抓包接口分析

主要是需要这一块的内容
在这里插入图片描述
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",

}

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
