# print(r.text)
#第一步，访问网页获取MusicID
p = re.compile(r"MusicId=(.*?);",re.S)
print(re.search(p,response.text).group())

运行得到如下，获取到MusicId

#第一步，访问网页获取MusicID
p = re.compile(r"MusicId=(.*?);",re.S)
music_id = re.search(p,response.text).group(1)
#第二步 nodejs生成mp3 url
with open('m.js',encoding='utf-8') as f:
    ctx = execjs.compile(f.read())
    t = ctx.call("info", music_id)
    print(t)
#第三步 访问mp3 url,下载MP3并保存

function info(MusicId){

        nurl = parseInt(MusicId / 30000) + "/" + parseInt(MusicId / 2000) + "/" + MusicId + ".mp3";
        fin_url = surl + nurl
        return fin_url
