如果你需要在应用程序中访问当前路由,你需要使用传入的 ServerRequestInterface
实例化 RouteContext
对象。
从那里你可以通过 $routeContext->getRoute()
获取路由,并通过使用 getName()
访问路由的名称,或者通过 getMethods()
获取此路由支持的方法,等等。
注意:如果你需要在到达路由处理程序之前在中间件周期中访问 RouteContext
对象,则需要将 RoutingMiddleware
添加为最外层的中间件,位于错误处理中间件之前(参见下面的示例)。
示例
<?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();
