前阵子过年的时候参加新春厨神大作战,发了上百来条动态。
现在看着挺碍眼的,决定批量删除。

代码

如下,改下cookie即可

import requests,json,re


def get_dynamics(uid:str, cookie:str, offset_dynamic_id:int = 0):
    result = _http_get_dynamics(uid, cookie, offset_dynamic_id)
    while result["data"]["has_more"] == 1:
        for card in result["data"]["cards"]:
            # 请注意,返回的json里面有很多id、rid、dynamic_id、dynamic_id_str之类的,请取用dynamic_id_str
            yield card["desc"]["dynamic_id_str"], json.loads(card["card"])
        offset_dynamic_id = result["data"]["next_offset"]
        result = _http_get_dynamics(uid, cookie, offset_dynamic_id)

def _http_get_dynamics(uid, cookie, offset_dynamic_id = 0):
    headers = {
        "Accept": "application/json, text/plain, */*",
        "User-Agent": user_agent,
        "Accept-Encoding": "gzip, deflate",
        "Cookie": cookie,
    }
    url = "https://api.vc.bilibili.com/dynamic_svr/v1/dynamic_svr/space_history?visitor_uid=%s&host_uid=%s&offset_dynamic_id=%d&need_top=1&platform=web"%(uid, uid, offset_dynamic_id)
    res = requests.get(url, headers=headers).json()
    return res
    
def delete_dynamic(uid:str, dynamic_id_str:str, cookie):
    # {'code': 500406, 'msg': '不能删除别人的动态哦', 'message': '不能删除别人的动态哦', 'data': {}}
    # {'code': 500404, 'msg': '不能重复删除', 'message': '不能重复删除', 'data': {}}
    # {'code': 0, 'msg': '', 'message': '', 'data': {'_gt_': 0}}
    regexs = re.search("bili_jct=([^&; =]+)", cookie)
    if not regexs:
        raise Exception("cookie not valid")
        
    csrf_token = regexs.group(1)
    headers = {
        "Accept": "application/json, text/plain, */*",

    url = "https://api.vc.bilibili.com/dynamic_svr/v1/dynamic_svr/rm_dynamic"
    res = requests.post(url, data=data, headers=headers, verify=True).json()
    return res
