Python -从Mu-6 musixmatch json响应中获得歌词

Question

在Python中，我试图解析来自Mu-6 parse的json响应，但是我很难理解如何访问所提供的信息，请帮助！如果有必要，我可以稍后发布JSON响应，但它是相当多的文本。

import json
from os.path json, dirname
from musixmatch import Musixmatch

musixmatch = Musixmatch(<api key>)

lyrics = musixmatch.matcher_lyrics_get('Grenade', 'Bruno Mars')


print (lyrics)

for item in jsonLyric['message']:
   for thing in item['body']:
     for stuff in thing['lyrics']:
        print(stuff['lyrics_body'])

这是我要拿回打印(歌词)的输出。

Answer 1

所以可以看到JSON响应是一个字典，它里面有很多其他字典，但是我们想要达到的是包含"lyrics_body“及其值的正文字典。

我们怎么能这么做？其实很简单。在一行中，我们可以继续调用字典并传递包含另一个键的键，因此，例如，我们想要访问的第一个字典是整个JSON响应，因此我们可以调用包含JSON响应的歌词变量，然后我们传递我们想要访问的键--在本例中是"message"，才是“message”。

print(lyrics["message"]["body"]["lyrics"]["lyrics_body"])

你的做法也很简单。您只想遍历集成字典中的每个键。

for message in lyrics:
    for body in lyrics[message]:
     if body == "body":
         for lyric in lyrics[message][body]:
             for lyrBod in lyrics[message][body][lyric]:
                 if lyrBod == "lyrics_body":
                     print(lyrics[message][body][lyric][lyrBod])

正如你所看到的，这是一样的事情，但只是需要更长的时间。

希望这能有所帮助
