我试图在https://www.textnow.com/login上找到登录页面的用户名路径。我尝试通过x_path，ID，名称，类查找它，但是我的机器人无法找到它。有没有人有我可以尝试的任何可能的解决方案？

源代码：

"SUDO FUNCTION: OPEN A NEW TAB FOR TEXT NOW AND LOG IN"
driver.implicitly_wait(3)
driver.execute_script("window.open('http://www.textnow.com/login','new window')")

textNowEmail = driver.find_element_by_id('txt-username')# still have not found username textfield 
textNowEmail.send_keys(textNowUser)

#Set password code 
textNowPass = driver.find_element_by_id('txt-password')
textNowPass.send_keys('fill')

这是即时消息：

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="txt-username"]"}
  (Session info: chrome=78.0.3904.108)

要将字符序列发送到网站https://www.textnow.com/login中的“电子邮件”或“用户名和密码”字段，您必须为引入WebDriverWait，并且可以使用以下定位策略之一：element_to_be_clickable()

使用CSS_SELECTOR：

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("https://www.textnow.com/login")
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.uikit-text-field__input#txt-username"))).send_keys("Xavier-Uriel-Espinal")
driver.find_element_by_css_selector("input.uikit-text-field__input#txt-password").send_keys("Xavier-Uriel-Espinal")

使用XPATH：

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("https://www.textnow.com/login")
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='uikit-text-field__input' and @id='txt-username']"))).send_keys("Xavier-Uriel-Espinal")
driver.find_element_by_xpath("//input[@class='uikit-text-field__input' and @id='txt-password']").send_keys("Xavier-Uriel-Espinal")

注意：您必须添加以下导入：

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