with vibed.

I am sending POST request from AngularJS:

$.post("http://127.0.0.1:8080/my", total_result);
where total_result is JSON string: [{"QID":3,"AID":3}, 
{"SubAID":[4]}, {"MinArea":"10","MaxArea":"90"}]

Handler is look like:

void action(HTTPServerRequest req, HTTPServerResponse res)
{
    // res.statusCode = 201;
}

I know that I can set statusCode like code above, but problem 
that in Chrome console I am getting:
POST http://127.0.0.1:8080/my 404 (Not Found)
How can I pass to it (from vibed to browser) status code?

Eghm, sorry. Not req, but res, but again errr:

What difference between HTTPClientRequest and HTTPRequest ?

For example if I am getting request from web-browser what I 
should use? And why?

Here is function what have two call-backs. When it's get request 
it's work as server, when it's send response it's work like 
client or I have wrong logic?

Wrong logic. Its the server that gets the request and the server 
that send the response.

If the application (vibe.d) makes a request, it is the client. If 
the request is made to your application, it is the server.

In your case your angular app is the client, and your vibe.d app 
is the server. Therefor, HTTPServer(Request|Response).

Could you explain me about: HTTPServerRequest and HTTPRequest. I 
can't understand difference.

No idea. Probably HTTPRequest provides common functionality for 
both HTTPServerRequest and HTTPClientRequest. Just guessing.

What you want is `req.json`.

Make sure that the call from angular sets the Content-Type header 
to application/json. But I think that should happen by default.

That's because writeJsonBody's return type is void.

If you do not send any response in handler, vibe.d will try to 
match next route (if any). So you should send any response (empty 
string for example).

void action(HTTPServerRequest req, HTTPServerResponse res)
{
     res.statusCode = 201;
     res.writeBody("");
}
