python - Selenium WebDriver 等待不适用于 cookie 策略窗口的预期条件

问题描述

我试图摆脱 selenium 中的 cookie 策略窗口，该窗口弹出在我试图访问的网页的最前面。即使使用 . 尝试关闭它也是不可能的Expected conditions。我已经尝试过element_to_be_clickableand presence_of_element_located，但它们都不起作用。

奇怪的是，当我在 10 秒后执行关闭窗口的命令时，它起作用了。但是为什么WebDriver wait在这种情况下命令不起作用？另一个奇怪的事情是，当 selenium 选项卡打开时，我没有得到这个 cookie 策略窗口，只有当它减少时。

最后，根据我所阅读presence_of_element_located的内容，在网页中查找元素的“最长”预期条件。所以我在这一点上很受阻。

我得到的错误是：

所以我的问题是：1）为什么我只有在选项卡打开时才能获得这个 cookie 策略窗口 2）为什么预期的条件和等待语句不起作用 3）（最终）我怎样才能让我的代码正常工作？

任何帮助将不胜感激。非常感谢你

我的代码如下：

driver.get("https://www.marketwatch.com/watchlist")

WebDriverWait(driver, 60).until(EC.element_to_be_clickable((By.CLASS_NAME, "gdpr-close")))
driver.find_element_by_class_name('gdpr-close').click()

WebDriverWait(driver, 60).until(EC.element_to_be_clickable((By.ID, "wl-scrim-start")))
driver.find_element_by_id('wl-scrim-start').click()

WebDriverWait(driver, 60).until(EC.element_to_be_clickable((By.CLASS_NAME, "gdpr-close")))
driver.find_element_by_class_name('gdpr-close').click()

WebDriverWait(driver, 60).until(EC.presence_of_element_located((By.ID, "profilelogin")))
driver.find_element_by_id('profilelogin').click()

和：

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

解决方案

您正在等待 cookie 策略关闭按钮两次。您的代码第一次关闭 cookie 策略面板，因此它会一直等待按钮再次可点击，但在您关闭它后将无法点击。这就是为什么你得到例外。

尝试以下操作：

driver.get("https://www.marketwatch.com/watchlist")

wait = WebDriverWait(driver,30)

wait.until(EC.element_to_be_clickable((By.CLASS_NAME,"gdpr-close"))).click()

wait.until(EC.element_to_be_clickable((By.ID, "wl-scrim-start"))).click()

wait.until(EC.presence_of_element_located((By.ID, "profilelogin"))).click()

它会毫无例外地带您进入登录页面。
