Python中如何从火车余票查询到打造抢Supreme神器

今天就跟大家聊聊有关Python中如何从火车余票查询到打造抢Supreme神器，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

0x00 前言

一个AJ1联名OFF-White的鞋原价1399，炒卖价已经到了1w+(其实我也是个SneakerHead)以下是我近期的交易记录(拿来装X的)，很扎心.....But，现在都是抽签，跟抢貌似无关，就不写SneakerBot了...

再附上我在NIKE美国官网中签截图吧，听说Bred Toe还上了热搜，啊哈哈

所以就有了本篇文章吧....
强调一下，本文的主要目的就是抢东西，从火车余票查询，到打造一个抢Supreme的BOT吧。。而这一切都是基于Python

0x01 火车余票查询

之前回家，不少人为了火车票发愁......

所以，就有了本小节文章....监控火车余票...

本次环境是：Python2.7+deepinlinux

因为Windows编码问题多的我想打人，所以就换了linux

实现完的效果是这样的

咱们分步写

https://kyfw.12306.cn/otn/leftTicket/init，抓包

这是一个Get请求....所以看下这个url

https://kyfw.12306.cn/otn/leftTi ... purpose_codes=ADULT

train_date参数后面是时间

from_station参数后是起点站

to_station参数后是到达站

分析了这些之后，就可以通过Python来实现这个url了

这里呢，有个问题，像这些城市地点的英文在哪获取，通过F12大法，发现在这

https://kyfw.12306.cn/otn/resour ... tion_version=1.9047

我事先爬好了这些，在这里感谢一下Onise表哥@0nise，为了保证代码的美观性吧，所以我就import它了

先获取页面内容，

# -*- coding: utf-8 -*-import requestsfrom stations import stationsdef Get_train_text():    from_station = stations.get(raw_input('Please enter where you are from:'))    to_station = stations.get(raw_input('Please enter where you want to go:'))    date = raw_input('Please enter the date you want to inquire:')    url = ('https://kyfw.12306.cn/otn/leftTicket/queryZ?'          'leftTicketDTO.train_date={}&'          'leftTicketDTO.from_station={}&'          'leftTicketDTO.to_station={}&'          'purpose_codes=ADULT').format(date,from_station,to_station)           r=requests.get(url)    trains_text = r.json()['data']['result']    print trains_textif __name__ == '__main__':    Get_train_text()

然后for循环...

def Get_train_information():[/size][size=3]    for raw_train in Get_train_text():[/size][size=3]        print raw_train

然后观察一下

这样就很明朗了吧...

def Get_train_information():    key_list = []    value_list = []    for key,value in stations.items():        key_list.append(key)        value_list.append(value)    for raw_train in Get_train_text():        data_list = raw_train.split('|')        train_number = data_list[3]  #车次        from_station_code = data_list[6]  #始发站信息        to_station_code = data_list[7] #终点站信息        from_station_index = value_list.index(from_station_code)        to_station_index = value_list.index(to_station_code)        from_station_name = key_list[from_station_index]        to_station_name = key_list[to_station_index]         start_time = data_list[8] #出发时间        arrive_time = data_list[9]  #到达时间        time_duration = data_list[10]  #历时        first_class_seat = data_list[31] #一等座        second_class_seat = data_list[30] #二等座        soft_sleep = data_list[23] or '--' #软卧        hard_sleep = data_list[28] or '--'  #硬卧        hard_seat= data_list[29] or '--' #硬座        no_seat = data_list[26] or '--'  #无座

大概就是这样，然后让这些可观，就要用到PrettyTable了

pip install prettytable

# -*- coding: utf-8 -*-import requestsfrom stations import stationsfrom prettytable import PrettyTabledef Get_train_text():    from_station = stations.get(raw_input('Please enter where you are from:'))    to_station = stations.get(raw_input('Please enter where you want to go:'))    date = raw_input('Please enter the date you want to inquire:')    url = ('https://kyfw.12306.cn/otn/leftTicket/queryZ?'          'leftTicketDTO.train_date={}&'          'leftTicketDTO.from_station={}&'          'leftTicketDTO.to_station={}&'          'purpose_codes=ADULT').format(date,from_station,to_station)           r=requests.get(url)    trains_text = r.json()['data']['result']    return trains_textdef Get_train_information():    key_list = []    value_list = []    table = PrettyTable()    table._set_field_names('车次 出发地点 到达地点 出发时间 到达时间 历时 一等 二等 软卧 硬卧 硬座 无座'.split())    for key,value in stations.items():        key_list.append(key)        value_list.append(value)    for raw_train in Get_train_text():        data_list = raw_train.split('|')        train_number = data_list[3]  #车次        from_station_code = data_list[6]  #始发站信息        to_station_code = data_list[7] #终点站信息        from_station_index = value_list.index(from_station_code)        to_station_index = value_list.index(to_station_code)        from_station_name = key_list[from_station_index]        to_station_name = key_list[to_station_index]         start_time = data_list[8] #出发时间        arrive_time = data_list[9]  #到达时间        time_duration = data_list[10]  #历时        first_class_seat = data_list[31] #一等座        second_class_seat = data_list[30] #二等座        soft_sleeper = data_list[23] or '--' #软卧        hard_sleeper = data_list[28] or '--'  #硬卧        hard_seat= data_list[29] or '--' #硬座        no_seat = data_list[26] or '--'  #无座        table.add_row([            train_number,            from_station_name,             to_station_name,            start_time,             arrive_time,            time_duration,            first_class_seat,            second_class_seat,            soft_sleeper,            hard_sleeper,            hard_seat,            no_seat                  ])    print tableif __name__ == '__main__':    Get_train_information()

