python - 如何通过Selenium WebDriver和Python定位用户名和密码元素

我正在尝试使用 Selenium 自动输入特定网站的用户名和密码。我无法找到要将 key 发送到的元素。我在下面附上了该网站的 HTML 代码。

这是我目前使用的:

username = driver.find_element_by_id('UserName').getAttribute('value')

此外，该网站以 .bsd 结尾，我并不完全熟悉它，并认为它可能是导致问题的原因。

谢谢。

最佳答案

只需使用WebDriverWait:

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

driver = webdriver.Chrome(executable_path=r'C:\path\To\chromedriver.exe')
driver.get(url)

wait = WebDriverWait(driver, 10)

username = wait.until(EC.presence_of_element_located((By.XPATH, "//input[@id='UserName']")))

# username = driver.find_element_by_xpath("//input[@id='UserName']")
username.send_keys("the useName")

# password = driver.find_element_by_xpath("//input[@id='Password']")

password =wait.until(EC.presence_of_element_located((By.XPATH, "//input[@id='Password']")))
password.send_keys("yourPassword")
