我试图通过使用Boost:asio库进行一些网络编程来感受我的方式.我一直在使用异步处理程序从给定的地址传输数据,当我利用asio作为函数时,它工作正常:

boost::asio::io_service io_service;
boost::asio::ip::tcp::resolver resolver( io_service);
boost::asio::ip::tcp::socket sock( io_service);
boost::array < char, 4096 > buffer;

void read_handler( const boost:: system:: error_code &ec,
        std:: size_t bytes_transferred)
{
    if (! ec)
        {
            if (std::string(buffer.data(), bytes_transferred) == "$")
            {
                    myss.str(std::string());
            }
            myss << std::string(buffer.data(), bytes_transferred);
            if (int(buffer.data()[0]) == 10)
                {
                    ....

                }
            std::cout << std::string(buffer.data(), bytes_transferred) ;//<< std::endl;
            sock.async_read_some( boost::asio::buffer( buffer), read_handler);
        }
}

void connect_handler( const boost::system::error_code &ec)
{
    if (! ec)
        {
            boost::asio::write( sock, boost::asio::buffer(
                    "GET / HTTP 1.1\r\nHost: www.google.com\r\n\r\n"));
            sock.async_read_some( …
