我这个编码，为什么会解码不了呢？用python解码一直就报错，用网页base64在线解密的就没问题

line 27, in <module>
    json_str = base64.b64decode(s.encode("utf-8")).decode("utf-8")[1:-1]
  File "D:\python\lib\base64.py", line 87, in b64decode
    return binascii.a2b_base64(s)
binascii.Error: Incorrect padding

求助大神，要怎么解码？

你多复制了一个空格"__ ba"
