在使用urllib2.urlopen函数的时候发现老是出现下面的错误:
urllib2.URLError: <urlopen error (-2, 'Name or service not known')>
甚至使用python的命令运行模式下也有这个问题，请问这个问题该怎么解决？
>>> req = urllib2.Request('http://www.voidspace.org.uk')
>>> response = urllib2.urlopen(req)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/urllib2.py", line 124, in urlopen
return _opener.open(url, data)
File "/usr/lib/python2.5/urllib2.py", line 381, in open
response = self._open(req, data)
File "/usr/lib/python2.5/urllib2.py", line 399, in _open
'_open', req)
File "/usr/lib/python2.5/urllib2.py", line 360, in _call_chain
result = func(*args)
File "/usr/lib/python2.5/urllib2.py", line 1107, in http_open
return self.do_open(httplib.HTTPConnection, req)
File "/usr/lib/python2.5/urllib2.py", line 1082, in do_open
raise URLError(err)
urllib2.URLError: <urlopen error (-2, 'Name or service not known')>
注：
使用编辑器运行都没有问题的!
