我试图从这个page解析JSON字符串，但无法通过json.loads将JSON转换为Python dict。

clean_data = html.unescape(data)
json_blob = json.loads(clean_data)
print(json_blob)

上面的代码给出了JSONDecodeError：

File "/usr/lib/python3.9/json/decoder.py", line 340, in decode
    raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 1 column 4 (char 3)

我检查JSON在JSON格式化程序中是否有效，它是有效的：https://jsoneditoronline.org/#left=cloud.c7e2f35696094a07a49afba2d18c6ad4
