liqi.py出现致命错误

[Eric-Joker]

liqi.py 65-68:

B = base64.b64decode(dict_obj['data']) action_proto_obj = getattr(pb, dict_obj['name']).FromString(B) action_dict_obj = MessageToDict(action_proto_obj) dict_obj['data'] = action_dict_obj

将上述代码第二行getattr()添加默认值""可以略过第一次报错(ActionMJStart) {'step': 0, 'name': 'ActionMJStart', 'data': ''} 但是进入新的回合后data的值不为空时无法解码 {'step': 1, 'name': 'ActionNewRound', 'data': 'H/b75PhO8hTmKQEaJGBZ/3ppU1JxThiqHgATnE8BSWXnJL9c/dm9mqNxpsi8i/XO/bINs8/LBwbIiNxQdufk+vInt9iIo5ITP14LTCqWW0wPmL/jGxfTVc9U7tudwMQk8L2oMdTv5atY3WbxUiBvRY5o3kKJYjc0VyufGCUihW4bWF7H'}

修改后删除上述代码后两行会报另一个错：Unexpected end-group tag.

已经更换为最新版(v0.10.194.w)的最新liqi.json并进行proto→py转义

因为使用的是edge，protobuf需要3.14.0 使用protoc版本为3.14.0 使用protobufjs版本为v7.2.1(当前最新版) py3.8

proto模块解码分析wire_type为7

这个问题有解决吗？

没有

Notify 的消息体经过了 encode，需要 decode

使用如下代码

keys = [0x84, 0x5e, 0x4e, 0x42, 0x39, 0xa2, 0x1f, 0x60, 0x1c]
def decode(data: bytes):
    data = bytearray(data)
    for i in range(len(data)):
        u = (23 ^ len(data)) + 5 * i + keys[i % len(keys)] & 255
        data[i] ^= u
    return bytes(data)

修改 65-68 行中的：

- getattr(pb, dict_obj['name']).FromString(B)
+ getattr(pb, dict_obj['name']).FromString(decode(B))
