Python-12306车票查询

个人训练需要类似这种从json提取多个信息

写完后发现可以满足自己查询车票的需求，所以加上了输入查询的功能

上代码:

import requests
import json
import re

url = 'https://kyfw.12306.cn/otn/leftTicket/query?leftTicketDTO.train_date=2019-05-09&leftTicketDTO.from_station=CQW&leftTicketDTO.to_station=GIW&purpose_codes=ADULT'

# 获取地名对应的代号
def get_name(name,headers):
    url = 'https://www.12306.cn/index/script/core/common/station_name_v10028.js'
    response = requests.get(url,headers = headers)
    res = re.findall(r'@.+?|(.+?)|(.+?)|',response.text)
    for i in res:
        if i[0] == name:
            return i[1]
    return None

# 将信息中的' '值转化为网页类似的那种'--'
def clear_info(list):
    for i in range(len(list)):
        if list[i] == '':
            list[i] = '--'
    return list

# 获取网页信息
def get_html(beg_name,st_name,time):
    url = 'https://kyfw.12306.cn/otn/leftTicket/query'

    params = {
        'leftTicketDTO.train_date': time,
        'leftTicketDTO.from_station': beg_name,
        'leftTicketDTO.to_station': st_name,
        'purpose_codes': 'ADULT'
    }

    response = requests.get(url, headers=headers, params=params)
    return response.text

headers = {
    'Cookie': 'JSESSIONID=696CD9155D2B8006B7881933C8CA25E8; _jc_save_wfdc_flag=dc; BIGipServerotn=921698826.50210.0000; RAIL_EXPIRATION=1557715740051; RAIL_DEVICEID=miUOG_8cGgit72oTyiFjYm7fe2HzLle69Ud1Pf7HgG-T9d8t7RkC1iBe3m0aLgz8Vtb-DOp-rsEWVoxAazt4euSyRznwBRGpnLLdja51hvo2cFeIGTK5ON8mMLldB_ZH3Hx3yXe5OCL_hcON4XpV3bmQt4VYNnd4; BIGipServerpool_passport=267190794.50215.0000; route=6f50b51faa11b987e576cdb301e545c4; _jc_save_fromDate=2019-05-09; _jc_save_toDate=2019-05-09; SL_GWPT_Show_Hide_tmp=1; SL_wptGlobTipTmp=1; _jc_save_fromStation=%u91CD%u5E86%2CCQW; _jc_save_toStation=%u8D35%u9633%2CGIW',

    response = get_html(beg_name, st_name, time)
    response = json.loads(response)
    adder = response['data']['map']
    res = response['data']['result']

    # 将需要的信息提出来
    for item in res:
        info = []
        item = item.split('|')
        info.append(item[3])
        info.append(adder[item[6]])
        info.append(adder[item[7]])
        info.append(item[8])
        info.append(item[9])
        info.append(item[10])

代码简单  没事练练手
