Bot 两次发送消息

Question

我刚刚想出了如何在 discord.py 中检查反应，但现在我遇到了另一个问题。当只发生一种反应时，机器人会为两种反应发送两条消息。

        
@bot.command()
@commands.has_any_role("Franchise Owner", "General Manager", "Head Coach")
async def offer(ctx, member:discord.Member):
    embed = discord.Embed()
    embed.add_field(name="<a:Loading:768095883664424971> Incoming Offer", value=f"The <:DallasCowboys:788796627161710592> have offered {member.mention}.")

    offer_sent = await ctx.send(embed=embed)

    await offer_sent.add_reaction("<a:CheckMark:768095274949935146>")
    await offer_sent.add_reaction("<a:XMark:768095331555606528>")
    await member.send("You have been offered to the <:DallasCowboys:788796627161710592>. You have 30 minutes to accept/decline.")

    channel = ctx.channel

    def check(reaction, member):
        return member == member and str(reaction.emoji) == '<a:CheckMark:768095274949935146>'

    try:
        reaction, user = await bot.wait_for('reaction_add', timeout=1800.0, check=check)
    except asyncio.TimeoutError:
        await channel.send(f"{member.mention} hasn't reacted in time.")
    else:
         await channel.send(f"{ctx.author.mention}, {member.mention} has accepted <:DallasCowboys:788796627161710592> offer.")
         
    def check(reaction, member):
        return member == member and str(reaction.emoji) == '<a:XMark:768095331555606528>'

    try:
        reaction, user = await bot.wait_for('reaction_add', timeout=1800.0, check=check)
    except asyncio.TimeoutError:
        await channel.send(f"{member.mention} hasn't reacted in time.")
    else:
        await channel.send(f"{ctx.author.mention}, {member.mention} has declined <:DallasCowboys:788796627161710592> offer.")

    await asyncio.sleep(1800)
    await offer_sent.delete()

我最近刚刚将此添加到我的代码中以检查两种反应，但无法找出问题。

Answer 1

您的代码中没有任何内容应该发送两次消息，您可能正在运行两个版本的代码。打开任务管理器并杀死任何不需要的 python 进程或重新启动计算机

Answer 2

我很确定你运行了两次程序，以确保不会发生这种情况，我建议实施一个终止开关，这样每次重新运行程序时，你首先在 Discord 上激活终止开关，然后再次运行程序.我制作的 killswitch 示例如下：

@client.command()
async def quit(ctx):
    await ctx.send("Shutting down the bot")
    return await client.logout() # this just shuts down the bot.

Answer 3

我曾经遇到过这个问题，主要原因是：Heroku。 如果您将机器人托管在其他地方，也许您应该更改它们的前缀，以免同时触发它们！
