获取外链

http://music.163.com/song/media/outer/url?id=165237.mp3

只需要将上述地址的id改为音乐id即为外链地址

使用axios爬取歌单

具体思路：先get到歌单页面地址，然后使用正则匹配歌单的DOM元素，提取歌曲id与名字，批量转化为外链地址

以下代码即为示例：

import axios from 'axios'

// 歌单地址：https://music.163.com/playlist?id=2128245641
axios.get('https://music.163.com/playlist?id=2128245641')
    .then(r => {
        let [list, music] = [[], []]
        // 筛选出含有歌曲id的DOM结构
        list = r.data.match(/<a href="\/song\?id=[0-9].*?<\/a>/g)
        // 若歌单为空则退出
        if(!list){
            console.log('no music')
            return
        }
        // 去掉标签，保留id与歌名
        list = list.reduce((r, c) => [
            ...r,
            c.replace(/<a href="\/song\?id=|<\/a>/g, '').replace(/">/, ',')
        ], [])
        // 格式化list内容，转化为含有歌名，歌曲id，外链的对象数组
        music = list.reduce((r, c) => [
            ...r,
            {
                name: c.substring(c.indexOf(',') + 1, c.length),
                id: c.substring(0, c.indexOf(',')),
                src: `http://music.163.com/song/media/outer/url?id=${c.substring(0, c.indexOf(','))}.mp3`
            }
        ], [])
        console.log(music)
    })

// music
// [{
//     name: '丫头',
//     id: '165237',
//     src: 'http://music.163.com/song/media/outer/url?id=165237.mp3'
// },
// {
//     name: '离开你的城市后',
//     id: '863492743',
//     src: 'http://music.163.com/song/media/outer/url?id=863492743.mp3'
// }]

获取详细信息

歌曲的图片，演唱者，专辑，发行公司等都可以通过获取详细信息接口来获取：

http://music.163.com/api/song/detail/?id=[165237]&ids=[165237]&csrf_token=

将上述地址的id与ids中的歌曲id修改后请求结果示例：
