The libhttp reference manual

Introducion

libhttp is fast and simple http library to build HTTP servers with REST fashion. the purpose of the library is to provide the fastest possible access to the network, based on modern C++ approaches

Requirements

• g++ >=10.3.0
• spdlog >= 1.5.0
• fmt >=6.1.2

Building

libhttp uses standard system where the usual build process involves running

mkdir build
cd build
cmake ..
cmake --build .
make install # (optionally to install on the system)

Getting Started

The most basic example of creating a server and handling a requests for the path /hello

#include <httpserver.hpp>

using namespace libhttp;
class HelloHandler{
public:
	std::string path = "/hello";
	Response receive(const Headers& headers, const std::string& body){
		return {200, {/*No headers. default content-type: text/plain*/}, "Hello world!!"};
	}
};

int main(int argc, char** argv){
	Server<HelloHandler> server{8080};
	server.run();
	return 0;
}

To test the above example, you could run the following command from a terminal:

curl -XGET -v http://localhost:8080/hello

Create Custom header

To use your class with libhttp::Server, you need to add to the public domain:

public:
    std::string path = "<path on the server>";
    Response receive(const Headers& headers, const std::string& body);
