selenium.common.exceptions.NoSuchElementException 在 python 3.7 中使用硒

Question

我正在尝试使用 selenium 自动执行从打开特定网站到登录以搜索特定文章的过程。我可以执行的步骤很少，但在 'sign in' 步骤中遇到错误。

from selenium import webdriver
from selenium.webdriver.common.by import By
base = 'https://www.wsj.com'
url = 'https://www.wsj.com/search/term.html?KEYWORDS=cybersecurity&min-date=2018/04/01&max-date=2019/03/31&isAdvanced=true&daysback=90d&andor=AND&sort=date-desc&source=wsjarticle,wsjpro&page=1'

browser = webdriver.Safari(executable_path='/usr/bin/safaridriver')
browser.get(url)
browser.find_element_by_id('editions-select').click()
browser.find_element_by_id('na,us').click()
browser.find_element(By.XPATH,"//button[@type='button' and contains(.,'Sign In')]").click()
browser.find_element_by_id('username').send_keys('**#&^&@$@#$')
browser.find_element_by_id('password').send_keys('@#@$%%**')
browser.find_element_by_id('basic-login').click()
browser.find_element_by_id('masthead-container').click()
browser.find_element_by_id('searchInput').send_keys('cybersecurity')
browser.find_element_by_name('ADVANCED SEARCH').click()
browser.find_element_by_id('dp1560924131783').send_keys('2018/04/01')
browser.find_element_by_id('dp1560924131784').send_keys('2019/03/31')
browser.find_element_by_id('wsjblogs').click()
browser.find_element_by_id('wsjvideo').click()
browser.find_element_by_id('interactivemedia').click()
browser.find_element_by_id('sitesearch').click()

代码一直运行到这一行：

browser.find_element_by_id('na,us').click()

但在那之后它在这一行显示错误：

browser.find_element(By.XPATH,"//button[@type='button' and contains(.,'Sign In')]").click()

错误消息说：

selenium.common.exceptions.NoSuchElementException

我应该怎么做才能让它发挥作用？有什么问题？

Answer 1

你应该使用 WebDriverWait:

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

botton_to_click = WebDriverWait(driver, 10).until(EC.element_to_be_clickable, ((By.XPATH,"//button[@type='button' and contains(.,'Sign In')]")))
botton_to_click.click()

希望对您有所帮助！
