Examples of code that uses URLLIB2 to prevent 302 jumps in Python

Description: Python's urllib2 Fetch Web page (urlopen) is automatically redirected (301,302). However, sometimes we need to get status information for 302,301 pages. You must obtain the debug information before turning.

The following code will be able to avoid 302 redirects to the new Web page

#!/usr/bin/python#-*-coding:utf-8-*-#encoding =utf-8#filename:states_code.py 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
