1.建中间件 php artisan make:middleware AdminMiddleware 在AdminMiddleware中添加验证代码 <?php namespace App\Http\Middleware; use Closure; use Illuminate\Support\Facades\Auth; class AdminMiddleware { /** * Handle an incoming request. * * @param \Illuminate\Http\Request $request * @param \Closure $next * @return mixed */ public function handle($request, Closure $next) { //使用中间件验证是否登陆 if(!Auth::guard('admin')->check()){ return redirect('admin/login'); } return $next($request); } } 2.挂载中间键，找到Kernel.php，在路由中间键中添加如下代码 /** * The application's route middleware. * * These middleware may be assigned to groups or used individually. * * @var array */ protected $routeMiddleware = [ 'admin.auth' => AdminMiddleware::class,//自己添加的验证代码 'auth' => \Illuminate\Auth\Middleware\Authenticate::class, 'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class, 'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class, 'can' => \Illuminate\Auth\Middleware\Authorize::class, 'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class, 'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class, ]; 3.在登陆控制器中使用中间件 //构造方法 public function __construct() { //验证，排除不使用的中间件。 $this->middleware('admin.auth')->except(['LoginForm','Login']); }
