我正在尝试自动登录网站，下面是我使用的代码。
from selenium import webdriver
chromedriver = "C:/Lujing/chromedriver.exe"
browser = webdriver.Chrome(chromedriver)
browser.get("https://community-pm.p.cloud.sabrehospitality.com/pms-web-ui/login")
browser.implicitly_wait(10)
userElem = browser.find_element_by_id("spark-input_1")
userElem.send_keys("input user name") #enter user name in the quote
passwordElem = browser.find_element_by_id("spark-input_2")
passwordElem.send_keys("input password") #enter password in the quote
signin = browser.find_element_by_class_name('login-button spark-btn spark-btn--md spark-btn--primary spark-block--lte-sm spark-margin-bottom--md spark-pull-right--gte-sm')
type(signin)
signin.click()
我也尝试过使用find_element_by_xpath("//*[@id='spark-input_1']")，但我一直收到下面的错误消息。

有人能帮我吗？
以下是输入username字段值的有效解决方案。您可以弄清楚如何处理密码字段和提交按钮。注意，我和壁虎司机有问题。我不确定它是否适用于你，但它适用于我的Chromedriver。
正如我在对您的帖子的评论中提到的，您找不到元素的原因是因为shadowDOM。您可以使用一些javascript来传递它。请注意，在网站的未来页面中，您可能会遇到一个嵌套的shadowDOM，它需要与下面类似的解决方案，但是递归的。
browser = webdriver.Chrome()
browser.get("https://community-pm.p.cloud.sabrehospitality.com/pms-web-ui/login")
shadow_root = browser.execute_script('return arguments[0].shadowRoot', browser.find_element_by_tag_name("sabre-shs-login"))
userElem = shadow_root.find_element_by_id('spark-input_1')
userElem.send_keys("input user name") #enter user name in the quote
