7、爬虫-爬取音乐

1、查找请求音乐播放的请求 url地址：以酷我音乐为例

  拿到url 对url进行分析 ：https://www.kuwo.cn/api/v1/www/music/playUrl?mid=326968713&type=music&httpsStatus=1&reqId=bf6ff0b0-acb0-11ee-bf9b-c39de8563da8&plat=web_www&from=

  mid = 不同歌曲的id

  type = 音乐的类型、type=mp3 

  httpsStatus  状态码

  reqId  不知道作用

2、查找html里不同音乐 的标签里有无类型 id的数字

更换url的mid试试：看是否能对应歌曲

https://www.kuwo.cn/api/v1/www/music/playUrl?mid=330465682&type=music&httpsStatus=1&reqId=bf6ff0b0-acb0-11ee-bf9b-c39de8563da8&plat=web_www&from=

将type改为 type=mp3就可以下载付费音乐了
