Discord.py 在消息中列出用户时的反应

Question

我已经尝试解决一个问题好几天了。我想发送一个 embet naricht 并且应该在有人做出反应后立即对其进行编辑。

这里是我截取的代码：

embed = discord.Embed(title='General Information', color=16769251)
embed.set_footer(text='General information')
embed.set_thumbnail(url=message.guild.icon_url)
embed.add_field(name='Text Header ', value=all_lines[1], inline=False)
embed.add_field(name='Text Header 2: ', value=all_lines[2], inline=False)
embed.add_field(name='Accepted Users: ', 'HERE ALL USERS WITH ✅', inline=False)
mess = await message.send(embed=embed)
await mess.add_reaction('✅')
await mess.add_reaction('❌')

我已经尝试了很多东西，但不幸的是没有成功，我认为把所有东西都放在这里实在是太过分了

这里是一个例子： 之前（没有反应）

反应后：

如果我理解正确，你想要这样的东西。我一直尝试将 cmets 放入代码中，以便您更好地了解发生了什么。

由于代码是现在的，如果用户删除反应，它不会更新。如果 user_1 和 user_2 添加了反应，然后 user_1 删除了反应，它们仍然会显示，当 user_3 添加反应时，它会更新为只显示 user_2 和 user_3

您也可以在异常中的 *** 之间添加代码，以便在循环结束时最后一次更新嵌入。

另一件事是我不知道您的all_lines 是什么，所以我在测试期间将其作为字符串。

@client.command() # Correct this according to your code, if you're using bot or client
async def rtest(ctx):
    message = ctx.message

    # At first we create create the embed
    embed = discord.Embed(title='General Information', color=16769251)
    embed.set_footer(text='General information')
    embed.set_thumbnail(url=message.guild.icon_url)
    embed.add_field(name='Text Header ', value=all_lines[1], inline=False)
    embed.add_field(name='Text Header 2: ', value=all_lines[2], inline=False)
    embed.add_field(name='Accepted Users: ', value='HERE ALL USERS WITH ✅', inline=False)
    mess = await ctx.send(embed=embed)

    # And add our reactions to the embed
    emoji_list = ['✅', '❌']
    for i in emoji_list:
        await mess.add_reaction(i)

    # Create a while loop that will wait for users to react
    while True:
        users = "" # Create empty string that we need later
        try:
            reaction, user= await client.wait_for("reaction_add", timeout=60)

            # Check that if the reaction added is ✅, and if it is:
            if str(reaction) == "✅":
                mess = await ctx.channel.fetch_message(mess.id) #*** Need to fetch message again to get updated reaction information
                reaction_list = mess.reactions 

                # Check our reactions on the message, get user list for the ✅ reaction, ignoring the bot
                for reactions in mess.reactions:
                    if str(reactions) == "✅":
                        user_list = [user async for user in reactions.users() if user != client.user]
                        # Update the users string, to add user that reacted
                        for user in user_list:
                            users = users + user.mention + "\n"
                
                # Create an updated embed with different name, it's the same as before, but with users in last field
                embed_1 = discord.Embed(title='General Information', color=16769251)
                embed_1.set_footer(text='General information')
                embed_1.set_thumbnail(url=message.guild.icon_url)
                embed_1.add_field(name='Text Header ', value=all_lines[1], inline=False)
                embed_1.add_field(name='Text Header 2: ', value=all_lines[2], inline=False)
                embed_1.add_field(name='Accepted Users: ', value='HERE ALL USERS WITH ✅\n'+users, inline=False)

                await mess.edit(embed = embed_1) # Edit message to be the updated embed
        #***        

        # End the loop after the set amount of time (from timeout earlier)
        except asyncio.TimeoutError:
            break

Answer 2

你要找的是bot.wait_for，这里是一个简单的例子

@bot.command()
async def react(ctx):
    # Sending the message
    message = await ctx.send('React with ✅')

    def check(reaction, user):
        # Checking if the user that reacted is the same as the one that invoked the command
        # also checking if the reaction is `✅` and if the reacted message is the one sent before
        return user == ctx.author and str(reaction) == '✅' and reaction.message == message

    try:
        # Waiting for the reaction
        reaction, user = await bot.wait_for('reaction_add', check=check, timeout=60.0)
    except asyncio.TimeoutError:
        # If the timeout is over, deleting the message
        await message.delete()
        await ctx.send('Timeout is over')
    else:
        # If the reaction is not the one we're waiting for, send this
        await ctx.send('Bad reaction')
