Python3 尝试解码 (base64) 然后解压缩 (gzip) 时出错

Question

我正在尝试解码 json 文本，然后在解码后使用 gzip 将其解压缩但无论我如何尝试去做，我都会遇到这个错误

" File "D:\VS Code\VSC Projects\api.py", line 25, in <module>
    decoded = BytesIO(decompress(b64decode(raw)))
  File "C:\Users\paz-pc\AppData\Local\Programs\Python\Python39\lib\base64.py", line 80, in b64decode
    s = _bytes_from_decode_data(s)
  File "C:\Users\paz-pc\AppData\Local\Programs\Python\Python39\lib\base64.py", line 45, in _bytes_from_decode_data
    raise TypeError("argument should be a bytes-like object or ASCII "
TypeError: argument should be a bytes-like object or ASCII string, not 'dict'

这是我的代码：

import requests
from mojang import MojangAPI
from pprint import pprint
from base64 import b64decode 
from gzip import decompress
from io import BytesIO


name = str(input("Enter your name of choice >>>"))

api_key = "cant show you the key"
uuid = MojangAPI.get_uuid(name)
request_url = (str("https://api.hypixel.net/player?key=" + api_key + "&uuid=" + uuid))

hydata = requests.get(request_url).json()

raw = hydata["player"]["stats"]["Pit"]["profile"]["inv_contents"]

file1 = open("ProfessionalNames.json", 'w')
file1.write(str(raw))
file1.close()
file2 = open("ProfessionalNames.json", 'r')

decoded = BytesIO(decompress(b64decode(raw)))

pprint((decoded))

这就是 ProfessionalNames.json 中的内容，也就是我要解码 (base64) 然后解压缩 (gzip) 的内容

Answer 1

这里没有base64。 'data' 成员只是 gzip 文件的一个字节字符串。它们存储为有符号整数，因此必须将它们转换为无符号整数才能进行处理。解压后无法识别文件格式，但里面确实有一些可读的字符串。

raw = hydata["player"]["stats"]["Pit"]["profile"]["inv_contents"]
by = bytes([i if i >= 0 else 256+i for i in raw['data']])
decoded = decompress(by)
