在python中使用selenium填写用户名和密码

Question

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")

Answer 1

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()

您的代码注释:

• find_element_by_name('Username'):Username大写与任何东西都不匹配.
• Select()用于操作选择元素(https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select)

Answer 2

使用WebElement.send_keys方法来模拟键输入.

name在代码(Username,Password)中与name元素(username,password)的实际不匹配.

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()

Answer 3

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:

• 我们用user.clear()它来清除输入字段.
• 要查找提交按钮,您可以使用基于页面源代码的任何其他方法.有关信息,请参阅定位元素

Answer 4

在某些情况下，当元素不可交互、sendKeys()不起作用并且您可能会遇到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。

例子：

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)
