方法一###(有点问题)

利用axios伪造，抓取的网页版qq音乐的接口，但这个接口有瑕疵…能获取到Vkey，但不是每一首歌曲都能正常播放…后来发现网页版音乐中每个歌曲的播放地址的域名不是都一样的，不能播放的歌曲有可能是这个接口不对…还没找到解决办法

song.js

export function createSong(musicData, songVkey) {
  return new Song({
    id: musicData.songid,
    mid: musicData.songmid,
    singer: filterSinger(musicData.singer),
    name: musicData.songname,
    album: musicData.albumname,
    duration: musicData.interval,
    image: `https://y.gtimg.cn/music/photo_new/T002R300x300M000${musicData.albummid}.jpg?max_age=2592000`,
    url: `http://isure.stream.qqmusic.qq.com/C400${musicData.songmid}.m4a?guid=9244517832&vkey=${songVkey}&uin=0&fromtag=66`
  })
}

singer.js

export function getSongVkey(songmid) {
  const url = '/api/getSongVkey'
  const data = Object.assign({}, commonParams, {
    songmid: songmid,
    notice: 0,
    platform: 'yqq.json',
    needNewCode: 0,
    format: 'json',
    data: {"req_0":{"module":"vkey.GetVkeyServer","method":"CgiGetVkey","param":{"guid":"9244517832","songmid":["001Qu4I30eVFYb"],"songtype":[0],"uin":"0","loginflag":1,"platform":"20"}},"comm":{"uin":0,"format":"json","ct":24,"cv":0}}
  })
  return axios.get(url, {
    params: data
  }).then((res) => {
    return Promise.resolve(res.data)
  })
}

webpack.dev.config

app.get('/api/getSongVkey', function (req, res) {
          var url = 'https://u.y.qq.com/cgi-bin/musicu.fcg'
          axios.get(url, {
            headers: {
              referer: 'https://u.y.qq.com/',
              host: 'u.y.qq.com'
            },
            params: req.query
          }).then((response) => {
            res.json(response.data)
          }).catch((e) => {
            console.log(e)
          })
        })

singer-detail

_normallizeSongs(list, callback) {
        let ret = []
        let index = 1
        list.forEach((item) => {
          let {musicData} = item // 得到music对象
          if (musicData.songid && musicData.albummid) {

                ret.push(newSong)
                if (index === list.length) {
                  callback && callback(ret)
                }
                index ++
              }
            })
          }
        })
      }   

方法二###(实测没有问题)

这个是抓取的是h5版qq音乐的jsonp接口
singer.js

export function getSongVkey(songmid) {
  const url = 'https://c.y.qq.com/base/fcgi-bin/fcg_music_express_mobile3.fcg'
  const data = Object.assign({}, {
    callback: 'musicJsonCallback',
    loginUin: 3051522991,
    format: 'jsonp',
    platform: 'yqq',
    needNewCode: 0,
    cid: 205361747,
    uin: 3051522991,
    guid: 5931742855,
    songmid: songmid,
    filename: `C400${songmid}.m4a`
  })

song.js

export function createSong(musicData, songVkey) {
  return new Song({
    id: musicData.songid,
    mid: musicData.songmid,
    singer: filterSinger(musicData.singer),
    name: musicData.songname,
    album: musicData.albumname,
    duration: musicData.interval,
    image: `https://y.gtimg.cn/music/photo_new/T002R300x300M000${musicData.albummid}.jpg?max_age=2592000`,
    url: `http://dl.stream.qqmusic.qq.com/C400${musicData.songmid}.m4a?fromtag=38&guid=5931742855&vkey=${songVkey}`
  })
}

singer-detail

_normallizeSongs(list) {
        let ret = []
        list.forEach((item) => {
          let {musicData} = item // 得到music对象
          getSongVkey(musicData.songmid).then((res) => {
            const songVkey = res.data.items[0].vkey
            if (musicData.songid && musicData.albummid) {
              ret.push(createSong(musicData, songVkey))
            }
          })
        })
        console.log(ret)
        return ret
      }
