$this->username() => 'required|string','password' => 'required|string','captcha' => 'required|captcha',]);}/*** 自定义认证驱动*/protected function guard(){return auth()->guard('admin');}
}复制代码

7、在 LoginController 中我们在构造函数中修改了 guest 中间件

• app\Http\Middleware\RedirectIfAuthenticated.php

<?phpnamespace App\Http\Middleware;use Closure;
use Illuminate\Support\Facades\Auth;class RedirectIfAuthenticated
{/*** 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)->check()) {// 根据不同 guard 跳转到不同的页面$url = $guard ? '/admin':'/';return redirect($url);}return $next($request);}
}复制代码

8、编辑 Admin/AdminController.php ,代码如下

<?phpnamespace App\Http\Controllers\Admin;use Illuminate\Http\Request;use App\Http\Requests;
use App\Http\Controllers\Controller;class AdminController extends Controller
{/*** Create a new controller instance.** @return void*/public function __construct(){$this->middleware('auth.admin:admin');}/*** Show the application dashboard.** @return \Illuminate\Http\Response*/public function index(){dd('后台首页，当前用户名：'.auth('admin')->user()->name);}
}复制代码

9、在 AdminController 构造函数中我们添加了一个 auth.admin Middlewar

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

10、在 app\Http\Kernel.php 中注册：

protected $routeMiddleware = [......'auth.admin' => \App\Http\Middleware\AdminAuth::class,......
];复制代码

11、在 routes/web.php 中添加如下路由：

Route::group(['prefix'=>'admin','namespace'=>'Admin'],function (){//后台登陆退出Route::get('login', 'LoginController@showLoginForm')->name('admin.login');Route::post('login', 'LoginController@login');Route::post('logout', 'LoginController@logout')->name('admin.logout');//后台首页Route::get('/', 'AdminController@index')->name('admin.index');});复制代码

最后把提交地址的路由改成 {{ route('admin.login') }}
