send cookie on request with urllib2
Hi, I dont understand why this is so complicated, just to add one line of cookie header on the GET request. This is my unworking code: import time import Cookie import cookielib, urllib2 c= cookielib.Cookie(1,"Name","Tom", 80,False, "itay", False, False, "d:\\asddd",False, False,time.time()+1000,False,None,None,None) cj = cookielib.CookieJar() cj.set_cookie(c) opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj)) opener.open(r'http://itay/temp.html";) why this isn't working? Itay is my computer name. it is an IIS server too. the code is running, but i dont see any cookie that attached to the GET request. thanks alot! -- http://mail.python.org/mailman/listinfo/python-list

You haven't said what you're really trying to do.

Constructing your own Cookie instances is rarely necessary or
sensible. If you do, I recommend getting the constructor arguments by
inspecting the Cookie object the server actually returns, rather than
using the values you *think* you know are correct.

Please define "working".
If you want to handle cookies when opening URLs, just do this:
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor())
opener.open("http://itay/temp.html";)
# more .open() calls go here...
Of course, on the first HTTP request, cookie handling cannot have any
effect at all unless you've somehow loaded some old cookies first.
Your .open() may only involve a single HTTP request (though
server-side software may detect the absence of a cookie on the first
request, and do a page refresh or redirect so it can see its cookie
returned to it again; vanilla urllib2 handles redirects but not
refreshes; package ClientCookie handles the latter, amongst other
things).
Regardless, turning on cookielib and httplib debug output will likely
be helpful if you're stuck (if only to post the output to this
newsgroup):
import logging, urllib2, sys
hh = urllib2.HTTPHandler()
hsh = urllib2.HTTPSHandler()
hh.set_http_debuglevel(1)
hsh.set_http_debuglevel(1)
opener = urllib2.build_opener(hh, hsh, urllib2.HTTPCookieProcessor())
logger = logging.getLogger("cookielib")
logger.addHandler(logging.StreamHandler(sys.stdout))
logger.setLevel(logging.DEBUG)
response = opener.open("http://wwwsearch.sf.net/cgi-bin/cookietest.cgi";)

Try '/'. """ "No," scolded Yoda. "Do, or do not. There is no try." """ (there, a Star Wars quote -- I guess there's truly no hope of ever erasing my geek status now!-) Why guess? Why not log in (using Python) and see what the cookie actually is? Once you've actually done that, there's nothing to stop you storing it as a Cookie constructor call. I know I certainly don't remember all the *truly horrendous* detail of what *exactly* all those parameters mean :-) The Cookie object, as is documented, is merely a struct object and it is easy to construct incorrect and even self-inconsistent Cookie objects; CookieJar has all the knowledge about constructing cookies -- and allows use of that knowledge through .make_cookies() and .load()/.revert().

Re: send cookie on request with urllib2
ok. i will explain what exactly i wanna do. i want to simulate the following client-side script with python: document.cookie="name=tom"; document.images["Pic"].src="temp2.html" what that happen here, is when this page loading, the browser loads "temp2.html" with HTTP header: Cookie: name=tom; this cookie does not come for the server, this is temporary cookie that sending from the client to the server. this cookie doesnt save on disk at all. is it possible to implements this at python?? -- http://mail.python.org/mailman/listinfo/python-list

In which case what you're trying to do is a reasonable hack, but better (UNTESTED): import urllib2, cookielib cj = cookielib.CookieJar opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj)) request = urllib2.Request(url) response = opener.open(request) response["Set-Cookie"] = "name=tom" cj.extract_cookies(response, request) If you have HTML-parsing code to extract these JS cookies that you want to run on every request (e.g. so even cookies set by JS during redirections get handled), you can make all this transparent very easily by using a handler similar to HTTPCookieProcessor itself (using a recent version of package ClientCookie here for (a recent version of) the response_seek_wrapper class) UNTESTED: import urllib2, cookielib class JSHTTPCookieProcessor(urllib2.BaseHandler): handler_order = 400 # before HTTPCookieProcessor def process_response(self, request, response): from ClientCookie import response_seek_wrapper if not hasattr(response, "seek"): response = response_seek_wrapper(response) try: name, value = get_js_cookie(response) # your ugly HTML parsing code here ;-) finally: response.seek(0) response["Set-Cookie"] = "%s=%s" % (name, value) return response opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(), JSHTTPCookieProcessor()) response = opener.open(url) # now we're handling JS cookies transparently!
