找到reCAPTCHA元素并单击它— Python + Selenium

Question

我需要一些帮助。有URL：https : //www.inipec.gov.it/cercapec/-/pecs/companies。我需要单击复选框验证码：在此处输入图片说明

我的代码如下所示：

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()

During the execution, there is an error:

driver.find_elements_by_xpath(‘//*[@id=”recaptcha-
anchor”]/div1’).click()
AttributeError: ‘list’ object has no attribute ‘click’

Please, help to fix it.

Solution update (11-Feb-2020)

使用以下二进制文件集：

• Selenium v3.141.0
• ChromeDriver v80.0
• Chrome Version 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()

Original solution

在https://www.inipec.gov.it/cerca-pec/-/pecs/companies要在reCAPTCHA复选框上
调用的URL中，您需要：click()

诱导WebDriverWait获得所需的帧并切换到该帧。
诱导WebDriverWait使所需的元素可单击。
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()
