fastRoute如何使用？

[legendyang1]

我想自己结合composer写个自己的简单的框架。在git上搜索这个fastRoute是排名第一的路由三方库。

require __DIR__ . '/../config/base.php';
// Autoload 自动载入
require  VENDOR_PATH.'autoload.php';
// 路由配置
require CONFIG_PATH.'routes.php';

这是我的入口文件。

//fastroute路由
$dispatcher = \FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {
    $r->addRoute('GET', '/', 'get_all_users_handler');
    // {id} must be a number (\d+)
    $r->addRoute('GET', '/user/{id:\d+}', 'get_user_handler');
    // The /{title} suffix is optional
    $r->addRoute('GET', '/articles/{id:\d+}[/{title}]', 'get_article_handler');
});

// Fetch method and URI from somewhere
$httpMethod = $_SERVER['REQUEST_METHOD'];
$uri = $_SERVER['REQUEST_URI'];

// Strip query string (?foo=bar) and decode URI
if (false !== $pos = strpos($uri, '?')) {
    $uri = substr($uri, 0, $pos);
}
$uri = rawurldecode($uri);

$routeInfo = $dispatcher->dispatch($httpMethod, $uri);

switch ($routeInfo[0]) {
    case FastRoute\Dispatcher::NOT_FOUND:
        // ... 404 Not Found
        echo '404 Not Found';
        break;
    case FastRoute\Dispatcher::METHOD_NOT_ALLOWED:
        $allowedMethods = $routeInfo[1];
        // ... 405 Method Not Allowed
        echo '405 Method Not Allowed';
        break;
    case FastRoute\Dispatcher::FOUND:
        $handler = $routeInfo[1];
        $vars = $routeInfo[2];
        // ... call $handler with $vars
        doAction($handler,$vars);
        break;

手册上是这么写的，怎么给他跟tp那样似的指向到目录下某个文件中的某个方法啊？我基础差不懂，求大神知道下，我这个框架该怎么实现呢？
