About Boost.Format
The format library provides a class for formatting arguments according to a format-string, as does printf, but with two major differences: format sends the arguments to an internal stream, and so is entirely type-safe and naturally supports all user-defined types; the ellipsis (...) can not be used correctly in the strongly typed context of format, and thus the function call with arbitrary arguments is replaced by successive calls to an argument feeding operator%.
int main()
{
net::io_context ioc;
tcp::resolver resolver(ioc);
beast::tcp_stream stream(ioc);
stream.connect(resolver.resolve("example.com", "80"));
http::request<http::empty_body> req{http::verb::get, "/", 11};
req.set(http::field::host, "example.com");
http::write(stream, req);
beast::flat_buffer buffer;
http::response<http::string_body> res;
http::read(stream, buffer, res);
std::cout << res << std::endl;
