本文实例讲述了Python模拟登录12306的方法。分享给大家供大家参考。

具体实现方法如下：

复制代码 代码如下:

#!/usr/bin/python

# -*- coding: utf-8 -*-

import re;

import sys;

import cookielib;

import urllib;

import urllib2;

import optparse;

import json;

import httplib2;

reload(sys)

sys.setdefaultencoding('utf8');

def Login():

cj = cookielib.CookieJar();

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj));

urllib2.install_opener(opener);

print "--------------[step1] to get cookie";

Url = "https://kyfw.12306.cn/otn/login/init";

resp = urllib2.urlopen(Url);

for index, cookie in enumerate(cj):

print '[',index, ']',cookie;

print "--------------[step2] to get code";

Url2 = "https://kyfw.12306.cn/otn/passcodeNew/getPassCodeNew?module=login&rand=sjrand";

resp2 = urllib2.urlopen(Url2);

#respInfo2 = resp2.info();

#print "respInfo=",respInfo2;

with open("code.png", "wb") as image:

image.write(resp2.read())

codeStr = sys.stdin.readline();

codeStr = codeStr[:-1]

print "--------------[step3] to check code";

ajax_url = "https://kyfw.12306.cn/otn/passcodeNew/checkRandCodeAnsyn";

dc = {

'randCode' : codeStr,

'rand' : "sjrand"

};

request = urllib2.Request(ajax_url, urllib.urlencode(dc))

request.add_header("Content-Type", "application/x-www-form-urlencoded; charset=utf-8")

request.add_header('X-Requested-With','XMLHttpRequest')

request.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36')

request.add_header('Referer','https://kyfw.12306.cn/otn/login/init')

request.add_header('Accept','*/*')

request.add_header('Accept-Encoding','gzip, deflate')

f = urllib2.urlopen(request)

print(f.read())

print "--------------[step4] to login";

LoginUrl = "http://kyfw.12306.cn/otn/login/loginAysnSuggest";

dc = {

'randCode' : codeStr,

'userDTO.password' : "sunyuke1989",

'loginUserDTO.user_name': "sunyuke@qq.com"

};

req = urllib2.Request(LoginUrl, urllib.urlencode(dc));

req.add_header('Content-Type', "application/x-www-form-urlencoded");

req.add_header('X-Requested-With','XMLHttpRequest');

req.add_header('Origin','https://kyfw.12306.cn');

req.add_header('Referer','https://kyfw.12306.cn/otn/login/init');

req.add_header('Accept','*/*');

req.add_header('Accept-Encoding','gzip, deflate');

req.add_header('Connection','keep-live');

request.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36')

resp = urllib2.urlopen(req);

print(resp.read().encode('gb18030'));

LoginingUrl = "https://kyfw.12306.cn/otn/login/userLogin";

req = urllib2.Request(LoginingUrl, "");

print "--------------[step5] to QueryUserInfo";

LoginingUrl = "https://kyfw.12306.cn/otn/modifyUser/initQueryUserInfo";

req = urllib2.Request(LoginingUrl, "");

resp = urllib2.urlopen(req);

info = resp.read();

print(resp.read().encode('gb18030'));

if __name__=="__main__":

Login();
