在python中使用硒填充用户名和密码

Question 1

如何通过以下链接自动填写用户名和密码：

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")

Question 2

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()

代码注释：

find_element_by_name('Username')：Username大写不匹配任何内容。
Select()用于对Select元素执行操作（https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select）

Question 3

使用WebElement.send_keys方法模拟键键入。

name在代码（Username，Password）不匹配实际name的元件（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()

Question 4

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()

注意：

我们user.clear()用来清除输入字段。
要查找“提交”按钮，可以使用基于页面源代码的任何其他方法。有关信息，请参见定位元素

Question 5

在某些情况下，该元素不可交互，将sendKeys()无法正常工作，并且您可能会遇到ElementNotInteractableException。

在这种情况下，您可以选择执行设置值的javascript，然后可以回发。

例：

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)

Question 6

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()
