我使用 python 的 Selenium seesion 无法单击按钮

Question

嘿，我是 selenium 的新手，我正在尝试搜索我的 linkedin 个人资料，让我进入该个人资料并允许我单击登录按钮，这是代码（其中一部分来自 chatgpt）

import selenium
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

# Initialize the Chrome driver
driver = webdriver.Chrome()

try:
    # Maximize the browser window
    driver.maximize_window()

    # Open Google
    driver.get("https://www.google.com/")
    print("Opened Google.")

    # Locate the search bar and search for"my name Linkedin"
    element = driver.find_element(By.NAME, "q")
    element.clear()
    element.send_keys("my name Linkedin")
    element.send_keys(Keys.RETURN)
    print("Searched for 'my name Linkedin'.")

    # Wait for the search results to appear and click the LinkedIn link
    linkedin_link = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.XPATH, "//a[contains(@href, 'linkedin.com')]"))
    )
    linkedin_link.click()
    print("Clicked on LinkedIn link.")

    # Wait for the LinkedIn page to load and click the sign-in button
    sign_in_button = WebDriverWait(driver, 10).until(
        EC.element_to_be_clickable((By.XPATH, "//a[contains(@class, 'sign-in-modal__outlet-btn cursor-pointer btn-md btn-primary')]"))
    )
    sign_in_button.click()
    print("Clicked on 'Sign in' button.")

    # Verify the sign-in button is clicked by checking for the sign-in page elements
    WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "username"))
    )
    print("Sign-in page loaded successfully.")

except Exception as e:
    print("An error occurred:", e)
finally:
    # Wait for a while to see the result before quitting
    time.sleep(40)
    driver.quit()

我尝试的另一种方法非常基本，但效果不佳（我根据我的理解写的）

import selenium
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome()
driver.get("https://www.google.com/")
# to locate any element by its class name on the webpage
element = driver.find_element(By.CLASS_NAME,"gLFyf")
# to clear ant already present text
element.clear() 
#search for something on the search bar of the google webpage
element.send_keys("my name Linkedin")
element.send_keys(Keys.RETURN)
element = driver.find_element(By.CLASS_NAME,"VuuXrf")
element.click()
element = driver.find_element(By.CLASS_NAME,"sign-in-modal__outlet-btn cursor-pointer btn-md btn-primary")
element.click()
# element                           
time.sleep(40)
driver.quit()

谁能告诉我代码中的错误吗？

我试图让 selenium 会话单击 linkedin 上的登录按钮，但它不会这样做

Answer 1

检查下面的工作代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome()
driver.implicitly_wait(10)
driver.maximize_window()
driver.get("https://www.google.com/")
# Click on Accept all cookies
driver.find_element(By.XPATH, "//div[text()='Accept all']").click()
el = driver.find_element(By.CLASS_NAME,"gLFyf")
el.send_keys("my name Linkedin")
el.send_keys(Keys.RETURN)
driver.find_element(By.CLASS_NAME,"VuuXrf").click()
driver.find_element(By.XPATH,"//a[text()='Sign in']").click()
time.sleep(15)
driver.quit()

代码中的问题：

• 一旦您通过 selenium 启动 google，它就会在干净的浏览器配置文件中打开（类似于隐身模式）。您会注意到出现一个 cookie 弹出窗口。在继续采取进一步行动之前，您需要摆脱它。

• 以下代码不正确。当有多个类时，您不能使用

  CLASS_NAME

  定位器策略。

  element = driver.find_element(By.CLASS_NAME,"sign-in-modal__outlet-btn cursor-pointer btn-md btn-primary")
  

建议：

• 使用selenium的waits来有效地定位元素。您可以使用

  implicit

  或

  explicit

  等待。我最喜欢的等待是

  explicit waits

  。我在答案中使用了

  implicit wait

  。

• 您不必始终将元素存储在变量中。仅当您想在以下代码中多次使用它时，才将其存储在变量中。例如，更改以下代码，

  element = driver.find_element(By.CLASS_NAME,"VuuXrf")
  element.click()
  

  到，

  driver.find_element(By.CLASS_NAME,"VuuXrf").click()
