我正在编写用于使用凭据自动执行登录操作的脚本。我遵循通过名称，类，xpath查找元素的标准过程。输入字段未获取凭据。我尝试在每个进程之间给出10秒的时间间隔，但问题仍然存在。
下面我已经证明了代码。
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.select import Select
from selenium.webdriver.common.keys import Keys
import time
driver = webdriver.Firefox()
driver.get() #WEBSITE HERE
time.sleep(10)
elem = driver.find_element_by_xpath('//*[@id="ssousernameUI"]')
elem.clear()
elem.send_keys() # USERNAME HERE
elem.send_keys(Keys.RETURN)
time.sleep(10)
passwd = driver.find_element_by_xpath('//*[@id="password"]')
passwd.clear()
passwd.send_keys() #PASSWORD HERE
passwd.send_keys(Keys.RETURN)
time.sleep(10)
login = driver.find_element_by_link_text("Login")
login.click()
错误消息：

答案 0 :(得分：1)
NoSuchElementException是因为webdriver无法在网页中找到该元素。检查网页中是否有任何框架。切换到它，如果有的话。
答案 1 :(得分：0)
您需要单击元素以使该元素聚焦，然后输入用户名/密码详细信息。 如果这也不起作用，请尝试使用显式等待包装find元素语句。 如果有帮助，请告诉我。
EDIT1：
elem.click();
elem.send_keys();
time.sleep(50);
EDIT2： 而不是：
elem = driver.find_element_by_xpath('//*[@id="ssousernameUI"]')
你可以尝试：
driver.find_element_by_xpath('//*[@id="ssousernameUI"]').click()
答案 2 :(得分：0)
第一眼看来，似乎你的xpath不正确。 而不是使用：
elem = driver.find_element_by_xpath（'// * [@ id =“ssousernameUI”]'）
试试这个：
elem = driver.find_element_by_xpath（“// * [@ id ='ssousernameUI']”）
答案 3 :(得分：0)
根据您分享的credentials来填充from selenium import webdriver
driver = webdriver.Firefox()
driver.get("your_website") #WEBSITE HERE
username = driver.find_element_by_xpath("//input[@id='ssousernameUI']").click()
username.clear()
username.send_keys("user_name") # USERNAME HERE
password = driver.find_element_by_xpath("//input[@id='password']").click()
password.clear()
password.send_keys("Pa$$w0rd") #PASSWORD HERE
driver.find_element_by_xpath("//a[@class='purpleBtn' and contains(.,'Login')]").click()
，您可以使用以下代码块：
append答案 4 :(得分：0)
谢谢。我解决了
该网站有多个登录页面，因此他们使用iframe来满足多个页面中的登录访问权限。
问题是，登录位于iframe内。我提到了切换框架的文档。 我用了
driver.switch_to_frame("frameName")
谢谢@Arun Prakash和大家。
