以某云为例，其实不太想写出来，用多了可能不灵了。

构造header

因为是通过网页版抓取

r = requests.Session()
r.headers = {
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
    'Accept-Encoding': 'gzip, deflate, br',
    'Accept-Language': 'zh-CN,zh;q=0.9,en;q=0.8',
    'Connection': 'keep-alive',
    'Referer': 'https://music.163.com/',
    'Upgrade-Insecure-Requests': '1',
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'
}

获取歌曲id

以下代码是获取特定歌手的热门歌曲id，歌手的id从网址上看。

def get_songs(singer_id=6470):
    url = 'https://music.163.com/artist?id={}'.format(singer_id)
    rc = r.get(url)
    if rc.status_code == 200:
        html = bs4.BeautifulSoup(rc.text, 'lxml').select('ul.f-hide li a')
        names = []
        ids = []
        for i in html:
            names.append(i.getText())
            ids.append(re.search('id=([0-9]+)', str(i)).group(1))
        print(names)
        print(ids)
        return zip(ids,names)

获取歌词

根据歌曲id获取，这里重新建立了requests，估计用之前的Session也没问题。

def get_lyric(song_id=27904290):
    url = 'https://music.163.com/api/song/lyric?id={}&lv=-1&kv=-1&tv=-1'.format(song_id)
    headers = {
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'
    }
    print('== 下载{}的歌词...'.format(song_id))
    # rc = r.get(url)
    rc = requests.get(url, headers=headers)
    if rc.status_code == 200:
        result = rc.json()
        if result.get('uncollected', False) or result.get('nolyric', False):
            print('暂无歌词')
            return ''
        lyric = rc.json()['lrc']['lyric']
        reg = re.compile(r'\[.*\]')
        lyric = re.sub(reg, '', lyric).strip()
        return lyric

循环抓取

间隔给个5到15秒，还可以。给出歌手列表，就循环把所有热门歌曲歌词抓取并保存。

if __name__ == '__main__':
    singer_list = [4950,4406]
    for singer in singer_list:
        dir_name = singer_dict[str(singer)] # 歌手目录
        if not os.path.exists(dir_name):
            os.mkdir(dir_name)
        songs = get_songs(singer)
        for sid, sname in songs:
            sname = sname.replace('/', '-') # 防止出错
            if os.path.exists('{}/{}.txt'.format(dir_name, sname)):
                print('歌曲已有，跳过')
                continue
            lyric = get_lyric(sid)
            if lyric:
                with open('{}/{}.txt'.format(dir_name, sname), 'w+', encoding='utf-8') as f:
                    f.write(lyric)
                    f.close()
                    print('歌曲：{} 已经保存完毕'.format(sname))
            time.sleep(random.randint(5,15))
