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': "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('Accept-Encoding','gzip, deflate');
    req.add_header('Connection','keep-live');

    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();
