Laravel5.5里面有4个默认的路由文件，其中web.php是默认路由文件，如果需要添加其他路由文件，按照以下步骤进行。
此处以添加网站home前端路由举例，我已经先在/app/Http/Controller/文件夹下创建了一个Home文件夹，这个文件夹下主要放网站前端控制器，其他步骤如下：
在项目routes目录下添加路由文件home.php；
修改/app/providers/RouteServiceProvider.php
（1）添加路由方法
protected function mapHomeRoutes() { Route::prefix(‘home’) ->middleware(‘home’) ->namespace($this->namespace.’\Home’) ->group(base_path(‘routes/home.php’)); } （2）将添加的路由方法加入map方法中执行
public function map() { $this->mapApiRoutes(); $this->mapWebRoutes(); $this->mapHomeRoutes(); // 添加执行的路由方法 } 附完整的RouteServiceProvider.php代码：
<?php namespace App\Providers; use Illuminate\Support\Facades\Route; use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider; class RouteServiceProvider extends ServiceProvider { /** * This namespace is applied to your controller routes. * * In addition, it is set as the URL generator's root namespace. * * @var string */ protected $namespace = 'App\Http\Controllers'; /** * Define your route model bindings, pattern filters, etc. * * @return void */ public function boot() { // parent::boot(); } /** * Define the routes for the application. * * @return void */ public function map() { $this->mapApiRoutes(); $this->mapWebRoutes(); $this->mapHomeRoutes(); } /** * Define the "web" routes for the application. * * These routes all receive session state, CSRF protection, etc. * * @return void */ protected function mapWebRoutes() { Route::middleware('web') ->namespace($this->namespace) ->group(base_path('routes/web.php')); } /** * Define the "api" routes for the application. * * These routes are typically stateless. * * @return void */ protected function mapApiRoutes() { Route::prefix('api') ->middleware('api') ->namespace($this->namespace) ->group(base_path('routes/api.php')); } protected function mapHomeRoutes() { Route::prefix('home') ->middleware('home') ->namespace($this->namespace.'\Home') ->group(base_path('routes/home.php')); } } 3. 在/app/Http/Kernel.php中添加home类名及其路径 protected $routeMiddleware = [ 'auth' => \Illuminate\Auth\Middleware\Authenticate::class, 'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class, 'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class, 'can' => \Illuminate\Auth\Middleware\Authorize::class, 'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class, 'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class, // 根据之前设置的路由规则名（home）对应添加home类名，并指向路由验证路径 'home' => \App\Http\Middleware\VerifyHome::class, ]; 4. 在/app/Http/Middleware/文件夹下创建VerifyHome.php，并写入验证代码 代码如下： <?php namespace App\Http\Middleware; use Closure; class VerifyHome { public function handle($request, Closure $next) { // if ("判断条件") { return $next($request); // } // 返回跳转到网站首页 // return redirect('/'); } } 上面没有执行对home路由请求的验证，如果有需要自己加上。 5. 测试举例 （1）在home.php路由里添加两条路由规则，代码如下： <?php Route::get('aaa', 'IndexController@index'); Route::get('sss', 'IndexController@home'); （2）在/app/Http/Controller/Home/文件夹下创建IndexController.php，创建方式可以直接在文件夹下创建文件，也可以使用工具匠( php artisan make:controller Home\UserController )，控制器代码如下： <?php namespace App\Http\Controllers\Home; use App\Http\Controllers\Controller; use App\User; use Illuminate\Http\Request; class IndexController extends Controller { public function index() { echo "111222"; } public function home() { echo "333"; } } （3）访问测试： a. 访问 laravel.com/home/aaa b. 访问 laravel.com/home/bbb 注意：访问默认路由web.php下的规则不用加web，访问其他路由文件需要加上在RouteServiceProvider.php中定义的路由名。
