QQ音乐vkey获取,更新播放url

QQ音乐接口播放经常换，

最开始

url: `http://ws.stream.qqmusic.qq.com/${musicData.songid}.m4a?fromtag=46`

然后

url:`http://ws.stream.qqmusic.qq.com/C100${musicData.songmid}.m4a?fromtag=0&guid=126548448`

现在

url: `http://dl.stream.qqmusic.qq.com/C400${musicData.songmid}.m4a?fromtag=38&guid=5931742855&vkey=${vkey}`

vkey的获取

// 获取歌曲的vkey
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`
    })

    return jsonp(url, data)
}

　调用

    //重组 res.data.list 数据,只拿需要的
    _formatSongs(list){
      let result = []
      list.forEach((item)=>{
        // console.log('item',item)
        // 解构赋值-拿到item 下的 musicData 列表数据
        let {musicData} = item
        //------------- 更新的加上vkey
        getSongVkey(musicData.songmid).then((res) => {
          const vkey = res.data.items[0].vkey;
          if (musicData.songid && musicData.albummid) {
            result.push(CreatSong(musicData, vkey))
          }
        })
        //-------------
        // console.log('musicData',musicData)
        // if(musicData.songid && musicData.albummid){
        //   result.push(CreatSong(musicData))
        // }
      })
      return result
    }

export function CreatSong(musicData,vkey){ //加了一个传参和更新了url
    return new Song({
        id: musicData.songid,
        mid: musicData.songmid,
        singer: filterSinger(musicData.singer),//filterSinger 中处理一遍
        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=${vkey}`
    })
}

调用调试完成！
