Some resemblance of a REST API

[hjri]

Here you go, some resemblance of a proper REST API:

• Everything is in /api/v1
• Reports 200 OK with relevant data on requests (errors etc handled by libhttp mostly it seems)
• relevant GET/POST/DELETE methods used for controlling internals of the emulator:
  • GET = report status
  • POST = set value/turn on
  • DELETE = unset value/turn off

Endpoints:

• /dispenser - POST sets it to full, DELETE to empty, responds with plaintext "empty" or "full", GET yields current status
• /insertedCard - POST sets it to card present, optionally ?cardname=... argument to set loaded card, DELETE sets it to card empty (doesn't update card name), GET yields current status (both cardname and inserted status)
• /cards - same as old /actions?list

Future thoughts:

• Add endpoints for fetching raw card data?
• Add endpoint that fetches general status of emulator that has all the stuff in one place?

P.S. I'm a complete noob in C(++), excuse the bad code/copypaste. P.P.S. DB9 breakout adapters finally arrived, will be testing emulator this weekend hopefully.

I'm not entirely sold on having them separated (for example multiple get commands should be handled by the same lambda), but I don't think it's worth bike shedding over.

Something like this.

svr.Post(R"(/methods/(\w+))", [&](const httplib::Request &req, httplib::Response &res) {
        auto match = req.matches[1];
        std::string str(match);
        spdlog::info("Method: {}", str);
}

I'll make the assumption that it works and merge.

RE: Hardware tests, be sure to read the "new" readme, I've added baud speed support and parity to the config as well.

Thanks!
