如何使用WebDriver选择合适的i框架

Question

给大家。 我有下一个网址：“ https://www.inipec.gov.it/cerca-pec/-/pecs/companies” 我需要通过网络驱动程序单击验证码上的音频按钮图标。 我可以单击验证码框，但无法访问音频按钮。 这是我的代码：

import os, urllib.request, requests, datetime, time, random, ssl, json, codecs, csv, urllib
import os.path
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
from bs4 import BeautifulSoup
from PIL import Image


proxy = "94.79.52.207:8080" # IP:PORT or HOST:PORT
chromedriver = "chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
options.add_argument('--proxy-server=%s' % proxy)
os.environ["webdriver.chrome.driver"] = chromedriver
chrome_options = webdriver.ChromeOptions()
driver = webdriver.Chrome(executable_path=chromedriver,       chrome_options=chrome_options)
driver.set_window_size(1050, 740)
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()

driver.switch_to.default_content()
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"#rc-imageselect > div.rc-footer > div.rc-controls > div.primary-controls")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, '//*[@id="recaptcha-audio-button"]'))).click()

Answer 1

只需将iFrame更改为XPath，就像这样：

WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,'//iframe[@title="recaptcha challenge"]')))

希望这对您有帮助！
