刚开始学习 一个爬音乐的python代码报错 不明白怎么回事

报错内容：Traceback (most recent call last):
File "C:\Users\caibin\Desktop\Python\爬音乐.py", line 44, in
main()
File "C:\Users\caibin\Desktop\Python\爬音乐.py", line 37, in main

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

刚开始学 想问一下这是怎么回事

json.load出的问题,text内容不是json格式解析出的问题
