无法解开bit.ly网址？

我使用计算器this后的代码unshorten网址...无法解开bit.ly网址？

import httplib 
import urlparse 

def unshorten_url(url): 
    parsed = urlparse.urlparse(url) 
    h = httplib.HTTPConnection(parsed.netloc) 
    resource = parsed.path 
    if parsed.query != "": 
     resource += "?" + parsed.query 
    h.request('HEAD', resource) 
    response = h.getresponse() 
    if response.status/100 == 3 and response.getheader('Location'): 
     return unshorten_url(response.getheader('Location')) # changed to process chains of short urls 
    else: 
     return url

所有缩短链接bit.ly的新创建的URL unshortned“CEPT。

我得到这个错误：

>>> unshorten_url("bit.ly/1atTViN") 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "<stdin>", line 7, in unshorten_url

    raise err

是怎么回事？

你忘了包括URL方案：

unshorten_url("http://bit.ly/1atTViN")

注意http://那里，那是重要。没有它，网址是不正确解析：

>>> import urlparse 
>>> urlparse.urlparse('bit.ly/1atTViN') 
ParseResult(scheme='', netloc='', path='bit.ly/1atTViN', params='', query='', fragment='') 
>>> urlparse.urlparse('http://bit.ly/1atTViN') 
ParseResult(scheme='http', netloc='bit.ly', path='/1atTViN', params='', query='', fragment='')

查看如何当不包括http://的netloc参数为空;你最终试图连接到你自己的机器，而你没有运行网络服务器，因此连接被拒绝。

哇！非常感谢你。非常有意义。 – sirvon

可能bit.ly拒绝来自httplib等工具的连接。你可以尝试改变用户代理是这样的：

h.putheader('User-Agent','Mozilla/5.0 (X11; U; Linux i686; pl-PL; rv:1.7.10) Gecko/20050717 Firefox/1.0.6')
