爬虫之爬取车票信息

使用charles抓包软件，抓取手机APP全国汽车票的数据并实现查找车票的功能

关于charles使用可以参考https://blog.csdn.net/smalCat/article/details/79817398

手机和电脑配置好charles后，打开APP全国汽车票软件即可在charles看到抓包的数据

在APP在上搜索车票信息时，发现多出一个链接（这里面很可能就有我们想要的车票信息）
抓取看看（里面的数据是unicode编码格式，注意要用unicode_escape来解码）
果然这里面有所有的车票信息，之后我发现这个URL包含了出发地址，终点地址和时间的信息。

这样我们就可以通过修改URL来准确的获取我们想要的车票信息达到基本查票功能，代码如下
这样的数据%E6%B7%B1%E5%9C%B3可以用urllib.parse.quote来解码

import requests
import urllib
from urllib import parse
import json
import random


year = input("请输入年份")
month = input("请输入月份")
day = input("请输入日")

FromCity = input("请输入出发城市")
urllib.parse.unquote(FromCity)

ToCity = input("请输入终点城市")
urllib.parse.unquote(ToCity)

url = "http://gateway.qiche.tieyou.com/index.php?toCity="+str(ToCity)+"&fromDate="+str(year)+"-"+str(month)+"-"+str(day)+"&fromCity="+str(FromCity)+"&isForcedDSearch=0&isForcedASearch=0&method=product.getBusList&v=1.0¶m=%2Fapi%2Fhome&reqTime=1577164432&partner=tieyou_bus&version=20170610&channel=12308_apple_ios&ref=tieyou.app&n_app_v=8.1.8&basic_params=%7B%22app%22%3A%22bus_12308%22%2C%22big_channel%22%3A%2212308%22%2C%22smallchannel%22%3A%2212308_apple_ios%22%2C%22operat_system%22%3A%22ios%22%2C%22big_client_type%22%3A%22app%22%2C%22client_version%22%3A%221.00.002%22%7D"
