通过python urllib2在HTTP标头中传递会话Cookie?
问题内容:
我正在尝试编写一个简单的脚本来登录Wikipedia,并使用Mediawiki
API在我的用户页面上执行一些操作。但是,我似乎从未超越过第一个登录请求(从此页面:https
:
//en.wikipedia.org/wiki/Wikipedia
:
Creating_a_bot#Logging_in)。我不认为正在发送我设置的会话cookie。到目前为止,这是我的代码:
import Cookie, urllib, urllib2, xml.etree.ElementTree
url = 'https://en.wikipedia.org/w/api.php?action=login&format=xml'
username = 'user'
password = 'password'
user_data = [('lgname', username), ('lgpassword', password)]
#Login step 1
#Make the POST request
request = urllib2.Request(url)
data = urllib.urlencode(user_data)
login_raw_data1 = urllib2.urlopen(request, data).read()
#Parse the XML for the login information
login_data1 = xml.etree.ElementTree.fromstring(login_raw_data1)
login_tag = login_data1.find('login')
token = login_tag.attrib['token']
cookieprefix = login_tag.attrib['cookieprefix']
sessionid = login_tag.attrib['sessionid']
#Set the cookies
cookie = Cookie.SimpleCookie()
cookie[cookieprefix + '_session'] = sessionid
#Login step 2
request = urllib2.Request(url)
session_cookie_header = cookieprefix+'_session='+sessionid+'; path=/; domain=.wikipedia.org; HttpOnly'
request.add_header('Set-Cookie', session_cookie_header)
user_data.append(('lgtoken', token))
data = urllib.urlencode(user_data)
login_raw_data2 = urllib2.urlopen(request, data).read()
我认为问题出在某处request.add_header('Set-Cookie', session_cookie_header)
,但我不确定。如何使用这些python库在每个请求中在标头中发送cookie(这对于许多API函数而言都是必需的)。
