Use laravel5.5 to implement a function. This article mainly introduces to you the relevant information on how Laravel 5.5 implements front-end and back-end login based on the built-in Auth module. The article introduces it in detail through sample code. I hope it can help you.
The method is as follows:
Step 1: Generate Auth
After the project is established, generate the built-in Auth component:
php artisan make:auth
Step 2: Add guard
Open config\auth.php. In order to facilitate front-end and back-end user switching, the projects share the Users table
'guards' => [ //... 'admin' => [ 'driver' => 'session', 'provider' => 'users', ], //... ],
Step 3: Implement the base class
class AdminController extends BaseController { use AuthorizesRequests, DispatchesJobs, ValidatesRequests; public function __construct() { $this->middleware('auth:admin'); } }
Step 4: Implement background login control Device
New 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(); $request->session()->regenerate(); return redirect('/admin/login'); } /** * 重写guard认证 * @return mixed */ protected function guard() { return Auth::guard('admin'); } }
Step 5: Jump to different paths after login
app\Middleware\RedirectIfAuthenticated.php
public function handle($request, Closure $next, $guard = null) { if (Auth::guard($guard)->check()) { $path = $guard ? '/admin' : '/home'; return redirect($path); } return $next($request); }
Steps 6: Implementation of jumping to different login pages if authentication fails
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'); } }
