本文内容： 在QQ空间领域中需要使用的g_tk算法

介绍：g_tk是腾讯在QQ空间这一领域使用的密文（其他的地方我没遇到g_tk）。调用其url时，需要添加计算出的g_tk参数才能成功！

使用

def get_g_tk(cookie):
    hashes = 5381
    for letter in cookie.split(';')[-1].split('=')[-1]:
        hashes += (hashes << 5) + ord(letter)
    g_tk = hashes & 0x7fffffff
    return g_tk

比如获得

## get_data
def fetch_like_number_data(cookie, Id):
    if not itemId:
        raise ValueError("id does not exist")

    g_tk = get_g_tk(cookie)
    url = f'https://vip.qq.com/vbs/n_UniBusinessCollectObj/nCollectInfo?Id=999&g_tk={g_tk}'

    stLo = {
        "iKeyType": 1,
        "iOpplat": 1,
        "sClientIp": "",
        "sClientVer": "undefined.undefined.undefined",
        "sSKey": "string"
   }

    query_param = {
        "stLogin": stLo,
        "stUniBusinessItemList":  ["1"],

    }
    a_headers = {
        'User-Agent': user_agent,
        'Cookie': cookie,
        'Content-Type': 'application/json; charset=utf-8',
    }

    chick_url = f'https://vip.qq.com/vbs/b_UniBusinessLogicObj/uC?Id=888&g_tk={g_tk}'
    dumps = json.dumps(query_param)
    requests.post(url=chick_url, data=dumps, headers=a_headers)
    a_response = requests.post(url=a_url, data=dumps, headers=a_headers)

    a_json = json.loads(a_response.text)
    # 数据
    a_num = a_json['data']['stRsp']['stItemCollectInfoList'][0]['cnt']
    print(a_num)
    return a_num
    ```
