urllib.urlretrieve处理网上视频问题

在网上抓取一串视频链接后，想用urllib.urlretrieve方式来保存视频到本地，但出现了以下问题：

  File "C:\Python27_x86\lib\httplib.py", line 415, in begin
    version, status, reason = self._read_status()
  File "C:\Python27_x86\lib\httplib.py", line 371, in _read_status
    line = self.fp.readline(_MAXLINE + 1)
  File "C:\Python27_x86\lib\socket.py", line 476, in readline
    data = self._sock.recv(self._rbufsize)
IOError: [Errno socket error] [Errno 10054] 

保存下载视频的方式：

urllib.urlretrieve(video_down_url,'%s.mp4' %video_title)
