ReCaptcha 下载音频文件？

Question

请让我知道我做错了什么

使用来自：How to interact with the reCAPTCHA audio element using Selenium and Python的代码

我想下一步获取音频的 src 文件以下载它，所以我在提供的代码结束后准确地写了以下内容：

# get the mp3 audio file
src = driver.find_element_by_id("audio-source").get_attribute("src")

但是 Python 返回运行时错误：

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="audio-source"]"}
  (Session info: chrome=88.0.4324.96)

注意：我照原样复制了该代码，只添加了最后一行

为了让您信服，这里是我的完整代码：

def tmp():
    from selenium.webdriver.common.keys import Keys

    # recaptcha libraries
    import speech_recognition as sr
    import urllib
    # import pydub

    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='/Users/ahmad/Desktop/chromedriver')
    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()

    # get the mp3 audio file
    src = driver.find_element_by_id("audio-source").get_attribute("src")

我在附近的元素上尝试了以下以获得它的 href 值并且它有效，我唯一的问题是上面的内容：

src=WebDriverWait(driver, 10).until(
    EC.element_to_be_clickable((By.CSS_SELECTOR, "a.rc-audiochallenge-tdownload-link"))).text

src=src.get_attribute('href')

print(src)

它处理的元素是：

我也试过这个：

src=WebDriverWait(driver, 10).until(
    EC.invisibility_of_element((By.XPATH, "//*[@id=\"audio-source\"]")))

src=src.get_attribute('src')

但我得到一个错误：

src=src.get_attribute('src')

AttributeError: 'bool' 对象没有属性 'get_attribute'

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()
WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.CSS_SELECTOR, ".rc-audiochallenge-play-button button")))

# get the mp3 audio file

src = driver.find_element_by_id("audio-source").get_attribute("src")
print(src)

只需为 .rc-audiochallenge-play-button 按钮再添加一个 wiat

下载你应该使用：

import urllib.request
urllib.request.urlretrieve(src, "src.mp3")
