Python数据从入门到实践

用Python实现—携程机票查询

以前参考别人的代码,用Python做了一个12306命令行式的火车票查询工具,感觉还挺有意思的!于是自己又做了一个类似的——携程机票查询器。

携程官网查询的效果是这样的:

Python命令行界面查询的效果是这样的:

输入出发地、目的地、乘机日期,即可看到可选的航班、机场、出发到达时间、票价等信息。

视频演示效果:可以参考知乎,链接如下https://zhuanlan.zhihu.com/p/33148780

程序的源码如下:

1.air_stations.py

2.airline_ticket.py

#1.air_stations.py
import re
import os
import json
import requests
from pprint import pprint

url = 'http://webresource.c-ctrip.com/code/cquery/resource/address/flight/flight_new_poi_gb2312.js?CR_2017_07_18_00_00_00'
response = requests.get(url,verify=False)
station = re.findall(u'([\u4e00-\u9fa5]+)\(([A-Z]+)\)', response.text)
stations = dict(station)
pprint(stations,indent = 4)
#2.airline_ticket.py
#此程序可用于查询携程机票,查询需要指定出发日期、出发城市、目的城市!(模仿了12306火车订票查询程序)
import requests,json,os
from docopt import docopt
from prettytable import PrettyTable
from colorama import init,Fore
from air_stations import stations

fromCity = input('Please input the city you want leave :')
toCity = input('Please input the city you will arrive :')
tripDate = input('Please input the date(Example:2017-09-27) :')

init()
class TrainsCollection:
    header = '航空公司 航班 机场 时间 机票价格 机场建设费'.split()
    def __init__(self,airline_tickets):
        self.airline_tickets = airline_tickets

    @property
    def plains(self):
        #航空公司的总表没有找到,但是常见航空公司也不是很多就暂时用这个dict{air_company}来收集!
        #如果strs没有查询成功,则会返回一个KeyError,表示此dict中未找到目标航空公司,则会用其英文代码显示!
        air_company = {"G5":"华夏航空","9C":"春秋航空","MU":"东方航空","NS":"河北航空","HU":"海南航空","HO":"吉祥航空","CZ":"南方航空","FM":"上海航空","ZH":"深圳航空","MF":"厦门航空","CA":"中国国航","KN":"中国联航"}
        for item in self.airline_tickets:
            try:
                strs = air_company[item['alc']]
            except KeyError:
                strs = item['alc']
            airline_data = [
            Fore.BLUE + strs + Fore.RESET,
            Fore.BLUE + item['fn'] + Fore.RESET,
            '\n'.join([Fore.YELLOW + item['dpbn'] + Fore.RESET,
                       Fore.CYAN + item['apbn'] + Fore.RESET]),
            '\n'.join([Fore.YELLOW + item['dt'] + Fore.RESET,
                       Fore.CYAN + item['at'] + Fore.RESET]),
            item['lp'],
            item['tax'],
            ]
            yield airline_data

    def pretty_print(self):
        #PrettyTable()用于在屏幕上将查询到的航班信息表逐行打印到终端
        pt = PrettyTable()
        pt._set_field_names(self.header)
        for airline_data in self.plains:
            pt.add_row(airline_data)
        print(pt)

def doit():
    headers = {
        "Cookie":"自定义",
        "User-Agent": "自定义",
        }
    arguments = {
    'from':fromCity,
    'to':toCity,
    'date':tripDate
    }
    DCity1 = stations[arguments['from']]
    ACity1 = stations[arguments['to']]
    DDate1 = arguments['date']
    url = ("http://flights.ctrip.com/domesticsearch/search/SearchFirstRouteFlights?DCity1={}&ACity1={}&SearchType=S&DDate1={}").format(DCity1,ACity1,DDate1)
    try:
        r = requests.get(url,headers = headers,verify=False)
    except Exception as e:
        print(repr(e))
    print(url)
    airline_tickets = r.json()['fis']
    TrainsCollection(airline_tickets).pretty_print()

if __name__ == '__main__':
    doit()

其实,此小程序还可以拓展,譬如将查询记录存到本地电脑(txt格式、或者存到数据库里)或者更厉害的还可以设置定时自动查询;还可以设置查询到自动发邮箱提醒;还可以用Python的GUI库将此程序做成桌面软件的形式。。。。

学点编程,好处多多😋
