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。
视频演示效果如下:
程序的源码如下:
- 1.air_stations.py
- 2.airline_ticket.py
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:

airline_data = [
Fore.BLUE strs Fore.RESET,
Fore.BLUE item['fn'] Fore.RESET,
'\n'.join([Fore.YELLOW item['dpbn'] Fore.RESET,

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
