python 的cookie处理操作

使用已有的cookie访问网站

import cookielib, urllib2

ckjar = cookielib.MozillaCookieJar(os.path.join(’C:\Documents and Settings\tom\Application Data\Mozilla\Firefox\Profiles\h5m61j1i.default’, ‘cookies.txt’))

req = urllib2.Request(url, postdata, header)

req.add_header(’User-Agent’, \

‘Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)’)

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(ckjar) )

f = opener.open(req)

htm = f.read()

f.close()

访问网站获得cookie，并把获得的cookie保存在cookie文件中

import cookielib, urllib2
req = urllib2.Request(url, postdata, header)

req.add_header(’User-Agent’, \

‘Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)’)
ckjar = cookielib.MozillaCookieJar(filename)

ckproc = urllib2.HTTPCookieProcessor(ckjar)
opener = urllib2.build_opener(ckproc)
f = opener.open(req)

htm = f.read()

f.close()
ckjar.save(ignore_discard=True, ignore_expires=True)

使用指定的参数生成cookie,并用这个cookie访问网站

import urllib.request as ur
import urllib.parse as up
#import http.cookiejar as cj
#coding:gbk

charset='utf8'

#组件信息
#cookiejar = cj.CookieJar()
#urlopener = ur.build_opener(ur.HTTPCookieProcessor(cookiejar))
urlopener = ur.build_opener(ur.HTTPCookieProcessor())
