我有以下ZMQ脚本

#!/usr/bin/env python2.6


import signal
import sys
import zmq


context = zmq.Context()
socket = context.socket(zmq.SUB)

def signal_term_handler(signal, fname):
    socket.close()
    sys.exit(0)

def main():
    signal.signal(signal.SIGTERM, signal_term_handler)

    socket.connect('tcp://16.160.163.27:8888')
    socket.setsockopt(zmq.SUBSCRIBE, '')
    print 'Waiting for a message'

    while True:
        (event, params) = socket.recv().split()
        # ... doing something with that data ...

if __name__ == '__main__':
    main()

当我按Ctrl-C时,出现以下错误：

Traceback (most recent call last):
  File "./nag.py", line 28, in <module>
    main()
  File "./nag.py", line 24, in main
    (event, params) = socket.recv().split()
  File "socket.pyx", line 628, in zmq.backend.cython.socket.Socket.recv (zmq/backend/cython/socket.c:5616)

  File "checkrc.pxd", line 11, in zmq.backend.cython.checkrc._check_rc (zmq/backend/cython/socket.c:5863)
KeyboardInterrupt

现在,我以为我处理了套接字的关闭,当收到用户的终止信号时,还不错,那我为什么收到这个丑陋的消息.我想念什么.

请注意,我已经在Google和*上进行了一些搜索,但未找到任何可解决此问题的方法.

谢谢.

编辑对于迄今为止的任何人-user3666197提出了一种非常好用的方法来处理执行过程中的终止或任何异常.

解决方法:

事件处理方法

尽管演示代码很小,但实际系统中,多主机/多进程通信系统越多,通常应在其主控制循环中处理所有不利影响的事件.

try:
    context = zmq.Context()         # setup central Context instance
    socket  = ...                   # instantiate/configure all messaging archetypes
    # main control-loop ----------- # ----------------------------------------
    #
    # your app goes here, incl. all nested event-handling & failure-resilience
    # ----------------------------- # ----------------------------------------
except ...:
    #                               # handle IOErrors, context-raised exceptions
except Keyboard Interrupt:
    #                               # handle UI-SIG
except:
    #                               # handle other, exceptions "un-handled" above
finally:
    #                               # GRACEFULL TERMINATION
    # .setsockopt( zmq.LINGER, 0 )  #           to avoid hanging infinitely
    # .close()                      # .close()  for all sockets & devices
    #
    context.term()                  #           Terminate Context before exit
