请问用boost如何写个与flash进行socket通行的服务器 - Chinaunix

#include <ctime>
#include <iostream>
#include <string>
#include <boost/asio.hpp>

using boost::asio::ip::tcp;

std::string make_daytime_string()
{
  using namespace std; // For time_t, time and ctime;
  time_t now = time(0);
  return ctime(&now);
}

int main()
{
  try
  {
boost::asio::io_service io_service;

tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), 3099));
std::string flash_str = "<cross-domain-policy><allow-access-from domain=\"*\" to-ports=\"1025-29999\"/></cross-domain-policy>\0";
//boost::asio::mutable_buffers_1 flash_response(&flash_str, flash_str.length());
//boost::array<char, 128> flash_response = {'<','c','r','o','s','s','-','d','o','m','a','i','n','-','p','o','l','i','c','y','>','<','a','l','l','o','w','-','a','c','c','e','s','s','-','f','r','o','m',' ','d','o','m','a','i','n','=','"','*','"',' ','t','o','-','p','o','r','t','s','=','"','1','0','2','5','-','2','9','9','9','9','"','/','>','<','/','c','r','o','s','s','-','d','o','m','a','i','n','-','p','o','l','i','c','y','>'};
