Consumer receive message only once

[lqj19...@gmail.com]

The consumer receive message only once. The code is as follows:

Channel::ptr_t channel = Channel::Create();
 string QUEUE_NAME = "hello";

 cout << " [*] Waiting for messages. To exit press CTRL+C" << endl;
 string consumer = channel->BasicConsume(QUEUE_NAME, "", true, false);
 while (1){
  BasicMessage::ptr_t msg_out = channel->BasicConsumeMessage(consumer)->Message();
  cout << "Message text: " << msg_out->Body() << endl;
 }

I 'm sure the publisher is fine. Because when I use consumer written by python, it can receive every message send by the publisher. But when I use consumer in C++, it does not work. The consumer just receive the first messages. Why it happens? Can anyone help me? Thank you very much!

You need to explicitly ack the received message using Channel::BasicAck or set no_ack when declaring the consumer (e.g., no_ack = true when calling Channel::BasicConsume.
