qq音乐排行榜数据爬取

废话不多说，直接上教程

https://u.y.qq.com/cgi-bin/musicu.fcg?format=json&inCharset=utf8&outCharset=utf-8platform=yqq.json&needNewCode=0&data={“detail”:{“module”:“musicToplist.ToplistInfoServer”,“method”:“GetDetail”,“param”:{“topId”:26,”offset”:0,“num”:20,“period”:“2019-12-20”}}}
其中topId为榜单id，period为日期，num为获取榜单歌曲数，基于这些信息，我们通过修改这三个参数就可以很轻易地获取其他榜单的任意日期的数据，获取之后通过json解析工具即可获取榜单中的歌曲信息，下面以qq流行指数榜为例，上源码。
