Selenium 无法在网页中找到元素

Question

我在尝试自动化某些 Web 输入时遇到了一些麻烦，但首先我需要单击一些按钮，但我无法做到。 我尝试了很多东西，但我无法完成它:'(

网页： https : //vacunacovid.catsalut.gencat.cat/

我无法通过我拥有的代码的图像：

 rom selenium import webdriver from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.common.by import By import time # browser config options = webdriver.ChromeOptions() options.add_argument('--start-maximized') options.add_argument('--disable-extensions') driver_path= "/C:/chromedriver_linux64/chromedriver" # este es el driver del navegador https://chromedriver.chromium.org/ driver = webdriver.Chrome(driver_path,chrome_options=options) #starting screen in optimal position driver.set_window_position(2000,0) driver.maximize_window() time.sleep(1) #getting website driver.get("https://vacunacovid.catsalut.gencat.cat/") #go to the element if its clickable WebDriverWait(driver, 5)\\ .until(EC.element_to_be_clickable((By.XPATH, BLABLABLA)))\\ .click()

它没有找到任何抛出这个 #shadow (open) 的东西，我该怎么做？ https://i.stack.imgur.com/it2nQ.png

它在Shadow-dom #shadow-root (open) 下所以你没有确切地提到你想点击哪个按钮，所以我点击了第一个按钮Demana o modifica cita

#adding some wait for application to load properly
sleep(5)

您只需采用如下所示的期望元素的 JS 路径并返回该元素

按F12->元素选项卡->右键单击（在元素上）->复制JS路径

javascript = 'return document.querySelector("body > vaccinapp-app").shadowRoot.querySelector("#pages > vaccinapp-shell").shadowRoot.querySelector("#main-shell-content > appointment-shell").shadowRoot.querySelector("#appointment-shell-content > appointment-onboarding").shadowRoot.querySelector("#dismiss-btn").shadowRoot.querySelector("#button")'

通过使用execute_script将访问 shadow-root (open) 下的元素

element = driver.execute_script(javascript)
element.click()

代码

options = webdriver.ChromeOptions()
options.add_argument('--start-maximized')
options.add_argument('--disable-extensions')
driver_path= "/C:/chromedriver_linux64/chromedriver" 
driver = webdriver.Chrome(driver_path,chrome_options=options)

#starting screen in optimal position
driver.set_window_position(2000,0)
driver.maximize_window()
time.sleep(1)

#getting website
driver.get("https://vacunacovid.catsalut.gencat.cat/")
sleep(5)
javascript = 'return document.querySelector("body > vaccinapp-app").shadowRoot.querySelector("#pages > vaccinapp-shell").shadowRoot.querySelector("#main-shell-content > appointment-shell").shadowRoot.querySelector("#appointment-shell-content > appointment-onboarding").shadowRoot.querySelector("#dismiss-btn").shadowRoot.querySelector("#button")'
element = driver.execute_script(javascript)
element.click()
