Selenium -使用python从html获取音频src

Question

我正在尝试使用selenium从recaptcha音频源获取特定的属性。

然而，我不知道如何做到这一点。下面是来自https://www.google.com/recaptcha/api2/demo的一个示例

1. 点击“我不是机器人”

1. 选择耳机

1. 提取src链接

我想检索src链接并打印出来。

我想知道是否有什么方法可以让我使用selenium来做到这一点？

到目前为止，我的代码允许我加载到recaptcha演示页面->上，单击“我不是机器人”->点击音频按钮

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("http://localhost/recaptcha-v2/")
# driver.get("https://www.google.com/recaptcha/api2/demo")


WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[src^='https://www.google.com/recaptcha/api2/anchor']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "span#recaptcha-anchor"))).click()
driver.switch_to.default_content()
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[title='recaptcha challenge']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button#recaptcha-audio-button"))).click()


#This works, i can get the captcha token
# Src_URL = driver.find_element_by_id('recaptcha-token').get_attribute('value')

#This does not work, it can't locate the src
WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, "audio-source")))
Src_URL = driver.find_element_by_id('audio-source').get_attribute('src')
print(Src_URL)

请指教谢谢！

我使用下面的代码从src标记中提取audio属性(如果audio标记位于另一个iframe中，则更改iframe )-

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver import ActionChains
import time

driver = webdriver.Chrome()
wait = WebDriverWait(driver, 5)
action = ActionChains(driver)

driver.get("YourURL")

# you can also use time.sleep(5)
wait.until(expected_conditions.presence_of_element_located((By.ID, "audio-source")))
Src_URL = driver.find_element_by_id('audio-source').get_attribute('src')

print(Src_URL)
