B 站直播预约抽奖协议—Python

一、抓包

1.1 直播预约包

直播预约链接

POST 请求  https://api.bilibili.com/x/dynamic/feed/reserve/click?csrf=46378a87cb7283a133e9c32b9c09bee7

原始表单数据 {“reserve_id”:4073369,”cur_btn_status”:1,”dynamic_id_str”:”976127207527153680″,”reserve_total”:25439,”spmid”:””}

{
“cur_btn_status”: 1,
“dynamic_id_str”:”976127207527153680″,
“reserve_id”: 4073369,
“reserve_total”: 25439,
“spmid”: “”
}

cur_btn_status——1：预约  2：取消预约

dynamic_id_str——直播预约的链接后面的 id

reserve_id——直播间 id

reserve_total——已预约人数

响应结果示例

 1.2 直播 reserve_id、reserve_total 获取包

只需要 GET 直播预约的链接即可在响应中找到

本文使用的是 https://www.bilibili.com/opus/976127207527153680

响应中还有直播的时间，标题

reserve_total——reserve_total

rid——reserve_id

二、批量获取动态抽奖的思路

三、Python 代码实现

2.1reserve_id、reserve_total 获取

def get_bilibili_opus(cookie,articalid):L
    url = 'https://www.bilibili.com/opus/{articalid}'
    headers = {
        'Host': 'www.bilibili.com',
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:130.0) Gecko/20100101 Firefox/130.0',

        'Referer': 'https://www.bilibili.com/',
        'Connection': 'keep-alive',
        'Cookie': cookie  # cookie
    }
    response = requests.get(url, headers=headers)
    if response.status_code == 200:
        return response.text  # 返回HTML内容
    else:
        return "获取失败"

2.2 直播预约

    try:

            headers['Cookie'] = cookie_string
        session = requests.Session()
        response = session.post(url, data=data, headers=headers)
        print(f'状态码: {response.status_code}')
        if response.status_code == 200:
            try:
                if 'gzip' in response.headers.get('Content-Encoding', ''):
                    response_data = gzip.decompress(response.content).decode('utf-8')
                else:
                    response_data = response.text
                print("参与成功")
                try:

        else:
