抓包接口分析

主要是需要这一块的内容通过抓包分析发现在html中直接有json数据现在只需要请求页面然后提取出需要的json数据即可，现在重点分析一下请求所需的参数，经过测试得知，ttwid是必要参数，看长度和验证流程和dy极为相似，直接用dy的套一下测试发现是一样的。

cookies = {

   # "tt_webid": "7221851119085061689",

   # "_ga": "GA1.1.1371017124.1681468304",

   # "passport_csrf_token": "086bf595bf03413a64b6250e818f8861",

   "s_v_web_id": "verify_ljcqae1y_flG7UGHi_j6mx_4ZjM_8dt3_z9Lxvp74pqk5"

}

ttwid生成

验证流程：1.先获取ac_nonce 2.根据ac_nonce本地生成ac_signature 3.使用ac_nonce和__ac_signature 获取ttwid

headers_base = {

   # sess.mount(url , CipherAdapter())

   __ac_nonce = sess.get(url, headers=headers_base).cookies.get('__ac_nonce')

   __ac_signature = get_ac_sign(__ac_nonce)

   }

   ttwid = requests.get(headers=headers).cookies.get('ttwid')

   print(ttwid)
