擷取目前路徑

編輯此頁面

如果您需要在應用程式中存取目前的路由，您將需要使用即將到來的 ServerRequestInterface 實體化 RouteContext 物件。

在此您可以透過 $routeContext->getRoute() 取得路由，並透過 getName() 存取路由的名稱，或是透過 getMethods() 取得該路由支援的方法等。

注意：如果您需要在路由處理程式之前的中介軟體週期中存取 RouteContext 物件，您將需要在錯誤處理中介軟體之前將 RoutingMiddleware 新增為最外層中介軟體（請見下方範例）。

範例

<?php

use Slim\Exception\HttpNotFoundException;
use Slim\Factory\AppFactory;
use Slim\Routing\RouteContext;

require __DIR__ . '/../vendor/autoload.php';

$app = AppFactory::create();

// Via this middleware you could access the route and routing results from the resolved route
$app->add(function (Request $request, RequestHandler $handler) {
    $routeContext = RouteContext::fromRequest($request);
    $route = $routeContext->getRoute();

    // return NotFound for non-existent route
    if (empty($route)) {
        throw new HttpNotFoundException($request);
    }

    $name = $route->getName();
    $groups = $route->getGroups();
    $methods = $route->getMethods();
    $arguments = $route->getArguments();

    // ... do something with the data ...

    return $handler->handle($request);
});

// The RoutingMiddleware should be added after our CORS middleware so routing is performed first
$app->addRoutingMiddleware();
 
// The ErrorMiddleware should always be the outermost middleware
$app->addErrorMiddleware(true, true, true);

// ...
 
$app->run();
