说明：python的urllib2获取网页(urlopen)会自动重定向（301,302）。但是，有时候我们需要获取302,301页面的状态信息。就必须获取到转向前的调试信息。
下面代码将可以做到避免302重定向到新的网页
#!/usr/bin/python

#encoding=utf-8

import urllib2
class RedirctHandler(urllib2.HTTPRedirectHandler):
"""docstring for RedirctHandler"""
def http_error_301(self, req, fp, code, msg, headers):
pass
def http_error_302(self, req, fp, code, msg, headers):
pass
def getUnRedirectUrl(url,timeout=10):
req = urllib2.Request(url)
debug_handler = urllib2.HTTPHandler(debuglevel = 1)
opener = urllib2.build_opener(debug_handler, RedirctHandler)
html = None
response = None
try:
response = opener.open(url,timeout=timeout)
html = response.read()
except urllib2.URLError as e:
if hasattr(e, 'code'):
error_info = e.code
elif hasattr(e, 'reason'):
error_info = e.reason
finally:
if response:
response.close()
if html:
return html
else:
return error_info
html = getUnRedirectUrl('http://jb51.net')
print html
