如何在Boost中从http::response读取报头

#include <boost/asio.hpp>
#include <boost/beast.hpp>

boost::beast::http::response<boost::beast::http::dynamic_body> response;
boost::beast::http::read_header(stream, buffer, response);

#include <iostream>
#include <boost/asio.hpp>
#include <boost/beast.hpp>

int main()
{
    boost::asio::io_context io_context;
    boost::asio::ip::tcp::socket socket(io_context);
    boost::asio::ip::tcp::resolver resolver(io_context);
    boost::asio::connect(socket, resolver.resolve("www.example.com", "http"));

    boost::beast::flat_buffer buffer;
    boost::beast::http::response<boost::beast::http::dynamic_body> response;
    boost::beast::http::read_header(socket, buffer, response);

    std::cout << "Status code: " << response.result_int() << std::endl;
    std::cout << "Content-Type: " << response.at("Content-Type").to_string() << std::endl;

    return 0;
}
