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
passengerTicketStr="O,0,1,姓名,1,130434199802036011,13683456789,N_O,0,1,姓名2,1,130434199204238069,13683456789,N"
