Routing does not match (slash %2F in path parameter)

[Magnum5234]

When you have the following route:

$router->any('/something/{magic}/{foo}', function (ServerRequestInterface $request, Response $response, array $args) use ($app) {
   // do something 
});

And Call this URL:

https://some.host/something/magic/foo%2Fbar

It will not match. I tried to check what went wrong. In $_SERVER I get:

["REQUEST_URI"]=>
  string(32) "/something/magic/foo%2Fbar"

It however matches when commenting out: https://github.com/slimphp/Slim/blob/4.x/Slim/Routing/RouteResolver.php#L42

Not sure why this is there tbh? If you want the route parameter to be decoded, shouldn't this be done after routing is done?

It seems the rawurldecode($uri) was originally added to solve another issue for routes with international characters before Slim 4:

See commit 9c50cb9 in PR #2405 for issue #2399

For the specific case of %2F here that is indeed not expected if you compare with the comment $uri Should be $request->getUri()->getPath(). In fact PSR-7 gives that explicit example for getPath() when talking about percent-encoded values.

But I guess it's been around for so long now (2018) that this is a "known quirk" for Slim 4 routing? Work-around could be to double-encode %2F into %252F first...

I think is an "historical" artifact from v3 or v4, see here: #3208 (comment)

We have to do a rawurldecode() before dispatching the URI to the router otherwise it would break when encountering special chars.

We will address this in v5.
