Python 使用服务解决验证码时遇到问题

我用一些什么硬编码的方法获取站点密钥，但是由于len总是相同的，所以没关系。 之后，我使用，以便我可以张贴的关键，并获得令牌验证码回来。我面临两大问题： 1） 我总是错误地获取站点密钥，但根据他们的示例，站点密钥是正确的（他们的站点密钥长度为40个字符，我的站点密钥也为40个字符） 2） 我尝试在外部创建一个POST函数，并尝试查看它是否是一个bug，但是使用文档我总是会得到以下错误： 这是验证码密钥抓取

#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Captcha Key~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
url=driver.find_element_by_css_selector("iframe[role='presentation']").get_attribute('src')
print(url)
keygoogle = url[53:93]
print('Site Key = ', keygoogle)

这是验证码密钥解析块：

answer = ""
answer_id = 0
api_key = '--------------------------------'
data_post = {'key': api_key, 'method': 'userrecaptcha', 'googlekey': keygoogle, "pageurl": mainurl}
response = requests.post(url = 'https://2captcha.com/in.php', data = data_post )
print(response)
print("Waiting for server response.")
for x in range(15):
    time.sleep(1)
    if x == 5:
        print('Downloading info..')
    elif x == 10:
        print('Processing info..')
    elif x == 14:
        print('Solving captcha..')
data_request = {
    'key': api_key,
    'action': answer,
    'id': answer_id,
}
requests.get(url ='https://2captcha.com/res.php', data=data_request)
print(answer)

def captcha():
    google_key = keygoogle
    url = mainurl
    client = TwoCaptchaClient(client_key=api_key)
    task = GoogleReCaptchaV2Task(googlekey=google_key, pageurl=mainurl)
    job = client.create_task(task)
    token = job.get_solution_response()
    return token
print(captcha())

我没有包括的是令牌被发布到答案字段的部分，我不知道怎么做，但我会找到一个确定的方法

编辑： 这是我从打印中获得的值：

这是我从

print（'Site Key='，keygoogle）

---

Site Key=Lc3HAsUAAAAACsN7CgY9MMVxo2M09n\u e4heJEiZ&该Site Key末端的&肯定不应该在那里。使用正则表达式，而不是在索引中执行的操作。

这是我获取正确键的方法：

    url=driver.find_element_by_css_selector("iframe[role='presentation']").get_attribute('src')
keygoogle = url[52:92]

这是我的POST功能：

#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Captcha Solve~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
answer = ""
answer_id = 0
data_post = {'key': api_key, 'method': 'userrecaptcha', 'googlekey': keygoogle, "pageurl": mainurl}
response = requests.post(url = 'https://2captcha.com/in.php', data = data_post )
response = response.text[3:]
print("Waiting for server response.")
for x in range(30):
    time.sleep(1)
    if x == 8:
        print('Downloading info..')
    elif x == 15:
        print('Processing info..')
data_request = {'key': api_key,'id': int(response),'action': 'get'}
response = requests.get(url='https://2captcha.com/res.php', params=data_request)
token = response.text.split('|')[0]
while response.text == 'CAPCHA_NOT_READY':
    print('Waiting for Capcha..')
    time.sleep(5)
    response = requests.get(url='https://2captcha.com/res.php', params=data_request)
    token = response
print(token)
