php – 无法读取RabbitMQ的所有消息

$connection = new AMQPConnection(
    $AMQP_config['server'],$AMQP_config['port'],$AMQP_config['user'],$AMQP_config['password'],$AMQP_config['virtual_host']
);

$channel = $connection->channel();

$channel->basic_qos(
    null,1,null
);

$channel->basic_consume(
    $AMQP_config['queue'],'',false,array($this,'CallbackResponse')
);

while(count($channel->callbacks)) {
    $channel->wait();
}

$channel->close();
$connection->close();

public function CallbackResponse(AMQPMessage $msg)
{
    $response = json_decode($msg->body)->acopMessage;
    if ($response->reqMRef == $this->_request_reference) {
        $msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
    }
}

我的RabbitMQ服务器上有5条消息.但我只收到一个回调,只有一个进入CallbackResponse().

我想检查队列中的所有消息,找到我发送的消息,阅读它,这样就会留下4条消息.

我做错了什么,为什么我只收到第一条消息？
