QQ登录的ifame的id每次都变，怎么去获取登录态

先登录QQ首页登录

然后再跳转到测试页面，这时测试页面就有登录态了

# coding=utf-8

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome()

driver.get("http://www.qq.com")

driver.maximize_window()

#获取qq登录态

driver.find_element_by_xpath(".//*[@id='loginGrayLayout']").click()

#登录表单在页面的框架中，所以要切换到该框架

driver.switch_to_frame("login_frame")

driver.find_element_by_id("switcher_plogin").click()

driver.find_element_by_id("u").clear()

driver.find_element_by_id("u").send_keys("QQ帐号")

driver.find_element_by_id("p").clear()

driver.find_element_by_id("p").send_keys("QQ密码")

driver.find_element_by_id("login_button").click()

#切换到测试页面

driver.get("http://beta.card.automall.qq.com/web")

#获取当前窗口

sreach_windows = driver.current_window_handle

driver.find_element_by_xpath(".//*[@id='content']/div[2]/div[1]/ul/a[1]/li/h2").click()

#获取当前所有窗口

all_handles = driver.window_handles

#窗口切换

for handle in all_handles:

    if handle !=sreach_windows:

       driver.switch_to.window(handle)

       driver.find_element_by_xpath(".//*[@id='content']/div/div[1]/div[2]/ul/li[4]/div/div[1]/span").click()

       driver.find_element_by_xpath(".//*[@id='pick-store']/ul[1]/li/a").click()

       driver.find_element_by_xpath(".//*[@id='act_buy_btn']/div/a").click()
