Python模拟登录12306的方法

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：

#!/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('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': "[e-mail]"

    };

    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');

    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();
