前言

今天教大家用Python制作一个12306查票程序脚本（仅供学习参考）

首先，先导入本次所需的模块

代码语言：javascript复制
import requests
import pandas as pd

import json

请求数据

找到数据来源

代码语言：javascript复制
url = 'https://kyfw.12306.cn/otn/leftTicket/query'
data = {
    'leftTicketDTO.train_date': train_date,
    'leftTicketDTO.from_station': city_json[from_station],
    'leftTicketDTO.to_station': city_json[to_station],
    'purpose_codes': 'ADULT',
}
headers = {
    'Cookie': '_uab_collina=163108019860709243490927; JSESSIONID=3A879F34238B594124705B10D7C0B0E6; BIGipServerotn=3956736266.64545.0000; guidesStatus=off; highContrastMode=defaltMode; cursorStatus=off; BIGipServerpassport=870842634.50215.0000; RAIL_EXPIRATION=1631354049020; RAIL_DEVICEID=jY49UGp1PWZZ0cY6CWj2wmKFDH60qsPXbu7L4D2DjNDJSM4sbqZmmlUm62-6L3k9SNtBAUgBPn7Rh1-FAxka97-nHNpT3QIh5YIXtw3mGao0mjLNkIv2ayvwqxWyFhdbos5_ziUA3XVil7awDZ0EjzKBAWdl22Hu; route=495c805987d0f5c8c84b14f60212447d; _jc_save_fromStation=长沙,CSQ; _jc_save_fromDate=2021-09-08; _jc_save_toDate=2021-09-08; _jc_save_wfdc_flag=dc; _jc_save_toStation=岳阳东,YIQ',

}
response = requests.get(url=url, params=data, headers=headers)

自动识别编码

代码语言：javascript复制
response.encoding = response.apparent_encoding

数据解析取值

代码语言：javascript复制
    for index in result:
        # requests.utils.unquote(index)
        index_list = index.replace('有', 'Yes').replace('无', 'No').split('|')
        # print(index_list)
        train_number = index_list[3]  # 车次
        if 'G' in train_number:
            time_1 = index_list[8]  # 出发时间
            time_2 = index_list[9]  # 到达时间
            prince_seat = index_list[32]  # 特等座
            first_class_seat = index_list[31]  # 一等座
            second_class = index_list[30]  # 二等座
            dit = {
                'Num': train_number,
                'Start': time_1,
                'End': time_2,
                'Top': prince_seat,
                'First': prince_seat,
                'Second': second_class,
                'Yz': '-',

            }
        else:
            time_1 = index_list[8]  # 出发时间
            time_2 = index_list[9]  # 到达时间
            hard_seat = index_list[29]  # 硬座
            no_seat = index_list[26]  # 无座
            soft_sleeper = index_list[23]  # 软卧
            hard_sleeper = index_list[28]  # 硬卧
            dit = {

                'Rw': soft_sleeper,
                'Yw': hard_sleeper,
            }
        lis.append(dit)
    content = pd.DataFrame(lis)
    print(content)

实现查询一座城市车次数据

实现全国车次查询

代码语言：javascript复制
f = open('city.json', mode='r', encoding='utf-8')
text = f.read()
city_json = json.loads(text)
while True:
    from_station = input('请输入你出发的城市：')
    to_station = input('请输入你达到的城市：')
    train_date = input('请输入乘车时间(2021-09-08/年-月-日)：')

再次查询/退出

代码语言：javascript复制
again = input('是否继续查询(Y/N): ')
if again == 'Y' or again == 'y':
    continue
else:
    break
