Slim 3 get current route in middleware

Question

I want to get the name of the current I route in a middleware class. Previously (in Slim 2.*) you could fetch the current route like so:

$route = $this->ap

Answer 1

$request->getUri()->getPath()

Get current Route, even in middleware.

Answer 2

For Slim3, here is an example showing you how to get routing information from within middleware, which is actually a combination of previous answers put together.

<?php

$slimSettings = array('determineRouteBeforeAppMiddleware' => true);

// This is not necessary for this answer, but very useful
if (ENVIRONMENT == "dev")
{
    $slimSettings['displayErrorDetails'] = true;
}

$slimConfig = array('settings' => $slimSettings);
$app = new \Slim\App($slimConfig);


$myMiddleware = function ($request, $response, $next) {

    $route = $request->getAttribute('route');
    $routeName = $route->getName();
    $groups = $route->getGroups();
    $methods = $route->getMethods();
    $arguments = $route->getArguments();

    print "Route Info: " . print_r($route, true);
    print "Route Name: " . print_r($routeName, true);
    print "Route Groups: " . print_r($groups, true);
    print "Route Methods: " . print_r($methods, true);
    print "Route Arguments: " . print_r($arguments, true);
};

// Define app routes
$app->add($myMiddleware);


$app->get('/', function (\Slim\Http\Request $request, Slim\Http\Response $response, $args) {
    # put some code here....
})

In my case, I wanted to add middleware that would ensure the user was logged in on certain routes, and redirect them to the login page if they weren't. I found the easiest way to do this was to use ->setName() on the routes like so:

$app->get('/', function (\Slim\Http\Request $request, Slim\Http\Response $response, $args) {
    return $response->withRedirect('/home');
})->setName('index');

Then if this route was matched, the $routeName in the middleware example will be "index". I then defined my array list of routes that didn't require authentication and checked if the current route was in that list. E.g.

if (!in_array($routeName, $publicRoutesArray))
{
    # @TODO - check user logged in and redirect if not.
}

Answer 3

Does the following provide you with sufficient information you require or do you also need the 'request' bit in routeInfo?

$app->getContainer()->get('router')->dispatch($req);

If you also require the 'request' bit then you will need to manually do the same thing dispatchRouterAndPrepareRoute does.

if ($routeInfo[0] === Dispatcher::FOUND) {
            $routeArguments = [];
            foreach ($routeInfo[2] as $k => $v) {
                $routeArguments[$k] = urldecode($v);
            }

            $route = $router->lookupRoute($routeInfo[1]);
            $route->prepare($request, $routeArguments);

            // add route to the request's attributes in case a middleware or handler needs access to the route
            $request = $request->withAttribute('route', $route);
        }

        $routeInfo['request'] = [$request->getMethod(), (string) $request->getUri()];

Hope this helps.

Here's how you get current route in your middleware in Slim framework 3:

$routeInfo = $request->getAttribute('routeInfo');

Note that you should use this inside __invoke() function in your middleware. Here's the sample usage:

public function __invoke($request, $response, $next)
    {
        ....
        $routeInfo = $request->getAttribute('routeInfo');
        ....
    }

$routeInfo shall then contain an object like:

{
    "0": 1,
    "1": "route6",
    "2": {
      "name": "loremipsum"
    },
    "request": [
      "POST",
      "http://example.org/loremipsum"
    ]
  }

Answer 5

Apparently you can configure Slim to determine the route before going into the middleware with this setting:

$app = new Slim\App([
    'settings'  => [
        'determineRouteBeforeAppMiddleware' => true,
    ]
]);

I'm not sure what kind of impact this has, but it works for me :)
