import urllib2
import urllib

url = "http://www.torn.com/authenticate.php"
username = raw_input("Your username; ")
password = raw_input("Your password: ")
query = {'player':username, 'password':password}
data_query = urllib.urlencode(query)
sending_data = urllib2.Request(url, data_query)
print sending_data()
response = urllib2.urlopen(sending_data)
print "You are currently logged unto to:", response.geturl()
print response.read()

如何实现cookielib来创建会话，请逐行解释谢谢

Answer 1

from cookielib import CookieJar

cj = CookieJar()
login_data = urllib.urlencode({'j_username' : username, 'j_password' : password})
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
opener.open("http://www.torn.com/authenticate.php", login_data)

首先，您要初始化CookieJar。然后编码您的凭据，因为它们需要以某种形式发送以供PHP服务器读取。然后你必须初始化一个开启者，它基本上是一个HTTP客户端，并配置它来使用你的CookieJar。然后将您的登录信息提交给服务器以创建会话并生成cookie。要继续使用这些Cookie，请使用opener.open()代替urllib2.urlopen（尽管您仍然可以使用urllib2.Request()生成请求。

Answer 2

您需要使用OpenerDirector。来自the documentation：

import cookielib, urllib2
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
r = opener.open("http://example.com/")

因此，为了传递数据，您的代码应如下所示：

import urllib2
import urllib
import cookielib

url = "http://www.torn.com/authenticate.php"
username = raw_input("Your username; ")
password = raw_input("Your password: ")
query = {'player':username, 'password':password}
data_query = urllib.urlencode(query)
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
response = opener.open(url, data_query)
print "You are currently logged unto to:", response.geturl()
print response.read()
