未加好友的临时消息不存在 target_id 抛出异常

[Cody-Wolf]

class Private_Message(Message):
    """私聊消息"""

    def __init__(self, cqapi: cqHttpApi, event: Message_Event, message_data: dict[str, Any]) -> None:
        super().__init__(cqapi, event, message_data)

        self.sender: Private_User = Private_User(self._cqapi, message_data["sender"])
        """发送人"""
        
        self.target_id: int = message_data["target_id"] # 抛出异常，target_id 不存在
        """接收者 QQ 号"""

实际接收的 message json

{'post_type': 'message', 'message_type': 'private', 'time': 1689303412, 'self_id': ***, 'sub_type': 'group', 'temp_source': 0, 'message_id': 61502, 'user_id': ***, 'message': '123', 'raw_message': '123', 'font': 0, 'sender': {'age': 0, 'group_id': ***, 'nickname': 'Cody', 'sex': 'unknown', 'user_id': ***}}

貌似没有 target_id 这一项？我理解这里应该是 self_id ？

重写一下Message_Event.get_message，比如从群发起临时会话

class Private_Message_From_Group(Message):
    def __init__(self, cqapi: cqHttpApi, event: Message_Event, message_data: dict[str, Any]) -> None:
        super().__init__(cqapi, event, message_data)

        self.group_id: int = message_data["sender"]["group_id"]
        """群号"""

        self.sender: Private_User = Private_User(self._cqapi, message_data["sender"])
        """发送人"""

        self.temp_source: Optional[int] = message_data["temp_source"] if "temp_source" in message_data else None
        """临时会话来源"""

    def reply(self, message: str, auto_escape: bool = False) -> None:
        self._cqapi.send_private_msg(self.sender.id, "%s%s" % (reply(self.id), message), self.temp_source, auto_escape)

    def reply_not_code(self, message: str, auto_escape: bool = False) -> None:
        self._cqapi.send_private_msg(self.sender.id, message, self.temp_source, auto_escape)

def get_message(self, cqapi):
    if self.is_private():
        if self.data['sub_type'] == 'group':
            return Private_Message_From_Group(cqapi, self, self.data)
        return Private_Message(cqapi, self, self.data)
    else:
        return Group_Message(cqapi, self, self.data)
from pycqBot.data import Message_Event

Message_Event.get_message = get_message
