mq消息传送

开启消息发布确认模式

    def publish(self, message):
        """发布消息（自动重连）"""
        for i in range(3):
            try:
                message_ = json.dumps(message, ensure_ascii=False)
                self.ensure_connection()
                # 开启 confirm 模式（Publisher Confirms）
                self.channel.confirm_delivery()
                self.channel.basic_publish(
                    exchange=self.queue_exchange,
                    routing_key=self.queue_routing_key,
                    body=message_,
                    properties=pika.BasicProperties(delivery_mode=2),
                    mandatory=True
                )  # 持久化消息
                logger.info(resp_dic["infoId"] + ":" + str(message))
                # print("confirm---",str(confirm))
                return
            except Exception as e:
                logger.error(f"Publish failed: {e}. Reconnecting...{message}")
                self.is_connected = False
        else:
            logger.error("Failed to publish message after 3 attempts.")

删掉消息队列之后

1 unroutable message(s) returned. Reconnecting...
