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！
