我可以将 rabbit mq exchange 与我的node.js server. 但是，如果我从 Rabbit MQ UI 手动删除交换，那么有什么方法可以检查node.js交换是否被删除或connection关闭。
因为在同一交易所发布消息时，node.js崩溃并且我无法exception使用try catch. 我想node.js在处理后重新创建交换exception。
exchange.publish(ROUTING_KEY, msg); //here exchange is already deleted so throwing below error

有没有办法抓住这个exception？
