python - H4sIA密文解密

最近再抓包时发现返回值为一个奇怪的字符串，都是由H4sIAAAA开头，例如：
H4sIAAAAAAAACqtWKkotLs0pUbKqViouSSwpLVayMtBRKi3IyU9McUxJAcoCRfJKc3JAgimJJak++ekwgcy8ktSissSckMzcVLC2stSi4sz8PL9EEB+kplZHKSmxOBNoRLVSbjFQo9Kzyb1P9s551jHhadd8JR2l4sz0PJhxMPuNDAxqawGSwLdymQAAAA==

加解密代码如下

import gzip
import base64
# 密文
pText = "H4sIAAAAAAAACqtWKkotLs0pUbKqViouSSwpLVayMtBRKi3IyU9McUxJAcoCRfJKc3JAgimJJak++ekwgcy8ktSissSckMzcVLC2stSi4sz8PL9EEB+kplZHKSmxOBNoRLVSbjFQo9Kzyb1P9s551jHhadd8JR2l4sz0PJhxMPuNDAxqawGSwLdymQAAAA=="
text = gzip.decompress(base64.b64decode(pText))
print(f'明文: {text}')

import gzip
import base64
# 明文
text = '{"result":{"status":0,"uploadAddress":null,"updateLog":null,"intervalTime":0,"versionName":null},"basis":{"msg":"操作成功","sign":null,"status":200}}'
text = text.encode('utf-8')
pText = base64.b64encode(gzip.compress(ptext)).decode('utf-8')
print(f'密文: {pText}')
