查看urllib2的源代码，看起来最简单的方法是将HTTPRedirectHandler子类化，然后使用build_opener覆盖默认的HTTPRedirectHandler，但这似乎需要很多(相对复杂的工作)来完成应有的工作很简单。

解决方案

Dive Into Python有很好的章节介绍如何使用urllib2进行重定向。另一个解决方案是httplib。

>>> import httplib
>>> conn = httplib.HTTPConnection("www.bogosoft.com")
>>> conn.request("GET", "")
>>> r1 = conn.getresponse()
>>> print r1.status, r1.reason
301 Moved Permanently
>>> print r1.getheader('Location')
http://www.bogosoft.com/new/location

我第二次将olt的指针指向Dive into Python。这是一个使用urllib2重定向处理程序的实现，比应做的工作还要多？也许，耸耸肩。

import sys
import urllib2

class RedirectHandler(urllib2.HTTPRedirectHandler):
    def http_error_301(self, req, fp, code, msg, headers):  
        result = urllib2.HTTPRedirectHandler.http_error_301( 
            self, req, fp, code, msg, headers)              
        result.status = code                                 
        raise Exception("Permanent Redirect: %s" % 301)

    def http_error_302(self, req, fp, code, msg, headers):
        result = urllib2.HTTPRedirectHandler.http_error_302(
            self, req, fp, code, msg, headers)              
        result.status = code                                
        raise Exception("Temporary Redirect: %s" % 302)

def main(script_name, url):
   opener = urllib2.build_opener(RedirectHandler)
   urllib2.install_opener(opener)
   print urllib2.urlopen(url).read()

if __name__ == "__main__":
    main(*sys.argv)

我想这会有所帮助

from httplib2 import Http
def get_html(uri,num_redirections=0): # put it as 0 for not to follow redirects
conn = Http()
return conn.request(uri,redirections=num_redirections)
