原链 就存在 html 里面，没有什么花头。

web_session 和 webid X-T X-S 有关系，

import requests

session = requests.Session()
time_sjc = str(round(time.time() * 1000))
hex_string = ''.join(random.choices('0123456789abcdef', k=32))

headers_sess = {
    'Host': 'edith.xiaohongshu.com',
    'Cookie': f'webId={hex_string}',
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/111.0.0.0 Safari/537.36',
    'X-T': '1678954686651',
    'X-S': 'O65K0gMpZ2wv0gTLOjUUs6MLsl9lZjVUsl5+Z6TiOlA3',
}

session.post("https://edith.xiaohongshu.com/api/sns/web/v1/login/activate",headers=headers_sess,data='{}')
print(session.cookies.get_dict())

cookie 的获取

f12 开发者工具， 找到 network 或者 网络，f5 刷新页面，翻一下 cookie 很长的就是

脚本
