PYTHON实现12306余票查询-2018年3月7日有效

先开看下实现结果：源码：from prettytable import PrettyTableimport re,time,requests,jsonwith open(r'D:\PycharmProjects\12306\StationLib.txt', encoding='utf-8') as fp:patt = re.compile('\d+')data = patt.sub('',fp.read())list = re.findall(r'\d*@.+?(?=@)',data)AreaLib = {}AreaLib_Converse = {}for i in list:area = re.search(r'[\u4e00-\u9fa5]+',i)code = re.search(r'(?<=[^\x00-\xff]\|)\w+(?=\|)',i)AreaLib[area.group()] = code.group()AreaLib_Converse[code.group()] = area.group()try:from_station = AreaLib[input('出发地>:')]to_station = AreaLib[input('目的地>:')]except KeyError:print('地址不存在！')exit()train_date = input('出发时间(8位，默认今天)>:')train_date1 = '{}-{}-{}'.format(train_date[0:4],train_date[4:6],train_date[6:8])if train_date == '':train_date1 = time.strftime('%Y-%m-%d', time.localtime())url = "https://kyfw.12306.cn/otn/leftTicket/queryO?" \"leftTicketDTO.train_date={}&leftTicketDTO.from_station={}&leftTicketDTO.to_station={}" \"&purpose_codes=ADULT".format(train_date1,from_station,to_station)wb_data = requests.get(url)origindata = json.loads(wb_data.text)table = PrettyTable(["出发站","到达站","班次", "出发时间","到达时间","历时","V商务","V一等","V二等","软卧","硬卧","软座","硬座","无座"])for i in origindata['data']['result']:basedata = i.split('|')train_name = basedata[3]start_station = AreaLib_Converse[basedata[6]]end_station = AreaLib_Converse[basedata[7]]train_start = basedata[8]train_end = basedata[9]train_duration = basedata[10]Gte = basedata[25]Gyi = basedata[31]Ger = basedata[30]Kruanwo = basedata[23]Kyingwo = basedata[28]Kruanzuo = basedata[24]Kyingzuo = basedata[29]Kwuzuo = basedata[26]table.add_row([start_station,end_station,train_name,train_start,train_end,train_duration,Gte,Gyi,Ger,Kruanwo,Kyingwo,Kruanzuo,Kyingzuo,Kwuzuo])print(table)

最后，本代码依赖一个本地的车站代码对照表，对照表内容可以从‘https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version=1.9049’获取，复制下来存到txt直接能用。
