I'm trying to include two cookies when I use urllib2 to view a page.
#Code Start
import urllib2
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor())
opener.addheaders.append(("Cookie", "user=abcd"))
opener.addheaders.append(("Cookie", "password=12345"))
print opener.addheaders
r = opener.open("http://emhsoft.com/docs/cookies.php";)
print r.readlines()
#Code End
http://emhsoft.com/docs/cookies.php is live, and just includes
<?php print_r($_COOKIE); ?>
The output is
[('User-agent', 'Python-urllib/2.6'), ('Cookie', 'user=abcd'),
('Cookie', 'password=12345')]
['Array\n', '(\n', ' [user] => abcd\n', ')\n', ' ']
I expected both of the cookies to show up, not just one.
It is expected that all the cookies are contained within a single
header, e.g.:
opener.addheaders.append(("Cookie", "user=abcd; password=12345"))
You probably shouldn't be manually adding Cookie headers if you're using
HTTPCookieProcessor; they will tend to clobber each other. You could
add the cookies to the cookie jar object directly, although it's not
really designed for that use case. Better to just let the web app set
the cookies -- if you want to log in programmatically, pass the username
and password in the POST data, and then the web app can set whatever
cookies it wants to remember the session.
And in case you aren't aware, storing the user's password in a cookie is
generally considered bad form as it poses a greater security risk than
storing an opaque session token. That way the password need only be
sent across the wire once and cannot be discovered by inspecting the
user's browser cache.
Cheers,

Yes, this works. Thank you.
(I am aware of the cookie jar, and would normally use it. It just
wouldn't work well in this case. Also, the user/pass was just an
example, and *not* how I was going to do this.)
