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(\’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(\’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();
