URI enconding hell using Dahua HTTP API

[rmundel]

Hey guys, maybe someone can shed some light for me.

I'm trying to use Saloon to build a SDK for Dahua IPC HTTP APIs and almost lost my mind trying to change Guzzle default enconding behaviour.

Digging old issues and the docs, I had successfully changed the parameters enconding:

public function handlePsrRequest(RequestInterface $request, PendingRequest $pendingRequest): RequestInterface
    {
        // DAHUA params encoding
        return $request->withUri(
            $request->getUri()->withQuery(
                preg_replace(
                    '/%5B%5D/',
                    '[]',
                    rawurldecode($request->getUri()->getQuery())
                )
            )
        );
    }

But this hellish endpoint requires me to change de URI enconding:

It is expecing raw square brackets and doesn't know to interpret %5B for [ or %5D for ].

I tried using Guzzle directly without any success either.

The only way that I've found to make it work is to use the curl client directly (curl_init();).

Any toughts on how to make it work or use curl inside of some Saloon class?

Thanks!
