How to crawl lyrics from spotify with syrics and spotipy

由于几乎所有的音乐网站在组织形式上都是以预先设定好的track id记录歌曲，因此与之前的思路相似，整个脚本仍然分为两个阶段：获取歌曲对应的trackid，再根据trackid获取歌词，此处，通过搜索获取trackid使用spotipy实现，而根据trackid获取歌词使用syrics实现。

利用spotipy通过歌曲名+歌手名搜索获取trackid

利用syrics通过trackid获取歌词

获取spotify中的user cookie（sp_dc）

由于我现在的chrome的版本为119.0.6045.160，已经无法通过直接在setting的cookie中查看具体cookie的数值。只能通过打开 https://open.spotify.com/ ，之后按下F12进入开发者模式，在application中的左侧菜单栏中storage中选择cookie，在其中选择open.spotify.com，之后在列出的一系列cookie中找到sp_dc，复制出来即可。

使用cookie以及trackid进行歌词获取

此处直接参考 https://github.com/akashrchandran/syrics readme中最后一段 Use as a module 获取歌词，即：

from syrics.api import Spotify
sp = Spotify(sp_dc)
sp.get_lyrics("1OOtq8tRnDM8kG2gqUPjAj")

第二行的sp_dc即是之前获取的cookie，填入程序即可。上述为Machael Jackson的Beat It的歌词。可以发现，其中含有时间轴，这正是我们需要的，分析以下返回的文本格式：

{
	'lyrics':{
        'syncType': 'LINE_SYNCED',
        'lines': [
            {'startTimeMs': '38190', 
             'words': "They told him don't you ever", 
             'syllables': [], 
             'endTimeMs': '0'},
            {'startTimeMs': '39740', 
             'words': 'come around here', 
             'syllables': [], 
             'endTimeMs': '0'},
            ....
        ],
            'provider': 'syncpower', 
            'providerLyricsId': '280721', 
            'providerDisplayName': 'プチリリ', 
            'syncLyricsUri': '', 'isDenseTypeface': False, 
            'alternatives': [], 'language': '', 
            'isRtlLanguage': False, 
            'fullscreenAction': 'FULLSCREEN_LYRICS', 
            'showUpsell': False},
    },
     'colors': {'background': -1694671, 'text': -16777216, 'highlightText': -1}, 
     'hasVocalRemoval': False}
}

可以观察到返回的json文件（已经是python的dict类型）由lyrics，colors，hasVocalRemoval三部分组成，而我们需要的带有时间戳的歌词就在lyrics的lines中，其是一个以每个时间戳为单位的list，每一个单位是一个dict，其中包含歌词的起止时间，歌词。这就是我们所需要的信息。

接下来下使用下列代码将其单独收集出来即可：

metadata = sp.get_lyrics("1OOtq8tRnDM8kG2gqUPjAj")
# print(type(a)) return is a dict type object
lyrics = metadata["lyrics"]["lines"]
