实例

#Python3.5

#coding:utf-8

#import scrapy

from selenium import webdriver

import time

import datetime

driver = webdriver.Firefox()

driver.get('https:www.jd.com/')

class JDLOGIN(object):

  def login_jd(self,num,pwd):

    driver.find_element_by_link_text('你好,请登录').click()

    time.sleep(10)

    driver.find_element_by_link_text('账户登录').click()

    time.sleep(3)

    driver.find_element_by_id('loginname').send_keys(num)

    driver.find_element_by_id('nloginpwd').send_keys(pwd)

    time.sleep(3)

    driver.find_element_by_id('loginsubmit').click()

    time.sleep(5)

    nowwhandle = driver.current_window_handle

    driver.find_element_by_link_text('我的购物车').click()

    allhandles = driver.window_handles

    for handle in allhandles:

      if handle != nowwhandle:

        driver.switch_to_window(handle)#切换至窗口 购物车页面

    time.sleep(5)

    driver.find_element_by_link_text('去结算').click()

    time.sleep(4)

  def buy_on_time(self,buytime):

    while True:

      now = datetime.datetime.now()

      if now.strftime('%Y-%m-%d %H:%M:%S') == buytime:

        driver.find_element_by_id('order-submit').click()

        time.sleep(3)

        print(now.strftime('%Y-%m-%d %H:%M:%S'))

        print('successful!!!')

      time.sleep(0.5)

      # 返回原先到的窗口

      #driver.switch_to_window(nowwhandle)

  def start(self,num,pwd,buytime):

    self.login_jd(num,pwd)

    self.buy_on_time(buytime)

jdlogin=JDLOGIN()

jdlogin.start('手机号','密码','秒杀时间' )

需要先将秒杀物品添加至购物车(必须为秒杀物品,秒杀无品加入购物车后结算时不需要勾选【全选框】),并提前设置默认收货地址。该代码为闲时所写,没有进一步优化,面向对象的函数也不够精简,不过功能已经实现需要在cmd命令行安装selenium包:pipinstallselenium。

上面就是实现京东秒杀功能代码了,现在那些神秘感变得没有那么强烈了吧,代码就这么多,感兴趣的记得在自己的环境试试,做一个简单的页面,看能不能实现秒杀功能,***,小猿圈加加给你们满满的干货,喜欢的话点个赞吧。
