boost::asio UDP how to receive messages on Windows?
I have two clas开发者_如何学Cses UDPSender and UDPReceiver.
Senarios: (1)It works when I run UDPSender in QNX and UDPReceiver in Linux. (2)It doesn't work when I run UDPSender in QNX and UDPReceiver in WindowsXP.(But I see UDP datagrams using Wireshark, meaning Sender is working as in Senario(1)) (3)It partially works in Windows. i) if I use Sender sending UDP messages to 127.0.0.1, Receiver can get messages ii) if I use Sender sending UDP messages to 192.168.1.137(local address in the network), Receiver can NOT receive.My question is:
How can I get Receiver working on Windows?
some code:
UDPReceiver::UDPReceiver( boost::asio::io_service& service, unsigned short port )
: m_service( service ),
m_socket( service, udp::endpoint(udp::v4(), port)),
m_peerEndpoint(),
m_buffer(),
m_messageReceipient()
{
}
void UDPReceiver::SetMessageReceipient( const boost::function<void(const char*, unsigned int)>& r )
{
m_messageReceipient = r;
}
void UDPReceiver::Start()
{
m_socket.async_receive_from(
boost::asio::buffer(m_buffer, m_buffer.size()), m_peerEndpoint,
boost::bind( &UDPReceiver::HandleReceived, shared_from_this(),
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
}
void UDPReceiver::Stop()
{
m_socket.close();
}
void UDPReceiver::HandleReceived( const boost::system::error_code& error, size_t bytesReceived )
{
assert( !m_messageReceipient.empty() );
if( error ) {
LOG( Comms, Error, "UDPReceiver:" << error.message() );
}
else {
m_messageReceipient( &m_buffer.front(), bytesReceived );
m_socket.async_receive_from(
boost::asio::buffer(m_buffer, m_buffer.size()), m_peerEndpoint,
boost::bind( &UDPReceiver::HandleReceived, shared_from_this(),
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
}
}
It's probably being blocked by the Windows Firewall.
