这是一个简单的网站 https://www.google.com/recaptcha/api2/demo 我想在验证码字段中找到上面的文字我尝试通过 id 到达它，但它没有打印文本我试图到达更大的元素，然后到达小的元素，但没有成功

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

PATH ="C:\Program Files (x86)/chromedriver.exe"
driver = webdriver.Chrome(PATH)

driver.get("https://www.google.com/recaptcha/api2/demo")
time.sleep(10)
try:
   nom = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.XPATH, '//*[@id="recaptcha-demo-form"]/fieldset/ul/li[1]/label'))   
    )
   print(nom.text)
   h = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "recaptcha-accessible-status"))   
    )
   
   print(h.text)
   
except:
    driver.close()

请帮忙

Answer 1

您提供的第一个片段只有文本，DOM 很小，只有 ID 会带您到元素。

captcha = driver.find_element(By.ID, "recaptcha-accessible-status")

DOM Snapshot

我点击了您在 link 中显示的网站，它显示给我的是英文。这里的 DOM 比第一个片段大。

driver.find_element(By.XPATH, "//form[@id='recaptcha-demo-form']//legend"] 这应该会带您到正文。

DOM Snapshot2

如果您尝试访问验证码复选框，则必须先切换到 iframe，然后再访问该元素，因为它位于 iframe 中。

frame = driver.find_element(By.XPATH, "//iframe[@title='reCAPTCHA'])
driver.switch_to.frame(frame)
#your code here
# to come back to parent window,use:
driver.swtich_to.default_content()

iframe DOM Snapshot
