用代码怎么在京东上抢1499元的茅台

首先，需要使用Python来实现自动化抢购。

1. 导入必要的库和模块

import time
import selenium.webdriver as webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

2. 设置chrome浏览器并打开京东茅台的页面

options = webdriver.ChromeOptions()
options.add_argument('user-data-dir=C:\\Users\\{username}\\AppData\\Local\\Google\\Chrome\\User Data')  # 将{username}替换为你的计算机用户名
browser = webdriver.Chrome(chrome_options=options)
browser.get('https://item.jd.com/100012043978.html')

3. 等待页面加载并定位抢购按钮，点击抢购按钮

while True:
    try:
        timer = WebDriverWait(browser, 1).until(EC.presence_of_element_located((By.ID, 'btn-reservation')))
        if timer.text == '立即预约':
            timer.click()
        elif timer.text == '已成功预约':
            print('已成功预约')
            break
    except:
        pass

4. 等待预约成功页面加载，并定位到抢购按钮，点击抢购按钮

while True:
    try:
        btn = WebDriverWait(browser, 1).until(EC.presence_of_element_located((By.ID, 'btn-reservation-attention')))
        if btn.text == '提醒我':
            btn.click()
        elif btn.text == '已设置提醒':
            print('已设置提醒')
            break
    except:
        pass

5. 等待抢购页面加载，并定位到抢购按钮，点击抢购按钮

while True:
    try:
        btn = WebDriverWait(browser, 1).until(EC.presence_of_element_located((By.ID, 'btn-reservation-order')))
        if btn.text == '立即抢购':
            btn.click()
            break
        elif btn.text == '已添加到购物车':
            print('已添加到购物车')
            break
    except:
        pass

6. 等待购物车页面加载，并定位到提交订单按钮，点击提交订单按钮

while True:
    try:
        btn = WebDriverWait(browser, 1).until(EC.presence_of_element_located((By.CLASS_NAME, 'submit-btn')))
        if btn.text == '提交订单':
            btn.click()
            break
    except:
        pass

7. 等待订单确认页面加载，并勾选同意协议，提交订单

while True:
    try:
        input = WebDriverWait(browser, 1).until(EC.presence_of_element_located((By.ID, 'order-submit')))
        if input.get_attribute('class') == 'submit-btn order-submit J_orderSubmit':
            agree = WebDriverWait(browser, 1).until(EC.presence_of_element_located((By.CLASS_NAME, 'payment-bd-agree')))
            if not agree.is_selected():
                agree.click()
            input.click()
            break
    except:
        pass
