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：http://www.zzvips.com/article/171443.html
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：
|
1
|
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

<?phpnamespace 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
