Python音乐下载

今天跟大家分享一款QQ音乐的下载器

主要的原理：

当我们分析网页数据后可以得到下面三个接口

self.search_url = 'https://c.y.qq.com/soso/fcgi-bin/client_search_cp?ct=24&qqmusic_ver=1298&new_json=1&remoteplace=txt.yqq.top&searchid=34725291680541638&t=0&aggr=1&cr=1&catZhida=1&lossless=0&flag_qc=0&p=1&n=20&w={}&g_tk=5381&jsonpCallback=MusicJsonCallback703296236531272&loginUin=0&hostUin=0&format=jsonp&inCharset=utf8&outCharset=utf-8&notice=0&platform=yqq&needNewCode=0'
self.fcg_url = 'https://c.y.qq.com/base/fcgi-bin/fcg_music_express_mobile3.fcg?g_tk=5381&jsonpCallback=MusicJsonCallback9239412173137234&loginUin=0&hostUin=0&format=json&inCharset=utf8&outCharset=utf-8&notice=0&platform=yqq&needNewCode=0&cid=205361747&callback=MusicJsonCallback9239412173137234&uin=0&songmid={}&filename={}.m4a&guid=8208467632'
self.downloader_url = 'http://dl.stream.qqmusic.qq.com/{}.m4a?vkey={}&guid=8208467632&uin=0&fromtag=66'

1、第一个接口需要根据歌曲名构造完整链接来搜索需要下载的歌曲信息

2、第二个接口需要根据第一个接口返回的信息来构造完整链接来获取歌曲下载地址的部分信息

3、第三个接口即为歌曲下载地址，需要根据前两个接口获取的信息来构造完整链接
