#includeThis code creates an HTTP server that listens on the local address 127.0.0.1 and port 8080. When a client sends an HTTP request to the server, the server responds with a "Hello, world!" message. The package library for Cpp Network is Boost.Network, which is part of the Boost C++ Libraries collection.#include namespace http = boost::network::http; struct hello_world; typedef http::server server; struct hello_world { void operator()(const server::request& req, server::response& res) { res = server::response::stock_reply( server::response::ok, "Hello, world!"); } }; int main() { hello_world handler; server::options options(handler); options.address("127.0.0.1") .port("8080"); server serv(options); serv.run(); return 0; }
