python - Selenium Python 3.4.3 登录 Gmail : Password section

Question

下面是我到目前为止的代码。它应该访问该网站并使用所有必要的详细信息登录，但我不断收到大量错误!我不明白错误隐藏在哪里，任何看到它的人请帮忙。谢谢!

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

browser = webdriver.Firefox()
from selenium.webdriver.common.keys import Keys
#browser.get('https://mail.yahoo.com')
browser.get('https://accounts.google.com/ServiceLogin?sacu=1&scc=1&continue=https%3A%2F%2Fmail.google.com%2Fmail%2F&hl=en&service=mail#identifier')

emailElem = browser.find_element_by_id('Email')
emailElem.send_keys('email_address')
nextButton = browser.find_element_by_id('next')
nextButton.click()
passwordElem = browser.find_element_by_id('Passwd')

wait = WebDriverWait(browser, 10)
passwordElem = wait.until(EC.visibility_of_element_located((By.ID, "Passwd")))
passwordElem.clear()
passwordElem.send_keys('12345')

SignIn = browser.find_element_by_id('signIn')
SignIn.click()

#passwordElem.clear()
#passwordElem.send_keys('12345')
#SignIn = browser.find_elements_by_id('signIn')
#SignIn.click()
#passwordElem.submit()

这是我收到的错误:

Answer 1

输入电子邮件并提交表单后，wait for the password field to be visible :

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

# wait for the password field to be visible
wait = WebDriverWait(browser, 10)
passwordElem = wait.until(EC.visibility_of_element_located((By.ID, "Passwd")))
passwordElem.clear()
passwordElem.send_keys('12345')

SignIn = browser.find_element_by_id('signIn')
SignIn.click()

另请注意，您必须使用 find_element_by_id() 而不是 find_elements_by_id() 方法来找到“登录”按钮。
