A simple http server library written in C++20.

Usage

Build the library

Requires GCC 12 or higher.

make lib -j

The library will be built in the ./build/lib directory.

Build the example

gcc -std=c++20 -lsimple_http -lpthread -o http_server http_server.cpp

Example

All examples are in the examples directory.

HTTP Server

For http server, the wwwroot directory is the root directory of the server to serve static files. The default port is 80.

#include <net/http/http_server.hpp>

using namespace std;
using namespace simple_http::net;
using namespace simple_http::net::http;

int main(int argc, char* argv[]) {
  EventLoopThread thread;
  thread.Run();

  http::HttpServer server{thread.GetLoop()};

  server.Start();

  thread.Wait();
  return 0;
}

Web API

For web api, it won't serve static files. The default port is 80.

#include <net/http/http_server.hpp>

using namespace std;
using namespace simple_http::net;
using namespace simple_http::net::http;

int main(int argc, char* argv[]) {
  EventLoopThread thread;
  thread.Run();

  http::HttpServer server{thread.GetLoop()};

  server.Get("hello", [](HttpRequest const& req, HttpResponse& resp) {
    resp.SetStatusCode(200);
    resp.SetStatusMessage("OK");
    resp.SetBody("Hello World!\n");
  });

  server.Start();

  thread.Wait();
  return 0;
}

TCP Server

#include <net/event_loop_thread.hpp>
#include <net/inet_addr.hpp>
#include <net/tcp_server.hpp>

using namespace std;
using namespace simple_http::net;

int main(int argc, char *argv[]) {
  EventLoopThread thread;
  thread.Run();

  InetAddr addr{1234};

  TcpServer server{thread.GetLoop(), addr};
  server.SetEventLoopGroupNum(2);
  server.Start();
  thread.Wait();
  return 0;
}
