路由服务提供者

Testing Is Documentation

tests/Router/RouterProviderTest.php

路由主要由路由服务来接入框架，可以做一些设置。

namespace App\Infra\Provider;

use App\Middleware\Auth;
use Leevel\Router\RouterProvider;
use Leevel\Session\Middleware\Session;
use Leevel\Throttler\Middleware\Throttler;

class Router extends RouterProvider
{
    /**
     * 控制器相对目录.
     */
    protected ?string $controllerDir = 'Controller';

    /**
     * 中间件分组.
     *
     * - 分组可以很方便地批量调用组件.
     */
    protected array $middlewareGroups = [
        // web 请求中间件
        'web' => [
            'session',
        ],

        // api 请求中间件
        'api' => [],
    ];

    /**
     * 中间件别名.
     *
     * - HTTP 中间件提供一个方便的机制来过滤进入应用程序的 HTTP 请求.
     * - 例外在应用执行结束后响应环节也会调用 HTTP 中间件.
     */
    protected array $middlewareAlias = [
        'auth'       => Auth::class,
        'session'    => Session::class,
    ];

    /**
     * 基础路径.
     */
    protected array $basePaths = [
        'api/test' => [
            'middlewares' => 'api',
        ],
        'api/v*' => [

        ],
    ];

    /**

     */
    protected array $groups = [

        '/api/v1' => [

        ],
        'web/v2' => [
            'middlewares' => 'web',
        ],
    ];

    /**
     * {@inheritDoc}
     */
    public function bootstrap(): void
    {
        parent::bootstrap();
    }

    /**
     * {@inheritDoc}
     */
    public function getRouters(): array
    {
        return parent::getRouters();
    }
}

Uses

<?php

use Leevel\Di\Container;
use Leevel\Kernel\App;
use Leevel\Router\Router;
use Leevel\Router\RouterProvider;
use Leevel\Router\ScanRouter;
use Leevel\Router\Url;
use Tests\Router\Middlewares\Demo1;
use Tests\Router\Middlewares\Demo2;
use Tests\Router\Middlewares\Demo3;

基本使用

QueryPHP 路由最终结果主要由 base_paths、groups 和 routers 构成。

fixture 定义

路由服务提供者 Tests\Router\RouterProvider1

namespace Tests\Router;

class RouterProvider1 extends RouterProvider
{
    protected ?string $controllerDir = 'Tests\\Router\\Apps';

        ],
        'group2' => [
            'demo1',
            'demo3:10,world',
        ],
        'group3' => [

            'demo2',
            'demo3:10,world',
        ],
    ];

    protected array $middlewareAlias = [
        'demo1' => Demo1::class,
        'demo2' => Demo2::class,

    ];

    protected array $basePaths = [];

    public function bootstrap(): void

    }

    public function getRouters(): array

    protected function makeScanRouter(): ScanRouter
    {
        $scanRouter = parent::makeScanRouter();
        $scanRouter->setControllerDir('');

        return $scanRouter;
    }
