![捕获“ socket.error：[Errno 111]连接被拒绝”异常](http://www.mshxw.com/aiimages/31/636940.png "捕获“ socket.error：[Errno 111]连接被拒绝”异常")
通过捕获 所有
socket.error异常，并在
errno属性不等于111的情况下重新引发它。或者，更好的是，使用
errno.ECONNREFUSED常量代替：
import errnofrom socket import error as socket_errortry: 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
