What could be the reason for a socket error "[Errno 9] Bad file descriptor"
提问by Alex
I have a complex python (2.7.3) script which is trying to open a socket connection via
我有一个复杂的 python (2.7.3) 脚本，它试图通过
self.socket.close()
# doing something else
self.socket.connect((host, port))
but all I get is the following socket error:
但我得到的是以下套接字错误：
error: [Errno 9] Bad file descriptor
The host:portaccepts connections as I have verified this with nc host portmanually. So what could be the possible reasons I get this error for opening a connection to the given port, which actually works?
在host:port我已经验证了这一点与接受连接nc host port手动。那么我在打开与给定端口的连接时出现此错误的可能原因是什么？
I cannot and will not post the full script as it is too complex and irrelavent for this question. I just would like to know all possible reasons for this error, and how to check them and fix them.
我不能也不会发布完整的脚本，因为它对于这个问题来说太复杂和无关紧要了。我只想知道此错误的所有可能原因，以及如何检查和修复它们。

You will need to create a new socket object. Maybe self.socket = socket.socket()after closing the previous socket and before connecting.
您将需要创建一个新的套接字对象。也许self.socket = socket.socket()在关闭前一个套接字之后和连接之前。
