Laravel 5.5基于内置的Auth模块实现前后台登陆的详解

前言

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

html' target='_blank'>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
