使用Python-Selenium自动执行GMAIL登录 [英] Automating GMAIL login using Python-Selenium

问题描述

我正在尝试使用Python的Selenium软件包自动登录到GMail.但是，我无法完成任务并出现以下错误:

I am trying to automate logging into GMail using Selenium package of Python. However, I am not able to accomplish the task and get the following error:

我编写的简单代码是:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
import time

browser = webdriver.Firefox()
browser.get('http://gmail.com')
action = webdriver.ActionChains(browser)
emailElem = browser.find_element_by_id('Email')
emailElem.send_keys("MyUserName")
browser.find_element_by_name('signIn').click()
#browser.get('https://accounts.google.com/ServiceLogin?         service=mail&continue=https://mail.google.com/mail/#password')
passwordElem = browser.find_element_by_id('Passwd')
passwordElem.send_keys("MyPassword")
browser.find_element_by_name('signIn').click()

此外，我试图通过与以下类似问题的答案进行比较来找出代码中的错误:

Also, I have tried to find out the error in my code by comparing it to an answer given to a similar question here at: Auto connect on my Gmail account with Python Selenium

有人可以引导我走上正确的道路，让我知道我在哪里犯错吗?

Can someone please guide me on the right path and let me know where I am making a mistake?

推荐答案

您正在尝试查找尚未加载dom的元素的Passwd id.尝试添加一些延迟，以便页面可以加载.

You are trying to find the Passwd id of the element which is not loaded in dom yet. Try adding some delay so that the page could load.

emailElem = browser.find_element_by_id('Email')
emailElem.send_keys('MyUserName')
nextButton = browser.find_element_by_id('next')
nextButton.click()
time.sleep(1)
passwordElem = browser.find_element_by_id('Passwd')
passwordElem.send_keys('MyPassword')
signinButton = browser.find_element_by_id('signIn')
signinButton.click()

推荐的方法是browser.implicitly_wait(num_of_seconds)，请参见

recommended method is browser.implicitly_wait(num_of_seconds) see this
