ttwid、x-bogus、a-bogus、msToken、byted_acrawler等直播参数说明和获取方式

可以参考开源项目：https://github.com/Sjj1024/douyin-live

桌面端的直播间项目：https://github.com/Sjj1024/LiveBox

ttwid参数

ttwid类似客户端id，即便是游客模式，也可以对页面数据进行埋点统计，通过收集ttwid下的用户行为数据，给与内容推荐和广告推荐。这个也是某节公司下的基础服务，所以生成的id，只要是某节下的服务都可以使用。

获取方式：

从直播间的html中获取

x-bogus参数

x-bogus是一种防数据包伪造的一个参数，又称为x伪造，主要用于反爬虫，这个是某节公司下面基础服务，这个反爬虫机制几乎用在了它所有的产品中，不过，只要是能正常使用，这些东西都是透明的，x-bogus生成算法。

a-bogus：同x-bogus，x-bogus的新版本。

获取方式：

msToken参数

msToken可以理解成Message Token，相当于每次消息请求的令牌，主要用于请求统计，这也是具有反爬虫的机制，如果相同msToken请求太多，也会被定义成恶意请求，这时候会出现验证码校验。所以我们在使用的时候，可以用uuid或者是雪花算法的id来模拟msToken，当然长度大于32位的唯一串最好。

获取方法如下：

    def get_ms_token(self, randomlength=107):
        """
        根据传入长度产生随机字符串
        """
        random_str = ''
        base_str = 'ABCDEFGHIGKLMNOPQRSTUVWXYZabcdefghigklmnopqrstuvwxyz0123456789='
        length = len(base_str) - 1
        for _ in range(randomlength):
            random_str += base_str[random.randint(0, length)]
        return random_str

signature参数

signature是签名，主要是防止数据传输的过程中，“中间人”对数据进行串改。签名一般都是公钥加密，私钥验签。参与签名的参数有url地址中的参数，还有post请求中的内容，也会参与签名。signature主要用于post或者put表单的时候进行使用，其他情况暂时未遇到。

获取方式：

def get_signature(x_ms_stub):
    try:
        ctx = jsengine.jsengine()
        js_dom = f"""
document = {{}}
window = {{}}
navigator = {{
'userAgent': '{USER_AGENT}'
}}
""".strip()
        js_enc = load_webmssdk('webmssdk.js')
        final_js = js_dom + js_enc
        ctx.eval(final_js)
        function_caller = f"get_sign('{x_ms_stub}')"
        signature = ctx.eval(function_caller)
        # print("signature: ", signature)
        return signature
    except:
        logger.exception("get_signature error")
    return "00000000"

__ac_nonce：临时加密参数，用于与_signature一起使用

webid：同ttwid，类似客户端id，也可以说是浏览器id，不过ttwid可在cookie获取，webid可在随意一个视频请求，返回的html文本的script里再通过正则获取：

    def get_ttwid_webid(self, req_url):
        """
        获取 ttwid 和 webid
        :param req_url:请求的视频地址
        :return:
        """
          while True:
            try:
                headers = {
                    "User-Agent":'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36',

                }
 
                response = requests.request("GET", req_url, headers=headers, verify=False, timeout=3)
                cookies_dict = response.cookies.get_dict()
                ttwid_str = cookies_dict.get('ttwid')

                re.compile('\<script id=\"RENDER_DATA\" type\=\"application\/json\">(.*?)\<\/script\>').findall(
                    response.text)
                if(render_data_text):
                    render_data_text=render_data_text[0]
                    render_data_text = requests.utils.unquote(render_data_text)
                    render_data_json = json.loads(render_data_text, strict=False)
                    webid = render_data_json.get('app').get('odin').get('user_unique_id')
                    return ttwid_str, webid
            except Exception as e:
                logging.error(e)
                time.sleep(1)

