creatQueue question

[ZhaoVisions]

The local server 127.0.0.1 already has a queue, but when I use creatQueue, it doesn't detect it and continues to create a new one.

Greetings, I do not know what happened before.
I use it like this:

constructor:
{ ... m_RabbitMQ.setHost(m_Host); m_RabbitMQ.setUsername(m_User); m_RabbitMQ.setPassword(m_Pass); m_RabbitMQ.setAutoReconnect(true); ... }

`
void bindToChanges(const QString &exchangeName )
{
// exchangeName == "something.state";
createExchange(exchangeName, name);
auto *queue = createQueue(l, exchangeName, name);
bindQueueToExchange(queue, exchangeName, name);
}

void createExchange(const RabbitMQContext &exchangeName, const FeatureName &name)
{
auto exc = m_RabbitMQ.createExchange(exchangeName);
connect(exc, &QAmqpExchange::declared, exc,
[exchangeName, exc, name] { qDebug() << "RabbitMQ [] Declared Exchange" << name << exchangeName << exc->isDeclared(); });
exc->declare(QAmqpExchange::FanOut, QAmqpExchange::Durable);
}

QAmqpQueue *createQueue(Bindable *l, const RabbitMQContext &exchangeName, const FeatureName &name)
{
auto queue = m_RabbitMQ.createQueue(name + m_QueueSuffix.value());
emit queueCreated(queue);
const auto rerequest = m_Feats.value(name).rabbitMqSendsSingleItemUpdates;
disconnect(queue, 0, 0, 0); // in case this is a reconnect
connect(queue, &QAmqpQueue::declared, this, [=] {
connect(queue, &QAmqpQueue::messageReceived, this, [=] {
auto data = queue->dequeue().payload();
qDebug() << "RabbitMQ update" << l->m_FeatureName << data.first(qMin(200, data.length())) << "...";
if (rerequest) {
reRequestRestValue(name);
return;
}
l->value = data;
});
queue->consume(QAmqpQueue::coNoAck);
qDebug() << "RabbitMQ [] Declared Queue" << l->m_FeatureName << queue->name();
});
queue->declare();
return queue;
}

void bindQueueToExchange(QAmqpQueue queue, const RabbitMQContext &exchangeName, const FeatureName &name)
{
connect(queue, &QAmqpQueue::bound, this, [name, exchangeName, queue] {
qDebug() << "RabbitMQ [] Bound Queue" << name << queue->name() << "to exchange " << exchangeName << " waiting for updates";
});
queue->bind(exchangeName, "");
}
