windows7 python 指定源组播 10049_Windows Python多播上的错误10049

这是一些用于设置多播接收器的

Python代码.它在mac和linux上运行良好.

import socket,struct

ADDR=’239.239.250.1′

PORT=8001

sock = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

sock.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)

sock.bind((ADDR,PORT))

mreq = struct.pack(“4sl”,socket.inet_aton(ADDR),socket.INADDR_ANY)

sock.setsockopt(socket.IPPROTO_IP,socket.IP_ADD_MEMBERSHIP,mreq)

但在Windows上运行时在绑定上收到错误10049.

Z:\winx>c:\Python27\python.exe q2.py

Traceback (most recent call last):

File “q2.py”,line 11,in

sock.bind((ADDR,PORT))

File “c:\Python27\lib\socket.py”,line 224,in meth

return getattr(self._sock,name)(*args)

socket.error: [Errno 10049] The requested address is not valid in its context

Windows多播是否存在已知问题？如果没有,我可以采取哪些步骤进行诊断？
