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

Question

我需要一些帮助。 有网址： https ://www.inipec.gov.it/cerca-pec/-/pecs/companies。 我需要单击复选框验证码：

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()

执行过程中出现错误：

driver.find_elements_by_xpath('//*[@id="recaptcha-anchor"]/div 1 ').click() AttributeError: 'list' object has no attribute 'click'

请帮忙解决。

Answer 1

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

• 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()

我解决了这个<\/strong>

from selenium import webdriver
from selenium.webdriver.support.select import Select
from selenium.common.exceptions import SessionNotCreatedException

options = webdriver.ChromeOptions()
prefs = {"download.default_directory": download_dir}
options.add_experimental_option("prefs", prefs)
options.add_argument("--no-sandbox")
    
driver = webdriver.Chrome("/usr/bin/chromedriver", chrome_options = options)
driver.get("url")

driver.maximize_window()
price = driver.find_element_by_xpath("//div[@class='g-recaptcha']")
price_content = price.get_attribute('innerHTML')
start = str(price_content).find(";k=")+len(";k=")
end = str(price_content).find("&co")
driver.implicitly_wait(20)
driver.execute_script("document.getElementById('g-recaptcha-response').style.display = '';")
recaptcha_text_area = driver.find_element_by_id("g-recaptcha-response")
    
recaptcha_text_area.clear()
recaptcha_text_area.send_keys(price_content[start:end])
    #.....................................................................................
    
button = driver.find_element_by_id("login_submit")
