I am trying to create a download progress bar in python using the urllib2 http client. I've looked through the API (and on google) and it seems that urllib2 does not allow you to register progress hooks. However the older deprecated urllib does have this functionality. Does anyone know how to create a progress bar or reporting hook usin...
After reading through the other questions on StackOverflow, I got a snippet of Python code that is able to make requests through a Tor proxy: import urllib2 proxy = urllib2.ProxyHandler({'http':'127.0.0.1:8118'}) opener = urllib2.build_opener(proxy) print opener.open('https://check.torproject.org/').read() Since Tor works fine in Fir...
The urllib2 documentation says that timeout parameter was added in Python 2.6. Unfortunately my code base has been running on Python 2.5 and 2.4 platforms. Is there any alternate way to simulate the timeout? All I want to do is allow the code to talk the remote server for a fixed amount of time. Perhaps any alternative built-in library...
I would like to fetch certain .html files from a web server. My intention is to fetch .html files from a web site (http://www.thetabworld.com/) that has a word "metallica" on file name. How is that possible using python? I have heard about urllib2 but as a python noob, I don't have a slightest idea how to use it. ...
I have extensive experience with PHP cURL but for the last few months I've been coding primarily in Java, utilizing the HttpClient library. My new project requires me to use Python, once again putting me at the crossroads of seemingly comparable libraries: pycurl and urllib2. Putting aside my previous experience with PHP cURL, what is ...
I set up a process that read a queue for incoming urls to download but when urllib2 open a connection the system hangs. import urllib2, multiprocessing from threading import Thread from Queue import Queue from multiprocessing import Queue as ProcessQueue, Process def download(url): """Download a page from an url. url [str]: url...
I'm making a python URL grabber program. For my purposes, I want it to time out really really fast, so I'm doing urllib2.urlopen("http://.../", timeout=2) Of course it times out correctly as it should. However, it doesn't bother to close the connection to the server, so the server thinks the client is still connected. How can I ask url...

Hi, I am bit confuse over set of libraries of pythons to connect with REST enabled web services. I have tried httplib, urllib and urllib2. I want to know how can methods like PUT, GET, POST, DELETE can be achieved using this library. Regards, Parthiv ...
I thought that a post sent all the information in HTTP headers when you used post (I'm not well informed on this subject obviously), so I'm confused why you have to urlencode() the data to a key=value&key2=value2 format. How does that formatting come into play when using POST?: # Fail data = {'name': 'John Smith'} urllib2.urlopen(foo_ur...
I am trying to screen scrape multiple pages of a website, that return an 'HTTP Error 500: Internal Server Error' response, but still give important data inside the error HTML. Normally, I would fetch a page using this (Python 2.6.4): import urllib2 url = "http://google.com" data = urllib2.urlopen(url) data = data.read() But when atte...
I'd like to tell urllib2.urlopen (or a custom opener) to use 127.0.0.1 (or ::1) to resolve addresses. I wouldn't change my /etc/resolv.conf, however. One possible solution is to use a tool like dnspython to query addresses and httplib to build a custom url opener. I'd prefer telling urlopen to use a custom nameserver though. Any suggest...
This afternoon I spent several hours trying to find a bug in my custom extension to urllib2.Request. The problem was, as I found out, the usage of super(ExtendedRequest, self), since urllib2.Request is (I'm on Python 2.5) still an old style class, where the use of super() is not possible. The most obvious way to create a new class with ...
I am using urllib2 and HTTPCookieProcessor to login to a website. I want to login to multiple accounts concurrently and store the cookies to be reused later. Can you recommend an approach or library to achieve this? ...
I've got a piece of code that I can't figure out how to unit test! The module pulls content from external XML feeds (twitter, flickr, youtube, etc.) with urllib2. Here's some pseudo-code for it: params = (url, urlencode(data),) if data else (url,) req = Request(*params) response = urlopen(req) #check headers, content-length, etc... #par...

Python's urllib2 follows 3xx redirects to get the final content. Is there a way to make urllib2 (or some other library such as httplib2) also follow meta refreshes? Or do I need to parse the HTML manually for the refresh meta tags? ...
