如何使用Selenium和Python请求以编程方式识别ReCaptcha V2的32位data-sitekey以获取有效的响应?

selenium

验证码和Python请求几乎是新的。验证码文档说要复制data-sitekey参数的值。

这是我的尝试,使用Selenium打开url并使用Pythonrequests获得响应。

mainurl = 'https://imagetyperz.xyz/automation/recaptcha-v2.html'
driver.get(mainurl)
data_sitekey_class = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, "g-recaptcha"))).get_attribute("data-sitekey")
print(data_sitekey_class)
src_css_selector = driver.find_element_by_css_selector("iframe[role='presentation']").get_attribute("src")
print(src_css_selector)
keygoogle = src_css_selector[52:92]
print('Site Key = ', keygoogle)
data_post = {'key': data_sitekey_class, 'method': 'userrecaptcha', 'googlekey': keygoogle, "pageurl": mainurl}
response = requests.post(url = 'https://2captcha.com/in.php', data = data_post )
print(response)
print(response.text)

我得到200回应:

6LdXeIYUAAAAAFmFKJ6Cl3zo4epRZ0LDdOrYsvRY
https://www.google.com/recaptcha/api2/anchor?ar=1&k=6LdXeIYUAAAAAFmFKJ6Cl3zo4epRZ0LDdOrYsvRY&co=aHR0cHM6Ly9pbWFnZXR5cGVyei54eXo6NDQz&hl=en&v=vJuUWXolyYJx1oqUVmpPuryQ&size=normal&cb=r14cgu7t25ul
Site Key =  6LdXeIYUAAAAAFmFKJ6Cl3zo4epRZ0LDdOrYsvRY
<Response [200]>
ERROR_WRONG_USER_KEY

这是由于:

ERROR_WRONG_USER_KEY

此外,“ 错误”部分提到:

Error code: ERROR_WRONG_USER_KEY
Description: You've provided key parameter value in incorrect format, it should contain 32 symbols.
Action: Stop sending requests. Check your API key.

最后,解决验证码部分提到:

从帐户设置页面获取API密钥。每个用户都有一个唯一的身份验证令牌,我们称其为API密钥。这是一个32个字符的字符串,如下所示:

1abc234de56fab7c89012d34e56fa7b8

凡为data-sitekey我看到的是:

6LdXeIYUAAAAAFmFKJ6Cl3zo4epRZ0LDdOrYsvRY

这是 41 位。

我要去哪里错了?

data-sitekey通过41个字符的字符串表示的效果很好。ERROR_WRONG_USER_KEY发生错误是因为我一开始从未准备好有效的API密钥。即使您的帐户余额为零 ,您也可以按以下方式成功获取<Response [200]>带有文本的ERROR_ZERO_BALANCE

    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
    import requests

    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’)
    mainurl = ‘https://imagetyperz.xyz/automation/recaptcha-v2.html'
    driver.get(mainurl)
    data_sitekey = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, “g-recaptcha”))).get_attribute(“data-sitekey”)
    print(data_sitekey)
    api_key = ‘--------------------------------‘
    data_post = {‘key’: api_key, ‘method’: ‘userrecaptcha’, ‘googlekey’: data_sitekey, “pageurl”: mainurl}
    response = requests.post(url = 'https://2captcha.com/in.php’, data = data_post )
    print(response)
    print(response.text)

  • 控制台输出:

    ERROR_ZERO_BALANCE
