cann't set namesrv with hostname

[lemonzone2010]

I try to set namesrv with host name ,but it doesn’t work:

1. producer.setNamesrvAddr("name1.xxx.domain:9876;name2.xxx.domain:9876");
2. producer.setNamesrvDomain("name1.xxx.domain:9876;name2.xxx.domain:9876");

And The following error occurred:

Type: MQClientException , msg: No route info of this topic, error:-1

It's ok only when i set namesrv with ip

producer.setNamesrvAddr("192.168.0.1:9876;192.168.0.2:9876");

Maybe you can try domain name resolving before connecting.

struct sockaddr_in sin;
memset(&sin, 0, sizeof(sin));
sin.sin_family = AF_INET;
sin.sin_addr.s_addr = inet_addr(hostName.c_str());
sin.sin_port = htons(portNumber);

//////////////////////// Add these //////////////////////////
if (INADDR_NONE == sin.sin_addr.s_addr) { // Invalid ip address, maybe it's a domain name
try
{
boost::asio::io_service io_service;
boost::asio::ip::tcp::resolver resolver(io_service);
boost::asio::ip::tcp::resolver::query query(hostName, boost::lexical_cast(portNumber));

  LOG_DEBUG("dns resolving for host name: %s, service name: %s", hostName.c_str(), query.service_name().c_str());
  boost::asio::ip::tcp::resolver::iterator iter = resolver.resolve(query);

  boost::asio::ip::tcp::endpoint endpoint = iter->endpoint();
  std::string ipAddr = endpoint.address().to_string();

  LOG_DEBUG("dns resolving endpoint: %s", ipAddr.c_str());
  sin.sin_addr.s_addr = inet_addr(ipAddr.c_str());
} catch(const std::exception& e) {
  LOG_ERROR("dns resolving error: %s", e.what());
  return e_connectFail;
}

}
