[提问] 私信消息在日志中能看到但是无法触发回复

[xxynet]

Python 版本： 3.10

模块版本： 17.3.0

运行环境： Windows / Linux / MacOS
Windows

---

代码如下：

    session = Session(credential, debug=True)

    @session.on(EventType.TEXT)
    async def handle_text(event):
        print(f"收到来自 {event.sender_uid} 的消息: {event.content}")
        await session.reply(event, f"您说: {event.content}")


    asyncio.run(session.start())

私信发了消息在日志中能看到但是无法触发回复，deepwiki分析说

从你的日志可以看到：

初始化时获取的会话信息：'ack_seqno': 2143087447486472（已读到的位置）
初始化时的 max_seqno: 2152132631875595（最新消息位置）
你发送"测试消息"后的新 max_seqno: 2152135785979907
但 fetch_session_msgs 使用 begin_seqno: 2152132631875595 请求，返回 messages: None
问题的本质：这些消息的 msg_seqno 都小于或等于 ack_seqno（已读位置），所以 Bilibili API 认为这些是"已读消息"，不会返回。 session.py:542-545

解决方案：

你需要在另一个账号发送消息后，在你的 bot 账号上不要点开这个会话（不要标记为已读）。这样 ack_seqno 就不会更新，新消息才能被获取到。

但测试全程未在其他设备登录bot账号

日志如下：

这是模块的问题，准确来说是接口的小变动导致的问题。

在这个字典中添加 "size": 30 字段即可修复。
