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:

携程小程序机票预订(用Python实现携程机票查询)(1)

Python命令行界面查询的效果是这样的:

携程小程序机票预订(用Python实现携程机票查询)(2)

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。

视频演示效果如下:

程序的源码如下:

1.air_stations.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

#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
