英文:
Why message is not deleted in queue if there is a error after receiving a message in Rabbitmq
问题
我正在处理 RabbitMQ。在这个主题上，我是个新手。我有一个成功的发送者和接收者。在这方面我没有问题，但我注意到如果代码出现错误，消息会被卡在队列里。
详细来说，当我从队列中获取消息时，这条消息应该被删除。无论是否出现错误，都不应该有影响。因为队列不能判断这条消息是否被成功处理。队列只负责投递，对吗？那么队列怎么知道程序出错并且需要保留消息呢？😀
所以我一直反复收到相同的消息。
如果你们能帮我了解 RabbitMQ 的基础知识，我将不胜感激。谢谢，祝你们所有人有美好的一天！😀
英文:
I am working on Rabbitmq. I am a newbie in this topic. I have a successful sender and receiver. I have no problem at that but I noticed that if there is a fail in code message stuck in a queue.
If I explain in detail, When I get the message from a queue, the message should be deleted. It should do not matter is there a fail or not. Because queue cant tells this message successfully processed or not. The queue just delivers right? So how the hell queue understands the program that there is a fail in code and keep the message. 
So I just receive the message again and again.
If u guys help me about the basics of Rabbitmq. I will be glad. Thx Have a good day all of u

消息会保留在队列中，直到收到确认。如果在消息收到确认之前，接收消息的连接发生故障，该消息不会被删除，而会在之后重新投递。
在您的情况下，您可能希望激活自动确认机制。
英文:
Messages stay in queues until they are acknowledged, if a connection that was sent a message fails before the message is acknowledged, the message is not deleted and it's redelivered later.
In your case you may want to activate automatic acknowledgement
