Laravel-通过命名空间和路由实现应用模块化

laravel框架中使用命名空间和路由可以简单的实现模块化开发；

如下，添加一个后台模块Backend，使用routes_backend.php，

1、首先在路由服务中绑定对应的命名空间：

Providers\RouteServiceProvider

namespace App\Providers;
use Illuminate\Routing\Router;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;

class RouteServiceProvider extends ServiceProvider
{
    /**
     * This namespace is applied to the controller routes in your routes file.
     *
     * In addition, it is set as the URL generator's root namespace.
     *
     * @var string
     */
    protected $namespace = 'App\Http\Controllers';

    //后台命名空间定义
    protected $backendNamespace = 'App\Http\Controllers\Backend';


    /**
     * Define your route model bindings, pattern filters, etc.
     *
     * @param  \Illuminate\Routing\Router  $router
     * @return void
     */
    public function boot(Router $router)
    {
        parent::boot($router);
    }

    /**
     * Define the routes for the application.
     *
     * @param  \Illuminate\Routing\Router  $router
     * @return void
     */
    public function map(Router $router)
    {
        $router->group(['namespace' => $this->namespace], function ($router) {
            require app_path('Http/routes.php');
        });

        //后台路由绑定
        $router->group(['namespace' => $this->backendNamespace], function ($router) {
            require app_path('Http/routes_backend.php');
        });

    }
}

2、新建路由文件 routes_backend.php

<?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::get('/admin','IndexController@index')->name('admin');

3、建立 App\Http\Controllers\Backend 目录，在其中写后台的相关控制器如：

至此就可以分离访问了
