问题
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:
Traceback (most recent call last):
File "C:\Users\Surojit\Desktop\Python\automaticpasswordFiller.py", line 21, in <module>
passwordElem = browser.find_element_by_id('Passwd')

The simple code that I have written is:
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()
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
Can someone please guide me on the right path and let me know where I am making a mistake?
P.S: This is my first post on stackoverflow. Please excuse me for any mistake that I have made in posting the question
回答1:
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()
recommended method is browser.implicitly_wait(num_of_seconds) see this

I hope that, it will be helpful for automate the gmail in updated chrome version.
from selenium import webdriver
import time
driver = webdriver.Chrome()
driver.get("http://gmail.com")
driver.find_element_by_id("identifierId").send_keys('your mail id')
driver.find_element_by_id("identifierNext").click()
time.sleep(5)
driver.find_element_by_name("password").send_keys('your password')
driver.find_element_by_id("passwordNext").click()
time.sleep(5)
driver.get("https://accounts.google.com/SignOutOptions?hl=en&continue=https://mail.google.com/mail&service=mail")
driver.find_element_by_xpath('//button[normalize-space()="Sign out"]').click()
driver.close()

In 2020 signing in with Gmail is much more tougher because Gmail takes selenium operated window as a bot window and will give a message like this one.img of error
But now I have found a successful way to log in without any error or warning by google.
you can log in to another website as google will accept it as secure login using another website like StackOverflow or some other website with Gmail login.
def gmail_sign_in(email, password):
driver = webdriver.Chrome()
driver.get('https://stackoverflow.com/users/signup?ssrc=head&returnurl=%2fusers%2fstory%2fcurrent')
driver.find_element_by_xpath('//*[@id="openid-buttons"]/button[1]').click()
driver.find_element_by_xpath('//*[@id="identifierId"]').send_keys(email)
input = WebDriverWait(driver, 10).until(
EC.element_to_be_clickable((By.XPATH, '//*[@id="identifierNext"]/span/span'))
)
input.click()
driver.implicitly_wait(1)
driver.find_element_by_xpath('//*[@id="password"]/div[1]/div/div[1]/input').send_keys(password)
input = WebDriverWait(driver, 10).until(
EC.element_to_be_clickable((By.XPATH, '//*[@id="passwordNext"]/span/span'))
)
input.click()
driver.implicitly_wait(1)
driver.get('https://www.google.com/')
hope the code is understandable just this function and put your email and password make sure you have the appropriate imports.
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

You can use key to avoid one more search for next element
from selenium.webdriver.common.keys import Keys
def login_gmail(email,password):
browser.find_element_by_name('Email').send_keys(email+Keys.ENTER)
time.sleep(2)
browser.find_element_by_name('Passwd').send_keys(password+Keys.ENTER)
回答5:
You can do this but I would not recommend automation something like gmail. It would not be a good practise. For testing emails - I would suggest a tool like - https://putsbox.com/
回答6:
The method shearching for ID is no longer working for me too .
I checked the docs and found out a bunch of other methods to get to success .
Try searching the element by NAME , it works.
password = wait.until(
EC.element_to_be_clickable((By.NAME,'password')))
CLASS_NAME

The problem is gmail changed the way login works. You insert your email on one page then click next and then you get a new page where you insert the password and click on sign in. Try something like this:
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://gmail.com')
emailElem = browser.find_element_by_id('Email')
emailElem.send_keys('MyUserName')
nextButton = browser.find_element_by_id('next')
nextButton.click()
passwordElem = browser.find_element_by_id('Passwd')
passwordElem.send_keys('MyPassword')
signinButton = browser.find_element_by_id('signIn')
signinButton.click()
回答8:
The best way is to use explicit waits when you need to wait any element. It's better than time.sleep(1).
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()
browser.get('http://gmail.com')
wait = WebDriverWait(browser, 10)
password_elem = wait.until(EC.presence_of_element_located((By.ID,'Passwd')))
password_elem.send_keys("MyPassword")
browser.find_element_by_name('signIn').click()
Hope, this will help you.

This is a more updated version
def loginToGmail():
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
from time import sleep
chrome_driver = "C:/Python37/chromedriver.exe"
browser = webdriver.Chrome(chrome_driver)
browser.get('https://gmail.com')
if "inbox" in browser.current_url:
print("Logged in")
else:
identifier=WebDriverWait(browser, 30).until(EC.presence_of_element_located((By.NAME, "identifier")))
identifier.send_keys(LOGIN)
nextBtn = browser.find_element_by_id ('identifierNext')
nextBtn.click()
sleep(1)
password=WebDriverWait(browser, 30).until(EC.presence_of_element_located((By.NAME, "password")))
password.send_keys(PASSWD)
nextBtn = browser.find_element_by_id('passwordNext')
nextBtn.click()
waitTimer=0
logged=False
while waitTimer<30 and not logged:
sleep(1)
waitTimer+=1
if "inbox" in browser.current_url:
logged=True
print("Logged in")
