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：//www.yinxi.net/article/121401.htm

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configauth.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 AppHttpControllersAdmin;use AppHttpControllersController;use IlluminateSupportFacadesAuth;use IlluminateFoundationAuthAuthenticatesUsers;use IlluminateHttpRequest;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 IlluminateContractsViewFactory|IlluminateViewView */ public function showLoginForm() { return view("backend.login"); } /** * 重写退出方法 * @param Request $request * @return IlluminateHttpRedirectResponse|IlluminateRoutingRedirector */ 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

appMiddlewareRedirectIfAuthenticated.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

appExceptionsHandler.php

/** * 重写实现未认证用户跳转至相应登陆页 * @param IlluminateHttpRequest $request * @param AuthenticationException $exception * @return IlluminateHttpJsonResponse|IlluminateHttpRedirectResponse */ protected function unauthenticated($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
