如何修复 Discord.py 中的未知消息 (404)

Question

我的机器人使用 Discord.py 自动对新消息做出反应，并在 25 颗星后将它们添加到右舷。但是，在运行一段时间后会出现此错误：忽略 on_raw_reaction_add 中的异常Ignoring exception in on_raw_reaction_addTraceback (most recent call last):  File "C:\Users\timpi\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\client.py", line 312, in _run_event    await coro(*args, **kwargs)  File ".\main.py", line 36, in on_raw_reaction_add    message = await reactchannel.fetch_message(payload.message_id)  File "C:\Users\timpi\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\abc.py", line 935, in fetch_message    data = await self._state.http.get_message(channel.id, id)  File "C:\Users\timpi\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\http.py", line 223, in request    raise NotFound(r, data)discord.errors.NotFound: 404 Not Found (error code: 10008): Unknown Message这是on_raw_reaction_add事件：@bot.eventasync def on_raw_reaction_add(payload):    channel_id = int(config["channelIDMemephone"])    reactchannel = bot.get_channel(channel_id)    message = await reactchannel.fetch_message(payload.message_id)    await star_post_check(message)

如果消息不在配置文件的频道中，则搜索该频道时将找不到它。您可以添加一个检查以确保您只与该频道中的消息进行交互：

@bot.event

async def on_raw_reaction_add(payload):

    if payload.channel_id == int(config["channelIDMemephone"]):

        reactchannel = bot.get_channel(payload.channel_id)

        message = await reactchannel.fetch_message(payload.message_id)

        await star_post_check(message)
