群工具进入游戏 getGroupEnterInfo这个接口获取的加密数据 ，去解析换取群唯一标识，换取的为空，请问为什么
iv":"rI7IxmApxjLIZBnZRlVo0w==",
"encryptedData":"64NNvId913SBItQGZHLOJ3xvSIkmQvQ3z4aL7aFDroErdW4Og4Xmmqfcyh75vpVv",
"cloudID":"40_wBBiNMrKI4iZn-I2ImLAylKHLtljQlpEVVJ8JxjCyUE_S6xz41jipQrGZjM"
sessionKey为IU4nr8OLkTo0n+btL0+oWQ==
python脚本：
def AesDecode():
raw_iv = b64decode("rI7IxmApxjLIZBnZRlVo0w==")
raw_encrypt = b64decode("64NNvId913SBItQGZHLOJ3xvSIkmQvQ3z4aL7aFDroErdW4Og4Xmmqfcyh75vpVv")
key = b64decode("IU4nr8OLkTo0n+btL0+oWQ==")
cipher = AES.new(key, AES.MODE_CBC, raw_iv)
pt = unpad(cipher.decrypt(raw_encrypt), AES.block_size)
print(pt)
+1 ，期待回复~
