Question

我创建了一个新的服务提供商，需要在其中获取所有注册的路由。但是Route::getRoutes()->getIterator()返回null。

这是我的完整代码，

<?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);
        }
    }
}

在这里可以找到路线吗？

根据文档：https://laravel.com/docs/5.6/providers#the-boot-method

您应将代码放在boot()方法内。

在所有其他服务提供商都注册之后，将调用此方法

当前，您正在尝试使用路由服务进行自身注册。

因此它应该看起来像：

<?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.
        }
    }
}
