urllib2

问题 I'm having a heck of a time getting asynchronous / threaded HTTPS requests to work using Python's urllib2. Does anyone out there have a basic example that implements urllib2.Request, urllib2.build_opener and a subclass of urllib2.HTTPSHandler? Thanks! 回答1: The code below does 7 http requests asynchronously at the same time. It does not use threads, instead it uses asynchronous networking with the twisted library. from twisted.web import client from twisted.internet import reactor, defer urls

问题 I cant really understand how youtube serves videos but I have been reading through what I can, it seems like the old method get_video is now obsolete and can't be used any more so because of this I am asking if there is another pythonic and simple method for collecting youtube videos. 回答1: You might have some luck with youtube-dl http://rg3.github.com/youtube-dl/documentation.html I'm not sure if there's a good API, but it's written in Python, so theoretically you could do something a little

问题 Update: see the comments for my solution. My python code uses urllib2 to access a FTP server through a proxy with user and password. I use both a urllib2.ProxyHandler and a urllib2.ProxyBasicAuthHandler to implement this by following urllib2 examples: 1 import urllib2 2 proxy_host = 'host.proxy.org:3128' # only host name, no scheme (http/ftp) 3 proxy_handler = urllib2.ProxyHandler({'ftp': proxy_host}) 4 proxy_auth_handler = urllib2.ProxyBasicAuthHandler() 5 proxy_auth_handler.add_password

问题 I am trying to write my first Python script, and with lots of Googling, I think that I am just about done. However, I will need some help getting myself across the finish line. I need to write a script that logs onto a cookie-enabled site, scrape a bunch of links, and then spawn a few processes to download the files. I have the program running in single-threaded, so I know that the code works. But, when I tried to create a pool of download workers, I ran into a wall. #manager.py import Fetch

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I would like to get the estimated results number from google for a keyword. Im using Python3.3 and try to accomplish this task with BeautifulSoup and urllib.request. This is my simple code so far def numResults(): try: page_google = '''http://www.google.de/#output=search&sclient=psy-ab&q=pokerbonus&oq=pokerbonus

问题 I am running a script using python that uses urllib2 to grab data from a weather api and display it on screen. I have had the problem that when I query the server, I get a "no address associated with hostname" error. I can view the output of the api with a web browser, and I can download the file with wget, but I have to force IPv4 to get it to work. Is it possible to force IPv4 in urllib2 when using urllib2.urlopen? 回答1: Not directly, no. So, what can you do? One possibility is to explicitly

问题 I've implemented a Pivotal Tracker API module in Python 2.7. The Pivotal Tracker API expects POST data to be an XML document and "application/xml" to be the content type. My code uses urlib/httplib to post the document as shown: request = urllib2.Request(self.url, xml_request.toxml('utf-8') if xml_request else None, self.headers) obj = parse_xml(self.opener.open(request)) This yields an exception when the XML text contains non-ASCII characters: File "/usr/lib/python2.7/httplib.py", line 951,

问题 I am having a strange situation: i am curling urls like this: def check_urlstatus(url): h = httplib2.Http() try: resp = h.request("http://" + url, 'HEAD') if int(resp[0]['status']) < 400: return 'ok' else: return 'bad' except httplib2.ServerNotFoundError: return 'bad' if I try to test this with: if check_urlstatus('.f.de') == "bad": #<--- error happening here #.. #.. it is saying: UnicodeError: label empty or too long what is the problem i am causing here? EDIT : here is the traceback with
