WIP: http server implementation for Qt based on Ryan Dahl's http parser

QHttpServer

A Qt HTTP Server - because hard-core programmers write web-apps in C++ :)

It uses Ryan Dahl's HTTP Parser and is asynchronous and does not require any inheritance.

NOTE: QHttpServer is NOT fully HTTP compliant right now! DO NOT use it for anything complex

Installation

Requires Qt 4.

qmake && make && su -c 'make install'

To link to your projects put this in your project's qmake project file

LIBS += -lqhttpserver

By default, the installation prefix is /usr/local. To change that to /usr, for example, run:

qmake -r PREFIX=/usr

Usage

Include the headers

#include <qhttpserver.h>
#include <qhttprequest.h>
#include <qhttpresponse.h>

Create a server, and connect to the signal for new requests

QHttpServer *server = new QHttpServer;
connect(server, SIGNAL(newRequest(QHttpRequest*, QHttpResponse*)),
        handler, SLOT(handle(QHttpRequest*, QHttpResponse*)));

// let's go
server->listen(8080);

In the handler, you may dispatch on routes or do whatever other things you want. See the API documentation for what information is provided about the request via the QHttpRequest object.

To send data back to the browser and end the request:

void Handler::handle(QHttpRequest *req, QHttpResponse *resp)
{
	resp->setHeader("Content-Length", 11);
	resp->writeHead(200); // everything is OK
	resp->write("Hello World");
	resp->end();
}

The server and request/response objects emit various signals and have guarantees about memory management. See the API documentation for these.
