找到 reCAPTCHA 元素并点击它——Python + Selenium

Question

我需要帮助。有网址：https://www.inipec.gov.it/cerca-pec/-/pecs/companies。我需要点击复选框验证码：

我的代码看起来像：

import os, urllib.request, requests, datetime, time, random, ssl, json, codecs, csv, urllib
from urllib.request import Request, urlopen
from urllib.request import urlretrieve
from datetime import datetime
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import NoAlertPresentException
from selenium.webdriver.chrome.options import Options

chromedriver = "chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
chrome_options = webdriver.ChromeOptions()
driver = webdriver.Chrome(executable_path=chromedriver, chrome_options=chrome_options)
driver.get("https://www.inipec.gov.it/cerca-pec/-/pecs/companies")
driver.switch_to_default_content()
element = driver.find_elements_by_css_selector('iframe')[1]
driver.switch_to_frame(element)

driver.find_elements_by_xpath('//*[@id="recaptcha-anchor"]/div[1]').click()

在执行过程中，出现错误：

driver.find_elements_by_xpath('//*[@id="recaptcha-anchor"]/div 1 ').click() AttributeError: 'list' 对象没有属性 'click'

请帮助修复它。

解决方案更新（2020 年 2 月 11 日）

使用以下一组二进制文件：

• 硒 v3.141.0
• ChromeDriver v80.0
• 铬版本 80.0

您可以使用以下更新的代码块作为解决方案：

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

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get("https://www.inipec.gov.it/cerca-pec/-/pecs/companies")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[name^='a-'][src^='https://www.google.com/recaptcha/api2/anchor?']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//span[@id='recaptcha-anchor']"))).click()

原解决方案

在该URLhttps://www.inipec.gov.it/cerca-pec/-/pecs/companies要调用click()的验证码复选框您需要：

• Induce WebDriverWait等待所需的框架可用并切换到它。
• Induce WebDriverWait使所需元素可点击。

• 您可以使用以下解决方案：

  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
  from selenium.webdriver.chrome.options import Options
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe', chrome_options=options)
  driver.get("https://www.inipec.gov.it/cerca-pec/-/pecs/companies")
  WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[name^='a-'][src^='https://www.google.com/recaptcha/api2/anchor?']")))
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//span[@class='recaptcha-checkbox goog-inline-block recaptcha-checkbox-unchecked rc-anchor-checkbox']/div[@class='recaptcha-checkbox-checkmark']"))).click()
