找到 reCAPTCHA 元素並點擊它——Python + Selenium

Question

我需要一些幫助。 有網址： https ://www.inipec.gov.it/cerca-pec/-/pecs/companies。 我需要單擊復選框驗證碼：

我的代碼看起來像：

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()

執行過程中出現錯誤：

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

請幫忙解決。

解決方案更新（2020 年 2 月 11 日）

使用以下一組二進制文件：

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

您可以使用以下更新的代碼塊作為解決方案：

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()

---

原解決方案

在 URL https://www.inipec.gov.it/cerca-pec/-/pecs/companies ，您需要在reCAPTCHA復選框上調用click() ：

• Induce WebDriverWait等待所需的框架可用並切換到它。
• Induce WebDriverWait使所需元素可點擊。

• 您可以使用以下解決方案：

   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()

我解決了這個<\/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")
