Gmail 中的错误通过谷歌搜索通过 Chromedriver 使用 Selenium Python 自动登录

Question

我是 RPA 新手，试图通过使用 Python Selenium-

我的代码-

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

#Code for lauching google chrome browser
chrome_options = webdriver.ChromeOptions()
#chrome_options.add_argument('- headless')
#chrome_options.add_argument('- no-sandbox')
#chrome_options.add_argument('- disable-dev-shm-usage')

driver = webdriver.Chrome("F:\\RPA\\Using Python\\chromedriver.exe", chrome_options = chrome_options)

driver.get("https://WWW.google.com/")
#print(driver.page_source)

xpathsearch = "//*[@id='tsf']/div[2]/div[1]/div[1]/div/div[2]/input"
searchinput = driver.find_element_by_xpath(xpathsearch)

searchinput.send_keys("Gmail")
searchinput.send_keys(Keys.ENTER)


xpathresult = "//*[@id='rso']/div[1]/div/div[1]/a/h3"
driver.find_element_by_xpath(xpathresult).click()

xpathresult = "/html/body/div[2]/div[1]/div[4]/ul[1]/li[2]/a"
driver.find_element_by_xpath(xpathresult).click(  )

xpathresult = "//*[@id='identifierId']"
driver.find_element_by_xpath(xpathresult).send_keys("somename2651996@gmail.com")

但在最后一行，它得到了一个错误 -

NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"xpathresult"}
  (Session info: chrome=83.0.4103.116)

为什么显示此错误？

注意-我正在使用 chrome 驱动器 83.0.4103.39 完整错误的图片-

你能帮我解决这个错误吗？我没有通过谷歌搜索得到任何帮助。 提前致谢。

我有另一种解决方案，可以毫不费力地工作。 在未检测到的浏览器 v2中使用Seleniumwire

from seleniumwire.undetected_chromedriver.v2 import Chrome, ChromeOptions
import time

options = {}
chrome_options = ChromeOptions()
chrome_options.add_argument('--user-data-dir=hash')
chrome_options.add_argument("--disable-gpu")
chrome_options.add_argument("--incognito")
chrome_options.add_argument("--disable-dev-shm-usage")
# chrome_options.add_argument("--headless")
browser = Chrome(seleniumwire_options=options, options=chrome_options)

browser.get('https://gmail.com')
browser.find_element_by_xpath('//*[@id="identifierId"]').send_keys('your-email')
browser.find_element_by_xpath('//*[@id="identifierNext"]/div/button').click()
time.sleep(5)
browser.find_element_by_xpath('//*[@id="password"]/div[1]/div/div[1]/input').send_keys('you-password')
browser.find_element_by_xpath('//*[@id="passwordNext"]/div/button').click()

除此之外，selenium 线还有许多很棒的功能，请查看 Github存储库

显示错误是因为帐户登录页面无法从上一页获取句柄，因此无法检测当前页面上的 Xpath，这就是显示错误的原因。

解决方案-

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

#Code for lauching google chrome browser
chrome_options = webdriver.ChromeOptions()
#chrome_options.add_argument('- headless')
#chrome_options.add_argument('- no-sandbox')
#chrome_options.add_argument('- disable-dev-shm-usage')

driver = webdriver.Chrome("F:\\RPA\\Using Python\\chromedriver.exe", chrome_options = chrome_options)

driver.get("https://WWW.google.com/")
#print(driver.page_source)

xpathsearch = "//*[@id='tsf']/div[2]/div[1]/div[1]/div/div[2]/input"
searchinput = driver.find_element_by_xpath(xpathsearch)

searchinput.send_keys("Gmail")
searchinput.send_keys(Keys.ENTER)


xpathresult = "//*[@id='rso']/div[1]/div/div[1]/a/h3"
driver.find_element_by_xpath(xpathresult).click()

xpathresult = "/html/body/div[2]/div[1]/div[4]/ul[1]/li[2]/a"
driver.find_element_by_xpath(xpathresult).click()

pre_login=driver.current_window_handle

for handle in driver.window_handles:
    if not(handle==pre_login):
        print(handle)
        login_page = handle
        break
        
driver.switch_to_window(login_page)
        

driver.find_element_by_class_name("Aa1VU")

xpathresult = '//*[@id="identifierId"]'
driver.find_element_by_xpath(xpathresult).send_keys("somemailid@gmail.com")
driver.find_element_by_xpath('//*[@id="identifierNext"]/div/button/div[2]').click()
