python 的cookie處理操作

• 使用已有的cookie訪問網站

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()

• 訪問網站獲得cookie，並把獲得的cookie儲存在cookie檔案中

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)

• 使用指定的參數產生cookie,並用這個cookie訪問網站
