)3.处理响应，找到mp4，一层一层剥离
res = response.json()
url_list = res.get('aweme_list')
# print(url_list[1])
for i in url_list:
url = i.get('video').get('play_addr').get('url_list')[0]
print("url:",url)4.查看请求参数，含sec_user_id和X-Bogus,重点学习如何po解X-Bogus
找到对应行代码，打断点，切换条件断点，增加条件：
_0xc26b5e.openArgs[1].search("aweme/v1/web/aweme/post/")>=0
切换为日志断点,_0x2458f0['apply'](_0xc26b5e, _0x1f1790)，输出结果
在切换为条件断点，如果结果长度大于等于28位即可.length ==28
在找到对应的函数，直接把全部js文件复制到pycharm
然后给对应函数设置为全局函数：
winodws.yyh = 函数名
userid="" #这里要传userid
然后最下面打印Windows.yyh(userid,null)
5.后面再py文件里面解析js文件，把userid传过去，并拿到x-bogus
