<H2><A NAME=
"SECTION00132060000000000000000"></A><A NAME=
"cookielib-examples"></A>
The first example shows the most common usage of
<tt class=
"module">cookielib
</tt>:
<div class=
"verbatim"><pre>
import cookielib, urllib2
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
r = opener.open(
"http://example.com/")
This example illustrates how to open a URL using your Netscape,
Mozilla, or Lynx cookies (assumes
<span class=
"Unix">Unix
</span>/Netscape convention for
location of the cookies file):
<div class=
"verbatim"><pre>
import os, cookielib, urllib2
cj = cookielib.MozillaCookieJar()
cj.load(os.path.join(os.environ[
"HOME"],
".netscape/cookies.txt"))
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
r = opener.open(
"http://example.com/")
The next example illustrates the use of
<tt class=
"class">DefaultCookiePolicy
</tt>.
Turn on RFC
2965 cookies, be more strict about domains when setting
and returning Netscape cookies, and block some domains from setting
cookies or having them returned:
<div class=
"verbatim"><pre>
from cookielib import CookieJar, DefaultCookiePolicy
policy = DefaultCookiePolicy(
rfc2965=True, strict_ns_domain=Policy.DomainStrict,
blocked_domains=[
"ads.net",
".ads.net"])
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
r = opener.open(
"http://example.com/")
