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",

}
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
