用Python中的BeautifulSoup从脚本标记中提取数据

Question

我想使用Python中的BeautifulSoup从“script”标记的代码中提取“SNG_TITLE”和“ART_NAME”值。（整个脚本太长，无法粘贴）

<script>window.__DZR_APP_STATE__ = {"TAB":{"loved":{"data":[{"SNG_ID":"126884459","PRODUCT_TRACK_ID":"360276641","UPLOAD_ID":0,"SNG_TITLE":"Heathens","ART_ID":"647650","PROVIDER_ID":"3","ART_NAME":"Twenty One Pilots","ARTISTS":[{"ART_ID":"647650","ROLE_ID":"0","ARTISTS_SONGS_ORDER":"1","ART_NAME":"Twenty One Pilots","ART_PICTURE":"259dcf52853363d79753ec301377645d","SMARTRADIO":"1","RANK":"487762","LOCALES":[],"__TYPE__":"artist"}],"ALB_ID":"13371165","ALB_TITLE":"Heathens","TYPE":0,"MD5_ORIGIN":"5cea723b83af1ff0a62d65d334b978d4","VIDEO":false,"DURATION":"195","ALB_PICTURE":"3dfc8c9e406cf1bba8ce0695a44a9b7e","ART_PICTURE":"259dcf52853363d79753ec301377645d","RANK_SNG":"967143","SMARTRADIO":"1","FILESIZE_AAC_64":0,"FILESIZE_MP3_64":"0","FILESIZE_MP3_128":"3135946","FILESIZE_MP3_256":0,"FILESIZE_MP3_320":"7839868","FILESIZE_FLAC":"21777150","FILESIZE":"3135946","GAIN":"-12","MEDIA_VERSION":"4","DISK_NUMBER":"1","TRACK_NUMBER":"1","VERSION":"","EXPLICIT_LYRICS":"0","RIGHTS":{"STREAM_ADS_AVAILABLE":true,"STREAM_ADS":"2000-01-01","STREAM_SUB_AVAILABLE":true,"STREAM_SUB":"2000-01-01"},"ISRC":"USAT21601930","DATE_ADD":1497886149,"HIERARCHICAL_TITLE":"","SNG_CONTRIBUTORS":{"mainartist":["Twenty One Pilots"],"engineer":["Adam Hawkins"],"mixer":["Adam Hawkins"],"masterer":["Chris Gehringer"],"drums":["Josh Dun"],"producer":["Mike Elizondo","Tyler Joseph"],"programmer":["Mike Elizondo","Tyler Joseph"],"vocals":["Tyler Joseph"],"writer":["Tyler Joseph"]},"LYRICS_ID":30553991,"__TYPE__":"song"},{"SNG_ID":"99976952","PRODUCT_TRACK_ID":"171067651","UPLOAD_ID":0,"SNG_TITLE":"Stressed Out","ART_ID":"647650","PROVIDER_ID":"3","ART_NAME":"Twenty One Pilots","ARTISTS":[{"ART_ID":"647650","ROLE_ID":"0","ARTISTS_SONGS_ORDER":"1","ART_NAME":"Twenty One Pilots", ...</script>

代码的思想是打印出用户名、所有可以在给定页面上找到的歌曲和艺术家的名字。

import requests
from bs4 import BeautifulSoup

base_url = 'https://www.deezer.com/en/profile/1589856782/loved'

r = requests.get(base_url)

soup = BeautifulSoup(r.text, 'html.parser')

user_name = soup.find(class_='user-name')
print(user_name.text)

这将打印用户名。

for script in soup.find_all('script'):
    print(script.contents) 

如果我理解正确，我需要的脚本是一本字典，所以我只需要找到它并得到它的内容。问题是我不知道如何具体地找到“脚本”。它没有任何属性或任何使它独一无二的东西。所以我尝试了一个循环，找到页面上的所有脚本并打印出它们的内容，但不确定如何继续。

如何在页面上只找到这个特定的“脚本”？我可以用不同的方式访问这些值吗？
