如何使用selenium WebDriver自动化salesforce登录动态口令功能？

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

# 创建WebDriver实例
driver = webdriver.Chrome()

# 打开salesforce登录页面
driver.get("https://login.salesforce.com/")

# 输入用户名和密码
username = driver.find_element_by_id("username")
password = driver.find_element_by_id("password")
username.send_keys("your_username")
password.send_keys("your_password")

# 点击登录按钮
login_button = driver.find_element_by_id("Login")
login_button.click()

# 等待动态口令输入框出现
dynamic_password_input = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, "dynamic_password_input"))
)

# 输入动态口令
dynamic_password = driver.find_element_by_id("dynamic_password")
dynamic_password.send_keys("your_dynamic_password")

# 点击确认按钮
confirm_button = driver.find_element_by_id("confirm")
confirm_button.click()

# 登录成功后的操作
# ...

# 关闭浏览器
driver.quit()
