python - 在 Python 中，urllib2 给出错误

Question

我试过运行这个，

>>> urllib2.urlopen('http://tycho.usno.navy.mil/cgi-bin/timer.pl')

但是出现这样的错误，谁能告诉我解决方案？

Traceback (most recent call last):
  File "<pyshell#11>", line 1, in <module>
    urllib2.urlopen('http://tycho.usno.navy.mil/cgi-bin/timer.pl')
  File "C:\Python26\lib\urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "C:\Python26\lib\urllib2.py", line 391, in open
    response = self._open(req, data)
  File "C:\Python26\lib\urllib2.py", line 409, in _open
    '_open', req)
  File "C:\Python26\lib\urllib2.py", line 369, in _call_chain
    result = func(*args)
  File "C:\Python26\lib\urllib2.py", line 1161, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "C:\Python26\lib\urllib2.py", line 1136, in do_open
    raise URLError(err)
URLError: <urlopen error [Errno 11001] getaddrinfo failed>

仔细检查域是否可访问。

目前，我在域 - tycho.usno.navy.mil 收到 504 网关超时错误。

看起来该网站已关闭，也 downforeveryoneorjustme.com 说

It's not just you! http://tycho.usno.navy.mil looks down from here.

这就是为什么 getaddrinfo 失败了
