Initial load

from selenium import webdriver  # 操作浏览器的工具

def __init__(self):
    self.status = 0   # 状态, 表示当前操作执行到了哪个步骤
    self.login_method = 1  # {0:模拟登录, 1:cookie登录}自行选择登录的方式
    self.driver = webdriver.Chrome(executable_path='chromedriver.exe')  # 当前浏览器驱动对象

Log in

def login(self):
    if self.login_method == 0:
        self.driver.get(login_url)
        print('###开始登录###')
    elif self.login_method == 1:
        # 创建文件夹, 文件是否存在
        if not os.path.exists('cookies.pkl'):
            self.set_cookies()             # 没有文件的情况下, 登录一下
        else:
            self.driver.get(target_url)  # 跳转到抢票页
            self.get_cookie()           # 并且登录

cookies: Appears when logging into the website

import time       

def set_cookies(self):
    self.driver.get(damai_url)
    print('###请点击登录###')
    # 我没有点击登录,就会一直延时在首页, 不会进行跳转
    while self.driver.title.find('大麦网-全球演出赛事官方购票平台') != -1:
        sleep(1)
    print('###请扫码登录###')
    # 没有登录成功
    while self.driver.title != '大麦网-全球演出赛事官方购票平台-100%正品、先付先抢、在线选座！':
        sleep(1)
    print('###扫码成功###')
    # get_cookies: driver里面的方法
    pickle.dump(self.driver.get_cookies(), open('cookies.pkl', 'wb'))
    print('###cookie保存成功###')
    self.driver.get(target_url)

Suppose I have cookies locally.[pkl]

def get_cookie(self):
    cookies = pickle.load(open('cookies.pkl', 'rb'))
    for cookie in cookies:
        cookie_dict = {
    
    
            'domain': '.damai.cn',  # 必须要有的, 否则就是假登录
            'name': cookie.get('name'),
            'value': cookie.get('value')
        }
        self.driver.add_cookie(cookie_dict)
    print('###载入cookie###')

Running the code can get the required cookies, so that no login is required.

Open browser

def enter_concert(self):
    print('###打开浏览器,进入大麦网###')
    # 调用登录
    self.login()                # 先登录再说
    self.driver.refresh()       # 刷新页面
    self.status = 2             # 登录成功标识
    print('###登录成功###')
    # 处理弹窗
    if self.isElementExist('/html/body/div[2]/div[2]/div/div/div[3]/div[2]'):
        self.driver.find_element_by_xpath('/html/body/div[2]/div[2]/div/div/div[3]/div[2]').click()

                        self.check_order()

Select your seat

def choice_seats(self):

            self.driver.find_element_by_xpath('//*[@id="app"]/div[2]/div[2]/div[2]/button').click()

Order operation

def check_order(self):
    if self.status in [3, 4, 5]:
        print('###开始确认订单###')
        try:
            # 默认选第一个购票人信息

        # 最后一步提交订单
        time.sleep(0.5)  # 太快了不好, 影响加载 导致按钮点击无效
        self.driver.find_element_by_xpath('//*[@id="container"]/div/div[9]/button').click()

Determine whether the element exists

def isElementExist(self, element):
    flag = True
    browser = self.driver

        browser.find_element_by_xpath(element)
        return flag

        flag = False
        return flag

Ticket purchase completed, exit

def finish(self):
    self.driver.quit()
