Python [Errno 98] 地址已被使用 [英] Python [Errno 98] Address already in use

问题描述

在我的 Python 套接字程序中，我有时需要用 Ctrl-C 中断它.当我这样做时，它会使用 socket.close() 关闭连接.

In my Python socket program, I sometimes need to interrupt it with Ctrl-C. When I do this, it does close the connection using socket.close().

但是，当我尝试重新打开它时，我必须等待大约一分钟才能再次连接.如何正确关闭套接字?还是有意为之?

However, when I try to reopen it I have to wait what seems like a minute before I can connect again. How does one correctly close a socket? Or is this intended?

推荐答案

是的，它是有意的.在这里你可以阅读详细解释.可以通过在套接字上设置 SO_REUSEADDR 选项来覆盖此行为.例如:

Yes, it is intended. Here you can read detailed explanation. It is possible to override this behavior by setting SO_REUSEADDR option on a socket. For example:

sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
