本文是一篇关于Laravel分割路由文件(routes.php)的最佳方式教程文章,内容介绍的很详细,学习Laravel的小伙伴可以参考学习。

前言

Laravel 的路由功能很强大,默认都是定义在 routes.php 文件中,随着项目越来越大,我们需要的定义的路由越来越多,想象一下,如果几百上千个路由都定义在一个文件中,如何去维护?也许还有不同的人都在同一个文件定义路由,这就造成了冲突,因此我们需要分割 routes.php 文件。

下面介绍一种很优雅的方式。

app/Providers/RouteServiceProvider.php map 方法中可以如下定义:

public function map(Router $router)
{
  $router->group(['namespace' => $this->namespace], function ($router) {
    //require app_path('Http/routes.php');
    foreach (glob(app_path('Http//Routes') . '/*.php') as $file) {
      $this->app->make('App\\Http\\Routes\\' . basename($file, '.php'))->map($router);
    }
  });
}

文件组织结构图如下:

这样它会遍历 app/Http/Routes/ 文件夹下的文件,遍历每个文件路由类的 map 方法,每个文件的结构都类似,

举个例子:

<?php
namespace App\Http\Routes;

use Illuminate\Contracts\Routing\Registrar;

class HomeRoutes
{
  public function map(Registrar $router)
  {
    $router->group([&#39;domain&#39; => &#39;www.tanteng.me&#39;, &#39;middleware&#39; => &#39;web&#39;], function ($router) {
      $router->auth();
      $router->get(&#39;/&#39;, [&#39;as&#39; => &#39;home&#39;, &#39;uses&#39; => &#39;IndexController@index&#39;]);
      $router->get(&#39;/blog&#39;, [&#39;as&#39; => &#39;index.blog&#39;, &#39;uses&#39; => &#39;BlogController@index&#39;]);
      $router->get(&#39;/resume&#39;, [&#39;as&#39; => &#39;index.resume&#39;, &#39;uses&#39; => &#39;IndexController@resume&#39;]);
      $router->get(&#39;/post&#39;, [&#39;name&#39; => &#39;post.show&#39;, &#39;uses&#39; => &#39;ArticleController@show&#39;]);
      $router->get(&#39;/contact&#39;, [&#39;as&#39; => &#39;index.contact&#39;, &#39;uses&#39; => &#39;IndexController@contact&#39;]);
      $router->post(&#39;/contact/comment&#39;, [&#39;uses&#39; => &#39;IndexController@postComment&#39;]);
      $router->get(&#39;/travel&#39;, [&#39;as&#39; => &#39;index.travel&#39;, &#39;uses&#39; => &#39;TravelController@index&#39;]);
      $router->get(&#39;/travel/latest&#39;, [&#39;as&#39; => &#39;travel.latest&#39;, &#39;uses&#39; => &#39;TravelController@latest&#39;]);
      $router->get(&#39;/travel/{destination}/list&#39;, [&#39;as&#39; => &#39;travel.destination&#39;, &#39;uses&#39; => &#39;TravelController@travelList&#39;]);
      $router->get(&#39;/travel/{slug}&#39;, [&#39;uses&#39; => &#39;TravelController@travelDetail&#39;]);
      $router->get(&#39;/sitemap.xml&#39;, [&#39;as&#39; => &#39;index.sitemap&#39;, &#39;uses&#39; => &#39;IndexController@sitemap&#39;]);
    });
  }
}

把路由规则都写到每个文件的 map 方法中,这样一来,就实现了很好的 routes.php 文件的分开管理。此外,你也可以简单的分割,直接把 routes.php 中的定义拆散成多个文件,通过 require 的方式引入,但是哪个更好,一目了然。

那么这样路由分开多个文件后岂不是增加调用次数,会不会影响性能?答案是不必担心。通过 Laravel 的命令:

php artisan route:cache

生成路由缓存文件后,路由只会读取缓存文件的路由规则,因此不会影响性能,这样做让开发更高效和规范。
