本文实例讲述了python代码写的12306订票代码，分享给大家供大家参考。

具体实现方法如下：

import datetime import json import re import sys import time import Image import PyV8 import requests import tools.email_helper as emailHelper reload(sys) sys.setdefaultencoding('utf-8') # @UndefinedVariable reqSingle = requests.Session() attCheCi=["G655","G6741","G67","G491"] #关注的车次 dateList=["2015-02-18"] #关注的日期 username="12306登录用户名" password="登录密码" #这个是需要手动提交订单后f12自己找的，挨个post请求去找，参数名为：oldPassengerStr 格式如下 oldPassengerStr="姓名,1,130434199802036011,1_姓名2,1,130434199204238069,1_" #这个是需要手动提交订单后f12自己找的，挨个post请求去找，参数名为：passengerTicketStr 格式如下