0x02 Selenium模块简单介绍

之后的，咱们应该都要用Python中selenium模块，怎么说呢，这个东西，我感觉挺好用的唉
这里呢，我简单的说下
安装
pip install selenium
安装Firefox
http://ftp.mozilla.org/pub/firefox/releases/
安装FirefoxDriver，geckdriver
https://github.com/mozilla/geckodriver/releases
Chrome浏览器需要安装chromedriver，IE浏览器要安装IEdriver
driver的路径可以直接放在python路径下，我这里把driver放在了python的Scripts路径下，同时把script路径加入环境变量。
说几个简单用法..
访问页面并获取源码

#-*- coding: UTF-8 -*-from selenium import webdriver browser = webdriver.Firefox()browser.get("http://www.baidu.com")print browser.page_source browser.close()

浏览器最大化

driver.maximize_window()

设置浏览器大小

driver.set_window_size(480, 800)

浏览器前进后退

driver.back()#浏览器后退driver.forward()#浏览器前进

webdriver 提供了一系列的元素定位方法，常用的有以下几种：

id
name
class name
tag name
link text
partial link text
xpath
css selector
分别对应python webdriver 中的方法为：

find_element_by_id()
find_element_by_name()
find_element_by_class_name()
find_element_by_tag_name()
find_element_by_link_text()
find_element_by_partial_link_text()
find_element_by_xpath()
find_element_by_css_selector()

就简单介绍到这，写的很不详细吧....
这里呢？你可以去看官方文档
http://selenium-python.readthedocs.io/index.html

0x03 打造属于自己的SupremeBOT

Supreme1994年秋季诞生于美国纽约曼哈顿，由James Jebbia创办。supreme的本意是最高、至上的。Supreme是结合滑板、Hip-hop等文化并以滑板为主的美国街头服饰品牌。

那什么，我要说一下，是supreme[su:ˈpri:m]（苏普瑞姆)，而不是super me
找人代购又太贵，价格炒的高的不要不要得，还有一堆BOT。。。。所以呢，我就有了个打造属于自己得SUPREMEBOT了，啊哈哈

在这里强调一下，人生苦短，我用Python

还是采用分步写，不看别的，只看思路，对对对
官网地址：http://www.supremenewyork.com/
首先，咱们先判断，商品是不是存在，并加入购物车，我拿supreme的配件做的演示，没有加判断SIZE的。。。我后面会贴上，很简单的，几行代码的事情，啊哈哈我定义了三个函数，第一个函数，是遍历商品关键字的，第二个函数是，判断商品是否存在的，第三个是main函数(主要是为了装X吧，啊哈哈)

我直接贴代码了。。

#-*- coding: UTF-8 -*-import timetry:      from selenium import webdriverexcept ImportError:    print "Selenium module is not installed...Exiting program."    exit(1)     def Check(keywords, text):    for i in keywords:        if i not in text:            return False    return True def searchCommodity(browser, category, keywords, color):        print " Searching Commodity ..."    browser.get("http://www.supremenewyork.com/shop/all/" + category)    links = browser.find_elements_by_class_name("name-link")    i = 0    while i < len(links):        if (Check(keywords, links[i].text) & (color in links[i+1].text)):            links[i].click()            print "[/i][/i][i][i] Commodity found"            return True        i += 2    print "[/i][/i][i][i] Commodity not found"    return Falsedef main():    browser = webdriver.Firefox()    browser.implicitly_wait(5)  #隐性等待5s，隐形等待是设置了一个最长等待时间，如果在规定时间内网页加载完成，则执行下一步，否则一直等到时间截止，然后执行下一步    category = "accessories"  #商品类别    keywords = []    keywords.append("Gold Pendant")  #商品关键字    color = "Gold"  #颜色    if searchCommodity(browser, category, keywords, color) == False:        return -1    try:        browser.find_element_by_name("commit").click()    except:         print "[/i][/i][i][i] Commodity sold out"         return -1if __name__ == '__main__':    main()

额，这里加个商品描述吧，好看一点，啊哈哈

print "Description : " + links[i].textprint "Color : " + links[i+1].text

把商品加入了购物车了，就该买单了，是不是，啊哈哈，如果手动填，肯定会错过，所以selenium的功效来了

我又定义了函数fillForm，这里面的收货信息什么的都要改，改成你的信息

强调一下，我写的是美国官网，英国官网貌似在信息那多了个啥，忘了。。。。

差不多是这样，可以加个raw_input,这样就可以省去打开浏览器的时间了，对对对，最后放上完全版的，可以抢帽衫什么的
