尝试把web.php路由文件分成多个

1、直接在routes文件夹下创建pc.php，代码如下：

<?php

use Illuminate\Support\Facades\Route;

Route::get('test',function(){
	return 'I am pc';
});
?>

直接用网址进行访问，提示404错误，路由没有被加载，这种方法是行不通的。

2、在web.php的下边，通过

include_once('pc.php')

引入pc.php，网址访问，页面显示

I am pc

路由被正确加载，这种方法是可行的。

3、在app\Providers\RouteServiceProvider.php文件里的61行，找到laravel是如何加载web.php，进行仿写

    protected function mapWebRoutes()
    {
        Route::middleware('web')
            ->namespace($this->namespace)
            ->group(base_path('routes/web.php'));
        Route::middleware('pc')
            ->namespace($this->namespace)
            ->group(base_path('routes/pc.php'));
    }

网址访问，出现错误

Illuminate\Contracts\Container\BindingResolutionException
Target class [pc] does not exist.

原因是pc中间件未被定义，查询web的中间件的定位位置，在app\Http\Kernel.php的32行，进行仿写

        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            // \Illuminate\Session\Middleware\AuthenticateSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],
        'pc' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            // \Illuminate\Session\Middleware\AuthenticateSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

网址访问，页面显示

I am pc

路由被正确加载，这种方法是可行的。

第2和第3那种方法更好用，没有得出结论， 希望老师可以告知下！
