Selenium Python 3.4.3登錄到Gmail：密碼部分

Question

以下是我的代碼到目前爲止。它應該去的網站和登錄所有必要的細節，但我繼續得到大量的錯誤！我不明白錯誤隱藏在哪裏，任何看到它的人都請幫忙。謝謝！

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() 

這是我收到的錯誤：

    passwordElem = browser.find_element_by_id('Passwd')

Answer 1

後您輸入您的電子郵件並提交表單，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() 

另外請注意，您必須使用find_element_by_id()代替的find_elements_by_id()方法找到「登錄」按鈕。
