Discord.py 等待消息或反应

Question

我对 Python 和 Discord.py 都很陌生，我正在尝试寻找如何让机器人同时等待用户的消息或反应。

我尝试将它们分开，但只是导致机器人在反应之前需要消息响应。

这是我正在尝试做的类似代码：

@bot.event
async def on_message(ctx):
    if ctx.author == bot.user:
        return

    if ctx.content == "$respond":
        message = await ctx.send("Waiting for response...")

        while True:
            try:
                response = #Will wait for a message(Yes or No) or reaction(Check or Cross) from ctx.author for 30 secs
            except asyncio.TimeoutError:
                await message.edit(content=f"{ctx.author} did not respond anymore!")
                break

            if response.content == "yes":
                await message.edit(content=f"{ctx.author} said yes!")
                continue
            
            elif response.content == "no":
                await message.edit(content=f"{ctx.author} said nyo!")
                continue
            
            #These are reactions
            elif str(response.emoji) == "✅":
                await message.edit(content=f"ctx.author reacted ✅!")
                continue
            
            elif str(response.emoji) == "❌":
                await messave.edit(content=f"Stopped listening to responses.")
                break

bot.wait_for 是您在此处寻找的内容。

我建议使用bot.command() 来处理命令，但这也很好。

这是您在特定条件下等待特定事件（作为第一个参数提供）的方式（如 check 参数中提供的那样）

@bot.event
async def on_message(msg):
    if msg.author == bot.user:
        # if the author is the bot itself we just return to prevent recursive behaviour
        return
    if msg.content == "$response":

        sent_message = await msg.channel.send("Waiting for response...")
        res = await bot.wait_for(
            "message",
            check=lambda x: x.channel.id == msg.channel.id
            and msg.author.id == x.author.id
            and x.content.lower() == "yes"
            or x.content.lower() == "no",
            timeout=None,
        )

        if res.content.lower() == "yes":
            await sent_message.edit(content=f"{msg.author} said yes!")
        else:
            await sent_message.edit(content=f"{msg.author} said no!")

这将导致：

监听多个事件有点意思， 用这个 sn-p 替换现有的wait_for：

done, pending = await asyncio.wait([
                    bot.loop.create_task(bot.wait_for('message')),
                    bot.loop.create_task(bot.wait_for('reaction_add'))
                ], return_when=asyncio.FIRST_COMPLETED)

你可以同时监听两个事件

以下是使用 @bot.command() 处理此问题的方法

import discord
import os
from discord.ext import commands

bot = commands.Bot(command_prefix="$", case_insensitive=True)


@bot.event
async def on_ready():
    print(f"Logged in as {bot.user}")


@bot.command()
async def response(ctx):
    sent_message = await ctx.channel.send("Waiting for response...")
    res = await bot.wait_for(
        "message",
        check=lambda x: x.channel.id == ctx.channel.id
        and ctx.author.id == x.author.id
        and x.content.lower() == "yes"
        or x.content.lower() == "no",
        timeout=None,
    )

    if res.content.lower() == "yes":
        await sent_message.edit(content=f"{ctx.author} said yes!")
    else:
        await sent_message.edit(content=f"{ctx.author} said no!")


bot.run(os.getenv("DISCORD_TOKEN"))

这会得到相同的结果。
