当我在 Selenium 中运行此代码时，它只是坐在那里永远加载网页。有没有人能让这个代码工作并将我带到登录表单？

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;
from selenium.webdriver.chrome.options import Options;
from selenium.webdriver.support.ui import WebDriverWait;
from selenium.webdriver.support import expected_conditions as EC;
import time;



browser = webdriver.Chrome()
browser.get('https://www.costcobusinessdelivery.com')

WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a#header_sign_in"))).click()

在网页保持无响应大约 5 分钟后，我收到此错误：

TimeoutException                          Traceback (most recent call last)
<ipython-input-6-47279e187da7> in <module>
     11 
     12 browser = webdriver.Chrome()
---> 13 browser.get('https://www.costcobusinessdelivery.com')
     14 
     15 WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a#header_sign_in"))).click()

    332         """

    319         response = self.command_executor.execute(driver_command, params)
    320         if response:
--> 321             self.error_handler.check_response(response)
    322             response['value'] = self._unwrap_value(
    323                 response.get('value', None))

要在网站https://www.costcobusinessdelivery.com/中以“登录/注册click()”的文本链接，您必须诱导WebDriverWait并且您可以使用以下任一定位器策略：element_to_be_clickable()

  • 使用PARTIAL_LINK_TEXT：

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, "Sign In / Register"))).click()

  • 使用CSS_SELECTOR：

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a#header_sign_in"))).click()

  • 使用XPATH：

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@id='header_sign_in']"))).click()

  • 注意：您必须添加以下导入：

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

  • 浏览器快照：
