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();