直播地址和主播信息

可以从直播的heml中提取到主播的信息和直播状态，还可以获取到直播流地址，提取方式就是正则表达式获取到json信息，使用rust代码如下：


    pub async fn get_room_info(&mut self) -> Result<LiveInfo, Box<dyn std::error::Error>> {
        println!("获取直播间的room_info: {}", self.room_url);
        let mut headers = reqwest::header::HeaderMap::new();
        headers.insert("accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7".parse()?);
        headers.insert("accept-language", "zh-CN,zh;q=0.9,en;q=0.8".parse()?);
        headers.insert("cache-control", "max-age=0".parse()?);
        headers.insert("cookie", "has_avx2=null; device_web_cpu_core=8; device_web_memory_size=8; live_use_vvc=%22false%22; xgplayer_user_id=903249300469; csrf_session_id=e2291ffdef635bf0666cf1a399de55de; webcast_local_quality=sd; SEARCH_RESULT_LIST_TYPE=%22single%22; bd_ticket_guard_client_web_domain=2; passport_csrf_token=644447c8fab148b9d360fdda67a1c4f8; passport_csrf_token_default=644447c8fab148b9d360fdda67a1c4f8; passport_assist_user=Cj2OyRQMJT-e_Yzf449bZPEv0yUeH6BvdNRi_8h6CtjL9f25qppJm9BSLatEfMUCnczMIxVgMYDWHw364CG_GkoKPOLAdamXQxwSIWj12fJ2HNDAzmKpcbYG_dL6XR46fpnifsYZHT0z_Z_o1N8bgNfGp2ung2BIO__buAxCBRCn0s4NGImv1lQgASIBA6XIvQ8%3D; n_mh=nNwOatDm453msvu0tqEj4bZm3NsIprwo6zSkIjLfICk; sso_uid_tt=25ba3d5cf4d058bf184ba57854a3853e; sso_uid_tt_ss=25ba3d5cf4d058bf184ba57854a3853e; toutiao_sso_user=561cc4c4cf742716616ebfd519d93768; toutiao_sso_user_ss=561cc4c4cf742716616ebfd519d93768; sid_ucp_sso_v1=1.0.0-KDUwODgyZmE5YzRjZGYxYjM2ZDE4ZDM5OWY3NDBiZGM4ZmE3YmFiM2MKHwj1jJ219wIQzs7vsAYY7zEgDDD-jcTZBTgGQPQHSAYaAmhsIiA1NjFjYzRjNGNmNzQyNzE2NjE2ZWJmZDUxOWQ5Mzc2OA; ssid_ucp_sso_v1=1.0.0-KDUwODgyZmE5YzRjZGYxYjM2ZDE4ZDM5OWY3NDBiZGM4ZmE3YmFiM2MKHwj1jJ219wIQzs7vsAYY7zEgDDD-jcTZBTgGQPQHSAYaAmhsIiA1NjFjYzRjNGNmNzQyNzE2NjE2ZWJmZDUxOWQ5Mzc2OA; passport_auth_status=854512750fb9b055d3809c2222eba72c%2C; passport_auth_status_ss=854512750fb9b055d3809c2222eba72c%2C; uid_tt=66858707d0775da51ae9674c1c591c27; uid_tt_ss=66858707d0775da51ae9674c1c591c27; sid_tt=c5061d6aae3b61f174b0c0696c6b7418; sessionid=c5061d6aae3b61f174b0c0696c6b7418; sessionid_ss=c5061d6aae3b61f174b0c0696c6b7418; _bd_ticket_crypt_doamin=2; _bd_ticket_crypt_cookie=bfcf62e1ae0bb79801498b683a86f505; __security_server_data_status=1; sid_guard=c5061d6aae3b61f174b0c0696c6b7418%7C1713104723%7C5183998%7CThu%2C+13-Jun-2024+14%3A25%3A21+GMT; sid_ucp_v1=1.0.0-KDY3ZWE2NzI3NDg3NjFjOWFlZjQ1ZmE0ZDE0OGI5NTY5NmYyMmE3MTcKGQj1jJ219wIQ087vsAYY7zEgDDgGQPQHSAQaAmxxIiBjNTA2MWQ2YWFlM2I2MWYxNzRiMGMwNjk2YzZiNzQxOA; ssid_ucp_v1=1.0.0-KDY3ZWE2NzI3NDg3NjFjOWFlZjQ1ZmE0ZDE0OGI5NTY5NmYyMmE3MTcKGQj1jJ219wIQ087vsAYY7zEgDDgGQPQHSAQaAmxxIiBjNTA2MWQ2YWFlM2I2MWYxNzRiMGMwNjk2YzZiNzQxOA; s_v_web_id=verify_luzmbzzg_wsuYknjY_Tc27_468O_9tHB_sKsLLWh3qV2R; ttwid=1%7CngabJA52sDUnYMxFKTFQmYEe2_RYNkefWVWEfuA53Mo%7C1713104743%7C34512c898d125865794d949a2477dda7493530c850da7c59a19c32a46642876c; LOGIN_STATUS=1; store-region=cn-sh; store-region-src=uid; publish_badge_show_info=%220%2C0%2C0%2C1714188960632%22; volume_info=%7B%22isUserMute%22%3Afalse%2C%22isMute%22%3Atrue%2C%22volume%22%3A0.6%7D; stream_recommend_feed_params=%22%7B%5C%22cookie_enabled%5C%22%3Atrue%2C%5C%22screen_width%5C%22%3A1470%2C%5C%22screen_height%5C%22%3A956%2C%5C%22browser_online%5C%22%3Atrue%2C%5C%22cpu_core_num%5C%22%3A8%2C%5C%22device_memory%5C%22%3A8%2C%5C%22downlink%5C%22%3A10%2C%5C%22effective_type%5C%22%3A%5C%224g%5C%22%2C%5C%22round_trip_time%5C%22%3A200%7D%22; strategyABtestKey=%221714189004.807%22; webcast_leading_last_show_time=1714189045348; webcast_leading_total_show_times=6; __live_version__=%221.1.1.9879%22; FOLLOW_LIVE_POINT_INFO=%22MS4wLjABAAAAdWaAD1s4nTXy5AWB9YQOjjVuEBSdF9Ke149hLM64PdY%2F1714233600000%2F0%2F0%2F1714215078555%22; FOLLOW_NUMBER_YELLOW_POINT_INFO=%22MS4wLjABAAAAdWaAD1s4nTXy5AWB9YQOjjVuEBSdF9Ke149hLM64PdY%2F1714233600000%2F0%2F1714214478555%2F0%22; passport_fe_beating_status=true; download_guide=%223%2F20240427%2F0%22; home_can_add_dy_2_desktop=%221%22; pwa2=%220%7C0%7C3%7C0%22; __ac_nonce=0662cd7bb00365383c41; __ac_signature=_02B4Z6wo00f01CXmuJwAAIDDdxmYhyaqaAglxrwAAG9c5BKd035mkv0aWuHT5.B6XgeFC-vvGuX4JgBV0ExZ0N.P5fFlhkfuwOam9askMq120O4j4k80SiSu9eVCx7llvUbc0L38xoSU.Iztae; xg_device_score=7.4571195567119375; live_can_add_dy_2_desktop=%221%22; bd_ticket_guard_client_data=eyJiZC10aWNrZXQtZ3VhcmQtdmVyc2lvbiI6MiwiYmQtdGlja2V0LWd1YXJkLWl0ZXJhdGlvbi12ZXJzaW9uIjoxLCJiZC10aWNrZXQtZ3VhcmQtcmVlLXB1YmxpYy1rZXkiOiJCRHpRSzBPc3RkRE5EOEIxVVM2QUhibjFxeGFEK0FCYkljbmMzeWxwMC9ZVE5SVks4cUZQTEtTSFRjbGtZdys2NnlpR1hEdDVsT05XaHd6UDFScWUrbUE9IiwiYmQtdGlja2V0LWd1YXJkLXdlYi12ZXJzaW9uIjoxfQ%3D%3D; msToken=dkS_SWd4Y0gsRB3GqURAf762ahdZlFp8lnIe5X99t-lSKMPg7ly9UIa4MZtcIS6gtJS_GkR2qE_V3WZfqOihnoDO2Td2BZlE0ZTYfHzH3memmRkD256iF9-MJUWi; odin_tt=441e6d35a29801763dc3805e40897a3197ad8eb3dede1b88ebda81998f313f13820db809f050a325915ac1347cb213ba; IsDouyinActive=false; msToken=ckrB5duL8xVXFP110HedaLvZk2iXY6ADOnnYAk3wQiInRW7veHIyuMdqd47VCyM-wNyW6ZpY6f7YqTH4Hwrwne--fd8bLF9qLOWgvIB3MG47BhPkkBNiDL77xuyU; ttwid=1%7CngabJA52sDUnYMxFKTFQmYEe2_RYNkefWVWEfuA53Mo%7C1713104743%7C34512c898d125865794d949a2477dda7493530c850da7c59a19c32a46642876c".parse()?);
