Catch“socket.error： Connection refused”exception

我怎么能捕获socket.error: [Errno 111] Connection refusedexception？

 try: senderSocket.send("Hello") except ?????: print "catch !" 

Answer 1

通过捕获所有的 socket.errorexception，并且如果errno属性不等于111，则重新提高它。或者，更好的是使用errno.ECONNREFUSED常量：

 import errno from socket import error as socket_error try: senderSocket.send('Hello') except socket_error as serr: if serr.errno != errno.ECONNREFUSED: # Not the error we are looking for, re-raise raise serr # connection refused # handle here
