在 python 中使用 selenium 填充用户名和密码

如何在以下连结自动填写使用者名称及密码:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys


chromedriver = 'C:\\chromedriver.exe'
browser = webdriver.Chrome(chromedriver)
browser.get('http://www.example.com')

之后我真的不知道:

username = Select(browser.find_element_by_name('Username'))
password = Select(browser.find_element_by_name('Password'))
username.select_by_visible_text("text")
password.select_by_visible_text("text")

For versions 4.3.0 (released in June 2022) and later, calls to find_element_by_* and find_elements_by_* were removed from Selenium. You need to use the new API:

from selenium.webdriver.common.by import By


driver = webdriver.Firefox(...)  # Or Chrome(), or Ie(), or Opera()


# To catch <input type="text" id="passwd" />
password = driver.find_element(By.ID, "passwd")
# To catch <input type="text" name="passwd" />
password = driver.find_element(By.NAME, "passwd")


password.send_keys("Pa55worD")


driver.find_element(By.NAME, "submit").click()

The original response, for API versions 4.2.0 or previous:

driver = webdriver.Firefox(...)  # Or Chrome(), or Ie(), or Opera()


username = driver.find_element_by_id("username")
password = driver.find_element_by_id("password")


username.send_keys("YourUsername")
password.send_keys("Pa55worD")


driver.find_element_by_name("submit").click()

A note to your code: Select() is used to act on a Select Element (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select).

Use WebElement.send_keys method to simulate key typing.

name in the code (Username, Password) does not match actual name of the elements (username, password).

username = browser.find_element_by_name('username')
username.send_keys('user1')


password = browser.find_element_by_name('password')
password.send_keys('secret')


form = browser.find_element_by_id('loginForm')
form.submit()


# OR  browser.find_element_by_id('submit').click()

user = driver.find_element_by_name("username")
password = driver.find_element_by_name("password")
user.clear()
user.send_keys("your_user_name")
password.clear()
password.send_keys("your_password")
driver.find_element_by_name("submit").click()

Note:

  • we useuser.clear() in order to clear the input field.
  • for locating submit button you can use any other method based on the page source code. for info see locating elements

In some cases when the element is not interactable, sendKeys() doesn't work and you're likely to encounter an ElementNotInteractableException.

In such cases, you can opt to execute javascript that sets the values and then can post back.

Example:

url = 'https://www.your_url.com/'


driver = Chrome(executable_path="./chromedriver")
driver.get(url)


username = 'your_username'
password = 'your_password'


#Setting the value of email input field
driver.execute_script(f'var element = document.getElementById("email"); element.value = "{username}";')


#Setting the value of password input field
driver.execute_script(f'var element = document.getElementById("password"); element.value = "{password}";')


#Submitting the form or click the login button also
driver.execute_script(f'document.getElementsByClassName("login_form")[0].submit();')


print(driver.page_source)

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.webdriver.support.ui import WebDriverWait


# If you want to open Chrome
driver = webdriver.Chrome()
# If you want to open Firefox
driver = webdriver.Firefox()


username = driver.find_element_by_id("username")
password = driver.find_element_by_id("password")
username.send_keys("YourUsername")
password.send_keys("YourPassword")
driver.find_element_by_id("submit_btn").click()

I am new to selenium and I tried all solutions above but they don't work. Finally, I tried this manually by

driver = webdriver.Firefox()
import time


driver.get(url)


time.sleep(20)


print (driver.page_source.encode("utf-8"))

Then I could get contents from web.

Here is the complete answer.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By


chrome_driver_path = 'C:\\chromedriver.exe'
browser = webdriver.Chrome(service=Service(chrome_driver_path))
browser.get('http://www.example.com')


username = browser.find_element(By.NAME, 'Username')
password = browser.find_element(By.NAME, 'Password')


username.send_keys("yourUsername") #type your own username here
password.send_keys("yourPassword") #type your own password here


browser.find_element(By.NAME, 'submit').click()

Since find_element_by_name() is deprecated, you can use find_element(By.NAME, 'name').

Also you have to import from selenium.webdriver.common.by import By
