python - 根据用户 react 发送消息

Question

我希望我的机器人根据对用户添加的 react 发送消息。

我有代码

@commands.command(pass_context=True)
async def testhelp(self, ctx):
    try:
        Help = discord.Embed(title="Commands and Usage", description="Choose a catagory by adding a reaction", color=0x0072ff)
        Help.add_field(name='General Commands', value='😀')
        Help.add_field(name='Fun Commands', value='😆')
        Help.add_field(name='Math Commands', value='✏')
        Help.add_field(name='Anime Commands', value='🤦')
        Help.add_field(name='NSFW Commands', value='😈')
        Help.add_field(name='Music Commands', value='🎵')
        Help.add_field(name='Mod Commands', value='🔨')
        Help.add_field(name='Admin Commands', value='⚒')
        Help.add_field(name='Owner Commands', value='⚙')
        message = await self.client.say(embed=Help)
        await self.client.add_reaction(message, emoji='😀')
        await self.client.add_reaction(message, emoji='😆')
        await self.client.add_reaction(message, emoji='✏')
        await self.client.add_reaction(message, emoji='🤦')
        await self.client.add_reaction(message, emoji='😈')
        await self.client.add_reaction(message, emoji='🎵')
        await self.client.add_reaction(message, emoji='🔨')
        await self.client.add_reaction(message, emoji='⚒')
        await self.client.add_reaction(message, emoji='⚙')
    except Exception as error:
        await self.client.say('{}'.format(error))

效果很好，我只需要弄清楚如何在他们添加列出的 react 时发送不同的消息。

制作一个表情符号响应字典，然后根据该字典检查他们的 react 。下面我用Client.wait_for_reaction仅处理我们从调用该命令的人那里了解到的 react 。

responses = {'😀': 'General Commands',
             '😆': 'Fun Commands'
             '✏': 'Math Commands',
             '🤦': 'Anime Commands'}

@commands.command(pass_context=True)
async def testhelp(self, ctx):
    Help = discord.Embed(title="Commands and Usage", description="Choose a catagory by adding a reaction", color=0x0072ff)
    for emoji, name in responses.items():
        Help.add_field(name=name, value=emoji)
    message = await self.client.say(embed=Help)
    for emoji in responses:
        await self.client.add_reaction(message, emoji=emoji)
    res = await self.client.wait_for_reaction(list(responses), user=ctx.message.author)
    await self.client.say("{} you chose {}".format(res.user.mention, responses[res.reaction.emoji]))

如果您希望在回复中发送更有意义的消息，您可以编写获取上下文并发送消息的协程。

responses = {'😀': 'General Commands',
             '😆': 'Fun Commands'
             '✏': 'Math Commands',
             '🤦': 'Anime Commands'}

async def general_commands(self, ctx):
    embed = ...
    await self.client.send_message(ctx.message.channel, embed=embed)

@commands.command(pass_context=True)
async def testhelp(self, ctx):
    Help = discord.Embed(title="Commands and Usage", description="Choose a catagory by adding a reaction", color=0x0072ff)
    for emoji, name in responses.items():
        Help.add_field(name=name, value=emoji)
    message = await self.client.say(embed=Help)
    for emoji in responses:
        await self.client.add_reaction(message, emoji=emoji)
    res = await self.client.wait_for_reaction(list(responses), user=ctx.message.author)
    coro = getattr(self, responses[res.reaction.emoji].lower().replace(' ', '_'))
    await coro(ctx)
