首先,感谢您提供讨论问题的平台。
我发现qpid cpp客户端程序有问题。
try{
cout << "Trying to open a connection" << endl;
connection.open("1.1.1.8", 10002);
session = connection.newSession();
SubscriptionManager subscriptions(session);
Listener listener(subscriptions);
subscriptions.subscribe(listener, receiver_queue);
// subscriptions.run();
subscriptions.start();
sleep(10);
}
catch(const std::exception& error) {
DEBUG(DBG_ERR, (char *)"AMQP-[%s]: Connection Error [%s].", __func__,error.what());
connection.close();
return RESULT_FAILURE;
}
subscriptions.start之后,如果我向客户端程序发送任何消息,则可以看到已收到消息,但失败,但以下异常。
terminate called after throwing an instance of 'qpid::Exception'
what(): Invalid argument (../include/qpid/sys/posix/Mutex.h:116)
Aborted
堆栈说..

我在这里想念什么吗?
请帮我。
最佳答案
不要使用SubscriptionManager :: start()-因为不允许处理异常,它已损坏-请改用SubscriptionManager :: run(),并在需要时产生一个新线程。
我也强烈建议您使用qpid :: messaging API,而不要使用旧的qpid :: client API。前者更简单,将允许更轻松地过渡到AMQP 1.0,这就是所有新开发都将发生的地方。
