解析车站信息以及车辆信息
- 了解 解析车站信息
- 了解 解析车辆信息
1. 解析城市/车站编码
城市/车站编码js文件有版本号
# 12306.funk12306.get_stations_dict
import re
import json
import requests
# 获取车站编号字符串 station_version=1.9076
url = 'https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version=1.9076'
resp = requests.get(url)
stations_str = re.search("'(.*)'", resp.text).group(1)
# 获取{城市(车站):编码, ...} 键值对
stations_dict = {}
for station in stations_str.split('@'):
if station == '': # 按@切会切出空字符串
continue
stations_dict[station.split('|')[1]] = station.split('|')[2]
with open('./utils/stations_dict.py', 'w', encoding='utf8') as f:
f.write('stations_dict = ')
json.dump(stations_dict, f, ensure_ascii=False, indent=4)
2. 获取车辆信息
# 12306.funk12306.Funk12306.buy_ticket
def buy_ticket(self):
self.s.headers.pop('Referer') # 清除referer
# 获取城市(车站)编码
from_station = input('输入出发城市或车站:')
to_station = input('输入到达城市或车站:')
train_date = input('输入出行日期,格式为2018-12-03:')
from_station_code = stations_dict.get(from_station, '')
to_station_code = stations_dict.get(to_station, '')
# 查询车量信息日志get
url = 'https://kyfw.12306.cn/otn/leftTicket/log?leftTicketDTO.train_date=%s&leftTicketDTO.from_station=%s&leftTicketDTO.to_station=%s&purpose_codes=ADULT' % (train_date, from_station_code, to_station_code)
resp = self.s.get(url)
print(resp.text)
# 查询车量具体信息query
url = 'https://kyfw.12306.cn/otn/leftTicket/query?leftTicketDTO.train_date=%s&leftTicketDTO.from_station=%s&leftTicketDTO.to_station=%s&purpose_codes=ADULT' % (train_date, from_station_code, to_station_code)
response = self.s.get(url)
# 打印trains_list
print(json.loads(response.content)['data']['result'])
3. 解析车辆信息
# 12306.utils.parse_trains_infos
import urllib.parse
def parseTrainsInfos(trains_list):
"""
解析列车信息列表, 返回列车信息列表
"""
trains_infos_list = []
if trains_list == []:
return []
for train_info in trains_list:
train_info_list = train_info.split('|')
train_info_dict = {}
# 构造列车信息
train_info_dict['secretStr'] = urllib.parse.unquote(train_info_list[0]) # secretStr ;为''时无法购买车票
# train_info_list[1] 预定/列车停运
train_info_dict['train_no'] = urllib.parse.unquote(train_info_list[2]) # train_no
train_info_dict['stationTrainCode'] = urllib.parse.unquote(train_info_list[3]) # stationTrainCode 即车次 # 展示
train_info_dict['start_station'] = urllib.parse.unquote(train_info_list[4]) # 始发站 # 展示
train_info_dict['end_station'] = urllib.parse.unquote(train_info_list[5]) # 终点站 # 展示
train_info_dict['from_station'] = urllib.parse.unquote(train_info_list[6]) # 出发站 # 展示
train_info_dict['to_station'] = urllib.parse.unquote(train_info_list[7]) # 到达站 # 展示
train_info_dict['from_time'] = urllib.parse.unquote(train_info_list[8]) # 出发时间 # 展示
train_info_dict['to_time'] = urllib.parse.unquote(train_info_list[9]) # 到达时间 # 展示
train_info_dict['use_time'] = urllib.parse.unquote(train_info_list[10]) # 时长 # 展示
train_info_dict['buy_able'] = urllib.parse.unquote(train_info_list[11]) # 能否购买 Y 可以购买 N 不可以购买 IS_TIME_NOT_BUY 停运 # 展示
train_info_dict['leftTicket'] = urllib.parse.unquote(train_info_list[12]) # leftTicket
train_info_dict['start_time'] = urllib.parse.unquote(train_info_list[13]) # 车次始发日期 # 展示
train_info_dict['train_location'] = urllib.parse.unquote(train_info_list[15]) # train_location 不知道是啥??
train_info_dict['from_station_no'] = urllib.parse.unquote(train_info_list[16]) # 出发站编号
train_info_dict['to_station_no'] = urllib.parse.unquote(train_info_list[17]) # 到达站编号
# 14,18,19,20,27,34,35未知
train_info_dict['gaojiruanwo'] = urllib.parse.unquote(train_info_list[21]) # 高级软卧 # 展示
train_info_dict['qita'] = urllib.parse.unquote(train_info_list[22]) # 其他 # 展示
train_info_dict['ruanwo'] = urllib.parse.unquote(train_info_list[23]) # 软卧 # 展示
train_info_dict['ruanzuo'] = urllib.parse.unquote(train_info_list[24]) # 软座 # 展示
train_info_dict['tedengzuo'] = urllib.parse.unquote(train_info_list[25]) # 特等座 # 展示
train_info_dict['wuzuo'] = urllib.parse.unquote(train_info_list[26]) # 无座 # 展示
train_info_dict['yingwo'] = urllib.parse.unquote(train_info_list[28]) # 硬卧 # 展示
train_info_dict['yingzuo'] = urllib.parse.unquote(train_info_list[29]) # 硬座 # 展示
train_info_dict['erdengzuo'] = urllib.parse.unquote(train_info_list[30]) # 二等座 # 展示
train_info_dict['yidengzuo'] = urllib.parse.unquote(train_info_list[31]) # 一等座 # 展示
train_info_dict['shangwuzuo'] = urllib.parse.unquote(train_info_list[32]) # 商务座 # 展示
train_info_dict['dongwo'] = urllib.parse.unquote(train_info_list[33]) # 动卧 # 展示
trains_infos_list.append(train_info_dict)
return trains_infos_list
4. 获取后续请求所需的参数
# 12306.funk12306.Funk12306.buy_ticket
# 解析获取trains_list
trains_list = parseTrainsInfos(json.loads(response.content)['data']['result'])
print('查询的列车信息如下:')
pprint(trains_list)
# 获取选择的列车
train_info_dict = trains_list[int(input('请输入选中车次的下标:'))]
print('选中了列车信息为:')
pprint(train_info_dict)
# 列车信息
secretStr = train_info_dict['secretStr']
leftTicket = train_info_dict['leftTicket']
train_location = train_info_dict['train_location']
