How do I get Selenium to login to the website Cost

问题:

Picture of the screen it stays on forever:

I am having trouble getting Selenium to login to Costco.com. It basically freezes at the login screen and won't proceed to the next screen.

from selenium import webdriver;
from selenium.webdriver.support.ui import Select;
from selenium.webdriver.common.keys import Keys;
from selenium.webdriver.common.by import By;
import time;

browser = webdriver.Chrome()
browser.get('https://www.costcobusinessdelivery.com/LogonForm?URL=%2f')

email = browser.find_element_by_css_selector('#logonId')
email.click()
email.send_keys('my_email')

password = browser.find_element_by_css_selector('#logonPassword_id')
password.click()
password.send_keys('my_password')

zipcode = browser.find_element_by_css_selector('#deliveryZipCode')
zipcode.click()
zipcode.send_keys('my_zipcode')


login = browser.find_element_by_css_selector('#sign_in_button')
login.click()

After a few minutes of Selenium sitting there it then pops out the traceback. I've tried using beautifulsoup4 to login and pass the data back to Selenium but I 'm not sure if this works. So I first have to navigate to the page I need in Selenium then parse the data with BS4.

If the ID is available please use the ID and try out below example.

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

usernameStr = 'putYourUsernameHere'
passwordStr = 'putYourPasswordHere'
zipStr ='putZipCode'

browser = webdriver.Chrome()
browser.get(('https://www.costcobusinessdelivery.com/LogonForm?URL=%2f'))



username = browser.find_element_by_id('logonId')
username.send_keys(usernameStr)

password= browser.find_element_by_id('logonPassword_id')
password.send_keys(passwordStr)

zip= browser.find_element_by_id('logonPassword_id')
zip.send_keys(zipStr)



signInButton = browser.find_element_by_id('sign_in_button')
signInButton.click()

To login in to Costco.com through the url https://www.costcobusinessdelivery.com/LogonForm?URL=%2f you need to to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies:

• css_selector:

  driver.get("https://www.costcobusinessdelivery.com/LogonForm?URL=%2f")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#logonId"))).send_keys("[e-mail]")
  driver.find_element_by_css_selector("input#logonPassword_id").send_keys("my_password")
  driver.find_element_by_css_selector("input#deliveryZipCode").send_keys("54321")
  driver.find_element_by_css_selector("input#sign_in_button").click()
  

• xpath:

  driver.get("https://www.costcobusinessdelivery.com/LogonForm?URL=%2f")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@id='logonId']"))).send_keys("[e-mail]")
  driver.find_element_by_xpath("//input[@id='logonPassword_id']").send_keys("my_password")
  driver.find_element_by_xpath("//input[@id='deliveryZipCode']").send_keys("54321")
  driver.find_element_by_xpath("//input[@id='sign_in_button']").click()
