學習python時的路障 - Urlopen錯誤10060

-1

我試圖進一步學習Python，但是我遇到了障礙。我無法使urllib2/urllib正常工作。如果我這樣做response = urllib2.urlopen('http://python.org/')我得到這個錯誤：學習python時的路障 - Urlopen錯誤10060

Traceback (most recent call last): 
    File "<pyshell#6>", line 1, in <module> 
    response = urllib2.urlopen('http://python.org/') 
    File "C:\Python27\lib\urllib2.py", line 126, in urlopen 
    return _opener.open(url, data, timeout) 
    File "C:\Python27\lib\urllib2.py", line 400, in open 
    response = self._open(req, data) 
    File "C:\Python27\lib\urllib2.py", line 418, in _open 
    '_open', req) 
    File "C:\Python27\lib\urllib2.py", line 378, in _call_chain 
    result = func(*args) 
    File "C:\Python27\lib\urllib2.py", line 1207, in http_open 
    return self.do_open(httplib.HTTPConnection, req) 
    File "C:\Python27\lib\urllib2.py", line 1177, in do_open 
    raise URLError(err) 
URLError: <urlopen error [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond>

即使像URL = "http://173.194.75.94"其次是f=urllib.urlopen(URL)給出了同樣的錯誤，所以它不是一個DNS問題。我落後於沒有代理或防火牆。除了我的Windows默認防火牆，它是一直被禁用的。即使如此，我添加了python和pythonw.exe到它是例外。

任何線索如何解決這個問題？

嘗試一些調試。使用自己的計算機向該站點發送ping。然後使用python爲您自己的計算機創建一個子進程，並向該站點發送一個ping。如果這工作，那麼它的python就是問題所在。這意味着python沒有權限訪問網絡。 imho –

顯然你是在防火牆或代理後面..... –

使用requests可以讓你的生活更輕鬆;

In [1]: import requests 

In [2]: pysite = requests.get('http://python.org/') 

In [3]: pysite.status_code 
Out[3]: 200 

In [4]: pysite.ok 
Out[4]: True 

In [5]: pysite.text[0:40] 
Out[5]: u'<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML' 

In [6]: pysite.error 

In [7]: pysite.links 
Out[7]: {} 

In [8]: pysite.reason 
Out[8]: 'OK'

當您嘗試訪問某個網站時，您仍然會收到例外情況。不存在或在您的網絡上被阻止：

In [3]: foobar = requests.get('http://foo.bar/')

但ConnectionError異常提供的信息告訴您發生了什麼;

In [8]: try:      
    foobar = requests.get('http://foo.bar/') 
except requests.ConnectionError as oops: 
    print oops.message 
    ...:  
[Errno 8] hostname nor servname provided, or not known
