使用 Python 访问 Lovoo API

Lovoo 正在使用 OAuth 1 协议 (https://tools.ietf.org/html/draft-hammer-oauth-10)。

我以前使用过 Lovoo API。我可以说的一件事是，您的帐户很快就会受到他们的 BOT 检测算法的限制。我没有尝试使用不同的 HTTP 标头组合。因此，这可能值得一试。

但是，我在 Github 上发布了 my work 供其他人尝试。您可以在下面找到进行 API 调用所需的函数。要查看如何使用这些功能的一些示例，请查看上述 repo。

import urllib.parse


# MD5 hashing of an input string
def md5(data: str):
    import hashlib
    return hashlib.md5(data.encode('utf-8')).hexdigest()


def normalize_params(params: dict):
    # Comply with https://tools.ietf.org/html/draft-hammer-oauth-10
    # params must be sorted alphabetically first by keys and then values
    params = dict(sorted(params.items(), key=lambda x: (x[0], x[1]), reverse=False))
    p_encoded = '&'.join(
        ["{}={}".format(urllib.parse.quote_plus(k), urllib.parse.quote_plus(v)) for k, v in params.items() if v != ''])
    # Percent encode
    p_quoted = urllib.parse.quote_plus(p_encoded)
    return p_quoted


def generate_base_string(params: str, url: str, method: str = 'GET'):
    # Comply with https://tools.ietf.org/html/draft-hammer-oauth-10
    base_str = method + '&' + urllib.parse.quote_plus(url) + '&' + params
    return base_str


# Secret hashing used in Lovoo
def secret_hash(pwd: str) -> str:
    pwd = md5("SALTforPW" + pwd)
    return md5("SALTforSecret" + pwd)


def sign_request(client_identifier: str, client_secret: str, token: str, token_secret: str, url: str, nounce: str,
                 timestamp: str, method: str = 'GET', payload: dict = None, callback_url: str = '', oauth_version: str = '1.0'):
    from hashlib import sha1
    import hmac
    import base64

    params = {
        'oauth_callback': callback_url,
        'oauth_consumer_key': client_identifier,
        'oauth_nonce': nounce,
        'oauth_signature_method': 'HMAC-SHA1',
        'oauth_timestamp': timestamp,
        'oauth_token': token,
        'oauth_version': oauth_version
    }

    # Normalize parameters
    if payload is not None:
        params = {**params, **payload}
    np = normalize_params(params)
    # Generate base string
    base_string = generate_base_string(np, url, method)

    if token != '':
        key = (f"{client_secret}&{token_secret}").encode()
    else:
        key = (client_secret + '&').encode()

    raw = base_string.encode()

    hashed = hmac.new(key, raw, sha1)

    # The signature
    return base64.b64encode(hashed.digest()).decode().rstrip('\n')

请注意，我测试该代码已经有一段时间了，Lovoo 的 API 可能会有一些变化。让我知道它是否不起作用，我会看看。

另一种方法是使用 selenium 进行登录，并进一步使用带有请求的会话。

例如

def login(user, pw):
    chrome_options = Options()
    chrome_options.add_experimental_option("detach", True)
    driver = webdriver.Chrome(options=chrome_options)
    driver.get("https://www.lovoo.com/login_check")
    user_agent = driver.execute_script("return navigator.userAgent;")
    iframe = driver.find_element(By.ID,"gdpr-consent-notice")
    driver.switch_to.frame(iframe)
    privacybutton = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.XPATH,"//b[contains(text(),'Accept All')]"))
    )
    privacybutton.click()
    driver.switch_to.default_content()
    loginbutton = WebDriverWait(driver, 4).until(
        EC.presence_of_element_located((By.XPATH, "//button[contains(text(),'Log in')]"))
    )
    loginbutton.click()
    loginbutton2=WebDriverWait(driver, 4).until(
        EC.presence_of_element_located((By.XPATH, "//button[contains(@data-automation-id,'login-submit-button')]"))
    )
    driver.find_element(By.XPATH, '//input[@name="authEmail"]').send_keys(user)
    driver.find_element(By.XPATH, '//input[@name="authPassword"]').send_keys(pw)
    webdriver.ActionChains(driver).move_to_element(loginbutton2).click(loginbutton2).perform()
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "topmenu"))
    )
    return user_agent, driver.get_cookies()

(lat,lon)=(0.0,0.0)
with requests.Session() as session:
    user_agent, cookies = login(user, pw)
    session.cookies.update({c['name']: c['value'] for c in cookies})
    session.headers.update({'User-Agent': user_agent})
    session.get(f'https://www.lovoo.com/api_web.php/users?ageFrom=0&ageTo=2&latitude={lat}&longitude={lon}')
