App\Http\Controllers\API\LegacyController::getBeatmaps PHP Method

    public function getBeatmaps()

        $set_id = Request::input('s');

        // - specify if `u` is a user_id or a username. Use `string` for usernames or `id` for user_ids. Optional, default behaviour is automatic recognition (may be problematic for usernames made up of digits only).
        $mode = get_int(Request::input('m'));

        // - the beatmap hash. It can be used, for instance, if you're trying to get what beatmap has a replay played in, as .osr replays only provide beatmap hashes (example of hash: a5b99395a42bd55bc5eb1d2411cbdf8b). Optional, by default all beatmaps are returned independently from the hash.
