POST data in params like Flask

[Vermeille]

Hi!

I've been using Crow for a few days now, and it's missing being able to read POST data, like you get from a form.

I'm more than willing to contribute to this, but would like to discuss the best way to implement this. Should we move request.url_parans to requets.params that will contain both GET and POST params? Does that makes the server vulnerable to CSRF? Should we add request.body_params?

Thanks :)

This has been discussed, along with code examples, here: https://github.com/ipkn/crow/issues/170

In my project, I use it as in the following example:

 CROW_ROUTE(app, "/myoutputs").methods("POST"_method)
    ([&](const crow::request& req) {

        map<std::string, std::string> post_body
                = xmreg::parse_crow_post_data(req.body);

        if (post_body.count("xmr_address") == 0
            || post_body.count("viewkey") == 0
            || post_body.count("tx_hash") == 0)
        {
            return string("xmr address, viewkey or tx hash not provided");
        }

        string tx_hash     = post_body["tx_hash"];
        string xmr_address = post_body["xmr_address"];
        string viewkey     = post_body["viewkey"];

        // this will be only not empty when checking raw tx data
        // using tx pusher
        string raw_tx_data = post_body["raw_tx_data"];

        return xmrblocks.show_my_outputs(tx_hash, xmr_address,
                                         viewkey, raw_tx_data);
    });

Nice, thanks :)

Should it be contributed back in Crow, with POST data automatically parsed in the request and stored in the request object? IMHO it should, but it's up to the maintainer :)

Crow hasn't seen a single commit in about a year. It seems as it development stopped for now.
