Laravel 5.5：获取服务提供商的所有注册路线

Question

I have created a new Service provider and need to get all the registered routes in it. But Route::getRoutes()->getIterator() is returning null.

This is my full code,

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Route;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;
use Illuminate\Foundation\Application;
use Illuminate\Support\Facades\Request;

class ApiVersionServiceProvider 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';

    public function register()
    {
        if (Request::instance()->is('api/v*')) {
            $routes = [];
            foreach (Route::getRoutes()->getIterator() as $route) {
                if ((strpos($route->uri, 'api') !== FALSE) AND basename($route->uri) == basename(Request::instance()->path())) {
                    $routes[] = $route->uri;
                }
            }
            dd($routes);
        }
    }
}

Is there an alternative way to attain routes here?

According to the Documentation: https://laravel.com/docs/5.6/providers#the-boot-method

You should place your code inside of the boot() method.

This method is called after all other service providers have been registered

Currently you are trying to use Route service before it is registered itself.

So it should look like:

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Route;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;
use Illuminate\Foundation\Application;
use Illuminate\Support\Facades\Request;

class ApiVersionServiceProvider 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';

    /**
     * Using boot method to ensure it is executed when the Route service is ready to be used
     */
    public function boot()
    {
        if (Request::instance()->is('api/v*')) {
            $routes = [];
            foreach (Route::getRoutes()->getIterator() as $route) {
                if ((strpos($route->uri, 'api') !== FALSE) AND basename($route->uri) == basename(Request::instance()->path())) {
                    $routes[] = $route->uri;
                }
            }

            // Do anything you need with $routes array.
        }
    }
}
