python - 捕捉“socket.error：[Errno 111] Connection denied”异常

Question

我怎么能捕捉到socket.error: [Errno 111] Connection refused异常？

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

Answer 1

通过捕获所有 异常，并在属性不等于 111socket.error时重新引发异常。或者，更好的是，使用常量代替：errnoerrno.ECONNREFUSED

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
