vibed: How can I handle POST request? - post

Question

Could anybody help me to handle POST request, I read docs, but it's not clear to me, how to handle POST request, that I send from page, to vibed server.
I wrote next code:
import vibe.d;
import std.stdio;
void main()
{
auto router = new URLRouter;
router.any("*", &accControl);
router.any("/my", &action);
auto settings = new HTTPServerSettings;
settings.port = 8080;
settings.bindAddresses = ["::", "127.0.0.1"];
listenHTTP(settings, router);
runEventLoop();
}
void accControl(HTTPServerRequest req, HTTPServerResponse res)
{
res.headers["Access-Control-Allow-Origin"] = "*";
}
void action(HTTPServerRequest req, HTTPServerResponse res)
{
// how get string from POST request here. And how get JSON object, if server send it.
}
but what method I should use for req? As I understand expect POST body there is sending a lot of other data.
The POST request is sending with JQuery:
$.post("http://127.0.0.1:8080", "\"answers_result\":777");
So I need to get this JSON and send with vibed it's to DB. But problem that I can't understand how to handle it.

Answer 1

In main:
auto router = new URLRouter;
router.post("/url_to_match", &action);
listenHTTP(settings, router);
Action:
void action(HTTPServerRequest req, HTTPServerResponse res)
{
auto answers_result = req.json["answers_result"].to!int;
// ...
}
Or you can use registerRestInterface.

Answer 2

Here is an example code to show how to read POST params from vibe.d:
Main Function:
shared static this()
{
auto router = new URLRouter;
router.post("/url_to_match", &action);
auto settings = new HTTPServerSettings;
settings.port = 3000;
listenHTTP(settings, router);
}
Action:
void action(HTTPServerRequest req, HTTPServerResponse res)
{
// Read first POST parameter named "first_name"
auto firstName = req.form["first_name"];
// Read second POST parameter named "last_name"
auto lastName = req.form["last_name"];
// Prepare output to be sent to client.
auto name = "Hello %s, %s".format(lastName, firstName);
// Send data back to client
res.writeBody(name);
}
Build the program and run it, to try it out on your local machine you may execute the following simple curl request:
curl --data "first_name=kareem&last_name=smith" "http://localhost:3000/url_to_match"
