  前言

  本文主要介绍了关于Laravel 5.5基于内置的Auth模块实现前后台登陆的相关内容,更多关于Auth模块的内容大家可以参考这篇文章://

  下面话不多说了,来一起看看详细的介绍吧。

  方法如下:

  步骤1:生成Auth

  在项目建立完成后,生成内置Auth组件:

   php artisan make:auth

  步骤2:添加guard

  打开config\auth.php,为方便前后台用户切换,项目共用Users表

   guards => [ //... admin => [ driver => session, provider => users, ], //... ],

  步骤3:实现基类

   class AdminController extends BaseController { use AuthorizesRequests, DispatchesJobs, ValidatesRequests; public function __construct() { $this->middleware(auth:admin); } }

  步骤4:实现后台登陆控制器

  新建appcontrollersAdminLoginController.php

   <?php namespace App\Http\Controllers\Admin; use App\Http\Controllers\Controller; use Illuminate\Support\Facades\Auth; use Illuminate\Foundation\Auth\AuthenticatesUsers; use Illuminate\Http\Request; 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. * * @var string */ protected $redirectTo = /admin; /** * Create a new controller instance. * * @return void */ public function __construct() { $this->middleware(guest:admin)->except(logout); } /** * 重写登陆页面 * @return \Illuminate\Contracts\View\Factory\Illuminate\View\View */ public function showLoginForm() { return view(backend.login); } /** * 重写退出方法 * @param Request $request * @return \Illuminate\Http\RedirectResponse\Illuminate\Routing\Redirector */ public function logout(Request $request) { $this->guard()->logout(); $request->session()->flush(); $request->session()->regenerate(); return redirect(/admin/login); } /** * 重写guard认证 * @return mixed */ protected function guard() { return Auth::guard(admin); } }

  步骤5:实现登陆后跳转到不同路径

  app\Middleware\RedirectIfAuthenticated.php

   public function handle($request, Closure $next, $guard = null) { if (Auth::guard($guard)->check()) { $path = $guard ? /admin : /home; return redirect($path); } return $next($request); }

  步骤6:实现未通过认证跳转不同登陆页

  app\Exceptions\Handler.php

   /** * 重写实现未认证用户跳转至相应登陆页 * @param \Illuminate\Http\Request $request * @param AuthenticationException $exception * @return \Illuminate\Http\JsonResponse\Illuminate\Http\RedirectResponse */ protected function unauthenticated($request, AuthenticationException $exception) { if($request->expectsJson()){ return response()->json([message => $exception->getMessage()], 401); }else{ return in_array(admin, $exception->guards()) ? return redirect()->guest(/admin/login) : redirect()->guest(login); } }

  完成

  总结
