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://phpno.com‘)

print html
