Question

有一个小型代理服务器可以中继请求-接收答案-提供浏览器。 +/-一切正常，但是有一个错误。我通过以下方式从客户端接收数据：

   void handle_handshake(const boost::system::error_code& error, int num)
    {
    if (!error)
    {

        socket_.async_read_some(boost::asio::buffer(data_, 1024),
            boost::bind(&Session::handle_read, this,
                boost::asio::placeholders::error,
                boost::asio::placeholders::bytes_transferred, num));
    }
    else
    {
        delete this;
    }
}

void handle_read(const boost::system::error_code& error,
    size_t bytes_transferred, int num)
{
    if (!error)
    {

std::cout << "data_: " << data_ << std::endl;

}

}

在data_（char data_ [1024]）中写入数据，有时它从旧请求中获取数据，例如：

{"code":"-1","msg":"","result":"err"}

相应地，该软件包应以{“ code”：“-1”，“ msg”：“”，“ result”：“ err”}结尾...

请帮忙。读取后如何清除缓冲区或如何组织从套接字读取数据？预先谢谢你！

C ++ Boost async_read_some +缓冲区中的旧数据
